There are two types of volume controller - Impedance matching and Non-impedance matching. If you connect your speaker parallel to the receiver or connect the speakers into an impedance protection speaker selector, use impedance matching volume controller. If you connect just one pair of speaker directly to the receiver or your speakers are connected directly into an impedance matching speaker selector, use regular volume controller.

Question: I am interested in your in wall volume controls. Is it possible to connect two pairs of speakers to one volume control unit in one room and one pair of speakers to a second volume control in another room all connected to the same amp? Answer: Yes you can, but the two pairs of speakers have to be connected in parallel. Question: How deep does the mounting box have to be to fit the OSD-VMS-100 volume control into? Answer: This particular volume controls has a depth of 2.9 inches so a mounting box with a depth of 3 inches should be fine. Question: When selecting a volume control, should I match the 100watt or 300watts to the limits of the speaker or the receiver? I have 130W per channel RMS at 6ohms coming from receiver using your SPW8 8 zone panel distribution box. I purchased the 5 x SVC100's for my speakers setting the impedance to 4 on the control. When I increase the volume on the receiver the protection is kicking in sometimes. Answer: SVC100 is good for your setup, the protection kick in is due to the limit power of your receiver.
I dealt with Outdoor Speaker Depot both on-line and via phone. They were quick, accurate, and professional. My item was temporarily out of stock so they proactively upgraded me to a higher end component at the same cost as the lesser model I ordered. I am sure to be a repeat customer. - Dan
You can not beat the quality and price - lpfrnk
Purchased in-wall speaker volume controls and a 4-pair speaker selector switch. Everything arrived a day earlier than promised. Price was very reasonable. Shipping prices were about as expected. They apparently must have been out of stock of the volume controls I ordered, so instead of holding up the order they subsituted then next more expensive model at no extra cost to me. Everything worked perfectly, which is good. I purchased these items to replace similiar items that were purchased locally at Radio Shack. The Radio Shack items were dead on arrival. It was so nice to take these items out of the box, install them, and have them work perfectly. Even after paying for shipping they cost less than the Radio Shack items that never worked. I had a very good experience with Outdoor Speaker Depot. Before I placed the order I called their Technical Suport number and spoke with a real, live person who was very helpful and confirmed that all the items I was ordering were compatible with each other. - David
I have three of these. Had a problem with two not working initially, but OSD replaced them with no questions asked. They work perfectly. The only reason I give 4 stars instead of 5 is that the color and size does not match perfectly with other decora wall plates. Since I have two zones outside I wanted a dual gang plate and had to modify one from HD to work. It looks OK though. Other than that issue, OSD makes excellent products and I have been very pleased with all my purchases. - Josh
I had very little idea of what I needed, but I called the help line and was able to speak to a SUPER knowlegable person who helped me find EXACTLY what I needed and didnt try to upsell me on anything, in fact told me I didnt need the more expensive version. The price was GREAT, the shipping was quick and reasonable, the service was excellent! I havent actually installed it yet, but it looks like a great product. I couldnt be happier and cant wait to buy more electronics equipment so I can shop here again!!! - Wendy from Chicago
Enjoy music anywhere in your home without frying your amp! Impedance matching is the only way to go -- this control makes it easy to do it right. Good quality at a great price! - Greg
Always a pleasure dealing with these guys. I emailed some
questions to them, before I tore out my walls, regarding how best to wire the
house for audio. I received a prompt and explicit description of what I
would need to complete the project. A year latter the walls are sealed
and I have the best sound system on the block. - Ben
Got six of these plus the six room selector. They work as good or better than Speaker Craft and Niles for $80 less each! Three different color plates is a huge convenience. Unreal. I was screwing in the speaker wires directly, struggling with the tight fit, and finally realized the connector base pulls off the pins. Makes screwing in the wires easer. Just plug the bases back onto the unit. Don't mix up the INPUT and OUTPUT labels if you do remove the terminal bases. - Kent
Good price, happy with the quality of the products delivered, shipped the same day I ordered, received quickly. No surprises. Would order from them again. - Mark
Thank you for making my purchasing experience a good one. Overall I rated the purchase a 4 out of 5. Your pricing and the actual products: speakers, volume controls and speaker selector were excellent. I was impressed that the products arrive as projected. Everything was installed the very next day and works great.
I will recommend your site and vist again in the future. - Larry
The VMT-100 is a high quality unit that does everything it claims. I have Niles volume control and speaker selector in my previous project. After installing the volume control and speaker selector for my basement. I have no loss of signal or quality of sound even when all 7 sets of speakers are blasting. The impedance matching unit protects your amp by ensuring it does not get overloaded. I'm very happy to find these two products at the 1/3 price I've paid for Niles products and function exactly the same. - Darryl
Good build quality and nice sound, I like the fact that all OSD brand volume controls come with three color plats and knobs, I have customers painting their rooms in different colors, no need to order extra colors for inventory. - Chris
The web-site was easy to use and very helpful recommendations to get me what I needed. - SW
the products arrived promptly and well packed. However, the best thing for Outdoorspeaker Depot is the unbeatable prices. - Ho
This volume control is very easy to instal and use. The fact that it comes with multiple color plates is a bonus.
The only drawback to I found is that the terminal block that the speaker wires attach to does not seem to attach well if you remove them to install the speaker wire. - thabeezer
Good product. Fair Price. Everything was delivered as agreed--without delay. I would recommend OSD and will purchase from them again. - Greg
These controls work as advertised. The audio input and output terminals can be slipped off the circuit board for ease of connection. Inputs and outputs are clearly marked
If you are in a commercial building like mine, some of the walls use 1/2 thick steel studs. There is not enough depth within the wall for the control. I added a surface box and all is well.
I'd buy this product again in a heart beat. - X-Ray Dan

I would like to know if this volume control will work on my two speakers I have on my patio/deck. The speakers are connected to the main amplifier in my living room...the speakers are weather proof..we have sound, but I have turn the stero up in the house real Loud to here the speakers outside. Will this volume control work ok with my setup??right now the patio speakers are on an on/off switch..thanks for your reply

Answer:
As long as the speakers are 8 or 4 ohms & each wired individually, this volume control should work just fine. It is not an outdoor volume control, so it will have to be placed indoors or somewhere where it is protected from the elements.
By Philip from Ohio on January 6, 2012
Does this control turn the speakers off the the volume is all the way down?
By Customer Service - Q&A on January 6, 2012
Answer:
Philip,
This volume control would regulate the electrical current your speaker is receiving, If the volume on your amp / receiver is up and the control is all the way down, there could be a very minimal amount of volume still noticable (less than 10%) Although we do have a volume control with an On/ Off feature.Take a look at the SVC205.

How deep is this item. I'm afraid the electrical box I installed may not be deep enough. What are all the dimensions?
By Customer Service - Q&A on October 20, 2011
Answer:
The depth on this volume control is just shy of 3".
