 DSi-8M is a projection booth 
monitor designed to work with bi-ampli-
fi ed cinema systems using the Crown DSi 
Series amplifi ers. 
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 
amplifi er’s outputs: L,C, R, Ls, Rs, Bsl, Bsr, 
and Sub in any combination.
Input levels from the processor and power am-
plifi er can be adjusted independently. There are 
no huge level jumps when switching between 
processor and power amplifi ers.
The bargraph display can be calibrated to the 
reference level for your theater. The projection-
ist can see auditorium levels instantly. 
Your investment in a DSi-Series product is 
backed by Crown’s Three-Year, No-Fault, Fully 
Transferable Warranty.

Specifi cations
Input Impedance (Processor Inputs): 10 k 
ohms.
Input Impedance (Power Amplifi ers Inputs): 
> 50 k ohms.
Power Requirements:  100-240V    , 50-60 Hz, 
32 watts.
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.
Volume Control: Rotary potentiometer with 
knob controls the volume of the internal or 
external speaker. Has no effect on the VU 
Bargraph Meter display.
Processor/Amplifi er Selector Switch and 
LEDs:
 Pushbutton switch with corresponding 
LEDs selects inputs from cinema procesor or 
power amplfi ers for monitoring.
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.
Test Jack: 1/4" phone jack lets the user moni-
tor 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.
Internal Speaker: For convenenient monitor-
ing at the monitor panel.
Power Switch and Power LED: Rocker switch 
turns power on or off. LED illuminates when 
power is on.
Rear Panel Controls and Connectors
IEC AC Power Receptacle: Connects to an IEC 
AC power cord.
Input Connector 1: 10-pin Phoenix terminal 
block connects to the power amplifi er 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 amplifi ers that do not 
include HD-15 connector options.
Input Connector 2: 10-pin Phoenix terminal 
block connects to the power amplifi er 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 amplifi ers that do not include HD-15 
connector options.
Amplifi er Level Control: Trimpot adjusts 
the level of the input signals from the power 
amplifi ers.
Processor Level: Trimpot adjusts the level of 
the input signals from the processor.
Outputs to Power Amplifi er Inputs: The six 
HD-15 connectors in this section connect to 
DSi amplifi ers for both input and output sig-
nals. The HD-15 connectors have two func-
tions:
1. Connect DSi 8M outputs to DSi amplifi er 
inputs.
2. Connect DSi amplifi er outputs to DSi 8M 
inputs for monitoring.
Using VGA cables, the HD-15 connectors can 
be connected to Crown DSi power amplifi er 
HD-15 connectors as described below.
HD-15 Connector 1: For cinema I/O compatibil-
ity. Connects to Ls/Rs amplifi er.
HD-15 Connector 2:  Connects to Bsl/Bsr 
amplifi er.
HD-15 Connector 3:  Connects to Rl/Rh ampli-
fi er.
HD-15 Connector 4:  Connects to Sw amplifi er.
HD-15 Connector 5:  Connects to Ll/Lh ampli-
fi er.
HD-15 Connector 6:  Connects to Cl/Ch ampli-
fi er.
Optional Input Connector: 25-pin D-sub con-
nector connects to the EX output of the proces-
sor.
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.
