Do the volume controls control the source volume or the speaker zone volume? The description says source volume, but don't think that makes sense. Would make more sense for them to control the speaker zone volume. Thx!

BEST ANSWER: The volume controls are actually attenuators. So the decrease the input signal rather than amplify it. The volume will only get as loud as the input. So to adjust the volume to the zone you must turn up the volume from the source device as loud as you would like it and then lower it using the volume knobs on the Speaker Selector.

It is the zone volume. Overall this unit works well, but there does seem to be a bit more attenuation in the signal when passing the signal through this device than I had anticipated.

If you intend to use the 25 watt amp the answer is probably not.
It depends on how efficient your speakers are.
FYI--the speaker selector would have no impact on the sound volume (unless you turn volume knob down on the selector).

can I connect 4 speakers for one room and one amp to this unit?
A shopper
on Jan 30, 2017
BEST ANSWER: There is only one set of inputs (1 positive and 1 negative lead) and two sets of outputs (1 positive and 1 negative lead per output). You would have to run your receiver out to your input amp, then your amp out to this switch input..then you could run the 4 speaker leads to this switch outputs. You'd have to engage both speakers on from this switch to feed all 4 speakers. The only separation you would have is left and right versus front left, front right, rear left and rear right.

Yes, as long as your amp has outputs for two sets of speakers, you run the four sets of speaker leads (eight conductors total) to this unit (A left + and -, A right + and -, B left + and -, and B right + and -), then there are four matching outputs that go to your speakers.

BEST ANSWER: This unit should work for you. It is designed for two sources and two pairs of speakers. In your case, the amplified source would go to the MSV-2 and both sets of speakers would connect to the MSV-2. Your source selector would always be either A or B and never need to be changed while the on/off button would control each pair of speakers. The volume controls could be set for each speaker. Remember - you will also need to set the volume on our source and for this reason you will have three options to adjust volume.

I assume wiring this way connecting a single pair (front left/right) to the switch will change the Ohm load to the deck to 4 Ohm's when I select sound out both Zone 1 and Zone 2, But the Ohm load would stay at 8 Ohm's if I run only one of the zones. Would this not be essentially the same thing as putting in a basic in wall "A" "B" switch such as those by Levitron or your https://www.monoprice.com/product?p_id=38176?
It would be either/or to the sw input from the car stereo.

Does 100w "per channel" mean 100w on A and 100w on B? Or does it mean, for instance, 100w R side A, 100w L side A = 200W for A and vice versa for B.

BEST ANSWER: This selector is rated for 100W to the left and to the right for a total of 200W. As most receiver/amplifiers show their power rating as xxW per channel you can have two amps rated at 100W per channel connected to the A & B inputs.

Your second assumption is correct, when they said 100 watts per channel, it meant the max input power is 100 watts (each side). As "stereo" means two, two outputs to two inputs (an stereo amp to two speakers). Now a days, manufacturers would say their stereo equipment can output 700 watts (not) in 7 channels, meaning adding everything up and X 2.

"Powered speakers" are speakers that don't need an amp—they have their own amps built in (common example: small desktop speakers hooked up to your home computer). That means the signal coming to the input of the unit would be unamplified.

This is only two audio sources in and two audio sources out (2 channels for each.) Source A = 2 channels and source B = 2 channels. If your amp has a way to sum up all 5.1 to 2 channel out, this would work... this will not take a 5.1 mix and balance out to 2 channels though, if I am understanding your question correctly. Works great to send a stereo mix from the amp to the switch.

A shopper

BEST ANSWER: So, on the rear of the unit, there are two wiring blocks. When looking at the rear of the unit, the left block, has TWO inputs. Use just the A input Right and Left, FROM the amp. Next, the block on the right has A and B outputs (Left and Right), wire the first set of speakers (Left and Right) to the A output, and the second set to the B output. Only use the A Source, the select which speakers you want to hear the source on. You can add a second source at any time. Hope that helps.

You need an amplifier (like the tube amps on Monoprice).
You’d then connect speaker wire from the speaker terminals on the amp to the input on the speaker selector.

From the receiver, run your speaker cables to the input of the switch….then hook one set of speakers up to “A”, the other set to “B”.

BEST ANSWER: This speaker selector is designed to run from an amplifier to two sets of passive speakers. Both outputs have on/off switches and volume controls. You can turn both sets of speakers off.

