–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.

Power Indicator: Blue LED illuminates when the ampliﬁer has been turned on and has power.

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.

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.

Input Impedance (nominal): 20 k ohms, balanced;10 k ohms, unbalanced.

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 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.

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.

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.

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

The chassis shall be steel. Cooling shall be by a proportional speed fan with front-to-rear airﬂow.

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.
