[. . . ] INPUT PROCESSING MODULE FOR CKS, CKV & CKX SERIES POWER PROCESSING AMPLIFIERS Power Processing Modules NC-IPE Product Information Programmable Input with Priority Page 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® and nonNexSys 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. [. . . ] 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 · Removable gain pot knobs for security · 5mm 2-pin Phoenix connector for page-enable · 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. · Jumper-selectable NO/NC relay NC-IPE connections N-Coder OR PC Lap-Top running N-Coder/PC software Crest Audio Revision 1. 03E Page Signal Designed & manufactured in the USA by: quential urn-On CLASS 2 WIRING MAY BE USED Crest Audio Inc.

The module shall plug into Crest Audio CKS or CKV Power Processing amplifiers in the Input Processing bay. Barrier strip input connections 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. 9876 9876 Lo + ­ + ­ Model NC-IPE 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.
