CM-LUX1 Balanced to Unbalanced Audio Converter
This product allows the connection of a stereo balanced line input via 2 x female XLRs to a stereo unbalanced output on phono connectors.
It is transformer balanced, with a 2:1 ratio, so 6dB of attenuation is added to the input to help interface with the lower signal levels associated with consumer outputs.
This unit is a passive version of the RB-LU4 (though only 1 x stereo channel), and provides you with an alternative to having to interface a balanced output to an unbalanced input via specialist cables (either by shorting the non-phase to ground or disconnecting it).
It is particularly useful where a shared balanced audio feed needs interfacing to an unbalanced input on one or more pieces of equipment. Using a CM-LUR1 or CM-LUX1 galvanically isolates the audio, allowing you to connect via phono cables to an unbalanced input without compromising the distributed feed.
The stereo analogue input is on two female 3 pin XLR connectors with the following pin assignments:
Pin 1: 0V Common
Pin 2: Phase
Pin 3: Non Phase
