Upon unpacking, inspect the amplifier. If you find any damage, notify your supplier immediate-
ly. Only the consignee may institute a claim with the carrier for damage incurred during ship-
ping. Be sure to save the carton and all packing materials. Should you ever need to ship the
unit for any reason, use only the original factory packing. If the shipping carton is unavailable,
contact Crest to obtain a replacement.
Crest Audio CKi amplifiers are configured to a standard set-up at the factory.They are func-
tional and ready to use 'out of the box. ' All controls and input/output connections are clearly
labeled. Units are shipped standard with a blank panel in the module bay.
To set the amplifier up for basic usage:
1. Mount the amplifier in a rack, remembering to allow for adequate access and cool-
ing space.
See - Cooling Requirements below for more information.
2.Make input connections via the rear-panel Phoenix connector inputs.Make the con-
nections to both inputs (Ch A and Ch B) for stereo operation, or connect to Ch A
only for parallel or bridged mono configuration.
See - Chapter 4 Modes for more information.
3. Connect speakers to the output barrier strip. Be sure to make the correct output
connections for stereo, parallel or bridged mono configuration.
See - Chapter 5 Operation for more information.
4. Make power connections, allowing for proper current draw.
See - Chapter 5 Operation for more information on power considerations.
5.Turn the front panel three-position AC switch to 'on', and bring up the rear panel
gain attenuators to the desired level.
CKi Power Processing amplifiers are 2, 3 & 4-rack space units of 17 1/8" (437mm)
depth that mount in a standard 19-inch rack. On 2 &3 rack space units, four front
panel-mounting holes are provided. 4-rack space units have eight front panel-mount-
ing holes.
Rear mounting ears are also provided on all amplifiers for additional support, which
is essential in non-permanent installations like mobile or touring sound systems, and
recommended for permanent installations. (Distance from the back of the front rack
ear to the center of the rear mounting ear holes is 16 5/8" / 422mm) Because of the
cables and connectors on the rear panel, a right-angle or offset screwdriver or hex
key will make it easier to fasten the rear mounting ears to the rails
