Features:
• NexSys-compatible gain control
• Programmable precision attenuation via NexSys network, N-Coder or N-Coder/PC software.
• Balanced input barrier strip connectors • Removable gain pot knobs for security
• Input isolation transformers optional • Simple setup, tamper-proof configuration
Internal Features:
• Jumper-selectable gain of X20 (26 dB), X40 (32 dB, factory setting), or constant sensitivity for full output at 0dBu (.775V) in.
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®soft-
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.
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-
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.)
Architects and Engineers Specifications - NC-IPN.
The module shall plug into Crest Audio CKS or CKV Power Processing amplifiers in the
Input Processing bay. The module shall be NexSys-compatible. Barrier strip input connec-
tions shall be provided which feed two electronically balanced inputs. Two removable-knob
gain pots shall be provided that control the level of each input.
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.
