NC-AES - Crest Audio

INPUT PROCESSING MODULE
FOR CKS, CKV & CKX SERIES
POWER PROCESSING AMPLIFIERS
NC-AES AES/EBU Digital Input
Product Information
The NC-AES Module fits in the Input Processing bay located on the rear
panel of Crest Audio CKS, CKV & CKX Series Power Processing
amplifiers. It provides digital input via an AES/EBU digital port.
Two balanced analog outputs are provided to daisy chain to additional
amp channels requiring the same analog signal.
Features:
• Attenuation programmed by NexSys, N-Coder/PC software, or hand-held N-Coder.
• Balanced post-processing loop-thru outputs on barrier strip connectors
• AES/EBU digital input
• Simple setup, tamper-proof configuration
• Amp channel gain pot knobs removable for security

Individual channel attenuators are provided with removable knobs for
extra security. The NC-AES is programmable via NexSys ® , the handheld
N-Coder or N-Coder/PC software. (NexSys-compatible
Power/Output and Network NC modules are required for NexSys implementation.)
