Palmer PAN 04 – 2-channel passive DI Box for stage, studio and stereo keyboards

If you're looking for a reliable tool to clean up your signal and seamlessly connect instruments to a sound system, this model is designed exactly for that purpose. It’s a compact 2-channel passive DI Box that performs equally well in live and studio environments as well as installations. Thanks to its stereo design, it is perfect for keyboards, electronic instruments, media players, interfaces, and other dual-output devices. Its main function is converting unbalanced signals into balanced ones, helping reduce noise and enabling long-distance signal transmission. In practice, this means a cleaner signal, better connection stability, and peace of mind during live performances.

Product features

The biggest advantage of this design is the combination of simplicity, reliability, and practical usability. You get two independent channels, effectively replacing two single DI boxes in one enclosure. This is extremely convenient when working with stereo instruments or when you want to minimize gear on stage or in your setup. The passive design requires no power supply, so the unit is always ready to use. Additionally, transformer-balanced circuitry ensures stable operation, reduced hum, and resistance to demanding stage conditions.

Reliable connection between instrument and PA system

In everyday use, features that solve real problems matter most. This unit includes an attenuation switch for matching input levels and a ground lift function that helps eliminate hum caused by ground loops. The high maximum input level allows safe handling of stronger signals, while THRU outputs on each channel enable signal routing to amplifiers or additional devices. Instead of complicating your setup, it simplifies it. You can focus on performance, rehearsal, streaming, or recording without worrying about signal integrity.

Another key advantage is the compact and extremely durable steel housing with a powder-coated finish. It withstands transport, frequent cable changes, and tough stage conditions. Its small footprint makes it easy to pack into a gig bag, rack case, or cable box. This is especially important for live performers and mobile setups. Despite its size, it delivers professional functionality without taking up valuable space.

Applications

This DI Box is ideal wherever you need to safely connect line-level or instrument signals to a mixer, stagebox, or PA system. It is perfect for stereo keyboards, synthesizers, samplers, drum machines, media players, and audio interfaces. It works great in live concerts, rehearsal spaces, studios, houses of worship, and mobile event systems. It’s also an excellent choice for engineers who need a versatile stereo DI Box ready for different setups.
