AVer ST42 4-in 2-out RCA audio signal routing

4-in 2-out RCA audio routing

The AVer ST42 is a passive signal router that lets users connect up to four stereo sources and select between two output paths using gold-plated RCA jacks. No external power is required, so installation is a simple plug-and-play affair. The aluminium chassis and solid rotary knob provide a sturdy feel for desktop or rack use.

Suited for multi-source stereo setups

This unit fits installations where several analogue sources such as CD players, streamers or phones must share a pair of amplifiers or recording inputs. It also works in reverse, sending two sources to four destinations. Buyers who need balanced XLR connections, digital audio formats or remote switching should look elsewhere.

Four inputs and two outputs

In standard configuration the switcher cleanly handles four stereo inputs routed to two selected outputs, giving ample headroom for typical home or project-studio source counts. Running the box in reverse mode supports two inputs distributed to four outputs. The passive design adds no gain or noise, so signal quality depends entirely on the connected gear.
