QUESTIONS & ANSWERS

By Heath from Hillsborough, NC on May 3, 2012
I have an Onkyo TX-NR1007 that is currently driving a pair of AP650 (6 years old and still sound great) on a screened porch via Zone 2. I want to add some RS820OM for a pool area and am thinking about using a set of OVC300 to allow me to control the sound levels differently on the two pairs of speakers. How, exactly, would you wire these in parallel? Run a length of 14/4 from the outputs on the receiver and then split it to go into both OVCs and then from each OVC to the corresponding pair of speakers? What is the best way to split the cables? Or run 2 pairs of 14/4 from the receiver, one to each OVC?
By Customer Service - Q&A on May 3, 2012

Answer:
Hi Heath:

The best way to split the cable is to run a single 14/4 out to the first OVC300. Then using something like our Aqua Blue terminating connectors split the 14/4 with two different lengths of 14/4 so you will need 4 Aqua Blue connectors each with three conductors tied together. Then connect one of the new 14/4 to the first OVC300 and the second one to the second OVC300. From each of the OVC300 connect to the corresponding pair of speakers with two 14/2 speaker cables.You will need two more pairs of Aqua Blue connectors to terminate the pair of RS820OM Rock speakers. Set the Impedance matching to 1/2X on the OVC300. Then set the volume controls to full open (all the way to stop clockwise) for both. Adjust your volume on the Onkyo zone 2 to just below clipping. Note if the amp gets real hot or actual shuts down you will need to change the Impedance settings to 4X on the Volume controls. But looking at the Onkyo TX-NR1007 (a beast) I do not think you will have a problem at the 1/2X setting. We do have 14/2 and 14/4 CL3 rated speaker cable that can be buried as well in 50, 100 and 500 foot lengths. Thank you for considering OSD branded products, good luck.

I have a Onkyo TX-SR 806 I would like to run 4 pairs of speakers off it . Each one with haveing its on volume control. Can you tell me what i need to run this.
By Customer Service - Q&A on January 20, 2013

Answer:
Hi Reggie,
Assuming you mean the ONKYO TX-SR608, your best setup is to go with an external high current power amplifier like our OSD AMP200 (connected directly to your second room pre-amplified outputs). Then add a ISS4 Speaker Selector (protection disabled, turned off) and four of the SVC300 impedance-matching volume controls (set to 4x) one in each zone. With this amplifier, you will also be able to power two pair of speakers per zone off the single volume control. For even more control in the room, select the SVC205 which features a true on/off switch on the front of the face plate. Let us know if you need help in picking out the proper speakers. Thank you for considering OSD branded products.

I purchased a ovc300 I'm having trouble with the volume . I connected the wires on the receiver to the right and left speaker inputs positive to positive and negative to negative then I connected the speaker wires to the input side of the volume control in the same order, then i ran the speaker wires to the two speakers and connected the speaker wires to the output in the same order the two speaker sound don't sound right when I turn the volume up on the ovc300 the one speaker is louder than the other. when I turn down the volume one speaker you can't here at all.
By Customer Service - Q&A on October 19, 2011

Answer:

Volume control are designed to attenuate the sound (turn it down). You have to make sure the output from the receiver/amplifier is properly balanced and set to the maximum comfort listening level. This is when the volume control is turned all the way to the right (fully open with no attenuation). You can also bypass the volume control to make sure you have the balance and volume levels set properly. Also make sure you have set the impedance to 1/2X on the volume control.

By GAMAL from gamal_ferrer@hotmail.com on July 5, 2012
Hello,
I have no experience working A/V equipment and would like to set up some speakers on my pool area. I need some advice on how to complete my project.

- I would like to set up 2 outdoor speakers around my pool/deck area and all want is to be able to connect them to my iphone/ipod.

- I'm trying to stay away from getting a receiver to keep my project simple and on a low budget.

I was wondering if it would be possible to hook up these speakers to a power supply/amplifier and an audio jack? What would I need to get this done?

Any advice?

Thanks for any help!
By Customer Service - Q&A on July 9, 2012

Answer:
Hi Gamal,
To drive a pair of outdoor speakers, you have a couple of options. You could purchase our AMP120, which would be about the same price as the RX4015 (receiver). A less expensive alternative would be our outdoor MA2 amplifier. You could drive our AP450s with this amp and it’s rated for outdoors use. The amp also comes with the cable that goes directly into your iPod and includes a tuner/antenna for radio reception. Keep in mind, however, that the MA2 is only 25W per channel so if you’re looking for more volume, I suggest the indoor AMP120 or indoor RX4105 with a pair of our AP520s or AP640s. You can connect your iPod or computer directly into the back of either of these with an RCA to mini cable.

