The following NC-MCO parameters can be con-
trolled by the hand-held N-Coder, N-Coder/PC
software, or via NexSys software.
N-Coder:
Channel attenuation, phase reverse, trim and fre-
quency for high & low pass
N-Coder/PC software:
Channel attenuation, phase reverse, muting, trim
and frequency for high & low pass
NexSys computer control:
Channel attenuation, phase reverse, solo, muting,
input and output VU metering, trim and frequency
for high & low pass
