Built-in active amplification circuit boosts weak instrument signals—ideal for low-output passive pickups on acoustic guitars, vintage basses, and other instruments where passive DI boxes cause noticeable level loss.

High input impedance preserves your instrument's natural tone and frequency response; unlike transformer-based passive DIs that can load down passive pickups and dull high frequencies.

Dual power option: operates on standard 9V battery (included) or 48V phantom power via XLR from mixing console—battery automatically disengages when phantom power is detected, saving battery life.

Switchable input attenuation provides -20dB pad for hot signals from active electronics or line-level sources, preventing preamp clipping while maintaining clean headroom.

Rugged all-steel chassis withstands stage and studio abuse; compact design fits easily in gig bag or pedalboard without adding significant weight.