I have a simple amp with a single set of speaker outputs for left and right currently connected to some deck speakers. I'd like to add some of your green tic/paramount style speakers to and adjacent patio to the same amp. I think I will always want both sets on, however, I would like independent volume control. I suppose if I want one set off I could just turn the volume to minimum. my question is, can I connect in parallel, using wire nuts to create two each left - + and right - + and then run one of each set to 2 seperate volume controls of this model? Then each volume control goes to its own pair of speakers? Is this dangerous for the amp? Or exactly what this device is made for? Is 1/2x setting the same as 2x or is there a discrete 2x setting? Based on other q&a 2x seems appropriate. Thanks, I love all the products to date. Whole house abus system at inlaws using 13 sets of OSD speakers is superb!
By Customer Service - Q&A on March 26, 2012

Answer:
We’ll need to know which amplifier you are already using for your existing speakers. If it is something like our AMP60 or even AMP120, you might have issues loading up two Volume Controls. Does your current amplifier feature a speaker A and B output? If you were using something like AMP200, you could easily use the Speaker A and Speaker B output to a Volume Control, then to the individual pair of speakers. That way you could also turn off either pair at the amplifier as well. The Volume Controls would be set to the 1/2x setting. Also for your new speakers that you want to add, checkout the OMSUB200 combined with the OS525 for a unique Sub-sat system.

By Tommy from georgia on March 24, 2012
how do you wire these up?
By Customer Service - Q&A on March 26, 2012

Answer:
Tommy,
Our voume controls can fit in anywhere between the speaker and the amp or receiver. They have four inputs and four outputs. You would put your speaker wire (like our 16-2 outdoor speaker wire found in the audio/ video cables section ) from the amp/ recever into the inputs of the OVC300 and then out from the outputs to the speaker pair.
CL
By Customer Service - Q&A on March 26, 2012

Answer:
Hi Tommy,

There is a set of wires that come out of the bottom of the outdoor housing. There are four pairs of two-conductor cables: White and Black for input marked left and right and Red and Black for output marked left and right. We offer CL3-rated speaker wire that can be used for direct burial cable as well. Check out the Outdoor Speaker Wire section of the website where we also feature the Aqua Blue connectors or Aqua Red connectors which are weatherproof but not intended for direct burial. These are ideal for terminating the speaker wire from your receiver/amplifier/speaker selector to the Black and White input conductors. Typically you connect a four conductor from your source to the OVC300 and then two conductor to the respective speaker. Lastly, depending on your system setup, you will need to set the switch for impedance matching (1/2x, 4x or 8x). This is accessible through the same hole located at the bottom of the outdoor housing.

This volume control boxes can be installed up or down correct
By Customer Service - Q&A on April 5, 2012

Answer:
Hi Chris,
Yes, you can mount it either way. Just be careful if it's mounted upside down that the hole for the wires is not exposed directly to the elements. You do not want the enclosure to fill with water. If you are mounting it to a conduit or pipe, it should not be a problem.

I am going to buy this volume control. I also was going to purchase some exterior speakers (KB600w) what kind and size speaker wire should I use.
By Customer Service - Q&A on April 5, 2012

Answer:
Hi Chris:

Size or gauge of the wire depends on more of the distance from the source. You want to run 4 conductor to your Volume control and 2 conductor from the Volume Control to your individual speakers. If the total run from your source to your speakers is less than 80 feet than 16 gauge both 4 and 2 conductor will work. For a run longer than 80 feet 14 gauge both 4 and 2 conductor is recommended. Most of the connections you will be making will accept up to 14 gauge including the Volume Controls and speakers. Some people like to run 14 gauge no matter how long figuring bigger is better. All of oiur CL3 speaker wire is rated for direct burial as well. I hope that helps, thank you for considering OSD Audio.

By Ed from Chicago on July 29, 2012
I currently have a 12 year old Onkyo 676 (will use outdoor speakers on speaker B), but may upgrade to 717 soon for the Zone 2/Zone 3 capabilities (would use outdoor speakers on those additional zone speaker outpouts). We're looking at this volume control (OVC300) to control the volume for two pair (4 total) RS840 rock speakers. The distance from receiver to speakers would be 50-70' depending on which speaker.

To minimize wires, would it be acceptable to run 14-4 from the receiver to the OVC300 (for Left/Right), and then 14-4 from the OVC 300 to an ISS4 (again for Left/Right), and then (4) 14-2's to each speaker? Or would the ISS4 not be needed if we always want all 4 speakers on, and when we run the 14-4 from the OVC300, instead of to the ISS4 we would just run them in paralell by connecting 1/2 of the 14-4 to (2) 14-2's, and the other 1/2 of the 14-4 to the remaining (2) 14-2's?

Thanks in advance!
By Customer Service - Q&A on July 31, 2012

Answer:
Hi Ed,
You would just wire the two sets in parallel to the OVC300 and you would not need the iss4.
CL
By Customer Service - Q&A on July 31, 2012

Answer:
Hi Ed,

Plus it's a good idea to run 14/4 CL3 speaker wire from the receiver to the OVC300. Then use 14/2 from the OVC300. You can terminate the four conductors coming from the OVC300 or run a two conductor to the first pair of speakers. You could then terminate the incoming from the OVC300 to two more dual conductors (one for left and a second pair for right). Either way will work.

