FUNCTION SWITCHES AND JUMPERS  
UNDERSTANDING THE INPUT FUNCTIONS  
SETTING THE VOX AND MUTE JUMPERS  
DUAL VOX AND DUAL MUTE - The Amplifier provides two inde-  
pendent VOX (V1 & V2) and two MUTE (M1 & M2) SYSTEMS  
JUMPER SETTINGS - The VOX and MUTE Functions are  
SWITCHED-ON or OFF by setting the JUMPERS on the VOX (A)  
and MUTE (B) SOCKET. See Fig. 8A.  
FUNCTION SOCKETS - EACH INPUT IS PROVIDED WITH A  
VOX (V1 & V2) AND A MUTE (M1 & M2) SOCKET.  
The SOCKETS are located on the Main PCB inside the Amplifier  
as shown on the SWITCHES and JUMPERS LOCATION DIA-  
GRAM in this Manual. Each Socket is identified by an ID NUMBER  
and the FUNCTION and DEFAULT settings are listed on the  
FUNCTION SWITCHES and JUMPERS DEFAULT SETTING  
TABLE in this Manual.  
INPUTS VOX AND MUTE FUNCTION - All Inputs including the  
Module provide 2 - VOX SEND and 2 MUTE RECEIVE functions.  
The VOX and MUTE functions are SWITCHED-ON, on each Input,  
by Internal Jumpers provided for each Input. Two VOX BUSS  
SEND (V1 & V2) and two MUTE BUSS RECEIVE (M1 & M2) can  
be independently or simultaneously SWITCHED-ON to suit the  
application requirement.  
TO SET: Lift the Jumper and reset as required. making sure that  
the JUMPER is properly positioned over the two shorting pins.

More than one JUMPER may be used on a VOX SOCKET as  
shown below. In this example both the VOX 1 and VOX 2 functions  
are SWITCHED -ON when the Input is activated. For this purpose  
additional JUMPERS are packed with each Amplifier.  
The figure below shows how the VOX 1 Logic Switch and the  
MUTE 2 Logic Switch are SWITCHED-ON by moving the Jumpers  
from the OFF position to the V 1 and M 2 position. When the Input  
is activated by a Source signal the corresponding VOX Signal is  
sent to the V1 BUSS.When the VOX 2 is activated by another Input  
the MUTE Signal is present on the MUTE 2 BUSS and it will

ADDRESSABLE DUAL MUTING SYSTEM  
DIRECT MUTING  
DUAL MUTING SYSTEM - The Amplifier is equipped with a DUAL  
noiseless, fast acting Logic MUTING Switching System. When any  
of the INPUTS are activated and a Signal is present on a given  
INPUT and either VOX 1 or VOX 2 or BOTH are Switched-ON  
(using internal Jumpers) then the MUTE 1 or MUTE 2 BUSS or  
BOTH are ACTIVE. If any of the INPUTS have the MUTE 1 or  
MUTE 2 Switched-ON (by Internal Jumpers) then the INPUT (or  
INPUTS) will be MUTED according to the Jumpers Setting. Once  
the SIGNAL-ON on the ACTIVE INPUT is terminated the normal  
functions are automatically restored on all muted inputs.  
DIRECT MUTING - Direct Muting may be accomplished by short-  
ing the MUTE 1 and MUTE 2 Terminals to the G Terminal through  
an external switch. Each time the Muting Switch is closed the cor-  
responding MUTE BUSS is activated.

CONNECTING TO AN EXTERNAL EQUALIZER  
The Amplifier is equipped with an External Equalizer Link  
to allows the use of an External Equalizer for applications  
requiring Frequency Selective Acoustic Correction. The  
Amplifier is furnished with the two jacks of the Link bridged  
by a SELECTOR SWITCH. When the EQ LINK Switch  
(REFERENCE 12) is the IN position the internal  
Preamplifier to Amplifier Link (Reference 13) is broken  
allowing the insertion of an External Equalizer.

the Equalizer in close proximity to the Amplifier. Avoid  
mounting the EQ on top of the Amplifier unless is Rack  
mounted.  
2) Be sure that the Amplifier input controls and the EQ level  
control are set at zero prior to turning the system On.  
3) The Amplifier TONE BY PASS SWITCH (Reference 17)  
should be set to ON ( linear response position).  
4) Carefully adjust the EQ Level Control to avoid distortion  
caused by excessive signal boost.

