BSS AR-133 Active Direct Box with Phantom Power, Pad Switch, and Balanced XLR Output

The BSS Audio AR-133 Active Direct Box is a professional active DI box that converts unbalanced instrument, line, and speaker signals into balanced XLR output for studio recording, live sound, and AV applications. It also functions as an active balancing device, ensuring clean and reliable signal transmission. This makes it ideal for musicians, audio engineers, and professional audio systems.

The AR-133 features a rugged aluminum extrusion case with durable polyurethane end-cheeks for long-term reliability. Additionally, its arched enclosure allows cables to be routed neatly underneath the unit for clean and organized cable management. This design helps maintain a professional and clutter-free setup.

The unit operates using standard 48V phantom power from a mixing console or an internal 9V battery (not included). If phantom power becomes unavailable, the AR-133 automatically switches to battery power. As a result, it ensures uninterrupted performance during live use and studio recording.

The AR-133 is suitable for guitars, basses, keyboards, DJ consoles, amplifier outputs, and audio interfaces. Furthermore, its high-quality circuitry ensures accurate signal conversion with minimal noise. This makes it suitable for studio recording, live sound, and AV installations.
