Features & Specifications

The OSD-ISS6 Speaker Selector High Power 6 Pair available at Outdoor Speaker Depot will allow users to run as many zones as they choose at a given time, whether it's running all of them simultaneously or deactivating some and running speakers in just one or two zones. Individual On/Off selectors for every zone distributes one stereo speaker-level signal to eight, six or four stereo listening zones. You can run 140 watts per channel total input power without engaging the manual protection, or 70 watts per channel when the protection is engaged. With the OSD-ISS6's impedance protection, one amplifier can safely power several pairs of speakers. The OSD-ISS6 Speaker Selector High Power 6 Pair comes with a warranty good for five years. Order today from Outdoor Speaker Depot and get fast shipping.

Ugraded Model with Improved Input/Output Connectors!

The upgraded, European-style removable input/output connectors offer better leverage when terminating cable and accept up to 14 gauge cable. The ISS’s feature 16 gauge steel construction with our durable black wrinkle powder coating and gray silk-screening. Each unit is provided with an in-depth instruction sheet and die cut labels that fit the recessed area on the buttons for labeling each zone. The 8.5" chassis width of the ISS6 combines with other 8.5" wide OSD Audio components (which will be available in the future) to make a standard 17" wide unit.


Other Product Info

The ISS4, ISS6 and ISS8 are low-profile speaker distribution systems with individual on/off selectors for each listening zone which distribute one stereo speaker-level signal to eight, six or four stereo listening zones. The ISS Series also provides manual power protection that is activated from the rear panel.

With respect to the ISS6, I read that you can control the volume for each pair of speakers separately. How can that be done? It doesn't appear to have individual volume controls... Awaiting your response.
1 Answer
Hi Steve: Good question, that bullet point is incorrect, you can not control the volume per zone unless you add a volume Control for that zone. And if you are adding Impedance Matching Volume Controls to protect you Amp/Receiver then you must add a volume control for each zone and the impedance matching setting must be the same on all 6 or for however many zones you have connected. Of course, you can select the SSVC6D which has the internal volume control built in for each zone plus an on/off switch per zone the same switch as the ISS6. Thanks for pointing out the bullet point.

Currently, I have 3 pairs of speakers I would be controlling with this selector switch. 2 of those pairs of speakers are labeled as being 8-ohm impedance. However, the 3rd pair of those speakers is labeled as being 6-ohm impedance. Eventually, I will be adding 3 more pairs of 8-ohm speakers for a total of 6 pairs. Would I be risking my amplifier by using those 6-ohm speakers with this selector switch?
1 Answer
Hi Ken: It sounds like you are not using or intend on using impedance matching volume controls for your current 3 pairs or the three pairs you plan on adding. You can add the 3 pair to the ISS6 but if you depend on using the internal protection you cut the power handling per channel from 140 Watts to 70 Watts per channel. If you are not planning on using external external Impedance matching Volume Controls (you would need one for each zone) then maybe the SSVC6D would be a better fit. It features six Internal Impedance Matching Volume Controls. The Volume Controls do a better job at Impedance Matching than the protection circuit found in the ISS and DSM series speaker selectors. Another option is the TSM8 Speaker Selectors which features the best internal protection. It has a selectable protection switch based upon how many speakers you are actually using. Good luck TL/4835

October 30, 2017
Do you have any speaker selectors that would allow 12 gauge wire? They all seem to fit up to 14 gauge only. I have some long runs for outdoor speakers - including one that's 150 ft long and had heard that a larger gauge would be better so I ordered(and just received) a 500ft spool of 12 Gauge 2-conductor Oxygen Free Burial Rated In-Wall Speaker Cable 500ft CL3 but now I'm seeing that it's too large for speaker selectors...
1 Answer
Hi Daryl: The only Speaker Speaker selector that accepts 12 gauge wire is our ATM7. The only issue with the ATM7 it has no internal Impedance protection built in. We recommend using Impedance Matching Volume Controls but those have an issue with 12 gauge as well. I usually recommend 16 gauge up to 80 feet and 14 gauge up to 200 feet with 112 gauge over 200 feet. Unless it is Low Frequencies like for a sub woofer then we are talking 14 gauge to 50 feet and 12 gauge above that. Sorry about that TL/4616

