INPUT PROCESSING MODULE

FOR CKS, CKV & CKX SERIES

POWER PROCESSING AMPLIFIERS

NC-MCO

Product Information

The NC-MCO Module fits in the Input Processing bay located on the

rear panel of Crest Audio CKS, CKV & CKX Series Power Processing

amplifiers. It is an extremely high quality, fourth-order, two-way elec-

tronic mono crossover that feeds the HF output to channel A of the

amplifier and the LF output to channel B. The HF and LF output levels

and crossover frequencies are individually programmable. Unbalanced

loop-thru barrier strip connectors provide convenient outputs to other

amplifiers.

Features:

• NexSys compatible, programmable two-way, 24dB per octave electronic crossover

• Independent two-way, 4th-order, Linkwitz-Riley filters

• Removable gain pot knobs for security

• All parameters (including precision attenuation settings) programmable via NexSys , hand-held N-Coder or N-Coder/PC software

• Balanced input on barrier strip connector with .325" (8.3mm) screw center, .270" (6.9mm) lug space

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 assignment of high-pass or low-pass output for each amplifier channel

Architects and Engineers Specifications - NC-MCO.

The module shall plug into Crest Audio CKS or CKV Power Processing amplifiers in the

Input Processing bay. The module shall be NexSys-compatible. The module shall provide a

two-way, 24 dB per octave electronic crossover with programmable HF and LF output lev-

els, HF and LF crossover frequencies, overall output level and HF/LF polarity inversion.

The module shall be controlled/programmed either by NexSys via an NC-NXS module (if

fitted), a hand-held N-Coder or N-Coder/PC software.

Data

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-MCO is pro-

grammable via NexSys

ware. (NexSys-compatible Power/Output and Network NC modules are

required for NexSys implementation.)

• Loop-thru HF and LF outputs

• Simple setup, tamper-proof configuration

Signal

All programmed settings shall be stored in non-volatile EEPROM memory. A barrier strip

input connector shall feed one electronically balanced input. Two removable-knob gain pots

shall be provided that control the level of each amplifier channel independent of program-

ming. High pass and low pass, loop-thru outputs shall be available on barrier strip connec-

tors. An internal input sensitivity/voltage gain jumper shall be provided with selections of

0dBu, X20 and X40. The module shall be designated the Crest Audio model NC-MCO.
