BLENDING BOTH INPUTS TOGETHER
While the PZ-Pro makes it easy to toggle between
two inputs at the press of a footswitch, you may also
wish to blend both input sources together, allowing
you to combine the warmth and low end from a
microphone with the brightness and clarity from
your pickup system. To combine both input signals,
press the A+B switch on the rear panel of the PZ-
Pro. Once this switch is engaged the A and B LEDs
will both illuminate and the Toggle Footswitch will no
longer have any effect as both inputs will be active
at all times.
Aside from the Toggle Footswitch, when blending both inputs together
with the A+B switch the remaining PZ-Pro features will continue to
function normally: The EQ and Filter sections still allow you to tailor the
sound of each individual input before they are blended, and the FX Loop
and Boost controls can be assigned to affect only Input A, Input B, or
The A+B switch
The 180 switch
With the A+B switch engaged, the PZ-Pro can blend together
two sources, such as a set of pickups and a microphone
both.
When summing two different signals from the same
sound source, it is common for some frequency
cancellation to occur as a result from each signal
arriving at the PZ-Pro at slightly different times. The
Input B 180 switch helps correct for this by reversing
the polarity on Input B, affecting both the XLR Mic
Input and the 1/4" Input on this channel.
There is no right or wrong setting for the 180 switch, so try it in both
the off and on positions while playing your instrument to see which one
sounds best to your ears. If you have a hard time telling the difference,
try playing the lowest note on your instrument, as frequency cancellation
is easiest to hear in the lower register.
