Palmer PAN 01 DI Box Passive

The Palmer PAN 01 is a passive DI box built for the signal-handling demands of real-world venues and studios. Unlike active designs, it relies on transformer-balanced architecture to convert high-impedance instrument or speaker outputs into low-impedance, balanced XLR for mixing consoles and audio interfaces. Palmer's passive topology eliminates the need for phantom power or batteries, making it a transparent, always-ready tool for touring and session work.

Signal handling is the PAN 01's strength. A 10:1 step-down transformer coupled with an attenuable input pad (–30 dB reduction available) allows it to manage both line-level and speaker-level signals—crucial flexibility when dealing with variable output stages. Input impedance sits at 60 kOhm, with a maximum input level of +54 dBu and output capability up to +4 dBu. The parallel 6.3 mm jack THRU output lets you send unbalanced signal downstream while the XLR carries balanced signal to the console. A ground-lift switch addresses hum in problematic cable runs. Sheet-steel powder-coated chassis measures 110 × 73 × 42 mm and weighs 340 g.

Features

• Passive transformer-balanced XLR output; no phantom power required.
• Parallel jack THRU output for daisy-chaining unbalanced signals.
• Attenuable input pad: 0 dB or –30 dB for wide signal range.
• Handles line level (+54 dBu max input) and speaker-level signals.
• Ground-lift switch to eliminate ground-loop hum.
• 60 kOhm input impedance at 60 Hz; 600 Ohm output impedance.
• Frequency response: 20 Hz to 20 kHz across transformer path.
• Compact, powder-coated steel chassis; 340 g weight for portability.
