DSi 2000  
Architectural & Engineering Specifications  
DSi 2000  
AC Line Voltage and Frequency Configurations Available: 100V, 120V, 220-240V,  
50/60 Hz.  
AC Line Current: 11.93A.  
At Idle: Draws no more than 45 watts.  
Operating Temperature: 0° C to 40° C at 95% relative humidity (non-condens-  
ing).  
The Crown® DSi 2000 power amplifier shall be a solid-state two-channel model  
with a switch-mode universal power supply. A rear-panel HD-15 connector shall  
provide input/output connectivity between the DSi amplifier and the DSi-8M  
System Monitor. The DSi 2000 shall be THX® approved.  
The DSP section shall have the following specifications:  
Input EQ: 6 parametric filters per channel with adjustable Q, 15 dB boost/cut.  
Also adjustable high and low shelving filters. This 8-filter EQ section can be  
bypassed.  
The outputs shall be usable as stereo or bridged-mono modes of operation.  
The bridged-mono mode shall bridge the outputs to provide increased output  
voltage.  
Front panel controls and indicators shall include the following:  
Level: Detented rotary level control, one per channel.  
Power Switch: On/off switch applies AC power to the amplifier.  
Sel/Prev/Next Buttons: Three buttons near the LCD screen shall be used to  
access menu items and front panel lockout.  
LCD Screen: Backlit liquid crystal display shows speaker presets and signal  
processing.  
Crossover Filters: Highpass and lowpass per channel. Butterworth 6/12/18/24  
dB per octave, Linkwitz-Riley 24/48 dB per octave. Also includes 15 dB band-  
pass gain and polarity control.  
Output EQ: 8 parametric filters per channel with adjustable Q, 15 dB boost/cut.  
This 8-filter EQ section can NOT be bypassed. Filters are enabled individually.  
Signal Indicator: Green LED, one per channel, illuminates when a very low-level  
signal is present at input.  
–10 Indicator: Green LED flashes when output signal exceeds –10 dB below  
clip.  
Output Limiter: Prevents clipping and protects loudspeakers. Choice of –3, –6,  
or –12 dB threshold per channel.  
Delay: Up to 50 msec total delay per channel.  
–20 Indicator: Green LED flashes when output signal level exceeds –20 dB  
below clip.  
Ready Indicator: Green LED, one per channel, illuminates when the amplifier is  
ready to produce audio.  
Clip Indicator: Red LED, one per channel, turns on at the threshold of audible  
distortion.  
Temp Indicator: Red LED, one per channel, illuminates under excessive tem-  
perature conditions.  
Presets: 20 presets. One is “DSP OFF.” Fifteen are factory-set for JBL Cinema  
systems. Four are user-definable.  
Protection shall include the following:  
DSi-Series amplifiers shall be protected against shorted, open or mismatched  
loads; overloaded power supplies; excessive temperature; chain destruction  
phenomena; excessive output current, and input overload damage. They also  
protect loudspeakers from input/output DC, large or dangerous DC offsets and  
turn-on/turn-off transients  
Power Indicator: Blue LED illuminates when the amplifier has been turned on  
and has power.  
The chassis shall be steel. Cooling shall be by a proportional speed fan with  
front-to-rear airflow.  
Rear panel controls and connectors shall include the following:  
AC Line Connector: NEMA 5-15P (15A).  
Input Connector: Two 3-pin removable Phoenix-type connectors each accept a  
balanced line-level input signal.  
Output Connectors: 4-position barrier strip with connectors for dual louspeak-  
ers or bridge-mono loudspeaker.  
Dimensions shall be EIA Standard 19-in. rack mount width (EIA RS-310-B), 3.5  
in. (8.9 cm) high and 12.25 in. (31.11 cm) deep behind mounting surface.  
Net weight shall be 19 lb (8.6 kg). Shipping weight shall be 22 lb (10.0 kg)  
The amplifier shall be designated the Crown DSi 2000.  
HiQnet USB Connector: Type B, connects to a HiQnet network.  
HD-15 Connector: For cinema I/O compatibility with DSi-8M System Monitor.  
The amplifier shall have the following specifications:  
Output Power: 2 ohm Stereo (per channel): 1,000W with 1% THD, 4 ohm  
Stereo (per channel): 800W with 0.5% THD, 8 ohm Stereo (per channel) 475W  
with 0.5% THD, 4 ohm Bridge-Mono: 2,000W with 1% THD, 8 ohm Bridge-  
Mono: 1,600W with 0.5% THD.  
Voltage Gain at 1kHz: 32.9 dB.  
Frequency Response: +0/–1 dB from 20 Hz to 20 kHz at 1 watt into 4 ohms.  
Load Impedance: Safe with all types of loads. Rated for 2 to 8 ohms in Stereo  
mode, 4 to 16 ohms in Bridge-Mono mode.  
Sensitivity at 8 ohm rated output: 1.4V.  
Sensitivity at 4 ohm rated output: 1.2V.  
Sensitivity at 2 ohm rated output: 1.0V.  
Signal to Noise Ratio (below rated 8-ohm power at 1 kHz): 105 dB  
(A weighted).  
Damping Factor: Better than 500 from 20 Hz to 500 Hz.  
Crosstalk: > 70 dB below rated power, 20 Hz to 1 kHz, A-weighted.  
Input Stage: Input is electronically balanced and employs precision 1% resis-  
tors.
