connections
All controls necessary for daily operation of
the DSi-8M are easily accessible on the front
panel. 8-channel monitoring allows you to
monitor either the processor or the power
amplifier’s outputs: L,C, R, Ls, Rs, Bsl, Bsr,
and Sub in any combination.

Designed to work with bi-amplified sound sys-
tems to monitor the high- and low-frequency
outputs from the left, center and right channels
Input levels for processor and power amps can
be adjusted independently
No level jumps when switching between pro-
cessor and amplifiers
Input levels from the processor and power am-
plifier can be adjusted independently. There are
no huge level jumps when switching between
processor and power amplifiers.

fier.
Specifications
Rear Panel Controls and Connectors
IEC AC Power Receptacle: Connects to an IEC

Input Impedance (Power Amplifiers Inputs):
> 50 k ohms.
Input Connector 1: 10-pin Phoenix terminal
block connects to the power amplifier speaker
outputs for the Left Surround, Right Surround,
Back Surround Left, Back Surround Right and
Subwoofer channels. This connector lets you
monitor the output of amplifiers that do not
include HD-15 connector options.
Input Connector 2: 10-pin Phoenix terminal
block connects to the power amplifier speaker
output for the Left High, Left Low, Center
High, Center Low, Right High and Right Low
channels. This connector lets you monitor the
output of amplifiers that do not include HD-15
connector options.
HD-15 Connector 6: Connects to Cl/Ch ampli-
fier.
Power Requirements: 100-240V , 50-60 Hz,
32 watts.
Optional Input Connector: 25-pin D-sub con-
nector connects to the EX output of the proces-
sor.
Front Panel Controls and Indicators
Channel Select Buttons and LEDs: Eight
pushbutton switches, one for each input
channel. Pressing a button monitors the signal
from that channel, and lights the correspond-
ing LED. Any combination of eight channels
can be selected.
Bargraph Level: Trimpot adjusts the sensitivity
of the front-panel VU Bargraph Meter.
Main Input Connector: 25-pin D-sub connector
connects to the main outputs of the processor.
“EX” Selector Switch: 8-position DIP switch.
Turn on switches 1-4 if system is without EX.
Turn on switches 5-8 if system is with EX. This
routes the correct Ls/Rs inputs to the DSi-8M
circuitry.
Volume Control: Rotary potentiometer with
knob controls the volume of the internal or
external speaker. Has no effect on the VU
Bargraph Meter display.
Amplifier Level Control: Trimpot adjusts
the level of the input signals from the power
amplifiers.
Processor Level: Trimpot adjusts the level of
the input signals from the processor.
Construction
Chassis: Steel.
Processor/Amplifier Selector Switch and
LEDs: Pushbutton switch with corresponding
LEDs selects inputs from cinema procesor or
power amplfiers for monitoring.
Dimensions: EIA Standard 19-inch rack mount
width (EIA RS-310-B), 3.5 inches (8.9 cm) high
and 9.625 inches (24.4 cm) deep behind front
mounting surface.
Outputs to Power Amplifier Inputs: The six
HD-15 connectors in this section connect to
DSi amplifiers for both input and output sig-
nals. The HD-15 connectors have two func-
tions:
VU Bargraph Meter: 12-segment meter dis-
plays input level of selected channels from –40
VU to +3 VU. May be calibrated by the rear-
panel trim adjustment. Operates independently
of the Volume Control.
