sE Electronics DM3 (Black) Active DI Box

sE Electronics DM3 (Black) Active DI Box

A 10 MΩ input helps preserve the character of passive guitar pickups and piezo instruments. This active DI plugs directly into a microphone-level XLR input.

The 6.3 mm TRS socket accepts an unbalanced instrument or playback-device signal. A single input and XLR output provide a compact route from the source to your mixer or interface.

A Class A output stage maintains a consistent signal as cable length or load changes. The black metal body and gold-plated XLR connector are suited to live and studio work.

The input locking mechanism prevents accidental cable disconnection. It can be disengaged when locking is not required.

The receiving XLR microphone input must supply 48 V phantom power. The DM3 can plug straight into a mixer, interface or stage box without an additional output cable.

Main Features

• The 0 / -15 / -30 dB pad accommodates high-output active pickups, keyboards and drum machines.
• The ground-lift switch offers Off, On and On+ positions. On helps break ground loops to reduce hum, while On+ also tackles higher-frequency noise and radio-frequency interference.
• On+ results depend on the noise source, equipment arrangement and RF environment. It does not remove every possible cause of noise.
• Use the included screwdriver to adjust the recessed switches. Their protected position helps prevent accidental setting changes.
