You can set OPTIMOD-PC's audio bandwidth in two places:
(1) in the I/O Mixer's C
tab. (If the EQ tab is not visible, click the AD button on the toolbar.)
OPTIMOD-PC's bandwidth is always the lowest of these settings. The fre-

highest bandwidth available. The installing engineer should set it to be
appropriate for the sample rate of the digital system that OPTIMOD-PC is
driving. For example, if OPTIMOD-PC is driving a system with a 32 kHz
sample rate, set the M
That way, a setting of 20 kHz in the EQ tab will not cause excessive
bandwidth and aliasing because OPTIMOD-PC will automatically override
it with the M
