What this switch does

The ATNEDCVH AS-402 is a passive bi-directional audio selector that routes stereo signals between RCA and 3.5mm connectors. It handles two RCA plus one 3.5mm source feeding four RCA plus one 3.5mm destination, or the reverse, using front-panel knobs to choose the active path without any external power or drivers.

Who it suits and who it does not

It suits listeners who want to share one pair of powered speakers or a headphone amplifier across several source devices such as a computer, phone and turntable. It also suits the reverse scenario where one source feeds multiple zones. It does not suit installations that need remote control, automatic switching, balanced connections, or more than four simultaneous input or output devices.

Capacity and headroom

The box provides eight physical ports arranged as two groups of four RCA plus one 3.5mm each, allowing up to four sources and four destinations in either direction. Signal passes through hi-fi grade circuitry for low noise and transparent switching. Because it is entirely passive, there is no gain stage; very low-level sources may need a pre-amplifier before the switch, and very long cable runs can introduce capacitance that the unit does not compensate.

Questions about this item

What source devices with RCA or 3.5 mm outputs do I need to connect to the AS-402's two or four input ports?

Connect up to four source devices — such as a TV, computer, smartphone, turntable, DVD player, DAC or amplifier — using their RCA or 3.5 mm cables to the switcher's input side.

Can I keep my existing amplifier and speakers that only have RCA or 3.5 mm inputs while using this switcher?

Yes. The AS-402 provides two or four sets of RCA and 3.5 mm outputs, so your current amplifier, powered speakers, soundbar or headphones plug in directly without adapters.

How do I confirm the AS-402 is routing audio correctly after I wire everything up?

Turn the selector knob to each position; you should hear the chosen source play through the connected outputs with no noise, and switching should be silent and instant.
