DSi 8M Cinema System Monitor
Operation Manual
2 Controls, Indicators and Connectors
2.1 Front Panel Controls, Indicators and
Connectors
A. 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 corresponding LED. Any combination of eight
channels can be selected.
B. Volume Control
Rotary potentiometer with knob controls the volume of the
internal or external speaker. Has no effect on the VU
Bar graph Meter display.
C. Processor/Amplifier Selector Switch and LEDs
Pushbutton switch with corresponding LEDs selects inputs
from cinema processor or power amplifiers for monitoring.
D: VU Bargraph Meter
12-segment meter displays input level of selected channels
from –40 VU to +3 VU. The meter can be calibrated by the
rear-panel trim adjustment, which operates independently of
the Volume Control.
E. Test Jack
1/4” phone jack lets the user monitor the audio output of the
DSi 8M. Inserting a mono or stereo 1/4” phone plug here
disables the internal speaker and routes the audio output to
the Test Jack.
F. Internal Speaker
For convenient monitoring at the monitor panel.
G. Power Switch and Power LED
Rocker switch turns power on or off. LED illuminates when
power is on.
The DSi 8M is intended to be used with DSi Series
amplifi ers which use on-board crossovers for any
loudspeaker application. Therefore, there is no internal
crossover option for the DSi 8M System Monitor.

H. IEC AC Power Receptacle
Connects to an IEC AC power cord.
I. Input Connector
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.
J. Input Connector
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.
K. Amplifier Level Control
Trimpot adjusts the level of the input signals from the power amplifiers.
L. Outputs to Power Amplifier Inputs
The six HD-15 connectors in this section connect to DSi amplifiers for both input and
output signals. The HD-15 connectors have two functions:
1. Connect DSi 8M outputs to DSi amplifier inputs.
2. Connect DSi amplifier outputs to DSi 8M inputs for monitoring.
Using VGA cables, the HD-15 connectors can be connected to Crown DSi power
ampli fier HD-15 connectors as described below.
HD-15 Connector 1: Connects to Left Surround/Right Surround amplifier.
HD-15 Connector 2: Connects to Back Surround Left/Back Surround Right amplifier.
HD-15 Connector 3: Connects to Right Low/Right High amplifier.
HD-15 Connector 4: Connects to Subwoofer amplifier.
HD-15 Connector 5: Connects to Left Low/Left High amplifier.
HD-15 Connector 6: Connects to Center Low/Center High amplifier.
M. Processor Level
Trimpot adjusts the level of the input signals from the cinema processor.
N. Surround Output Connector
10-pin Phoenix terminal block connects to the power amplifier inputs for Left Surround,
Right Surround, Back Surround Left and Back Surround Right channels.
O. Right-Channel and Subwoofer Output Connector
10-pin Phoenix terminal block connects to the power amplifier
inputs for Right Low, Right High and Subwoofer channels.
P. Left-Channel and Center Output Connector
10-pin Phoenix terminal block connects to the power amplifier
inputs for Left Low/Left High and Center Low/Center High channels.
Q. Bargraph Level
Trimpot adjusts the sensitivity of the front-panel VU Bargraph Meter.
R. Main Input Connector
25-pin D-sub connector connects to the main outputs of the cinema
processor.
S. AC Emergency Power Input Connector
Connects to 12-16VAC, 0.5A source.
T. “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
Left-Surround/Right-Surround inputs to the DSi 8M circuitry.
U. Optional Input Connector
25-pin D-sub connector connects to the EX output of the processor.
