The module shall plug into Crest Audio CKS or CKV Power Processing amplifiers in the Input Processing bay. The module shall provide a two-way, 24 dB per octave electronic crossover with programmable HF and LF output levels, 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. A 987 A 6 987 + ­ Model NC-MCO Input 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 programming. High pass and low pass, loop-thru outputs shall be available on barrier strip connectors. 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.
