Angry Audio Stereo Balancing Gadget

Converts unbalanced stereo -10dBv audio via two RCA/Phono jacks into professional +4dBu fully balanced lines on two XLR connectors. Ideal for a single playback-only consumer device. State-of-the-art analog circuitry is low-distortion, low-noise, and includes DC offset correction and our exclusive input stage that reduces ground-loop noise.

Groundbreaking Technology

The most common problem when ingesting unbalanced audio is the ground differential (often referred to as a “ground loop”) between source and destination equipment.  Unwanted noise appears on both the signal and shield conductors of the connecting cable.  Buzz and hum are the usual symptoms, but ground loops are also notorious for creating a path for RFI. Our exclusive active input circuitry dramatically suppresses common-mode noise on unbalanced sources.  Though it is similar to an active differential input as used for balanced audio, it is able to maintain high CMRR (common mode rejection ratio) even when the source impedance is mismatched as is the case with unbalanced audio sources.   Not only will the balancing gadgets eliminate the hum and buzz of a ground loop, it will also reduce noise from external sources such as power lines and digital noisemakers.  You can even run long unbalanced cables between gear.  The balancing gadgets make it possible to use unbalanced equipment in professional applications without compromising performance.
