    how do i turn off circuit protection?
    A shopper on Nov 24, 2016
    BEST ANSWER: Thanks for you interest in out speaker selectors. Use the SINGLE PAIR DIRECT button to bypass the impedance protection. All outputs are functional. Please be aware of amplifier impedance ratings and total load of all speakers. Zones 1-4 are wired parallel so 4 pairs of 8Ω speakers will present a 2Ω load to each amp channel.
    Can this work with 2 sources on the output side and one set of speakers on the input side?

    I have seen this style of speaker switcher used in this application, not this exact model but basically it is just a multiple output switcher, so I do not see why it would not work on all passive speaker selector switchers.
    Imput connection?
    New User U on Feb 11, 2018
    BEST ANSWER: The input and output are "spring terminals" as seen in the detailed item pictures. They have been around forever, replacing screw terminals decades ago. In case you've never used these before: Strip the ends of each speaker wire about 1/2 inch, twist the wire strands to stiffen up the wire ends. Depress the spring terminal, insert the wire in the connection then release the spring. Even better , "tin" the wire ends with solder first.
    Can I run this switch opposite? One set of speakers, coming out the “input”. And then switch between different receivers. Vintage, tube, etc. Depending one what sound I feel like.. this should work as
    long as only one is switched on at a time.... how would the signal pair direct button work in this set up?
    A shopper on Mar 28, 2018
    BEST ANSWER: No. This device only allows your amplifier to add multiple speakers to your device. If you add multiple speakers to aa amplifier without this device they increase resistance I.e. lower the ohm load to the amplifier causing the amplifier to work harder and cause stress on the output circuit. This device allows you to add up to 4 sets of speakers while maintaining a constant higher ohm load to the amplifier.
    I have 4 Monoprice 4103 speakers. I would like to get this switch and an amplifier to drive them. Ideally I'd like to get a class D amp because the cabinet where speaker wire runs to is small. Any suggestions on what amplifier to use? Thanks.

