DSP Section
Input EQ: 6 parametric fi lters per channel with
adjustable Q, ±15 dB boost/cut. Also adjustable
high and low shelving fi lters. This 8-fi lter EQ
section can be bypassed.
Crossover Filters: Highpass and lowpass per
channel. Butterworth 6/12/18/24 dB per octave
and Linkwitz-Riley 24/48 dB per octave. Also
includes ±15 dB bandpass gain and polarity
control.
Output EQ: 8 parametric fi lters per channel with
adjustable Q, ±15 dB boost/cut. This 8-fi lter EQ
section can NOT be bypassed. Filters are enabled
individually.
Delay: Up to 50 msec total delay per channel.
Output Limiter: Prevents clipping and protects
loudspeakers. Choice of –3, –6, or –12 dB
threshold per channel.
Presets: 20 presets. 19 are user-defi nable.
Front Panel Controls and Indicators
Level: Detented rotary level control, one per chan-
nel.
Power Switch: On/off switch applies AC power to
the amplifier.
Sel/Prev/Next Buttons: Three buttons near the
LCD screen are used to access menu items and
front panel lockout.
LCD Screen: Backlit liquid crystal display shows
speaker presets and signal processing.
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.
–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, illumi-
nates under excessive temperature conditions.
Power Indicator: Blue LED illuminates when the
amplifier has been turned on and has power.
Rear Panel Controls and Connectors
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 loudspeakers or bridge-mono
loudspeaker. Dual connectors work with 2-8 ohm
or 70V loads. Bridge-mono connectors work with
4-8 ohm or 140V loads.
HiQnet USB Connector: Type B, connects to a
USB port on a PC.
Protection
CDi-Series amplifiers are 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 off-
sets and turn-on/turn-off transients
Construction
Chassis: Steel.
Cooling: Proportional speed fan with front-to-rear
airflow.
Dimensions: EIA Standard 19-in. (48.3-cm) 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: 19 lb (8.6 kg).
Shipping Weight: 22 lb (10.0 kg).
Regulatory Certifications
Note: All measurements apply to all models of CDi
Series amplifiers in stereo mode with 8-ohm loads and
an input sensitivity of 26 dB gain, 1 kHz at rated power
unless other otherwise specified. Specifications for
units supplied outside the U.S.A. may vary slightly at
different AC voltages and frequencies.
T he CDi Series of Crown ® amplifiers are designed for installed sound applications. The series includes
three models which are identical except for output power: CDi 1000, CDi 2000 and CDi 4000. All are
rugged and lightweight, and offer unmatched value in their class. CDi-Series amplifiers feature an LCD
screen with DSP speaker presets. Other features include a switch-mode universal power supply, useful
function indicators, proportional-speed fan-assisted cooling, removable Phoenix-style inputs, barrier
strip outputs for low-Z or 70V/140V loads, short-circuit protection and more.