from Frisco Texas asked:
August 10, 2017
I have four outdoor 8ohm speakers to wire. Do I wire one speaker to the R+ and R- contacts in the Output 1 area and then the 2nd speaker to the L+ and L- in Output 1? Then the other two speakers would be in the Output 2 area with the 3rd wired to R+ and R- of Output 2 and the final speaker #4 would wire to L+ and L- Output 2? So all four speakers would wire to the block of Output 1 and 2? Hope that makes sense.
1 Answer
Hi Frank: This is a six zone speaker selector but you only mention two pair of speakers and nothing about possible Volume Controls. Pretty much you unplug the Zone1/Zone 2 Connector and connect as you described. Speaker 1 connect to R +/-, then the second speaker to Left +/- and the same with speaker 3 and 4 connecting to R&L +/- of the four inputs on the same connector labeled Zone 2. I am assuming your are running the four speaker as two stereo pairs. And do you need six zones for just two pairs. And what are you planning for your sources? You can supply me with more information like the rest of your system including Brand names and model numbers. My contact info: so I can answer any additional questions.. Good luck TL/4516

April 28, 2015
This product has two selection source for the six pair of speaker. Is there any option to have added to the main source, a local source ( for example: input to connect cellphone music library) for each one of the six room ? Is it required a wall plate amplifier in the input for a local source ( able to connect cellphone music library) ?or am I able to add just an wall plate connector straight in the local source ? What product you guys suggest for this kind of configuration ? Thanks in advance and sorry about the possible weird question.
1 Answer
Hi Daniel, This is a passive device which requires an amplifier to run power through to the speakers. The speaker selector just allows you to separate that power into different zones. Only one amp can connect to this model, but two amps can connect to the DSM6 and SSVC6.

1 Answer
Hi Vincent, In theory it's possible, but really it depends on how many ohms your receiver can handle. If it only states that it runs at 8ohm, it would be risky to run anything more than a single pair of speakers off it. If it can run at 4ohms, you have a better chance. Typically multi-zone audio should be run off a high-current amplifier such as our AMP300 or a multi-zone amp such as our MX1260.

Hi Robert, Check out our DSM6 Dual-Source, 6-Zone speaker selector with impedance protection. This will allow you to run 6 pairs of speakers, 1 on each zone and you can run 2 sources into the unit, allowing you to split zones amongst the sources.

from Toro asked:
August 22, 2014
Hello, I'm thinking of using the selector for a different purpose, and would appreciate any advice. I live in a rowhouse and have a small 5.1 system (Samsung ht-f6530). I can't always have the subwoofer on (even at the lowest setting). Could I run all the 6 speakers through the selector, and turn them off as needed? I would then have control on each of the speaker and keep my neighbors happy. Thank you, K
1 Answer
Unfortunately that will not work. The home theater receiver has outputs for each speaker. The Speaker selector only has one input for source. On top of that, the receiver can only handle one speaker per output. Running all speakers off one output like that would damage your components. Call us for recommendations.

With this unit - can you have multiple zones selected at one time? For an example, zones (1) and (2) at one time or does the unit allow (1) to be pressed at one time.
1 Answer
Hello, Yes. The ISS6 will allow you to run as many zones as you want at any given time. You can run all at once, or you can choose which ones to have running while the others are deactivated. Just make sure that you are running a proper amp for that many speakers. You don't want to run a receiver. Check out our AMP300 for an example of what type of amp is needed to run this type of load.

