VOL85 SeriesOwner’s Manual
Thank you for purchasing this Rockville V0L85 Series Wall Volume Controller. Please read this owner’s manual carefully for proper use. Should you need technical assistance, please call our helpline at 1-646-758-0144, Monday through Friday, 9 am to 5 pm EST.
The V0L850 and V0L855 are wall-mounted volume controllers that work with any standard home audio or pro audio system that operates with 4-8 ohm speakers. Our volume controllers are some of the best on the market. The reliability and accuracy is what make a big difference. These 12 step controllers are precise and accurate. They support speakers connected to them that add up to 50 watts RMS or less. If you already have a multi-zone amplifier then you can go out from any zone and into this volume controller and then out from the controller into The speakers (each speaker is wired from one to the next in parallel). The end result is that you can access the volume control from that room without having to change the volume from the amplifier itself.

- If an enclosed box is to be used, we recommend a deep box (3.5 inches in depth).
WIRING VOL850
WIRING 855
The V0L855 features an impedance matching switch which will allow matching your amp’s minimum impedance regardless of the number of speakers you use and their final impedance. For example, if your amplifier has a minimum impedance of 4 ohms and your speaker’s final impedance is 2 ohms, the impedance switch should be set to 4 ohms.
