4-CH High Power Stereo Speaker Selector

My 26-year-old Sony AM/FM receiver died, and the comparable Sony replacement unit lacked a second set of wired speaker jacks ("B") like the old unit had. [FWIW, as far as I could tell after searching really hard, no current Sony receiver accommodates a second set or wired speakers, nor do they include an AM tuner...sigh...]. This Pyle device provides that missing speaker function. I can now (again) listen to only "A" (along with the rest of the 5.2 options in the family room), or just "B" in the kitchen, or even "A" plus "B". To use the Pyle device, I ran four wires from the new receiver's main front L&R jacks into the input of the Pyle device, and connected the main front L&R speakers to the Pyle's output for switch "A" and connected the satellite speakers in the kitchen to the output for switch "B". Note: I did have some concern since all four speakers are 8Ω, and worried that having A &B engaged simultaneously might result in impedance mismatching; however, that seems not to be the case -- or at least, not to the point that causes any problem for the switch or the receiver's amp, both of which include "protection" functions. I would recommend this product.
