PDI-2
Passive Dual-Channel Di Box
The PDI-2 is a dual-channel passive DI box designed for instruments, keyboards, electronic instruments, and stereo audio sources. Built with a transformer-based passive circuit, it converts unbalanced signals into balanced XLR outputs for connection to mixers, audio interfaces, and professional sound systems. With 2 × 1/4" inputs, 2 × 1/4" Thru connections, and 2 × XLR outputs, the PDI-2 supports practical signal routing for stage and studio setups. It requires no battery, phantom power, or external power supply, and features a 0 dB / -15 dB input pad and Ground Lift switch for flexible operation.
