The BSS Audio AR-133 Active DI Box / Line Balancer is a versatile and high-performance device designed to deliver clean, high-quality audio from a wide range of instruments and electronic sources. It’s the ideal solution for those looking to convert unbalanced signals into balanced outputs, ensuring superior sound quality and reliability for live performances, studio recordings, and various other audio applications.

Reliable Phantom Power and Battery Backup
One of the standout features of the BSS Audio AR-133 is its ability to run on both phantom power and internal battery, ensuring uninterrupted use during performances or recordings. When phantom power from the console is lost or accidentally switched off, the AR-133 automatically switches to the internal 9V battery, providing continuous operation without any disruption. This backup feature makes the AR-133 a dependable choice for live sound engineers, musicians, and audio professionals who can’t afford to lose signal integrity mid-performance.

Durable and Distinctive Design
The BSS Audio AR-133 is housed in a rugged aluminum extrusion case that ensures durability, even in tough environments. The addition of robust polyurethane end-cheeks gives the unit a unique, distinctive look while providing extra protection against bumps and impacts. Whether you’re traveling with the unit to gigs or using it in the studio, the AR-133 is built to withstand the rigors of regular use while maintaining a professional appearance and functionality.

Flexible Inputs and Balanced Outputs
Designed with versatility in mind, the AR-133 features both 1/4" jack sockets and an XLR socket for input connections. This flexibility means that the AR-133 can handle both unbalanced and balanced signals, allowing users to easily convert unbalanced inputs into balanced XLR outputs. Whether you're working with instruments, line signals, or amplifier outputs, the AR-133 can seamlessly integrate into any setup, making it a great addition to any musician or engineer’s toolkit.

Convenient Cable Management and Input Attenuation Options
The BSS Audio AR-133 features an arched case design that allows cables to run underneath the unit for neat and tidy cable management. This thoughtful design keeps your setup organized, reducing clutter and potential tangles during use. The unit also offers input attenuation options of 0, -20, or -40dB, making it adaptable for different input levels, including those from instruments, line signals, or amplifier outputs. Whether you’re using a bass guitar or a keyboard, the AR-133 ensures your signal remains clean and strong.

Ground Lift for Easy Troubleshooting
Another useful feature of the AR-133 is its ground-lift switch, which provides a quick and easy solution to ground-loop problems. Ground loops can create unwanted hums or buzzes in your audio signal, but with the AR-133’s ground-lift functionality, you can solve this common issue with just the flip of a switch. This feature makes the AR-133 an invaluable tool in a variety of settings, from live performances to studio recording.

Legendary Sound Quality for Multiple Applications
Known for its legendary sound quality, the AR-133 uses an enhanced version of the audio path found in the AR-116, which is regarded by many as a reference standard in the industry. The AR-133 delivers exceptional audio quality, particularly when used with acoustic instruments like guitars and basses. However, its versatility extends beyond traditional guitar use. It can be effectively used with keyboards, DJ consoles, amplifier outputs, and other electronic sources, making it suitable for a wide range of audio applications in different settings.
