Use only with Radial power supply #R800-9407. 2. EFFECTS LOOP (PIEZO CHANNEL): ¼” TRS insert jack allows effect pedals to be placed in the acoustic piezo signal path. (Tip=Send / Ring=Return) 3. BALANCED DI OUT: balanced mic-level XLR output sends acoustic piezo signal to the PA or recording system. 4.
True to the Music PIEZO CHANNEL CONTROL SECTION 12 13 14 15 16 12. ¼” GROUND LIFT: disconnects the ground connection at the ACOUSTIC PIEZO ¼” output to reduce hum and buzz caused by ground loop between amplifiers. 13. XLR GROUND LIFT: disconnects the pin-1 ground connection on the XLR output to reduce hum and buzz caused by ground loops. 14. XLR 180º POLARITY: reverses signal polarity at the XLR output to help with phase and feedback problems. 15.
True to the Music USING THE PZ-DI The Radial PZ-DI is pretty much ‘plug and play’ easy to use. There are only a few little extras that one needs to be aware of to take full advantage of the PZ-DI’s feature set. The easiest way to understand the PZ-DI is to follow the basic block diagram: There are two inputs each of which drives a separate channel: one for the magnetic (electric pickup) and one for the piezo (acoustic pickup).
True to the Music The Magnetic Electric Start by connecting the electric guitar amp using a standard ¼” cable. Turn the amp on, turn up the volume a bit and test to make sure it works by depressing the electric footswitch. The LED on the PZ-DI should illuminate and you should hear sound. To keep the purist happy, the magnetic (electric pickup) signal path has been purposely kept extremely clean.
True to the Music The Built In Direct Box The PZ-DI is equipped with a built-in active Radial DI box that works exclusively with the piezo channel. This DI circuit is similar to the popular Radial J48 in that it is active and able to handle plenty of level without distortion. There are two dedicated slider switches for the direct box: a ground lift that lifts pin-1 at the XLR output connector and a 180º polarity reverse.
True to the Music CONNECTING AND USING EFFECTS PEDALS Using Effect Pedals With The Acoustic Piezo Channel Another cool feature built into the PZ-DI is the effects loop. This is dedicated to the piezo acoustic channel as a means of adding effects to the acoustic signal path. This way, your acoustic pickup can have effects like reverb or a more radical EQ routed to both your on-stage amp and to the PA and monitor systems.
True to the Music FAQ Can I use the PZ-DI with two electric guitars? You could, but you may be better served with the lower priced BigShot i/o. The PZ-DI is not designed to send the two pickup signals to the same amp. So this may not work for your setup. Why does the PZ-DI use a 15V volt supply - not a 9V? Unlike guitar pedals that merely need to control electric guitars, the PZ-DI also must control acoustic signals. These tend to have radical transients with more dynamic range.