    I have some vintage gear; 1 receiver, 3 speaker sets (4 ohm, 6 ohm and 8 ohm, respectively) and a subwoofer. I'd like to use the subwoofer with each speaker set independently. Will this do the job?
    Jay L on Feb 8, 2018
    BEST ANSWER: If your subwoofer is the type that gives you a right and left into it and a right and left out of it, go from your receiver out right and left into the sub woofer, then out of the sub woofer to the to the right and left in of the speaker selector box. Connect your speakers to the four speaker connections of the box. I have two set ups working this way, one with a Sherwood S8000 tube receiver and one with a Marantz 2275 solid-state receiver. I generally only use one set of speakers at a time, but according to the speaker selector box instructions you can use more than one set of the time, just use the ohm/impedance protection
    I have two small bookshelf speakers with male RCA plugs for my bookshelf stereo. I want to we these speakers fo4 my tv when not using the stereo. The tv has an 1/8" external audio jack. I want to use a simple switch box to switch between the tv and the stereo. Can this switch box do the job?
    A shopper on Jan 25, 2018
    BEST ANSWER: Not likely. Your TV's 1/8" jack is probably putting out a line level signal; suitable for connecting to a stereo's line level input, such as "AUX In", or any other input (except Phono). This is not a speaker level signal which is a much stronger signal and adjustable with volume control. Sounds like you want an A/B switch but the two outputs you're trying to switch are not at the same level. Better to input the TV audio into your stereo if you have an available input.
    If i have 3 rooms with a pair of passive wall speakers in each, do I need an amp, in addition to this speaker selector?
    A shopper on Nov 13, 2017
    BEST ANSWER: speaker wire from your amp's output is wired to the input in this speaker selector. If you are asking if you need an amp inline from the output of this selector, no. One amp inputs to this, for up to 4 pair/rooms.
    I have a pair of speakers on my patio and I want to add a 3rd one, is this product the right choise?
    Thank you
    A shopper on Jun 8, 2017
    BEST ANSWER: Yes. This takes "one zone" (left & right) and converts to "four zones" (left & right). IE: 2 speakers to this device on zone 1, another set to zone 2 and so on. Then you just turn each zone on as needed by pressing in the buttons on the front. Or just leave them on all the time as I do. I use this product for several applications, one is my outdoor speakers, I have 2 rock speakers in the front of my house (zone 1) and 2 on my rear deck (zone 2) I leave the zone buttons on all the time, but I have installed outdoor volume control for each zone as well which I highly recommend. Hope this helps !
    I have 1 stereo receiver and an audio amplifier with a microphone. I have two 750 watt speakers. Do i need a speaker switch or a mixer?
    A shopper on Apr 14, 2017
    BEST ANSWER: Watts have nothing to do with switching, and what you claim to have has nothing to do with how much distortion you have at high levels of power. You can be very loud, and very annoying, but it has nothing to do with audio quality.
    What does the single pair direct button do? Can I engage it if I am using more than one pair of speakers?
    A shopper on Jun 26, 2018
    BEST ANSWER: This speaker selector allows the use to connect up to four pairs of speakers at once to an amplifier. Some amplifiers can't take it, so a simple safety function was added. This speaker selector's safety function is a crude but effective means of protecting your amplifier from overload if too many speakers are enabled at once. How many is "too many" depends on the amplifier and speakers. When the Single Direct button is OUT, the protection is engaged and a small resistance (4 or 5 Ohms) is inserted in series with the amplifier and the speaker(s). When the Single Direct button is IN, that resistance is bypassed, i.e. the amplifier is connected directly to the speakers. The audible effect is that the speakers are louder for the same volume setting when the button is IN. You may also observe some differences in sound quality with the button IN or OUT, it all depends on your specific amplifier, speakers and listening environment. I had to turn my stereo on and try it out for myself to be sure what it does. My amplifier is a beast and doesn't need the protection, so I keep the button IN. To answer your question, you can engage the Single Pair setting (button IN) if you are using more than one pair of speakers. HOWEVER, if your amplifier is fragile or finicky (most are not) then you should probably leave the button OUT (safety resistance engaged) just to be extra safe. When in doubt, consult your amplifier's user manual or contact the manufacturer regarding proper loading. One more thing: if you have an expensive (over $1K) tube amplifier, you shouldn't even be using a speaker selector. Sorry if this was too long-winded.
    A shopper on May 12, 2018
    BEST ANSWER: 8.5” wide by 5”deep (counting rear connections sticking out). Stands less than 2.5” high.
    A shopper on Feb 4, 2018
    BEST ANSWER: The only protection this unit offers is against minimum Ohms. You can run multiple speaker and the amp will only see a 4Ω load.
    Can I use it for my 3 amplifier to one pair of speaker .?
    Yi Feng Z on Sep 5, 2017
    BEST ANSWER: Not sure what you mean but this is to add multiple speakers to a different zone. For example, speakers in patio, living room etc. you can control which one you want to be playing.
    I have four zones, equipped with 16 ohm speakers. My amplifier can handle from 4 to 16 ohm, so I think I could use the speaker selector with no protection. The tricky thing is that two of the zones have only one speaker. The source is mono so there is no loss of information. The question is if using just left or right channel for two of the zones can be a problem? Thank you

    Confusing Instructions
    Please wait for a site operator to respond.

    You are now chatting with 'TS - Rene P'

    TS - Rene P: Hi Cary! Thank you for contacting Monoprice. My name is Rene P. One moment please while I review your question. How are you doing today Cary?

    Cary: I'm well, how are you?

    Cary: I'm confused because the front of the selector says to engage when using one pair of loudspeakers, but the manual says that when protection is engaged, the amplifier will see at least five ohms. Does engaging the button on the front disengage circuit protection?

    TS - Rene P: The protection of on the switch is recommended if you want to limit the speaker selector to 70w. With it disengaged you would get 140w. When you have the button pushed in the protection is on.

    Cary: so then the statement on the front is wrong? I actually want the button engaged when using more than one pair of speakers?

    TS - Rene P: It is to protect the speaker should you speaker not support more than 70watts. When you splitting a signal it will weaken the output of that signal.

    Cary: oh ok. So engaging the circuit protections limits power to each speaker AND it increases resistance as seen by the amplifier?

    TS - Rene P: Correct, this way have less of a chance damaging a speaker pair connected to the selector.

    Cary: so it is nothing more than an on/off switch for an internal resistor?

    TS - Rene P: Basically yes.

    Cary: So it should really always be engaged to protect the amplifier if more than one set of speakers is turned on, and to protect the speakers if only one pair is used?

