My amp manual says "Do not connect the output of this amplifier to any headphone adapter, speaker switch or any device that uses common ground for left and right channels". Can I use a Pyle speaker selector with such an amplifier? This is a newer Class D amp with very different architecture from traditional amps.

please check amplifier specification for compatibility or contact the manufacturer

Can you run this with a car stereo amplifier, for eg. Pioneer GM-D8604? Which gives 2 or 4ohm

The PSLSW4 is not intended for car audio requirement is a minimum of 8 ohms impedance

What office ceiling speaker would I use with this system? I will need 8 speakers low background music only

PDIC60

Can I use 2 of these on one amp? One for “A”speakers,one for “B”speakers.

NO, only one selector per receiver

Can this device support 3 pairs of speakers using my existing Pyle PT560AU 300 watts digital am/fm stereo receiver?

Yes it can

Can this device support a mix of 4 to 8 ohm speakers? If so, what would be the impedance for a mix of 2 each 4 and 8 ohm speakers?

What you can do is to group the 4 ohm and 8 ohms

Ex:

Channel 1 & 2  @  8 ohms  

Channel 3 & 4  @  4 ohms

Is there an internal wiring diagram available for PSLSW4?

There is no available internal wiring diagram

Need help on speaker selection switch PSLSW4, PSLS4.5, PLSHVC412. What are the differences between them? Not interested in the PSPVC4 because of the box connectors. I’ve had a lot of problems with those connectors especially since I have 14 gauge wire. I’m losing left and right side stereo on my existing unit. I attribute it to the connector. I have to wiggle the connector to get both channels. Was very happy with it till the problem. I had it over 10 years.

These are all 4 channel Speaker selector.

 PSLSW4, PSLS4.5,  these are both Binding post Speaker terminals
PLSHVC412 This one uses phoenix connector as speaker terminals

I just bought a house that has 4 Pyle speakers in the ceiling and I have 8 wires behind the TV. I am looking for an amp that connects these speakers to the TV. I am confused on what I need. Would this unit work, or what would you suggest? Thanks.

Hi , I want to buy this item , before that i need to know will this can be used as volume controller and zone selector in Yamaha receiver where the speaker is working in Ohms https://usa.yamaha.com/products/audio_visual/av_receivers_amps/rx-v4a/index.html

The PSLSW4 does not have a zone selector function, which means you cannot assign different audio sources to different speaker pairs. 
You can only use one audio source for all the speakers connected to the PSLSW4.
The PSLSW4 is compatible with speakers that have an impedance of 8 ohms or higher.

Ok, I just want to make it clear I can use this device. I want to plug two stereo receivers in (a vintage Sansui receiver and a Yamaha) and drive the same 2 sets set of speakers (8 ohm) (in 2 different rooms.). Meaning I want to be able to use the Sansui sometimes with other vintage equipment i have connected to it but because I have a bluetooth device connected to my Yamaha I would like to be able use the same speakers (that sound better than the Polks connected thereto.} Hope that makes sense.
