Description

The COLORBOX from Quagliardi Pro Audio is a rugged, high-quality stereo passive DI box designed for seamless integration of unbalanced instrument signals into professional mixers and PA systems. Ideal for keyboards, drum machines, synths, and other stereo sources, the COLORBOX ensures pristine signal integrity while adding the smooth, musical character of custom Quagliardi permalloy-core transformers.

With its passive design, the COLORBOX requires no external power, making it both reliable and convenient for stage and studio use. Each channel includes an individual -20 dB pad, allowing you to accommodate hot input signals without distortion. A ground lift switch helps eliminate hum and buzz caused by ground loops, ensuring a clean, professional output every time.

The DI features dual 1/4" TS inputs with thru connections for flexible routing, along with balanced XLR outputs for direct connection to mixing consoles or recording interfaces. Its lightweight yet durable aluminum chassis is built to withstand the demands of touring, while recessed switches and connectors protect against accidental damage. Whether on stage or in the studio, the COLORBOX Stereo Passive DI Box delivers transparent performance with a touch of analog warmth, making it an essential tool for any serious musician or engineer.
