The RDL RU-SX4A is a compact, professional-quality audio switcher ideal for any application that requires local or remote audio source selection. It features four front-panel pushbuttons for selecting each balanced, line-level input. The inputs can accept either high or low impedance sources. The audio output can drive a balanced or unbalanced line and all I/Os are connected via rear-panel terminal blocks.
Individual level trimmers for each channel are provided on the front panel. The RU-SX4A can be connected to the RCS4, RC4-RU or RUC-4 wall-mount remote controls. A second switcher unit can also be connected and slaved for stereo applications. The durable construction, intuitive interface, and low cost of the RU-SX4A make it a great choice for any audio switching application.
