The module shall plug into Crest Audio CKS or CKV Power Processing amplifiers in the Input Processing bay. The module shall include a fully programmable four band parametric stereo equalizer with center frequency, bandwidth and boost/cut parameters. 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. 9876 5432 E DCBA 9876 Lo + ­ + ­ Model NC-SEQ Input Signal B All programmed settings shall be stored in non-volatile EEPROM memory. A barrier strip input connector shall feed two electronically balanced inputs. Two removable-knob gain pots shall be provided that control the level of each amplifier channel independent of programming. Post-EQ 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-SEQ.
