Features & Specifications

Speaker selectors that enable you to connect multiple pairs of speakers to your stereo receiver or amplifier and then set the volume of any pair independently include the Speaker Selector 4 Pair High Power OSD-ISS4 available at Outdoor Speaker Depot. OSD Audio offers the ISS Series of low profile speaker selectors to control audio in four zones. On/Off switches for each zone are included so one signal can be distributed to four different listening zones. The OSD-ISS4 Speaker Selector handles 140 watts per channel total input power without the manual protection engaged, and 70 watts per channel with the protection engaged. You can listen to one or several speakers at one time. A single amplifier can power several pairs of speakers with the included impedance protection. The ISS4 comes with a five-year warranty.

Ugraded Model with Improved Input/Output Connectors!

The upgraded, European-style removable input/output connectors give you 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 ISS4 combines with other 8.5" wide OSD Audio components (which will be available in the future) to make a standard 17" wide unit.

Specifications

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.

The manual power protection switch engages 10 ohm /15 watt resistors wired in parallel, three per channel in the ISS8 or two per channel in the ISS6/ISS4 providing higher power handling capability than the competition (able to handle up to 50% more power!) in order to protect your amplifier. All ISS’s are capable of handling 140 watts per channel total input power without the manual protection engaged and 70 watts per channel with the protection engaged.

The better screw in terminals 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 ISS4 combines with other 8.5" wide OSD Audio components (which will be available in the future) to make a standard 17" wide unit.

QUESTIONS & ANSWERS

By win from Australia on September 22, 2012
Hi.
I am using this with zone 2 output of my onkyo 609 for two pair of speakers (bed room and patio). Onkyo says 6 ohm minimum. The speakers are 8 ohm. Is this all right with this set up ? Would it sacrifice any quality, volume etc? Thanks
By Customer Service - Q&A on September 24, 2012

Answer:
Hi Win,
The Zone 2 you’re referring to is intended for a pair of speakers. Ideally, for 4 more zones you would add an amp like our AMP200. What you could do is hook the ISS4 up with what you have now and see if the Onkyo is giving you enough power and go from there. You may notice when playing more than one pair at a time you have less volume capability. In this case you could add an amp. All the components we sell are 8 ohm so they will work fine with your Onkyo receiver.

Can you use this with the SVC300 inwall volume controls handling the impedence matching with the Single Pair Direct Switch in the off position?
By Customer Service - Q&A on January 29, 2013

Answer:
Hi Dave,
If you are using a speaker selector and volume control, let the volume control do the impedance matching and turn the protection off on the speaker selector.

By John from Chatham, MA on November 5, 2011
Will this device control speaker pairs that have different impedance levels? I have one pair of speakers that are rated 6 ohms and the other pair is 8 ohms.
By Customer Service - Q&A on November 7, 2011

Answer:
That should not be a problem. I am assuming you will be connecting more than these two pairs of speakers to the four zone box. If so, just make sure the internal protection switch is enabled (on). If you are adding impedance-matching volume controls between the box and speakers, then defeat the internal protection.

By Vinay from Dallas on May 21, 2012
Hello:

I am looking to connect 3 pairs of "Polk Audio RC80i 2-Way In-Ceiling Speakers". Would it be possible with this?
2. I have been recommended to get this "Russound SS-4.2". Instead, I am planning on getting this item. Am I missing anything or will this item suffice what the SS4.2 is supposed to do.

TIA!
Vinay

Hi Vinay,

The Russound piece is an excellent unit. It does have a nice feature that has protection for your amplifier/receiver; otherwise they are similar. I am partial to our DSM4 which is the next step up and adds dual source (switchable per zone), a European style removable input/output connector and a brushed aluminum faceplate for cosmetic appeal. All three will take care of your application.

I have 12 guage wire for a long run to outside speakers. Will thsi handle this thick of wire?
By Customer Service - Q&A on April 2, 2012

Answer:
Bob,
The Iss4 accepts up to a 14 gauge wire, sometimes installers will thin the end of the larger wire down to fit into the terminal.

By Scott from Utah on December 1, 2012
Can this ISS4 be safely used as an amplifier switch -- i.e. used in reverse -- if the impedance protection circuit is disabled?
By Customer Service - Q&A on December 6, 2012

Answer:
Hi Scott,
The ISS4 speaker selector should work as long as the protection button is disabled. Our ATM7 speaker selector has the two-way feature. This unit is dual source with 7 outputs or 7 sources with 2 outputs.

