I UT-106

DSP UNIT

The UT-106 provides AF DSP functions such as noise
reduction and auto notch.
Up to 2 DSP units can be installed for simultaneous
DSP operation for both MAIN and SUB bands.
When only 1 DSP unit is installed, DSP functions can
be operated in either the MAIN or SUB band,
whichever is being accessed.
NOTE: The insulating soft case is not used with the
IC-910H.
RECOMMENDATION:
When installing only 1 DSP unit, you can install into
either front or rear panel side. However, installing a
DSP unit into the front panel side may be easier and
also safer.
