Marketing Information |
The CDi Series of Crown® amplifi ers are
professional tools designed and built for installed sound applications.
The series includes four models which are identical except for output
power: CDi 1000, CDi 2000, CDi 4000 and CDi 6000. 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 processing. Other features
include a switch-mode universal power supply, useful function
indicators, proportional-speed fanassisted cooling, removable
Phoenix-style inputs, barrier strip outputs for low-Z or 70V/100V/140V
loads, short-circuit protection and more. |