July 31, 2013
I am currently using this switch with my Sonos Connect Amp for three sets of hard wired speakers. I would like to add the Outdoor Rock Speakers with the WR150 Connected to one of the switch positions. It looks as if I can connect usibg an RCA type cable making sure that I stay within wireless transmitter range restrictions. Do you see any problems?
1 Answer
HI Randal: The WR-150 Wireless Speakers will not work with the OSD-ISS6. The Transmitter only has an input (no output connection) so once it is connected to a source it transmits to the main speaker which features an internal Wireless receiver and also Power Amplifier. A second satellite speaker is connected by a speaker wire. We have any number of Rock speakers but they need to be hard wired back to the speaker selector. Sorry about that TL-2113

Will this unit work without connecting a 2nd amp, if I have an Onkyo TX-NR709 Av receiver, it has a zone 2 option. Looking to have 6 zones of music thou the house. with some builder grade speaker or a step up. Thanks Eric
1 Answer
Hi Eric, Typically with multi-rooms, the receiver alone is not enough power to run your surround sound and 6 additional zones with the "Zone 2". Most customers add an amp to power the whole house. After reviewing the extensive manual for your Onkyo receiver, you'll notice on page 63 it talks about Zone 2. You have two options: powered utilizing the 110 Watts per channel that was intended for Channel 6 and 7 of a 7.1 system. This will work if you were planning to run a single pair of speakers for the second zone. But in the case where you want to connect up to six zones, we would recommend utilizing the signal level preouts for Zone 2 to connect to a High Current external amplifier like our OSD AMP200. Then you can use a speaker selector like our ISS6 or DSM6 to control the 6 individual zones. Each of these speaker selectors features switchable protection. Ideally, you can add an impedance-matching volume control for each zone as well. This features more control in each zone while providing a better way to protect your system than the internal protection of the Speaker Selector (which you would disable). Note we also offer a large selection of Custom Install speakers for both inside and outside in all different shapes, sizes and price ranges. Please let us know if this information helped. CL/TL

ISS^ High Power 6 Pair Speaker Selector
I was looking out for a switch to control my Inbuilt speaker. Luckily I found this item at OSD which was exactly the same I was looking for. To my wonder it worked very well & sound of speaker also improved a lot without any over loading problem.Excellent quality for the price I paid. I order one more with volume control from OSD. It would be even better if they can give RCA connector for input source instead of screw type connector for ease of connectivity.
ProsEase of speaker connection & set up.
ConsScrew type connector for input source.

Simple, Elegant, Functional Design
An excellently designed piece of equipment. It handled my connections perfectly! A simple, elegant design and easy to make the connections, including screw in sockets. What a pleasure. A nice added touch were pre-printed, stick-on labels that match the speaker locations (e.g. Mstr Bdrm). Through-power is substantial.

Overall works fine. Good value. I am not to crazy about the new wire attachment. It is a modular / removable attachment and I had a lot of difficulty attaching thicker grade wire. It was difficult to attach the wires securely They kept coming off. Was very frustrating. I get the concept but needs to be redesigned.

Exactly what I needed at good price
Needed this item to direct music to multiple areas of house (i.e. garage, patio, kitchen, etc.). Found it to be very simple to connect for even a novice - just strip wires and plug em in. Really like the fact that its not just music to one area like some other switches. Not really for use with surround sound systems. Word of caution to those with receivers/systems that use proprietary wiring for connecting their speakers & sub - you may have to get creative with your wiring (or just use a different receiver).

Still a Good Simple Speaker Selector
After a month of use my original review still stands. This is a great speaker selector at a great price. Just updating my review as a certified buyer now. Works great as a whole hose audio zone selector. Pros: - Built in impedance protection (button pushed in for on). But not necessary if you have impedance matching volume controls properly setup. - Small for factor and does not require any power - Enough space between speaker connections to prevent shorting wires Cons: - Not rack mount ready. Its the right with, but no brackets and you would have to drill and tap the housing. No problem to remove the housing to do that, or to just use a shelf. but would of been nice if they had it already drilled for brackets. - I wish they had an A/B model of this selector.
