4-in-2-Out RCA Stereo Passive Audio Switcher — Manual Push-Button Speaker Selector (300W per Channel)

Passive RCA stereo switcher that lets four power-amplifier sources be routed to two pairs of stereo speakers. Inputs are chosen with push-button controls; each of the two speaker outputs can be opened or closed independently, so both speaker sets can play at once or one group can be turned off individually. Maximum power handling is 300W for each channel. The unit provides a no-load protection function for vacuum tube power amplifier signals. Designed for manual input and output switching with plug-and-play operation; switching is stable and will not produce pops, clicks or other noise between channels.
