I'm using this product to switch my in-ceiling speakers between the surround output of my HT receiver and a russound MCA-88 which is used for multiroom audio (background music, pager)
Both the Russound MC-88 and AB switch are located in a wiring closet. The HT receiver is located in the living room. The HT receiver is connected to the A-input of the AB switch and the MCA-88 to the B-input.
By connecting the receivers and speakers this way, the HT receiver is "chosen" primally which prevents unwanted A/B switching during low noise scenes a movie. When the MCA-88 zone is enabled the speakers are switched to the B-input which can be used for background music or the pager (doorbell) input.
The sensitivity and delay knobs are an easy way to fine-tune the setup.
A great way to switch between two amps without noticeable loss in quality.

1) When I opened the packaging I heard pieces rattling around in it. Later I opened the unit and a metal part fell out (see picture). I have no idea what it is.
2) When I put in the speakers with no sound sources, channel B was already active (see picture). Explain how channel B can be active and triggering when there are no sources plugged in?
3) The trigger and delay adjustments are embedded. This is terrible from a design perspective. Would it be so hard to put knobs on to adjust with your fingers? I could never tell what I was adjusting.
What I have is a "manual" A/B box. When it is unplugged - Channel A. When it is plugged in - Channel B. That is not what I payed for. Plugging and unplugging the unit is not what I am looking for. I intend to return it. Bad design, bad execution, and broken.
Junk. Does not work. Has parts rattling around in it.

I feel like I spent $75 on broken junk. This unit has both design problems and operational problems. Let me outline them:Reviewed in the United States on December 20, 2018
