Do we have to have the impedance matching the volume controls for this to work properly?

Yes, this unit doesn't automatically match the impeadence for you like other volume control units.

You can use a impedance matching audio-former, or I would suggest using a high quality amp. you can buy a amp with 4,6,8 zones @ 30 watts of power per channel that would give more than enough power per pair of speakers plus have complete control with the OSD ATM-7. Make sure your amp & speakers impedance are matching 8ohm amp match with 8 ohm speakers for best results !..

I ran a line level output from my receiver to a Crown 440W amp - that went into the Zone input of this unit. Then the unit will route the amplified signal to any speaker it's attached to - you select speaker pairs with the unit.I did not check impedances but the Crown amp will power a 2 ohm, 4 ohm, or 8 ohm load and the various speakers in my house are 4 ohms or 8 ohmseverything works so I am guessing this auto-matches.

You know . Im actually only running 4 speakers with this . I did switch the impedance to 4 . And I think I does sound a lot better . "Not overload" . I bought it so I can hook up 8 more so total of 12 speakers . One time for some reason when I first set it up . If I would crank up the volume the speakers would sound horrible and the zone selector kept turning off . I couldn't figure out why . But since then it hasn't done it anymore . Sorry I'm lot very technical I hope this helps

Did you make sure that the inline fuse was good? I have had no issues. We did not use the inline volume control and have had great success.

You're impededences are not correct for your speakers and amp. Look online for the wiring diagram. I found it easy. And make sure you are providing a good ground for it.

I just bought one for my fiancé and the volume is not working for his. I think some of the wires are faulty.

yes it works fine! don't worry! as long as your sub is calibrated properly to reference level volume with the rest of your system it should work fine

Make sure that the impedance is compatible (it should be) and it should work with no issues.

Yes - The volume control is on the wire that connects to the sound port on the computer.

I haven't been able to control the volume with my TV controller, you can with a universal controller set up correctly.

It controls volume just fine. And does have an on/off button. Sounds like it should work for you.

The volume control has never worked for me,so I just assume that it worked for outgoing volume

FYI - Impedance matching is the resistive value measured in Ohms. For instance, most speakers have an impedance value of either 4 or 8 Ohms. Headphones can have an impedance value of up to 600 Ohms. Improper impedance mismatching can cause anything from poor quality sound to irreversible equipment damage/failure. Experiment at your own risk or get help from a friend that understands these electronic principles.

Yes it should work however you need to understand that when you have a speaker that has a high peak.. ie 100w etc, it takes more power to drive the speaker. the speaker select just balances the impedance but you will end up dividing the volume level by the number of zones the speaker selector has even if the extra zones aren't in use.. In other words.. you would need a much more powerful amplifier to enable you to hear rich and substantial sound from your speakers. This product was also dead on arrival when I received it. I would go with a more reputable manufacturer instead of this no name brand.. Good Luck!

It works for me. Volume may be an issue if you have the volume control limited.

Unfortunately no. The volume is only controllable by your portable music device's volume levels.

It must be a problem with the receiver.I did not have any problems with the volume.

Mine works great. There is a volume control right on the front for wasy use.

Yea but I imagine the volume control is in your cabinet system, never used it. On back of amp there is a line out return and send. Good sound but not an expert. Sorry
