Know before you buy
Active circuitry is designed to preserve the signal integrity of high-impedance instruments, such as acoustic guitars with passive pickups. It ensures your signal remains clear and strong, even when running long cables to a mixing console.
No, the PZ-DI is powered entirely by 48V phantom power provided by your mixing console or audio interface. This eliminates the need for batteries or external power adapters, keeping your setup clean.
Yes, the 1/4 inch Thru output allows you to send your instrument signal to an on-stage amplifier while simultaneously sending a balanced signal to the house PA system via the XLR output.
The PZ-DI is a mono device. If you need to process a stereo signal, you would require two units to maintain the stereo image.
The unit features a heavy-duty steel housing designed to withstand the rigors of professional touring and frequent stage setups. It is built to protect the internal components from accidental drops and impacts.
