Compact & Rugged Construction

The ultra-compact DI 22P is built to handle the rigours of life on the road via a thick and rugged aluminium extrusion that protects the electronics. The enclosure’s roadworthiness is further enhanced through the implementation of sturdy rubber corner bumpers.

High Headroom Design

A custom instrumentation-grade input circuit was designed for the DI 20P using advanced analogue design techniques to create the ideal input impedance match. This innovative approach provides an ultra low noise, low harmonic and phase distortion input stage with a ruler-flat frequency response that ranges from 20 Hz to 30 kHz (±1 dB).

Connectivity & More

DI 22P PRO DI AV 2 Inputs are: 2 x 1/4" TS; 2 x RCA ; and 1 x 1/8" TRS connectors, which can accommodate virtually any type of signal – for the utmost in versatility. The genuine Neutrik* Output XLR jacks send balanced versions of the input signals to your mixing board or other processing device.

Input Pad, Earth Lift Switch & More

A -15 dB input Pad enables the DI 22P to easily accept a wide range of input signals including guitar, line and speaker levels (up to 30 dBu). The onboard Earth Lift switches separate the input and output grounds, eliminating earth loops between equipment on different mains electricity supplies. DI 22P’s fully transformer-isolated design further ensures pristine performance – even in large-scale production environments.


The DI 22P PRO DI AV 2 provides maximum versatility with frequency response from 20 Hz to 30 kHz (±1 dB), MIDAS custom-design transformers for the ultimate signal integrity, and much more – all in a road-ready enclosure that stands ready for your input.
