The following NC-DSP-A parameters can be con-
trolled by N-Coder/PC software or via NexSys
software.
N-Coder/PC software:
Channel A & B attenuation, phase reverse, muting,
all DSP functions*.
NexSys computer control:
Channel A & B attenuation, phase reverse, solo,
muting, input and output VU metering; all DSP
functions*.
*DSP Programs: Stereo BP, HP and LP
crossovers, mono BP/BP, BP/HP, LP/BP, and
LP/HP crossovers, dual mono 5-band EQ
*DSP Algorithms: Mixer, shelf, 4 and 5-band
parametric EQ, long delay, bandpass crossover, 4-
band parametric post EQ, short delay, limiter, gain
