About BSS AR-133

An indispensable tool for professional audio setups, the AR-133 Active DI Box is designed to seamlessly convert low-level, high-impedance signals from electronic instruments such as guitars and keyboards into low-impedance balanced signals compatible with professional sound mixing consoles. This high-quality DI box is crucial for preventing signal loss and degradation over long cable lengths, ensuring a clear, robust sound in both recording studios and live sound setups.

The AR-133 Active DI Box features switchable input attenuation, offering 0dB for guitar-type pickups, -20dB for line level signals, and -40dB for speaker feeds. This versatility allows it to match the level and impedance with unity gain without loading the source, making it a reliable choice for a variety of audio applications.

This professional-grade DI box is powered either from console phantom power or an internal battery, providing a fail-safe operation. In case of phantom power failure, the device automatically switches over to battery power, indicated by a flashing LED.

The AR-133 Active DI Box also includes a Parallel Link Jack output for directly feeding amplifiers and a Parallel XLR input for converting unbalanced outputs to balanced lines. This ensures optimal signal quality and reduces noise, enhancing the overall audio experience.

Built on the enhanced design of the long-established BSS AR-116, the AR-133 Active DI Box is recognized for its outstanding sound quality, particularly with acoustic guitar and bass guitar pickups. However, its uses extend beyond guitars and keyboards. It's an ideal solution whenever there's a need to match levels and impedances, isolate sources, or use long cables.

The AR-133 Active DI Box is also equipped with both jack and XLR connectors on the input, extending its compatibility with a multitude of source devices. Whether you're a professional musician, sound engineer, or audio enthusiast, the durable and versatile AR-133 Active DI Box is a valuable addition to your audio equipment collection.
