Adding A Stage Amp - Radial Engineering Tonebone PZ Deluxe User Manual

®
ADDING YOUR STAGE AMP
You can now connect your stage amp to the PZ-Deluxe. This separately buffered output is used
to provide you with a personal monitor system that you can control for your on-stage sound.
Turn up the volume and listen. Now, you will have sound coming from both the PA and your
stage amp. For fun, try switching the 180° phase switch at the DI-OUT. This will change the
phase relationship between the PA and your amp which will cause the tone to change. When
sound is coming from two different sources such as a PA and stage amp, some frequencies
will combine together to create peaks while others will cancel out to create dips. This is known
as comb-fi ltering. The peaks can often cause feedback so reversing the polarity (or the phase)
will cause these offending frequencies to cancel which in turn can eliminate feedback. You
can also reverse the phase going to the stage amp to see if this helps. Keep in mind that the
two 180° phase reverse switch are in series.
GROUND LIFT
When connecting the PZ-Deluxe to your amp and the PA at the same time, you can encounter
noise in the form of buzz or hum. This is caused by what is commonly known as a ground
loop. Ground loops occur when the audio ground path and the electrical ground path interact.
Using the LIFT switch to disconnect the ground between the PZ-Deluxe and the PA can often
eliminate this type of noise.
POWER BOOSTER
The PZ-Deluxe is equipped with a BOOST footswitch that lets you increase your output level
for soloing. The boost gain is determined by a recessed BOOST 'set & forget' level control
on the side. Engage the BOOST footswitch (LED on) and use a screwdriver or guitar pick
to adjust the boost level. Once you have found the boost level that works for you, it can be
activated anytime simply by depressing the BOOST footswitch. When you do, the LED will
go on. Hit it again and the boost will turn off.
TUNER & MUTE
The other footswitch on the PZ-Deluxe is a mute. This is designed to turn off all of the outputs
except for the one labelled tuner. This 'always on' output is designed to allow you to monitor
your tuning at all times and by depressing the footswitch, mute the signal going to your amp
and PA should you need to do a quick adjustment.
