Description

The Heritage Audio P DI ONE is a single-channel passive DI box designed to deliver uncompromising clarity, tone integrity, and noise-free performance in both studio and live settings. At its heart is the custom-designed HA-DI transformer-a nickel-core component engineered for ultra-transparent signal transfer and shielded in MU-metal to protect against electromagnetic interference. Whether you're connecting a synth, drum machine, sampler, or an active guitar or bass, the P DI ONE ensures your instrument's true character comes through-clean, balanced, and free from unwanted noise.

With its passive design, the P DI ONE requires no power and offers plug-and-play simplicity while effectively eliminating hum and buzz caused by ground loops. A built-in 15dB pad accommodates hotter signal sources or line-level outputs, and a ground lift switch offers additional flexibility in challenging environments. All connections-gold-plated input, thru, and XLR output-are designed for optimal signal path and long-term reliability. The rugged 14-gauge steel chassis and MIL-spec circuit board ensure road-ready durability and quiet operation. Compact, reliable, and sonically invisible, the P DI ONE is the go-to solution for capturing your sound with zero compromise.