Perfect for some
March 11, 2014
The case is solidly built however it is only designed to be mounted in one orientation. The wires must come in from the bottom. Perfect for around a pool where your wires may be burried in the ground but not as good if you're mounting your speakers on a house where your conduit would be traveling upwards. This could be an easy fix if you could remove the control from the housing but I couldn't get it out. My other big complaint is that the connections are made with pigtail wires that come out of the housing about 6-8 inches. This forces you to make 8 splices inside the conduit. That's a bad design. Again if you could remove the control from the housing you'd be able to connect the wires directly to the terminals. There is no room to tuck the pigtails back into the housing so it will be hard to service in the future. For this reason I suggest soldering the connections.
Merchant Response:
Hi Chris, To address some of your issues: The volume control can be detached from the housing, you simply need to pop the knob off and unscrew the bolt first. The housing can then be flipped upside down to have the conduit facing upwards.
Pros:
Nice finish Great price
Cons:
Pigtail connections Control doesn't separate from housing Housing is only designed to mount with conduit below housing Can feel bass notes inside the volume control.

Solid, Nice Looking. Performance Questionable
September 16, 2013
I wasn't paying attention apparently as I didn't realize it wasn't made for wall mounting. Probably due to my excitement over finding a control that had wires for connections rather than the flimsy little push in or screw on connections on most that continually fell off. I just took the guts out and installed them in a standard box then screwed the cover to the stucco. Its looks really nice. It's build very solid and looks it. However, the connection wires I was so excited about can't be more than 18 gauge. They may be even smaller. this is a huge disappointment since I ran 12 gauge speaker wire as I have a fairly long run and didn't want any loss of fidelity from this. On top of that, the color coding of the wires is absolutely ridiculous making it very tedious to make sure the connections are right. While the colors may not have been the same as my speaker wire the killer is that the color in isn't even the same as the color out. There are essentially 8 wires each with it's own color or color combination. I'm driving a pair of killer JBL night club speakers on my patio using a dedicated Integra 125W per channel power amp hooked to a Proceed AVP controller. At worst they sound awesome and can really blow the roof off. Well, that was when I didn't have the volume control and just had the wires spliced directly and controlled things from inside. The speakers still sound good but, even with the pre-amp and power amp set to max you have to turn the patio volume control to max to hear them at a middle volume. Until you've turned the volume control knob 60-70% of it's limit there's no sound at all. I installed the new power amp for the speakers at the same time. To be sure it's not the amp I did a direct connection test to my audio system speakers and they shook the house. Prior to this I was using a Pioneer VSX-522-K receiver to drive them (a big wasted of electronics). I can't say for 100% certainty the problem is caused by the volume control yet. I'm going to remove it and put the direct connection back in place and see if it goes back to what it was before. Once I've done that I'll post the results here. As for the question below regarding recommending to a friend, it would depending on his application. In the right situation this would be an excellent switch. in mine, it's definitely not the best solution.
Pros:
Build quality of case. Appearance. Weatherproof. Wired connections allowing any size speaker wire to be used.
Cons:
1. Super small gauge wires making it a waste to buy decent speaker wire. 2. Color coding a pain in the .......
Best Uses:
Outdoors since it's pretty much weather proof. Actually made foe sitting on a conduit not wall mounting so consider that.

This control switch is very impressive in person. It's built very solid, is easy to install, and provide a great option to managing the volume without stepping back into the house. I installed this switch on my back patio, attached inverted from the pictures on this site, with 3/4" PVC leading from the port through the ceiling for concealing/protecting the wiring. The instructions are slim, but provide all the information you need to get this wired up and working on the first try. I was very impressed and I'll definitely be recommending OSD to my friends.

Good Volume Control
April 5, 2013
Product works as advertised. A slight word of caution. The units show as being able to handle more than one set of speakers to a source. This is true however a controller is required for each set of speakers, more than 1 set of speakers can not be wired to an individual controller.
Pros:
Works well for my purpose.
Cons:
Would like a 'volume off' at the lowest setting. I know there are version that have this capability, but nothing that is directly comporable to this unit.

Very Solid, Works as Expected
July 22, 2012
The product was very solid and works just as I hoped. It was easy to install just as any pvc electrical devices, however the box was not designed to open by the user, therefore you had to make the splices then slide them up into to feeding conduit, which prevented the gluing of the conduit to the box to allow future maintenence/access. So, if you wanted to glue it you would need to add a junction box immediately adjacent to it for access to the connections, not an attractive fix but it would be the only way to solve the issue. Overall I would reccomend the product it performs as advertised. The delivery to VA was about 4-5 days.
Pros:
Worked as expected, Very High Quality, Low Power Consumption, Quality Construction, Easy To Use
