Reliable and versatile direct injection (DI) box that converts instrument signals to low impedance balanced signals.
With its superior audio quality, switchable attenuation pad, and ground-lift switch, the AR-133 is the perfect tool for connecting instruments and other line-level sources to mixers, amplifiers, and other audio equipment.
Its compact and rugged design makes it ideal for both live performances and studio recordings.
