DSi-8M

he Crown® DSi-8M is a projection booth Tmonitor designed to work with bi-ampli- fied cinema systems using the Crown DSi

Series amplifiers.

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.

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.

Specifications

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.

Using VGA cables, the HD-15 connectors can be connected to Crown DSi power amplifier HD-15 connectors as described below.

HD-15 Connector 1: For cinema I/O compatibil- ity. Connects to Ls/Rs amplifier.

HD-15 Connector 2: Connects to Bsl/Bsr amplifier.

HD-15 Connector 3: Connects to Rl/Rh ampli- fier.

Input Impedance (Processor Inputs): 10 k ohms.

Input Impedance (Power Amplifiers 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/Amplifier Selector Switch and LEDs: Pushbutton switch with corresponding LEDs selects inputs from cinema procesor or power amplfiers 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

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 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.

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.

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:

1.Connect DSi 8M outputs to DSi amplifier inputs.

2.Connect DSi amplifier outputs to DSi 8M inputs for monitoring.

HD-15 Connector 4: Connects to Sw amplifier.

HD-15 Connector 5: Connects to Ll/Lh ampli- fier.

HD-15 Connector 6: Connects to Cl/Ch ampli- fier.

Optional Input Connector: 25-pinD-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.
