SpeaKa Professional SP-AS-500 4-Port Cinch Audio Switch Bidirectional Metal Housing

The SP-AS-500 stands out by offering true bidirectional switching in a rugged all-metal chassis, letting you route four stereo RCA sources to one amplifier or one source to four outputs without any active electronics. Unlike plastic switches that degrade signal quality, this passive unit preserves the original analog audio path with zero added noise or distortion.

Highlights

• 4 stereo RCA ports, fully bidirectional: 4-in/1-out or 1-in/4-out
• Passive design – no power supply needed, plug and play
• Durable metal housing with manual push-button selection
• Universal compatibility with any RCA-equipped audio device
• Transparent signal path for pure analog stereo sound

In daily use

Connect your turntable, CD player, tuner, and tape deck to a single amplifier, or feed one source to multiple recorders and zones. Each input/output has its own front-panel button with clear labeling, so switching takes a single press. The compact metal case fits neatly into any hi-fi rack or desktop setup, and because it's passive, there are no hum loops or power-related interference.