By Gerry Brostek from nyc on December 8, 2012
I am looking for a selector that will handle only 3 sets of speakers. I am afraid if I use a 4 set model and just leave the 4th one off all the time, that power will be directed through resistors to maintain impedance, and just waste electricity. Does that happen? I leave all 3 sets on 24/7, I really don't use the on/off buttons ever. I'm just trying to balance the impedance of 3 sets of 8 ohm speakers.

Is this unit going to make me happy or should I look elsewhere?
By Customer Service - Q&A on December 11, 2012

Answer:
Tim: Hi Gerry,

The lack of a fourth speaker should have no effect since you have an on/off switch for each zone and would just leave the fourth zone in the off position. Our updated ISS4 also comes with removable input/output connectors that provide improved connectivity. Just remember to keep the protection switch in while you are playing the three pair 24/7. It certainly will be an improvement over your previous selector.

By gerry brostek from nyc on December 8, 2012
If I use the ISS4 and I DONT engage the protection circuit, and I run 3 sets of 8 ohm speakers, what impedance will my receiver see? And if I DO engage the protection circuit, what impedance will my receiver see?

I am trying to upgrade from a crappy RADIO SHACK unit. It worked fine with no bells or whistles and no overload circuit, and never had any problems. However, the switches were sketchy and wore out quickly. Im looking to buy a unit and leave all 3 sets on 24/7.
By Customer Service - Q&A on December 10, 2012

Answer:
Hi Gerry,

Most of the early designs of speaker selectors had some sort of automatic protection in order to work long term. It prevented units from coming back from customers who did not understand the importance of using the protection switch when playing two or more pairs of speakers. I'm not sure you are going to notice a big difference from 3 to 4 zones. You could use independent volume controls for each zone (if your wiring is accessible) or purchase either our AMP200 or AMP300 and connect the three 8-ohm pairs in parallel so you have a 2.6-ohm load. This way you'll get the most out of the amplifier while not cutting half the power by adding the resistors in-line in the speaker selector. It would help to know what speakers are you using, what kind of amplification you have and and how old it is.

I currently have a swithc that is providing Cross over between the various zones. Does this swich provide any cross over protection?
By Customer Service - Q&A on November 29, 2011

Answer:
Stephen,
This speaker selector has Impedance matching.
CL
By Customer Service - Q&A on November 29, 2011

Answer:
I am assuming you have a switch now that separates your zones but with no actual dedicated protection. The ISS4 Speaker Selector has a protection switch on the front that we recommend keeping enabled or in the on position (pushed in) whether you are playing 1, 2, 3 or 4 pairs at a time. The only time you would defeat the switch would be if you were using Impedance Matching Volume Controls, one for each pair of speakers. Having both the protection circuit enabled plus the Impedance Matching Volume Control would cause a conflict with the Amplifier/Receiver

By Harry from UK on April 10, 2012
Would I need anything other than a normal amplifier and passive speakers to use this? Would I need impedance matching volume controls, whatever they are?
By Customer Service - Q&A on April 10, 2012

Answer:
Harry,
The ISS4 already has impedance matching so you can use a resitor based volume control if you would like to add that in. Take a look at the VKR120.

Performs as described
March 4, 2016
Compact size and has a quality appearance. I have 3 pair of 8ohm indoor ceiling speakers and one pair 4 ohm outdoor speakers connected to a 40 W stereo receiver. Works great for selecting any or all zones. Owned for one month so far ans works fine. Excellent price for product. Shipped quickly.
Pros:
Price, size, and easy to use.
Cons:
Wire connections are tiny and not as described in manual. Would be great addition to include a tool (very tiny screwdriver) to make wire connections.

This replaces one I bought from Radio Shack about a dozen years ago and which was becoming squirrelly. Since hooking it up, which was a little fiddly, it works just fine and the little labels that come with it (to identify the speaker zones on the selector buttons) are a nice touch.

I wired my entire ground floor of my house for in ceiling speakers. I purches eight kevlar speakers and two selector switches. Now when I have guests over there is a party in every room. Everything works great and the switches were clearly marked. The package was packed well for shipping. The only flaw was their tracking of my package was no working. I called and they could not tell me where my package was. But, my package did show up on my door step three days later. No harm no foul.
