Sonifex CM-LUX1 Balanced to Unbalanced Converter, Passive, XLR to Phono

This product facilitates the connection of a stereo balanced line input through 2 x female XLRs to a stereo unbalanced output via phono connectors. Featuring transformer balancing with a 2:1 ratio, it adds 6dB of attenuation to the input, aiding in interfacing with the lower signal levels typical of consumer outputs. As a passive counterpart to the RB-LU4 (albeit with only 1 x stereo channel), this unit offers an alternative to the need for specialized cables to interface balanced outputs with unbalanced inputs (such as by shorting the non-phase to ground or disconnecting it). It proves especially valuable when a shared balanced audio feed requires interfacing with an unbalanced input on one or more pieces of equipment. The use of a CM-LUR1 or CM-LUX1 ensures galvanic isolation of the audio, allowing you to connect via phono cables to an unbalanced input without compromising the distributed feed.

Analogue Inputs

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

RCA Phono Analogue Outputs

This unit uses a stereo unbalanced line output on a RCA phono connector with the following connections:
