The Russound Model 846C Power Supply connects to the status input on the A-CB4iR A-BUS interface module and allows you to take advantage of the System Status feature. Here's how it works: you plug the 846C into a switched AC receptacle, usually on the back of the audio receiver being used. When the audio receiver is turned on, it sends current through the power supply, which tells the green LEDs on the interface module and on the A-BUS volume controls to illuminate, letting you know your system is turned on, even if you're in another room.

  • 110V only; 12 Volt DC 200 mA, regulated
  • dimensions: 2" wide x 2-3/4" high x 1-5/8" deep

Crutchfield Customer Review (What's this?)

Product works just fine but just because they put the Russound name on it doesn't justify the high price. At least Crutchfield had the best price for a new item.

Pros: Works fine with related products.

Cons: About triple the reasonable cost. An alternative can be purchased for a third of the price.

Crutchfield Customer Review (What's this?)

I have a Russound system installed in my home. However, the Russound 846c 12 Volt power adapter was missing. Went on the Crutchfield web site and asked if they had a Power adapter for an AH1 Audio Interface Hub and they came up with the Russound 846c. They shipped it out within 3 days. My system is up and sounds great. Thanks Crutchfield.

Pros: Its works just great. I would recommend Crutchfield to anyone.

Cons: none

A-BUS System Overview


Overview: The 846-C is a12V power supply that provides "status" information to the hub. It plugs into a switched AC output on the back of your system's audio receiver, and sends a signal to the Hub whenever the source is powered up.


  • Input: 117VAC, 60Hz, 7W
  • Output: 12VDC, 300mA Regulated
  • Tip: Positive

A-BUS System Overview

A-BUS System Overview: Instead of multi-channel amplifiers, speaker selector boxes, autoformers, impedance-matching equipment and long runs of expensive speaker wire, A-BUS audio distribution includes amplified in-wall volume controls, and wiring installation time is significantly reduced as only a single 8-connector CAT-5 wire (not included) is run to each location. Simply add A-BUS to your existing stereo/home theater system with an A-BUS Hub and the A-BUS Amplified Controls will provide independent volume and source control to each room where an A-BUS module is installed. Each control contains a stereo amplifier rated to deliver 7.5 watts RMS per channel; the AC current to power each amplifier is delivered via the CAT-5 cable. The system also includes IR remote sensing and retransmission to let you control your components from any of the volume control locations, and included is a remote that controls the volume control itself and can be used to teach the Russound codes to IR learning remotes.
