Sonifex CM-LUR1

Balanced to Unbalanced Converter (RJ45 to Phono) 

This product allows the connection of a stereo balanced line input via RJ45 with StudioHub+™ pinout to a stereo unbalanced output on stereo phono connectors. 

It is tranformer 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 compomising the distributed feed.