The Amplifier features two independent Remote Volume Control Capability: The INPUT 4 (AUX 1) Remote Volume (Reference 26) and  
the MASTER REMOTE VOLUME CONTROL (Reference 11). A 10 K ohm Potentiometer is required for either control. Mount the 10 K  
Pot on a suitable Wall Plate or any other convenient surface and connect to the Amplifier RVC Terminals as shown in the Diagram. The  
Paso Model RVC10W Decora Style Remote Volume Control may be used.  
INPUT 4 (AUX 1) OPERATION  
When connected the Remote Volume adjusts the INPUT 4 (AUX 1) Level only. Usually this input is utilized for the Music Source (Satellite  
Receiver, CD Player, etc.).  
MASTER VOLUME OPERATION  
The Control is a Master Volume and controls all the Inputs of the Amplifier with the exception of the MOH and ZONE 1 and ZONE 2  
Outputs.  
CABLE  
To connect the Remote Control to the Amplifier use a two conductor wire not less than AWG 24. While the Remote Volume System uses  
DC rather than audio caution should be exercised in the layout of the wire. Always avoid routing next to power lines. If the total wire resist-  
ance exceeds 3 K ohm the Volume may not go down to zero.

MOH - 600 OHM SYSTEM  
MOH/ZONE 1 SOURCE SELECTOR  
Most Phone systems operate on a 600 ohm Input Impedance, if the  
Impedance required is 600 ohm connect the Amplifier to the Phone  
System MOH by using the diagram above (Reference 3).  
The Source for the MOH/ZONE 1 Amplifier can be selected  
from either the AUX 1 - AUX 2 or MODULE by setting the  
JUMPER SET No. SW702 provided for this purpose. Default  
Setting for this Jumper Set is AUX 1. To change the setting do  
the following:  
MOH - 8 OHM, 1 WATT SYSTEM  
Some older Key Phone systems require a 1 watt Power Output having  
an Output Impedance of 8 ohm to drive the Music on Hold feature. If  
the Impedance required is 8 ohm connect the Phone system MOH to  
the 8 ohm, 1 Watt MOH Output of the Amplifier (Reference 4).  
CABLE  
Use a cable consisting of a twisted pair of at least AWG 18. Use care  
in extending the cable and avoid routing near power lines, fluorescent  
lights and other systems that may generate a disturbing electric field.  
ACCESS TO THE MOH/ZONE 1 INPUT SOURCE SETTING  
1) Remove Power Cord from AC Outlet.  
2) Remove the three screws on each side of the amplifier  
holding the amplifier cover.  
3) Lift Cover and locate the Jumpers Set No SW702 on the  
MOH Amplifier Board (see Function Switches Jumpers  
Location Diagram).

INPUT SOURCE SELECTOR  
The Amplifier is equipped with two independent 1 Watt, 8  
ohm Outputs designated ZONE 1 (Reference 4) and ZONE  
2 (Reference 5). The Outputs may be utilized to power up to  
4 speakers in various combinations as described in the dia-  
grams on the next page. This feature will provide a SEC-  
OND and THIRD ZONE (in addition to the main output) with  
up to 1 Watt of output power and will amplify only the  
Source from either AUX 1 - AUX 2 or MODULE (see input  
source selection) and will not be affected by the Paging  
(from MIC or TEL), VOX or MUTING.  
Independent JUMPER SETS for ZONE 1 (SW702) and  
ZONE 2 (SW701) are available to select the Input Source  
for the two 1 Watt Amplifiers.  
DUAL PROGRAM SOURCE CAPABILITY  
If desired separate program Sources may be used for  
ZONE 1 and ZONE 2.  
EXAMPLE: Use the program source from AUX 1 for ZONE  
2 and the program source from AUX 2 for ZONE 2.  
Select the Input Source desired by following the instructions  
in the MOH Amplifier Source Selection section.  
It can be used in any area (up to 1 Watt) where only a  
Program Source is desired uninterrupted by Paging.

