® True to the Music OVERVIEW The Radial PZ-Deluxe is an instrument Preamp. It has been optimized to deliver the pure sound of your instrument no matter what kind of pickup you have. And just like a high quality mic preamplifier, it is designed to do so without introducing noise or artefact.
® True to the Music FEATURE SET 1 2 3 4 5 11 6 10 7 9 8 1. POWER SUPPLY: Connection for the included 15V (400mA) external power supply. 2. DI OUT: Built-in Radial direct box sends balanced mic-level output to the PA system. This allows long runs without adding noise. 3. THREE BAND EQ: Semi-parametric equalizer with separate high and low shelving with a variable mid-frequency for optimal tone shaping. 4.
® True to the Music FEATURE SET 12 9. 13 14 15 MUTE: Footswitch mutes the ¼” stage amp OUTPUT and LOW-Z DI OUT to allow silent on-stage tuning and instrument changes. 10. AMP OUT: Separate ¼” guitar amp output is used to feed the artist’s on-stage amplifier or in-ear monitoring system. 11. TUNER OUT: Separately buffered tuner output is always on to allow on the fly adjustments. 12. LIFT: Lifts pin-1 (ground) on the XLR output to help eliminate hum and buzz caused by ground loops. 13.
® True to the Music MAKING CONNECTIONS Before making any connections, always ensure your audio system is either turned down or turned off in order to protect more sensitive components from damage due to plug-in transients. There is no power switch on the PZ-Deluxe. You simply connect the included 15VDC power supply and it automatically turns on.
® 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 filter to the up position (flat) and the two 180° phase switches to the down (in phase) position. LOW FREQ HIGH 180º 180º LO-CUT LOW-Z DI OUT AMP FILTER MID LIFT LEVEL Test at a low level Turn on your PA and bring up the volume.
® True to the Music 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.
® True to the Music ADDING EFFECTS When incorporating high-Z effect pedals you can either place them before or after the PZDeluxe. The major difference is how the XLR DI-OUT will be affected. For example, if you place effect pedals between the PZ-Deluxe ¼” OUTPUT and your stage amp the DI-OUT will not be affected. Only the clean instrument signal will be sent to the PA. This is a good setup for larger stages and halls.
