Crest Audio NC-IPE - TECHNICAL Technical Data

INPUT PROCESSING MODULE
FOR CKS, CKV & CKX SERIES
POWER PROCESSING AMPLIFIERS
NC-IPE
Programmable Input with Priority Page
Product Information
The NC-IPE 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 for level changes
and provision for external switching to a line level page input signal.
A DC voltage ranging from +5 to +24 VDC (at 40mA) will enable a
relay which will switch in the external paging signal. Internal jumpers in
the module can be used to set whether the page input is enabled when
power is applied or enabled when power is removed (allowing the use of
normally open or normally closed switches to control the page function).
Features:
• NexSys-compatible gain control with priority external page
• Programmable precision attenuation when used in conjunction with the hand-held N-Coder or N-Coder/PC software
• Balanced input barrier strip connectors
• 5mm 2-pin Phoenix connector for page-enable
Internal Features:
• Jumper-selectable gain of X20 (26 dB), X40 (32 dB, factory setting), or constant sensitivity for full output at 0dBu (.775V) in.
• Jumper-selectable NO/NC relay

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. A page input barrier
strip, line level feed shall be activated by the page enable relay. This in turn shall be activated
via a contact closure providing +5 to +24 VDC at the page enable connector.

Hi Lo
NexSys Bus
In conjunction with the hand-held N-Coder or N-Coder/PC software, the
NC-IPE can also function as a precision attenuator in NexSys
NexSys controlled 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-IPE 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.)
• Removable gain pot knobs for security
• Simple setup, tamper-proof configuration

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/programmed
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-IPE.