    TS - Rene P: Right that would be the way I would suggest.

    Cary: Excellent. Thank you very much for your help!

    PROS: Good quality at great price.

    CONS: Confusing instructions on circuit protection. Hopefully my tech support discussion below will help other folks out.

    4-Channel Speaker Selector
    Directs sound from one speaker pair output to as many a four sets of speakers, either all at once or any combination of the four with a handy push-button switch for each set.

    Monoprice shipping is hilarious. In my case, overnight was a considerably better choice for both price and time.

    PROS: Pretty easy setup (if you consider disconnecting and reconnecting all the speaker wires easy) and doesn't require a separate power source.

    CONS: One volume control serves all. It would be nice if each speaker pair had a volume control. Otherwise, it's a 10.

    4 channel speaker selector
    Using it with a 5.1 AVR by Marantz and purchased it so I can run a set of outdoor patio speakers with the on/off capability. The older Yamaha AVR I had was set up as 5.1 but also had a speakers A and B feature. This one does not.

    Rated as a 10 and although I haven't had it long or used it much yet, seems to work fine.

    PROS: The value for the cost is very good. It is solid and heavy so I think it's well made. It looks nice, not cheap or sloppy.

    CONS: Nothing thus far...

    4 channel speaker selector
    I did not notice any loss of signal quality and one set of speakers is 100' from the selector.

    PROS: easy to connect to.

    CONS: none

    Works well, even with 12 AWG Speaker Wire Connections
    The box is simple but that's part of the charm. This is a no-frills box that sports solid construction and the ability to support 12 AWG-sized speaker wire. Yep, 12 AWG! Mind you, connecting 12 AWG speaker wire may present a challenge but if you cut the ends just the right size, they'll fit in the terminals properly. This little beauty was the key to solving the challenge of switching my home theater's speaker connections between our rears (for Dolby TrueHD and DTS-MA & DTS:X Blu-rays) and our height (Dolby Atmos) channels. This works flawlessly for switching between these channels (yes, along with switching speaker configs on the receiver) and I highly recommend you to get this, if this is the same challenge you're facing.

    PROS: Easy switching between speaker channels in a home theater room, easy connections, no AC power required (passive box) and it will support 12 AWG speaker wire connections.

    CONS: None so far.

    Nice product
    Product works as expected. Installed in garage to an old shelf system, to select between garage speakers and outdoor speakers for patio. Really only needed a 2 channel selector, but for price and quality of monoprices equipment, this was a smart purchase!

    Easy Set up - Works Great
    I ordered this unit to replace a plastic unit that I had been using from Radio Shack. The old unit no longer allowed me to play the two sets of speakers that I have in my back yard (patio and pool). When I received this unit, I was able to quickly set it up, and my issue is now resolved! The music now plays great from both sets of speakers and I also noticed that I don't have to crank my receiver volume up nearly as high to get great sound from both sets of speakers. I also have an inside set of speakers set up and these work great too, but I don't play all three sets at the same time. I would definitely recommend this unit to anyone looking for an inexpensive, easy to set up solution to connecting multiple sets of speakers. When I received the delivery, I was amazed at how solid this unit is compared to the one I was previously using. And, my old one never worked as well as this one! Thanks to Monoprice for providing a quality unit at such a great price!

    PROS: Sturdy Unit

    Easy Set Up

    Works Great!

    Looks Great

    Nice Stickers to label speaker selections

    CONS: None
    June 6, 2015
    Exactly what I needed to route music from my home theater setup into other rooms. However the instructions don't adequately explain the protection circuit. Does anybody know if the button has to be pushed in or left out to activate the impedence protection?

    PROS: Works well. Great price.

    CONS: How does the protection switch work?
    October 12, 2013
    Definitely recommend this unit as a simple effective way to increase speaker sets in your house.
    A great unit and easy to hook up to my amp once I thought about how to do it.
    I would recommend it for anyone needing more speaker sets than your amps have connections for..
    An upgrade would be to put volume control on the switches. Mine are volume controlled on my walls but would be nice to do it at the source.

    Did the Trick
    I have an old receiver with bare wires and 4 speakers in different locations of house. This sweet little unit let me do a simple 1-time wire connection and now I can individually control all 4 speakers, separately or in combination, with a push of a button. I couldn't ask for more.
