Question: Can it play audio to up to 6 pairs pf speaker all at the same time or one channel at atime?
Document: I am by no means a home audio expert... but...The description states:Handles 100Watts Per Channel with Speaker Systems that have a Minimum Impedance of 8 OhmsI read this as the lowest it would drop the impedance is 8 Ohms, which my receiver is capable of. After opening the item, the manual states it will drop the impedance to 1.7 with all 6 speakers operating.
Wire hook up for speakers is a little bit delicate. When I have all speakers going, channel 6 at around mid point will cut out. I have to lower it one notch and then it works. Otherwise it works great. It does not have volume fine tuning instead it clicks when turning the volume up. You can always use your master volume on your stereo for fine tuning. all my speakers are 60oms. 4 channels have 2 speakers each at 60oms. the 5th & 6th channel each one speaker.
I bought this under the same impression as several other buyers - that it would not drop impedance and that you could safely run all 6 pairs of speakers at the same time. I connected everything up without reading the detailed manual like some of the other reviewers, and it works as I EXPECTED it, but maybe I'm not using it as Pyle intended it. Receiver output into unit.
i have speakers throughout my entire house. I wired them myself and used to just have them hooked up to a receiver, but I thought I'd get serious and upgrade to this speaker selector box. In my experience, Pyle really makes some quality products and this box is no exception. 100 watts per channel is quite powerful, and a frequency response of 20Hz-20KHz is just what I need. My whole home is an audio system now. Truly awesome.
For some reason my sub woofer was always louder than the rest of my speakers, this was annoying since there was no way single out speakers individually and adjust the volume from my receiver.The pyle pspvc6 6 channel does the job well and I still have an extra couple ports if i want to add more speakers later.I am now in full control and getting the sound i wanted.
I researched this product and found numerous sites that state it is an impedance matching speaker selector. Little did I know that it is not! After order the product and opening the box, the product manual states that the more speakers you are playing / using, the lower the impedance. I have to return the product and order a new one....hopefully Amazon will help get this taken care of, will update when I get this straightened out.
The Pyle Home PSPVC6 6Channel High Power Stereo Speaker Selector with Volume Control meets every claim made for it. It was about the same price as other 4-channel selectors; a couple of channels for free and it works flawlessly.
Works just as it should no problems, a pleasure to use. Controls six pairs of speakers at whatever level I want.
product was delivered on time, good quality, easy to install, met all of my needs, I like the fact that volume level is step selectable which makes for sure consistent settings
This product is what I needed to setup a sound system at a restaurant. Whoever originally installed the system daisy-chained several pairs of speakers together and it was blowing out their receivers. I undid the daisy chain and ran the speakers independently to this 6ch selector and it relieved the receiver from being over-worked and blown. This unit protects the receiver and allows volume control for the speakers in sections.
Answer: All at the same time. This unit is made to do just that.
