Fea t ur e Over view

The Century Series has the audio quality, features, and func-

tions demanded by the modern music professional. The Vx is

the first Crest Console to use VCA's, includes all of the basic

features found in other Century Series consoles and adds an

extensive meter bridge and a set of advanced new features to

accommodate more demanding applications.

Vx features:

• Full function SOLO monitoring system with dedicated level

meters. User choice of PFL or AFL from any source, both in

stereo where appropriate.

• Mixing flexibility via 8 conventional Audio Groups & 8

VCA Groups, permitting enhanced Mix Integrity, Wet / Dry

Blending, and True Post Effect Sends.

• Standard frame sizes include 32, 44, 52, and 64 positions.

(20, 32, 40, and 52 inputs respectively). The Master section

occupies four positions and Groups occupy eight positions.

• 4 Scene Mutes, designed to mute both pre- and post-fader

input channel signals including those Aux sends used as moni-

tors. When muted, PFL circuitry, Peak, Level, and Dynamic

Signal Present LED indicators remain fully operational..

• Any frame size may be ordered short loaded for later expan-

sion.

• Direct access to Group Mix buses allows expander mixers to

be easily patched into the console.

• Comprehensive Meter bridge provides signal level metering

of LEFT, RIGHT, CENTER/MONO, SOLO LEFT, SOLO

RIGHT, and 8 SUBGROUPS. The LEFT, RIGHT, CEN-

TER/MONO and SOLO meters are of a larger size and are

centered on the meter bridge. For 64 and 52 positions frames

sizes only, metering is also provided for the 8 AUX SENDS.

All level meters are of the mechanical moving coil type, are

referenced to +4 dBu, and are illuminated by long-life LED’s.

• Majority of audio Inputs and Outputs balanced on XLR con-

nectors.

• Twin power supply capability with automatic changeover

backup for uncompromised reliability. Second power supply

optional.

• Optional Stereo Input modules available, useful for remote

feeds, effects returns, and other mic or line level signals requir-

ing stereo handling.

• 8 Matrix Outputs Standard, useful for the creation of inde-

pendent mixes using the main outputs and External Input as

signal sources.

• Comprehensive Talkback section allows access to all primary

console outputs. Additional access provided to an external

location such as an on-stage monitor mixer system. External

signals can also be assigned into the talkback system including

Oscillator and Pink Noise source inputs.

• Discreet bus assignments and L-C-R (Left-Center-Right)

panning. Input channels and Effects Returns incorporate an

uncompromised bus assignment section. Features include true

L-C-R panning, standard panning, clean mono bus, discrete

bus assigns, and panable stereo bus assigns.

• 8 Discrete Aux Sends, each with On/Off Control & Status

LED.

• Variable Hi-Pass filter on input channels allows for precise

control over a signal’s unwanted low frequency content.

• Channel inserts are implemented using separate 1/4" TRS

jacks for send and return. An insert switch with indicator LED

allows A/B comparisons and signal processor bypass.

• Switchable Q on Hi Mid and Lo Mid EQ bands adds more

flexibility to an EQ circuit that already offers four sweepable

bands and selectable peak/shelving on the Hi and Lo bands.

• Each input channel features a five-segment LED array,

including a signal present LED, three signal level LEDs and a

peak indicator.

• SSM/PMI high-quality preamplifiers on balanced micro-

phone/line inputs for uncompromised audio quality and relia-

bility. All IC’s within the audio path are socket mounted for

easy upgrade or service.

• 48 Volt switchable phantom power on all microphone inputs.

• Optional transformers available on all microphone inputs and

on Group, Left/Right, Mono, Aux, and Matrix outputs.

age to attenuate or boost an audio signal. The VCA DOES NOT

What this enables is control over VCA Subgroups 1 thru 5 by

have Audio signal present in the fader. The fader only controls

the amount of voltage (level) an input can have to a mix buss

or summing amp. To get the input back out of the console, the

input needs to be assigned to the Stereo Mix Buss or an Audio

Group. Assigning a fader only to a VCA will not allow an

input to get out of the console.

using VCA Subgroup 8 as the Band Master. Once set, the

entire blend (band mix) can be brought up or down by moving

only VCA 8. “Mix Integrity” is now possible. Some term this

as ‘poor man’s automation’, because any input assigned to

VCA subgroup 8 will electronically “move” as if the faders

had been physically moved.

