Crown cdi 1000 Manual Suplementario

he CDi Series of Crown

®

 amplifi ers are 

   professional tools designed and built 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 amplifi ers feature an intuitive front-
panel LCD screen to guide installers through 
their confi gurations. CDi amplifi ers also offer 
onboard DSP for loudspeaker signal process-
ing. Other features include a switch-mode 
universal power supply, useful function indica-
tors, proportional-speed fan-assisted cooling, 
removable Phoenix-style inputs, barrier strip 
outputs for low-Z or 70V/100V/140V loads, 
short-circuit protection and more.

Your investment in a CDi-Series amplifi er is 
backed by Crown’s Three-Year, No-Fault, Fully 
Transferable Warranty.

adjustable Q, ±15 dB boost/cut. Also adjust-
able 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.
