SPECIFICATIONS
Performance
Input Impedance (processor inputs): 10 kilohms.
Input Impedance (power amplifier inputs): > 50
kilohms.
Power Requirements: 100-240VAC, 50-60 Hz,
32 watts.
Front Panel Controls and Indicators
Channel Select Buttons and LEDs: Eight push-
button 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.
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/Amplifier Selector Switch and LEDs:
Push-button switch with corresponding LEDs
selects inputs from cinema processor or power
amplifiers for monitoring.
VU Bargraph Meter: 12-segment meter displays
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.
T he Crown DSi-8M is a projection booth monitor designed to work with bi-amplifi 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 moni-
tor 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 amplifi er can be adjusted indepen-
dently. 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 projectionist
can see auditorium levels instantly.
Test Jack: 1/4-inch phone jack lets the user moni-
tor the audio output of the DSi-8M. Inserting a
mono or stereo 1/4-inch phone plug here disables
the internal speaker and routes the audio output to
the Test Jack.
Internal Speaker: For convenient monitoring at the
monitor panel.
Power Switch and Power LED: Rocker switch
turns power on or off. LED illuminates when power
is on.
Back Panel Controls and Connectors
IEC AC Power Receptacle: Connects to an IEC AC
power cord.
Amplifier Outputs Connector 1: 10-pin removable
terminal block connects to the power amplifier
speaker outputs for the Ls, Rs, Bsl, Bsr and Sw
channels.
Amplifier Outputs Connector 2: 10-pin removable
terminal block connects to the power amplifier
speaker output for the Lh, Ll, Ch, Cl, Rh and Rl
channels.
Amplifier Level Control: Trim pot adjusts the level
of the input signals from the power amplifiers.
Processor Level: Trim pot adjusts the level of the
input signals from the processor.
HD-15 Connector 1: For cinema I/O compatibility.
Connects to Ls/Rs amplifier.
HD-15 Connector 2: Connects to Bsl/Bsr amplifier.
HD-15 Connector 3: Connects to Rl/Rh amplifier.
HD-15 Connector 4: Connects to Sw amplifier.
HD-15 Connector 5: Connects to Ll/Lh amplifier.
HD-15 Connector 6: Connects to Cl/Ch amplifier.
Optional Input Connector: 25-pin D-sub connector
connects to the EX output of the processor.
Bargraph Level: Trim pot 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.
