Stereo Balancing Gadget
Professional applications use balanced audio for good reason. Balanced circuits offer many performance advantages compared to unbalanced audio, such as increased headroom and reduced noise from radiation and ground differentials. Sometimes, though, unbalanced devices are unavoidable. The Stereo Balancing Gadget was made for those times.
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, our circuitry maintains 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 Gadget eliminate the hum and buzz of a ground loop, it also eliminates noise from external sources such as power lines and digital noisemakers. You can even run long unbalanced cables between gear. Balancing Gadgets make it possible to use unbalanced equipment in professional applications without compromising performance.
The Stereo Balancing Gadget converts unbalanced stereo -10dBV consumer audio via two RCA/Phono jacks into professional +4dBu fully balanced lines on two XLR connectors. The precision direct-coupled transformerless analog circuitry is powered by an internal low-noise linear power supply capable of supporting +24dBm output levels without breaking a sweat.
From the powder coated steel enclosures to the carefully curated electronic components, the Stereo Balancing Gadget is built for the realities of radio. Yet the precision analog circuitry delivers stunning sonic transparency that would be right at
home in the most discerning recording studio.
