INPUT PROCESSING MODULE
FOR CKS, CKV & CKX SERIES
POWER PROCESSING AMPLIFIERS
Features:
• Two (2), four-band parametric EQ’s with programmable boost/cut, bandwidth and frequency parameters
• All parameters (including precision attenuation settings) programmable via NexSys , hand-held N-Coder or N-Coder/PC software
• Balanced inputs and loop-thru outputs on barrier strip connectors with .325" (8.3mm) screw center, .270" (6.9mm) lug space
• Removable gain pot knobs for security
Internal Features:
• Jumper-selectable gain of X20 (26 dB), X40 (32 dB, factory setting), or constant sensitivity for full output at 0dBu (.775V) in.
NC-SEQ
Stereo Parametric EQ
Product Information
The NC-SEQ Module fits in the Input Processing bay located on the rear
panel of Crest Audio CKS, CKV & CKX Series Power Processing
amplifiers.
The NC-SEQ is a high quality four-band stereo parametric EQ. Each
band of the equalizer has programmable boost/cut, bandwidth and fre-
quency parameters.
Unbalanced post-EQ loop-thru barrier strip connectors provide conve-
nient outputs to other amplifiers. 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 provided with removable knobs for
extra security. The NC-SEQ is programmable via NexSys
®
, the hand-
held N-Coder or N-Coder/PC software. (NexSys-compatible
Power/Output and Network NC modules are required for NexSys imple-
mentation.)
Architects and Engineers Specifications - NC-SEQ.
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 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.
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 pro-
gramming. 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.
