Product Information
The CC-IPB Module fits in the Input Processing bay located on the rear
panel of Crest Audio CKS, CKV & CKX Series Power Processing
amplifiers. It is fitted standard to all models. CC-IPB provides balanced
inputs to the two amplifier channels.
Features
• Balanced input on barrier strip connector with .325" (8.3mm) screw center, .270" (6.9mm) lug space
• Removable gain pot knobs for security
• Input isolation transformers optional
Internal Features
• Jumper-selectable gain of X20 (26 dB), X40 (32 dB, factory setting), or constant sensitivity for full output at 0dBu (.775V) in.
CC-IPB connections
An internal three-position jumper selects between gains of X20 (26 dB),
X40 (32 dB), or constant sensitivity for full output at 0dBu (.775V) in.
The standard factory setting is for X40 (32dB). Individual channel attenuators are provided with removable knobs for extra security.
®
CC-IPB is not programmable or NexSys
controllable.
