Audio receivers with balanced XLR input

 

— audio line input using balanced connection via XLR — characteristic round 3-pin plug; one input consists of a pair of these connectors, for the left and right stereo channels. A feature of a balanced connection is that the XLR cable itself dampens external interference coming to it; and the connector provides tight contact and is often supplemented with a retainer for reliability. All this allows you to achieve high quality connections and maximum purity of sound, even when using long wires. However, such inputs are rare — this is due not so much to their shortcomings, but to the fact that audio receivers are rarely used as linear balanced audio receivers.