If I understand your question, the anwer is 'yes'. This box is a simple switch, so the feed line ('post amp') gets distributed to both the A and B channels. Those channels can be turned on and off independantly. It is an un-powered box so there is no power switch on this.

at higher volumes my speakers sound muffled, I am running 4 speakers total, two sets in different areas. . When I disconnect the selector box and run direct through my amp they sound fine. any suggestions. Thinking I should return unit , as I can't use as is. I have double checked all of my connections. could it be my wires?

It is possible that your amp cannot push 2 sets of speakers at the same time, or, they are too far away, if so, please try using one pair only at a time, or try different wire, usually lower gauge ones, I use 14 gauge

I am considering this to add to an amp that only has one set of speaker connections to use the speakers in my living room and my kitchen since they are already hard wired in. The amp is 100 Watts, the living room speakers are 6 ohm and the kitchen speakers are 8 ohm. Will this work for me needs?

my receiver has an A/B switch and i have two pairs of speakers in different rooms connected to the receiver. However, when i run them both, one set is much louder than the other. Will this switch allow me to set the volume individually per pair to have the same volume on both sets?

BEST ANSWER: Yes, this is a passive selector so it will not boost signal but you can use it to attenuate the dominate side to match the weaker side.

The switch will allow to control the volume to each set individually, Meaning each side has two inputs and two outputs. You would need to piggyback the receiver input 2 times to control 2 sets (four speakers).
Double check the connections at the receiver first. Whether a 5 channel or 7 channel receiver each speaker output provides a different sound and volume. Some receivers have an simulated stereo option that lets you power all the speakers connected equally.

I have a whole home speaker system with volume controls in each room. At the media closet only 2 sets of cables (4 total wires, 2 red and 2 black) come out. Battery tests move all the speakers in the system when testing each set. I have tested impedance at 1.2 for each set and numerous receivers either don't work or work for a short time then shut down. I currently have a 4 ohm receiver and would like to purchase this to connect to the speakers and input my current receiver to the system. Has anyone has a similar situation with impedance? Will this selector level the impedance between the two (receiver and speaker system) ?

BEST ANSWER: I have a 200 watt tuner /amp I split 2 channels into 6 speakers they are 100 watt 4 ohm, I installed this to regulate 2 speakers in my lobby, to an inside level, 2 outside speakers which I turn up for out side use also 100 watt 4 ohm. The full 200 watt goes directly to a stand up tanning system which adjusts the level automatically for its built in speaker. The 6th wire goes to a room with a laydown tanner also full 200 watt. I purchased a single line volume control for that room. Each volume controller maintains the wattage and impedance, so I have perfect sound at the levels I need for each location. The amp, volume controllers, and speakers should be the same ohm. Because I needed 3 rooms controlled manually/independently I installed the 2 channel and a single channel I use the master volume control to adjust the volume in my stand up tanner the other three locations are controlled by the double monoprice controller and a single in wall controller also from monoprice. Perfect volume levels from minimum to maximum with no issues. GOOD LUCK, I HOPE THIS HELPS!

Bad vollume control
With the volume control on the right, the next to the loudest setting, no sound comes out of the right speaker. They don't have any more and will only offer me a refund. I would prefer to wait until they get some more in and then exchange it.

Monoprice is a GREAT co. with great produicts. However MY MISTAKE in ordering this 2 channel, not knowing the technicalities of impedence compatability etc. had to send back so can't rate this one. However with further knowledge from Don Edwards from there tech dept. found the right one for me. So between returning and reordering they again are a grreat co. and great customer support. Thanks.

Great box, just ordered another one for another pair of vintage receivers.
Works perfect for my setup. I?m running two vintage receivers feeding four Klipsch speakers, a pair of KG4?s and a pair of Heresy 2. I can choose to listen to one receiver and use 2 or 4 speakers or change to the other receiver and listen to 2 or 4 speakers, without moving speakers wires around or running double wires to the speakers from multiple amps risking burning something up. The box does rob some of your dB?s as you?ll have to turn the receiver up higher than normal but it?s worth it for the convenience. I?d recommend stripping just an 1/8th inch off the speakers wires when attaching to the box and use a jewelers screw driver.

I have had this device outside (under a covered porch) for 6 years of 90+ humid summer days and near zero winter days. Had a few spiders, bees nests, etc over the years with no issue.