Note that any inputs assigned to two (2) VCA Subgroups are

controlled by BOTH VCA Subgroups.

Audio Submasters DO have audio signal present in the fader.

All inputs assigned to an Audio Submaster are summed, and

are useful as line-level returns and sends, and group process-

ing. Audio Submasters are especially useful as effects returns

when inputs have been exhausted.

Tr ue P os t Effect S ends

This section will examine what happens to the effect (Aux)

sends when the Audio Subgroups are used as in the example

above. In this example, Aux 1 is used for the Main Reverb,

Aux 2 for Drum Reverb and Aux 3 for the Delay. A Drum

Solo will be employed for the example here. The effects are in

Audio Group 6, making it possible to pull the effects down

between songs, or if the wet / dry balance needs to changed.

M ix Int egr it y

VCA’s are useful when a mix must be brought up or down

without changing the relationship between Subgroups.

Depicted below is a typical mix in Mono, with the Audio

Subgroups configured as follows:

The band is cooperating at this point and the Audio Submasters

are back to the starting point. The drummer is about to take a

big solo for the night, and it will be necessary to turn Audio

Subgroup 1 up 10dB. At this point, one of two things must be

done:

1-DRUMS

3-GUITAR

5-KEYS

2-PERCUSSION

4-BASS

6-EFFECTS

7-BACKRND VOCALS 8-LEAD VOCAL

Although a suitable mix has been obtained during soundcheck,

during the performance the band turns up their level about

+10db, and everything will need to be turned down quickly.

Typically, the engineer would bring down the master or grab

all 8 group faders with both hands and pull everything down. A

quick listen, and a look at the relative levels of the Audio

Submasters will indicate that the mix has been compromised,

and the integrity of the mix will need to be restored.

1) Turn up Subgroup #6 10db also to keep the reverb at the

same relation it was to the “DRY” drum sound before it

was turned up; OR

2) Turn up all Aux sends on the drum inputs 10dB (not

desirable); OR

3) Turn up all Drum inputs 10dB on the input faders.

The reason that one of these options must be chosen is because

effects busses (aux busses) do not and will never increase or

decrease in level when an Audio Submaster is turned up or

down. This alone is the most critical aspect of why Audio

Submasters are not acceptable for controlling a mix. What has

been described here is a drum solo situation; imagine the prob-

lems encountered when adding the other Submasters!

This all can be easily handled with VCA’s. With inputs

assigned to VCA’s, the entire band mix can be turned up or

down with 1 fader. The relationship between the VCA Groups

(the ‘mix’ or the ‘blend’) will remain the same, without physi-

cally moving the Subgroups, and will remain exactly the same

at all levels. All that is needed is to move a “Band Master”

VCA.

To accomplish this, inputs would be assigned to VCA Groups.

The same basic Subgroup assignments shown previously

would be used in the Audio Subgroups, but with 2 major dif-

ferences:

A common solution used when using Audio Submasters is to

mix on the input faders. This way all effects will “follow” the

moves made on the faders in direct proportion. Although it is a

painful way to mix, some engineers will always mix on the

input faders.

Group #8 is labeled BAND MASTER;

the Lead Vocal is assigned directly to the LEFT &

RIGHT MASTERS, and is not assigned to a Group.

The levels of all VCA Subgroups would be set at “0dB” (nom-

inal). This is because “0dB” is where VCA’s operate best. It is

the “Unity” position. (Indicated by the "Unity" LED).

A stereo mix can be obtained immediately, because the inputs

can be assigned directly to the STEREO MASTER. In addi-

tion, all “band” input faders must be DOUBLE ASSIGNED to

2 VCA Subgroups. In other words, all Band inputs assigned to

(continued on page 8)

ENTURY SERIES

One of the major benefits of VCA’s is that any move made on

a VCA Subgroup will cause all inputs assigned to that

Subgroup to move in direct proportion with it. Inherently, all

effects assigned (or turned up) on any input modules that are

controlled with VCA’s will “follow” any moves made in the

exact proportion also. If a subgroup is moved “3db”; then all

effects will move “3db”. The wet/dry blend always remains the

same.

W et / Dr y Blending

The word “blend”, is used to describe the relationship between

the dry “mix” (all inputs minus the effects) and the wet “mix”

(all the effect returns).

