Getting Started Setting Up The Pz-Deluxe - Radial Engineering Tonebone PZ Deluxe User Manual

True to the Music
GETTING STARTED
Set your controls in the start position with all knobs at 12 o'clock except for the level control
which is set to 7 o'clock or minimum. Make sure the BOOST and MUTE footswitches are not
engaged (LEDs off). Set the high pass fi lter to the up position (fl at) and the two 180° phase
switches to the down (in phase) position.
Test at a low level
Turn on your PA and bring up the volume. Always test at low levels as this will reduce pos-
sibility of equipment damage should a problem occur. Slowly increase the LEVEL control on
the PZ-Deluxe until you can hear sound. If you hear hum or buzz try toggling the ground LIFT
switch. If the sound is distorted ensure the PZB switch is in the correct position for the type
of pickup you are connecting.
The 3-band semi-parametric EQ
The PZ-Deluxe is equipped with a very powerful 3-band EQ that is used to shape your tone
and eliminate feedback. It is very powerful therefore small changes can have a dramatic effect.
Start by setting the controls to the 12 o'clock position. The low and high frequency controls
are straight ahead while the MID/FREQ controls require some explanation. This type of EQ
is known as a semi-parametric whereby it has a fi xed-Q, a sweepable center-frequency and
variable cut/boost gain control. To hear the effect, turn the MID control to 3 o'clock and then
rotate the FREQ control to hear what is happening. This will accentuate frequencies as you
sweep the control, allowing you to fi nd a frequency that may sound harsh to your ears. Once
you have found the offending frequency, roll back the MID control to around 11 o'clock and
listen. The more you experiment the more control you will have over your sound.
The low-cut fi lter
Another handy feature is the low-cut or high pass fi lter. A high pass fi lter does exactly that, it
cuts the lows to allow the high frequencies to pass. This three position switch lets you reduce
unwanted resonance by simply moving the switch from the fl at position downward. The middle
position has a moderate cut while the bottom position cuts more bass. As a general rule, the
smaller the instrument, the more cut you will apply. Cutting the bass helps eliminate resonant
feedback that can cause the top or the instrument to vibrate. Smaller instruments vibrate at a
higher frequency, thus are often better served with a higher cut-off point.
