EZ-SX4X

RDL EZ-SX4X - switch for 4 stereo audio RCA sources with output volume control

The RDL EZ-SX4X from the EZ series is a stereo audio source switch with linear output level control. It allows the selection of one of 4 stereo signal sources and sends it to a power amplifier, mixer, recorder, computer, or other device with a line input. The unbalanced inputs and output are provided on gold-plated RCA jacks on the rear panel, and source selection is done via full-sized, mutually blocking buttons on the front panel. Signal switching is performed using semiconductor technology, and the knob on the front panel allows for output level adjustment from off to +12dB gain, enabling direct connection of the switch to a power amplifier. Sources with line or headphone outputs, such as tuners and amplifiers, CD players, computers, televisions, mixers, or personal audio players can be connected to the inputs. The device is suitable for shops, places of worship, restaurants, clubs, home audio systems, and commercial sound systems. The EZ-SX4X version comes with a universal power supply with a plug suitable for the destination country.