There is no such thing as Wet/Dry Blending when using Audio

Submasters, unless mixing is done on the inputs. Any time an

Audio Subgroup is moved the wet/dry blend is destroyed, as

there is no Mix Integrity or True Post Effect Sends. The only

true way to change the wet/dry blend would be to adjust the

Master Output on any effect send. This is also an undesirable

way to adjust a mix.

With VCA’s assigned as in the previous example, it is a simple

task to adjust the balance between the ‘dry’ and the ‘wet’ by

simply moving VCA Subgroup 6. Any moves made with the

Band Master VCA (Subgroup 8) will cause everything will fol-

low in direct proportion. The same is true for the background

vocal mix (on VCA Group 7). If VCA Group 7 is moved up or

down, all reverbs and delays turned up on all background vocal

inputs will remain in the exact proportion you have estab-

lished. Therefore, once a wet/dry blend is established, it can

never be changed by moving VCA groups.

Now it is possible to mix with 4 faders, or if you will, 4

VCA’s: Lead Vocal, Background Vocals, Band and Effects. Of

course, there will always be small adjustments that need to be

made on the input faders from time to time to tweak a mix.

It has been suggested that when attempting to mix on VCA’s

for the first time, the operator turn off the sound system and

monitor with headphones. All the subtle nuances achieved can

then be heard, and the ability to easily control a mix will

become obvious. C

Supply Identification

Twin Supply Operation

The type of power supply can be identified by the model num- When twin supplies are in use for automatic back-up, then the

ber shown on the back of the chassis and panel label.

ground links on both supplies should be fitted.

In a situation where the safety ground to the console chassis

has been connected and the ground path via the power supply

is causing a hum-loop, then disconnect the ground links on

BOTH power supplies.

Power Requirements

The Century Series power supplies have certain electrical

requirements to operate properly. If possible the power supply

should be connected to a dedicated circuit. Should any other

appliance on the same circuit draw enough current to overload

the circuit, the breaker or fuse will trip causing loss of power

to the console. Note the maximum current draw specifications

at right. Be sure that the circuit to which you connect the sup-

ply can handle the draw.

Console and Power Supply Grounding

Console chassis ground is electrically connected to audio

ground, pin 1 of XLR connectors and 1/4" sockets and to the

terminal 'CONSOLE GROUND' at the rear of the power sup-

ply. The AC third wire connection in the power supply cable

connects the metal chassis of the power supply to safety

ground. This connection should never be disturbed. Hazardous

voltages exist inside the power supply which require the case

to be grounded. When rack-mounted, the power supply ground

may transfer to the rack case thru the front fixing screws,

though this connection is not reliable. When a console is con-

figured within a complete sound system the grounding require-

ments may call for the ground link to be disconnected. This is

permissible only when an alternative ground path has been

provided. If in doubt seek the advice of an experienced electri-

cal engineer.

The power switch on the supply front panel is also a circuit

breaker, there is no power fuse. Should the supply ever shut

down, or trip at start up, simply push the switch to the off posi-

tion and then on again.

Ground Linking

Safety Cons iderations - Each new power supply is shipped

with the AC third wire ground connected to the console chassis

ground. The connection is made at the rear of the power supply

unit. This is necessary for safety reasons so that exposed metal

parts are grounded. In the event of a live conductor making

contact with the console chassis or the power supply chassis

then the current will flow to ground without a safety hazard

arising. Note that when the console is disconnected from the

power supply the chassis ground connection to AC third wire

ground is broken and safety protection is lost. For uninterrupt-

ible grounding, in a fixed installation for example, make a con-

nection directly to the console chassis from the safety ground.

Disconnect the ground link on the rear of the power supply.

This disconnects console ground from power supply AC third

wire ground which would otherwise create a hum-loop.

Cons ole Cooling

A dual-fan cooling configuration is included in all Vx consoles. Two fans (one at each end of the console) draw air in through the

sides of the chassis (under the sidebars). Air is distributed through the chassis via a “vortex pan”, then proceeds up through the

console modules, where the heated air exits the console chassis.

Once the console is powered up, cooling fans remain on. A rear panel switch permits the fans to be set at low, medium or high

speeds.

There are no filters to change or clean. As with any console, use in dusty/unclean environments should be avoided.

100mm linear VCA level control, adjusts the level to all

'POST' fader outputs, ie auxiliaries 1-8 selected post, AFL,

Group assigns 1-8, L, R & Mono output mixes. Local fader

movements combine with movements of any VCA Group

faders the channel is assigned to. The change in audio level is

the sum of the two. If the Group fader is closed no local move-

ments will be heard. If the Group is at -5, local fader settings

will be reduced 5dB. Refer also to Expansion and muting.

