Description

This compact active inline DI delivers clean, transparent instrument signals through an Ultra-HiZ input and dedicated Class-A output buffer. Its 10 MΩ input impedance makes it suitable for electric guitars, basses, piezo pickups, keyboards, synthesizers, drum machines and laptops.

The matte-black all-metal housing includes a lockable 1/4-inch input, gold-plated XLR output and recessed switches for attenuation and three-stage ground lift control. It connects directly to a phantom-powered XLR input, while the included screwdriver makes switch adjustments easy.

Features

Ultra-HiZ Input
The high input impedance places minimal load on connected instruments, helping preserve their natural sound and supporting low-output passive pickups.

High Input Headroom
The active circuitry accommodates high-output instruments and line-level sources without sacrificing signal quality.

Switchable Attenuation
A recessed three-position pad reduces the input signal when working with active pickups, keyboards, drum machines and other powerful sources.

Advanced Ground Lift
Off, On and On+ settings help address ground-loop hum, buzz, hiss and radio-frequency interference in a range of recording and live setups.

Lockable Input
The locking input jack helps prevent accidental cable disconnection and can be disengaged when a conventional connection is preferred.

Class-A Output Buffer
The dedicated output stage supplies a clean, consistent signal across different cable lengths and load impedances.

Direct XLR Connection
The integrated male XLR connector plugs directly into compatible interfaces, mixers and stage boxes without an additional output cable.

Roadworthy Construction
A slim all-metal housing, gold-plated XLR connector and matte-black finish provide durability in a pocket-sized design.
