Crest Audio NC-IPN - TECHNICAL Technical Data

INPUT PROCESSING MODULE
FOR CKS, CKV & CKX SERIES
POWER PROCESSING AMPLIFIERS
NC-IPN
Programmable Gain Input
Product Information
The NC-IPN Module fits in the Input Processing bay located on the rear
panel of Crest Audio CKS, CKV & CKX Series Power Processing
amplifiers. It includes programmable gain elements and provision for
optional input isolation transformers. In conjunction with NexSys
ware, the hand-held N-Coder or N-Coder/PC software, the NC-IPN can
also function as a precision attenuator in NexSys and non-NexSys con-
trolled applications.
Features:
• NexSys-compatible gain control
• Programmable precision attenuation via NexSys network, N-Coder or N-Coder/PC software.
• Balanced input barrier strip connectors
• 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.

An internal 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 pro-
vided with removable knobs for extra security. The NC-IPN is program-
® soft-
mable via NexSys, the hand-held N-Coder or N-Coder/PC software.
(NexSys-compatible Power/Output and Network NC modules are
required for NexSys implementation.)

An internal input sensitivity/voltage gain jumper shall be provided with selections of 0dBu,
X20 and X40. Programmable gain elements shall be provided that can be controlled/pro-
grammed either by NexSys via an NC-NXS module (if fitted), a hand-held N-Coder or N-
Coder/PC software. The module shall be designated the Crest Audio model NC-IPN.
