OSD Audio's SVC300 is an impedance-matching volume control that lets you adjust the volume of a pair of speakers independently of other speakers within a whole house audio system. Ideal for areas such dining or conference rooms where you may want softer volumes or for saunas or garages where you may want higher volumes, the SVC300 maintains the full hi-fi audio frequency response with no low frequency roll-off. Equipped with the same features of volume controls that cost twice as much, the SVC300 is rated at 300 Watts peak and includes adjustable jumpers to add up to eight pairs of 8-ohm speakers simultaneously. The impedance-matching feature helps stabilize the ohm load going back to the amp or receiver to avoid overheating and damaging expensive equipment. A complete volume control kit that fits into a standard single-gang box, the SVC300 also includes the junction box, screws and assorted color trim plates (white, ivory and almond) so you can choose the color that best matches the room. This versatile whole house volume control is compatible with almost any dedicated audio zone or whole house system, and the 12-step rotary knob adjusts the volume from inaudible to loud and everything in between.

Features:
  • Decora style impedance-matching volume control for whole house audio systems and dedicated audio zones
  • Rated at 150 Watts per channel with minimal bass roll-off
  • Impedance-matching feature stabilizes the ohm load so parallel connections of multiple volume controls can be installed without damaging the amplifier
  • Front-mounted adjustable jumpers allow easy adjustment when multiple pairs of speakers are connected to a single receiver or amplifier
  • Accepts up to 14-gauge wiring and fits in a standard gang box with a depth of 2.9'Includes junction box and screws as well as white, ivory and almond trim plates to match any room d'cor
  • Precision electronics provide low distortion and a ruler flat frequency response
  • 12-step linear rotary-style knob for a wide range of listening volumes
  • Installs easily and works with almost any audio system 

What Is Impedance Protection?
Speakers are specified by impedance, which is a measurement of resistance to alternating current, and a common value for speakers is 8 ohms. When you're connecting multiple speakers to a receiver or amplifier, you need to stay above the amp's minimum load requirements because going below the impedance rating can overheat or even damage expensive equipment. The SVC300 allows you to match the impedance with the number of speakers being controlled with the capabilities of your amp. A basic multi-room system will typically have an amplifier/receiver, a speaker selector, four to eight pairs of speakers, and volume controls. Impedance-matching volume controls feature three settings depending on how many speakers you are connecting. For one to two pairs of 8-ohm speakers, the setting is 1/2x; for three or four pairs of 8 ohm speakers, the setting is 4X. Keep in mind that volume controls do not add gain (volume) to your speakers but simply attenuate the volume up or down. During setup, you'll set the source volume to its optimum level, then the volume control turns the sound down to inaudible levels.

What's on your mind?


Drew • 12/17/2019, 2:17:43 PM I have a long speaker cable run to this control for my outdoor speakers about 60' so I am using 12 gauge speaker wire. Will I be able to squeeze the 12-gauge wire into these connectors or will I have to add a junction box and splice the 12 gauge down to 14 gauge wire? I would like to not have to splice down the cables obviously, but it looks like there are no speaker controls that can accommodate 12 gauge wire. Thanks in advance.

Drew, This is made for 14 gauge max. Most customers thin the wire down to accommodate that large of speaker cable. CL
John • 12/17/2019, 2:17:43 PM I have a Lafayette stereo receiver rated at 150watts with your typical speaker A,B A&B combinations. I have 2 indoor speakers already hooked up. I have installed (2) Polk Audio RC80I speakers installed outside under the eave. Is the SVC300 the proper switch to use? And if it is, what setting would I use on the switch itself? Appreciate your help...Thanks..
Customer Service • 12/17/2019, 2:17:43 PM
Hi John: I am assuming you mean a stereo pair of speakers on the inside connected to the Speaker A output and you are planning to use the pair of Polk In-Ceiling Speakers connecting them to the Speaker B output. The SVC300 will work fine if you are planning to mount the switch in the wall in the interior of the home. We do have outdoor Volume Controls as well. So one pair of 8 ohm speakers inside and a second pair of 8 ohm speakers outside, is that about right? Question are you planning to connect a volume control to the inside pair as well or are you just wanting to control the outdoor speakers with the single volume control. In this setup the Volume Control would be set to 1/2x the same it would be set to if you had a second volume control connected to the inside speakers. I might suggest our SSVC1 table top volume control which features both a on/off switch and Dual source A/B switch. You could step up and use our SSVC2 and connect both the inside speakers and outside speakers. It all depends on how much control you are looking for and how accessible you are to the speaker wires. We do offer our CL3 speaker wire which works for both in-wall and outdoors including direct burial. You can buy either 4 or 2 conductor (16 or 14 gauge). 4 Conductor would be used from the Receiver to the Volume Control or Speaker Selector than use 2 conductor to each speaker. Please let me know your exact setup so I can be of more help. TL
Alex • 12/17/2019, 2:17:43 PM would you recommend an appropriate impedance volume control for my speakers- a pair of klipsch R-1165-C 11 to be connected to Denon AVR-2113 CI Thanks
Customer Service • 12/17/2019, 2:17:43 PM
Hi Alex, The SVC300 would be a good choice. It features a rotary knob to control the volume. We do offer a slider-style version as well, the VMS300. TL
Dave • 12/17/2019, 2:17:43 PM it states this is to be mounted in a single gang box, but can it be used in a 3 gang box with other decora switches?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Dave, Yes, you can mount it in a double- or even triple-gang box with other components. TL/MA
Cerys • 12/17/2019, 2:17:43 PM What is the dimension of the volume control and is there a matching base box available as well? Thanks!
Customer Service • 12/17/2019, 2:17:43 PM
Hi Cerys, The in wall SVC300 will fit in a standard single gang box. We have the OVC300 that has a complete box type housing primarily for outdoor applications but can be adapted for indoor use. CL Dimensions are: SVC300: 4.125cm W x 6.35cm H x 6.35cm D OVC300: 7.25cm W x 11.43cm H x 8.25cm D
