- Page 3 This manual has been written to provide you with a full understanding of how to use the PZ-DI and get the most out of it. Please take a few minutes to read it all the way through. You will find that there are several innovative features built-in that can greatly enhance your enjoyment and the outcome.
- Page 4 INPUT PANEL OUTPUT PANEL INPUT: ¼” hi-Z input used to connect the instrument to the PZ-DI. NO SLIP PAD: Provides electrical and mechanical isolation while keeping the PZ-DI from sliding around on busy stages. THRU: ¼” throughput used to feed an on-stage instrument amplifier.
- Page 5 One of the coolest features on the PZ-DI is the load adjustment switch. This works with the PAD to let you interface a wide variety of pickups or sources to both maximize the frequency response and minimize distortion. There are three settings to choose from.
- Page 6 You should also test at low volumes before turning up. The PZ-DI does not require a battery or power supply to make it work. It uses 48V phantom from the mixing console. All you do is plug it in, turn the phantom power on at the...

Page 7: Making Connections
Connect the source instrument to the input using a standard ¼” instrument cable, set the appropriate load and connect the XLR output to your mixer using a standard mic cable. The PZ-DI will convert the high-impedance unbalanced signal to a balanced low impedance signal that will properly interface with the audio system. This will enable you to run long balanced cables without noise or signal loss. - Page 8 Thru on swITCh The PZ-DI features a side access buffer ON ‘set & forget’ switch that allows the thru-put connector to be used two ways.
- Page 9 The -15db Pad As previously mentioned, the -15db PAD is used to reduce the PZ-DI’s input sensitivity. This lowers the signal level while also lowering the impedance to reduce susceptibility to noise. Most instruments do not produce enough output to overload the PZ-DI.
- Page 10 The ground lIfT swITCh One of the unique features that is built into the PZ-DI is the power system. This converts 48V phantom power using a switching supply that increases the signal handling capability while enabling the ground lift switch to be engaged without disconnecting the 48V phantom power.
