Mini DI Box for Stage and Studio

The Rowin LEF-331 is a passive direct box built for guitarists and bassists who need a compact way to send an instrument signal to a mixing desk or audio interface. Its 1M Ohm input matches high-impedance pickups while the balanced XLR output drives long cable runs without noise. A cabinet simulator and ground-lift switch are built in for tonal shaping and hum reduction.

Consistent Signal Over Long Runs

Because the circuit is passive, the unit adds no active gain stage that could saturate or hiss when the show runs long. The 100k Ohm output impedance and 470 Ohm secondary output keep the signal stable whether you are feeding a front-of-house snake or a studio preamp. True bypass ensures the pedal disappears from the chain when disengaged.

Check Your Power and Connections

The pedal requires a 9V DC centre-negative supply capable of at least 40mA; the adapter is not included. Verify you have a spare 1/4 inch jack for the instrument input and either an XLR cable or a second 1/4 inch lead for the output. The aluminium enclosure measures 93 x 42 x 52mm, so confirm pedalboard space before ordering.

Questions about this item

Does the LEF-331 generate noticeable heat or noise when left on for a full rehearsal?

The passive circuit draws only 40 mA from a 9 V supply, so it stays cool and adds no audible noise during extended use.

What extra gear do I need before the LEF-331 will operate?

You must provide a 9 V DC centre-negative adapter; the pedal ships without one.

Will the LEF-331 work cleanly with my vintage amp that only has a high-impedance input?

Yes — the 1 MΩ input matches classic guitar pickups, and the 470 Ω output feeds older gear without signal loss.
