Unique easy-access impedance matching jumper setting without open the weatherproof seal box. If you enjoy an outdoor audio system, you'll love the convenience of outdoor volume controls! Now you can stop dragging the remote control outside where it is sure to get lost, or avoid having to get up and go to your audio source to turn the volume up or down. This pure resonance volume control offers 300 Watts of optimized sound quality with minimal bass roll-off. Control 1-8 pairs of speakers simultaneously with impedance matching. The autoformer design features outstanding sound quality due to high permeability steel utilization in the volume control core. Comes with Grey or white face plate. In addition, the OVC-300 includes an easy access impedance switch that lets you set the impedance without opening the box.

Tommy • 12/17/2019, 2:17:43 PM how do you wire these up?
Customer Service • 12/17/2019, 2:17:43 PM
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.

Chris • 12/17/2019, 2:17:43 PM This volume control boxes can be installed up or down correct
Customer Service • 12/17/2019, 2:17:43 PM
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. CL
chris • 12/17/2019, 2:17:43 PM 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.
Customer Service • 12/17/2019, 2:17:43 PM
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. TL
Heath • 12/17/2019, 2:17:43 PM 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?
Customer Service • 12/17/2019, 2:17:43 PM
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. TL
Dan • 12/17/2019, 2:17:43 PM What gauge wire are the connectors? Why didnt you use screw type connectors like on your indoor vol control? I will be mounting on 3/4" conduit, doesn't leave much space for making 8 connections and inserting into conduit? Or is intent to push them back into box? I have CL2 14 gauge wire from amp and then to speakers. Wire nuts seem to me mayt take up too much room, maybe butt splice is the answer?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Dan, A direct connection to the circuit board inside the box is more efficient and cost effective than through a connector. If you are going to use the ?-inch pipe, I would suggest using butt splices and electrical tape. You will still need something like our Aqua Blue connectors for terminating the rock speaker, especially if it is to be buried. TL/MA
