Features & Specifications

Speaker selectors like the DSM8 allow you to distribute an amplified signal to multiple zones throughout the house without losing audio quality. These units also have manually activated impedance-protection circuits that protect your amps or receivers from low impedance levels as you add more speakers to each zone. With independent a/b switches per zone, the DSM8 dual source 8-zone speaker selector lets you input two music sources, for instance, iPod library and satellite radio, and choose which source will play in a designated zone. Keep in mind that playing different sources in different zones at the same time requires separate amps or receivers to power those sources. The a/b switches are a convenient way to switch from source 1 (amp A) to source 2 (amp b).


• Removable input/output connectors which accept 14 gauge speaker wire
• Four color display packaging
• Eight zone speaker selector
• Dual source with manual protection switch
• Removable input/output connectors

I'm looking to power 32 Speakers using 2 of the DSM8's. The speakers are rated at 50W RMS a piece. Would I need to buy 2 Amp200's and 2 Amp300's bridged mono to do this?
1 Answers
Hi Matt, I think you would be fine with the AMP200, however running it in bridged mode may be too much for the speaker selector to handle. It pushes out a lot of power in bridged mode. Are these mono speakers or are you just not running two speakers in each zone?

Chris
from Knoxville, TN asked:
February 12, 2015
If you select all the speakers to be on at one time, I guess you're dividing the Wattage output of your amp by 8 to each channel? So an amp with 100 Watt output through the 8 output selector with all outputs on would be 12.5 Watts per channel? Thanks in advance
1 Answers
HI Chris: There are other factors involved. Are you planning on using Volume Controls with this speaker selector (recommended to handle Impedance matching) or depending on the protection switch on the unit itself. When using the internal protection you will notice the power output is cut in half just because you are sending the audio signal through the internal transistors.What amplifier are you planning on using also is another factor. As an example we do not recommend using the zone 2 output of a Audio Video Receiver to drive a Speaker Selector with 8 pairs of speakers (neither does any of the Receiver manufacturers either according to most Owners manuals). We sell many AMP200 and AMP300 which are true audiophile quality High Current Amplifiers that do not limit their output when the impedance drops from 8 to 4 and even 2 ohm. So the point is there are additional variables when trying to calculate how much wattage is delivered to each speaker. TL/3141

Can I connect each speaker with an Impedance matching speaker volume control Knob
1 Answers
Hi Khurram, This speaker selector has built in impedance protection which you can either enable or disable. If you want to use impedance matching volume controls for each zone, you would want to disable the impedance protection on the speaker selector itself.

from DYER INDIANA asked:
June 6, 2014
can i connect this to a onkyo 2 channel amplifier to get better sound to my 6 speaker zones cause im having to raise the volume controls all the way up to get good sound
1 Answers
Hi Sal, It isn't recommended because that receiver is only built to handle a pair of 8ohm speakers. If you add more than a pair, you'll be lowering the impedance to 4ohms, 2ohms and below. Even with the impedance protection of the speaker selector, the receiver will still see an unstable load. What you would need to provide ample power to your 6 zones would be our AMP200 or AMP300. Each of these can be used in line with speaker selectors. Let us know if you have questions. Thanks! BM 2736

from Orange County asked:
April 21, 2013
I have an Onkyo 616 receiver that I will be using to power a 7.2 outdoor surround sound system in my 5500 sq/ft backyard. I already have seven RS800 rock speakers from you guys for this. In addition, I will also be powering 8 additional speakers in different zones of the backyard. My plan was to buy AMP200 to power the 4 pairs of speakers, and an SMP250 to power 2 8 ohm outdoor subwoofers. My two subwoofers are going to be on opposite sides of the outdoor theater and I will need a way to control the volume levels of the subwoofers to allow proper integration. If I was using the SMP250 to power the two subwoofers I don't think I would be able to control the levels of the subwoofers independently of each other which is where I think the DSM8 would come in. Could I run both amps to the speaker selector and control the levels to the 4 pairs of speakers and 2 subs? In a somewhat related question, if one pair of the speakers ran by amp200 was with the center channel of the 7.2 system would the sound from each speaker be ouptut without any delay in sound? Hopefully that makes sense. In other words, would the center channel being powered by the onkyo receiver be ouptut at the same time as the two speakers being powered by AMP200. I don't think that the amp200 powered speakers would add to the center channel volume because they would be played in stereo fashion instead of integrated into the 7.2 system. How would I increased the volume by the center channel during movies without just increasing the gain in the Onkyo 616 of the center channel? Thanks.