These Push-On/Push Off pots adjust signal level sent to

respective Aux buses. Pushing the switch down turns the send

on or off. An associated two color LED indicates status: OFF

indicates an 'off' state; GREEN indicates the Aux send is on,

and not muted; RED indicates the Aux send is on, but muted.

The signal source for these mixes may be selected (by Aux

bus) to be pre or post fader by the GLOBAL switches located

in the Vx Master section.

VCA Operation - Groups

The Master console VCA group faders affect the levels of any

channels assigned to a VCA group on both consoles. VCA

group faders on the Slave console are inactive, while the VCA

unity gain indicators remain functional.

Century Vx Console Expansion

The Expansion option is available for all Vx models. Two Vx

consoles may be linked in a Master-Slave arrangement.

Alternatively, a Vx may be linked to a Yamaha PM series

model, or other console.

VCA Operation - Group Mutes

Between Vx consoles, the VCA Group Mute function of the

Master console controls all channels assigned to that VCA

Group. VCA Group Mutes on the Slave console are inactive.

Included Facilities

The facilities included are:

- links for control of VCA Groups 1-8

- links for Left, Right and Mono audio mixes

- links for Scene Mute groups

- links for Solo PFL and AFL audio mixes

and Solo control

Between a Vx and a PM console, there is no transfer VCA

Group Mute function.

Scene Mute Operation

The Master console Scene Mute Master ON-OFF switches (Vx

A-D, PM 1-4) are active for all channels assigned on both con-

soles. Master switches on the Slave console are inactive. In

response to a master mute, the indicator next to the appropriate

master mute on the slave console lights.

- mode selection: Master-Off-Slave for all functions

A further option is available with the standard Vx Expansion

system. This provides direct access to the Left, Right, Mono

and Aux 1-8 audio buses.

Between Vx and PM consoles, Scene Mutes 5 thru 8 are not

transferred. Some PM models allow independent Master-Slave

selection of Scene Mutes 1-4 and 5-8.

Hardware

Active electronics for the Expansion system are located inside

the console chassis. The 56-way EDAC Expansion connector

is located in the upper chassis cut-out behind Input 1. The

Mode switch is located immediately below the Expansion con-

nector. A link cable is required, and is available in two ver-

sions, Vx-to-Vx, and Vx-to-PM. Cable length permits consoles

to sit side by side or in an “L” arrangement.

Solo Operation

The Solo meters and headphones of the Master console

respond to a Solo selection on either console. Solo meters and

headphones of the Slave console respond to a Solo selection on

the Slave console only.

Audio Linking

When fitted, the 56-way Bus expansion option occupies the

second chassis cut-out position.

The Left Right and Mono audio circuits between consoles are

high level ground-free connections. The audio paths connect

onto the appropriate summing bus in the Master console and

are controlled by the Mode switch.

All audio interfacing is buffered at line level. There are no

chassis connections in the link cable.

The audio group mixes of the two consoles remain indepen-

dent.

Outputs

The console expansion link connection includes the Left, Right

and Mono outputs. These are derived after the Matrix send

Pre/Post switches on the Output sections. The audio outputs

are not affected by the Mode switch.

(hardware set reference: Vx Expansion 76D2943-00 +

76D2977-00 July 96)

Linked Console Operation

Set up the two consoles as normal. Provide each console with

its own power supply and back-ups, then connect the link

cable. The Vx-to-Vx cable may be fitted either way around,

internal connections cross over inputs to outputs. The Vx-PM

cable has different connectors at each end.

Inputs

The console expansion link input paths to the Left, Right and

Mono summing buses are active ONLY when the console is in

MASTER mode. In Slave and Off modes the audio circuits are

gated off.

Modes

The mode switch may be set with power on or off; the system

responds immediately.

Assign the Master console with the Mode switch on the Master

console set to MASTER. Assign the slave console with the

mode switch on the slave console set to SLAVE. (Note that if

both consoles are set to Master then the system rejects both

settings, both consoles respond as slaves until one is set to

Master mode.)

When independent operation of the Slave console is required ,

select the “OFF” mode.