RESTAURANT/DINER WITH MUSIC AND JUKEBOX - APP. DATA 121  
APPLICATION  
This  
Note  
illustrates  
a
typical  
installation  
in  
a
Restaurant/Diner/Lounge using Background Music and a Jukebox.  
The Background Music can be automatically interrupted when the  
Jukebox is activated. The Background Music is then automatically  
restored once the Jukebox stops playing.This built-in feature of the  
DMS Amplifier eliminates the need of any external device.  
PAGING MICROPHONE  
PRIORITY PAGING MICROPHONE - A Low Impedance Dynamic  
Microphone can be connected to the Amplifier INPUT 1. The  
Microphone Input can be set to provide Priority Paging over both  
the Music Program and the Jukebox if activated. Optionally Paging  
may be generated from the Phone system if desired.  
PAGING FROM THE PHONE SYSTEM  
PRIORITY PAGING FROM THE PHONE SYSTEM - Paging may  
be generated from a Phone System by using the TEL INPUT of the  
Amplifier. The TEL INPUT can be set to provide Priority Paging  
over both the Music Program and the Jukebox if activated.The TEL  
INPUT provides a 600 ohm Transformer balanced Phone interface.  
MUTE 2 DELAY  
The Jukebox Configuration utilizes the VOX/MUTE 2 Buss. In order  
to prevent the premature JUKEBOX/MUSIC SOURCE switching  
(the Music Source cuts-in while the Jukebox is active) a MUTE 2  
DELAY TRIMMER is available on the Rear panel to increase the  
MUTE 2 DELAY as necessary. The MUTE 2 DELAY can be adjust-  
ed from 3 to 30 Seconds.  
EXAMPLE: If the Jukebox is playing and the Tune has a long pause  
or the long pause while the Jukebox is cycling between CD’s it is  
possible that the Music Source (Background Music) may cut-in  
causing annoying and unwanted chatter while the Jukebox is still  
active.To prevent this problem the MUTE 2 TIME DELAY should be  
adjusted accordingly.  
M U T E 1  
M U T E 2  
G R O U N D  
JUKEBOX REMOTE VOLUME CONTROL  
A Jukebox Remote Volume Control may be provided to adjust the  
Output Level independently from the Background Music Source.  
The Jukebox Music Level should be set in accordance to the ambi-  
ent noise which may change during peak business hours.The AUX  
1 Input (used for the Jukebox) is equipped with a Remote Volume  
Control Feature. Use the optional PASO Model RVC10W (10K)  
Volume Control mounted on a single gang plate.  
U N M U T E  
MUSIC ON HOLD  
The Zone 1 Amplifier provides a separate 600 ohm Transformer  
Balanced Music on Hold Output for the Telephone system. If the  
Zone 1 Input Selector Switch is set to Input 3, the MOH Output  
receives only the PROGRAM from the the MUSIC SOURCE with-  
out Paging or the Jukebox interruptions.

AUTO SERVICE STATION C - STORE - APP. DATA 123  
APPLICATION  
This Note illustrates a typical Auto Service Station  
C-Store application. The size of the Service  
Station and the number of Gas Pump Islands to  
cover will determine the amount of outdoor  
Waterproof Speakers required and the Power  
Output of the Amplifier.  
GAS PUMP OUTDOOR SPEAKERS  
40 WATT SYSTEM EXAMPLE - The PASO Model  
C55DMST Waterproof Music Speaker is recom-  
mended.Typically each Speaker should be tapped  
at 5 Watt. In this configuration up to 8 Speaker  
may be used with the Model DMS3040 40 Watt  
Amplifier for distribution of Music and Messages  
at the Gas Pumps.  
For larger systems use a higher power Amplifier  
and the additional quantity of speakers required.  
C _ STORE INDOOR SPEAKERS  
The Amplifier is equipped with two independent 1  
Watt , 8 ohm Amplifiers = ZONE 1 and ZONE 2.  
C-STORE - Up to 4+4 Ceiling Speakers may be  
utilized indoors in the Store area, Rest Rooms or  
other area such as a separate concession. By uti-  
lizing the separate (2) 1 Watt Amplifiers as a first  
and second zone, only the Music program will be  
distributed inside the Store. This avoids the con-  
tinuous and annoying repeating of the messages  
in the indoor areas. The output level may be  
adjusted by the 1st and 2nd Zone Level Control.  
ZONE 1 - ZONE 2 PROGRAM SOURCE SELEC-  
TOR