Hi Matt, Subwoofer location will take some experimentation to find the ideal spot for the maximum bass for your prime viewing/listening area. Try and find a prime location with a single amp first but keep in mind that the best way to get more control over each subwoofer is to purchase a Subwoofer Amplifier for each. Regarding the other speakers for your spacious backyard, we recommend adding an outdoor volume control for each pair of speakers and using a DSM4 speaker selector to connect the four pair of speakers connected to the Onkyo with the AMP200 on Zone number 2. Your other choice is to connect the AMP200 to a SSVC4 speaker selector with the Volume Controls built in so you can do your impedance matching while also controlling all four zone volumes from a central location. There is no dedicated center channel pre-amp out for the Onkyo so we’re not sure you will be able integrate it with your second zone stereo outputs. We assume you will just be adding fill when selecting the second zone. You should not experience any latency between the 7.2 surround sound and Zone 2 simulated stereo surround, but that is a question for ONKYO. TL/MA 1819

Is there a remote that controls this unit?

Hi Ian, This unit does not include a remote. However, we do have a 7-zone speaker selector, the ATM-7, with remote. It is a single source, unlike the DSM8. CL/MA 1313

How to connect the subwoofer output from a receiver to this selector?
1 Answers
Hi Henry: Most Receivers only feature Pre-amp subwoofer output which needs to be connected to an external amplifier or a Powered Subwoofer. We would need additional information on what your application, so we can understand why you want to connect your subwoofer to the DSM8. TL

LOVE THIS CONTROL BOX
This is a high quality box and the only one I could find on the market with the A/B input option for each zone. Just hooked it up, but don't anticipate any problems.

Works Great!
The speaker selector arrived quickly as stated. I hooked my speakers up without any problems. The self-adhering button labels were a great addition to help distinguish which speakers each of the 8 selectors control. Sound is greater and unit has solid construction. The size and black color fits right in with my system.
ProsEasy set up Button labels Solid Construction
ConsNone

excellent product!
this speaker selector for 8 zones is terrific! I use it for whole house audio. Controls 16 speakers. It comes with labels to label all the buttons (even thought they are a little small for old people like me to see.) Easy hookup. sound is excellent. only wish it came with a remote to change speaker selection, of course it would be more expensive then. Excellent product for the price, was delivered like the NEXT day after I bought it. Super FAST!
Proseasy hookup.
Conswould be nice to have a remote.

Good Speaker Switch - runs as expected
Good speaker selector, works as expected, low power / heat, I have hooked it up to Four speaker pairs and it works great. I would have preferred better / easier / more rugged connections in the back for the speaker cables... But once it is all cabled up, you shouldnt have to mess with it again. I would recommend this.

This product is great. Not only do you get 8 zones, which holds a lot of speakers, but you also get labels for the zone buttons. I don't have to think about what button goes to what room anymore. I love it!

The input and output ...
The input and output connectors are too small for 14 gauge speaker wire. It will work but it takes some patience as you have to tighten very small screws to keep the speaker wire in place. I had to redo some of the connections many times as it would pop out because the hole is not big enough to accept the wires properly. Once you get past that, the product works as advertised. I just wish they used more standard connectors. Most receivers and amps can be connected within a few seconds. This requires a little patience.

I recently purchased the DSSM 8 zone, dual source selector for our whole house audio system. I was impressed with how easy it was to hook up. The slim profile makes it almost unnoticeable in our pantry. My wife and I are extremely satisfied with how easily you can switch between zones and sources. The support staff was extremely helpful and knowledgeable throughout the order process and had it shipped within a couple days of the order. I have purchased numerous items from Outdoor Speaker Depot and will continue to buy from them. Thanks.