STEREO PROGRAM INPUT

(located above the MONO Master)

LCR PANNING

Connections are provided on the rear panel for stereo input to

the Mixes, Auxiliaries and Matrix outputs. Use this section for

music playback or special return input. Access to the Matrix

outputs is direct, bypassing the groups. On each Matrix that

requires Stereo input select the switch next to the level control

pot 'L-R / STR PGM'.

Operation of center-cluster sound systems requires panning

channels between the Left and Right sides of the main stereo

PA and between the stereo PA and the center system.

Conventional panning systems allow for L-R panning but the

center feed is either all on, full center, or all off, no center. In

practice it is necessary to balance the different sound groups

between center and sides. This requires LCR panning. Active

circuits are combined with a special multi-section pot in the

Input, Stereo Input and Group-to-mix pan sections of Vx con-

soles.

Stereo Program audio from the rear XLR connectors also pass-

es to switching contacts on the TAPE INPUT 1/4 inch sockets.

When nothing is plugged into the TAPE sockets Stereo

Program audio passes to the TAPE monitor source switch.

VCA GROUP MUTES

INPUTS and GROUPS

Normally the operation of the VCA Group Mute commands all

the channel VCAs in the group to close. The effect is that all

output assignments are faded out, also the post-fader effects

sends are faded. However pre-fader sends are un-affected. This

may be satisfactory, it depends on the effects and monitor mix

set-up at the time.

LCR pan sections include an LCR enable selector. When in

LCR mode, three outputs (Left, Right and Center) are derived

from a single input.

Pan central

100% output to Center only

100% output to Left only

100% output to Right only

Pan hard left

Pan hard Right

In a situation where a pre-fader send had to be muted with the

channel then two possible options are available.

Between hard left and center progressively less left and

more center output, no right

output.

Use the local channel Mute switch to cut the pre-fader send,

either individually or as part of a Mute Group.

Between hard right and center progressively less right and

Alternatively the console can be set so that VCA Group Mute

sends a Mute command to the channel audio switch in addition

to a fade command to the channel VCA.

more center output, no left

output.

Operation of LCR panning requires the L-R and M (mono or

center) assign switches to be selected and the LCR switch

selected.

This choice is called VCA Group Channel Mute option. It may

be set up individually for each VCA Group by selection of an

internal jumper link in the Group Output module.

The monitoring section of the console allows the center mix to

be added to the stereo mix in headphones for checking purpos-

es.

When this is set up, then operation of a VCA Group Mute

switch sends Mute commands to the channel mutes of all chan-

nels in the VCA group. The result is to turn off the post-fader

audio outputs to buses, effects etc, AND to mute the pre-fader

sends.

STEREO CHANNELS

LCR panning is provided by the Balance section of the

Width/Balance control.

Select the LCR switch and the L-R and Mono audio assign

switches. Now the inner control 'Balance' operates as an LCR

panpot:

This would be desireable if some of the pre-fader sends were

being used for foldback or effects for example.

Fully counter-clockwise = full level to L&R, none to center,

50% rotation = equal levels to L, R & Center outputs,

Fully clockwise = full level to center, no signal to L&R

Cons ole Dis a s s em bly

Though you shouldn’t have to disassemble the console, it is necessary to remove modules to change the jumper and switch set-

tings associated with the internally selectable options. The following steps detail the tasks involved when taking the console

apart.

ONE • Open t he a r m r es t .

Opening the

Armrest

To properly remove one or many modules, the black painted

armrest must first be opened. To do this, the two thumb-

screws (see diagram at right) must be loosened from below.

Once these screws are loose, slide both of them a few inches to

the side (they will only move in one direction). Once the

screws have been moved the armrest will easily roll back

exposing the module screws beneath.

TW O • Rem ove fr ont m odule

s cr ew

Once the armrest has been opened, there will be a single screw

at the front edge of the module panel holding each module in

place. Remove the screw from the module(s) you want to

remove.

Thumbscrews

THREE • Rem ove r ea r s cr ews

On the back panel of the console there are two screws holding

each module in place (see diagram at right) Remove both

screws from each module you wish to remove.

FOUR • Lift t he m odule(s ) out

As you lift the module out of the chassis three wires must be

detached before the module can be completely removed: 2

flat-wires (ribbon cables) and one ground wire.

FIVE • P ut t ing it a ll ba ck t oget her

Re-assembling a Century Series console is as easy as taking it apart, but only if you know where everything goes. If you are

going to be removing a number of modules, consider replacing the first before removing the second. Reversing the above steps

should result in the console being as well put together as it was when it left the factory.
