Drive your multi-room system

AudioSource's AMP800VS gives you options for powering your whole-house audio system. It's perfect for music in the bedrooms, the kitchen, and the dining room — all at the same time. It's flexible, too. Play the same source through all four zones, or play a different source in each of your rooms.

Great for indoor and outdoor speakers

Power up to four pairs of speakers simultaneously for music indoors or out. The '800VS delivers 40 watts per channel at both four and eight ohms. Need more power to drive your patio or floor-standing speakers? Bridge two channels together and get a robust 80 watts per channel at eight ohms.

Versatile inputs and outputs

Each zone also has a dedicated pair of RCA inputs to play a connected source through a single zone. Want to expand your multi-room system? Use the RCA outputs to daisy-chain two amplifiers together and play the same source through both.

Multiple power-on options

Use the front-panel power button to toggle the '800VS on and off. It can also turn on automatically when it detects a source. 12-volt trigger compatibility makes for flexible system configuration. It lets the amp turn on when another piece of equipment is fired up.

Product Research


AudioSource Amp Series: AudioSource AMP series amplifiers are designed for home and commercial audio distribution systems where high quality sound, flexibility, and reliability are essential. The AMP series offers exceptional value and many features that will make their installation and use easy and convenient.

8 Channel Amplifier: The AudioSource AMP800VS employs a Class A/B amplifier design with 8 channels of amplification that can be used in a Stereo (4 to 8-ohm) or Bridged (8-ohm) configuration.

  • Stereo (8-ohm): 40 watts x 8 channel, 20-20kHz, <0.2% THD+N
  • Stereo (4-ohm): 40 watts x 8 channel, 20-20kHz, <0.2% THD+N
  • Bridged Mono (8-ohm): 80 watts x 4 channel, 1kHz, <0.2% THD+N

4 Zones: The 8 channel power amplifier is divided into 4 Zones. Each Zone can consist of either a pair of speakers in Stereo or a single Bridged mono speaker.

2 Bus Inputs/Outputs: The AMP800VS has two common or BUS inputs that receives audio signals from standard line-level audio sources and sends them to any or all channels. The BUS line outputs are direct feed-through to allow the BUS inputs to be fed to other amplifiers.

8 Independent Channel Inputs: All eight channels of the amplifier have their own dedicated input that allows the connection of audio sources in addition to the common BUS inputs.

Phoenix-Style Speaker Connectors: The AMP800VS uses high quality Phoenix-style connectors for the speaker connections. Use 14-18 gauge stranded two-conductor loudspeaker wire.

Channel Gain Control: Each channel has its own independent level adjustment on the back of the amplifier. This allows the output level of each speaker to be perfectly matched to its area. It can also be used to limit the maximum audio level in a certain area.

LED Status Indicator Lights: Each pair of channels or zones has a bi-color LED to indicate its operational status. A Blue light indicates normal operation, a Red light indicates that the amplifier's protection circuitry has been activated, and no light indicates the unit is in standby mode. These indicators provide quick and easy troubleshooting of the system.

Power On/Off Modes: The AudioSource AMP800VS offers 3 Power On/Off Modes - Manual, Auto, and Trigger.

  • Manual: In this mode, you can simply turn the AMP800VS On or Off by pressing the Power button on the front of the amplifier.
  • Auto: Set to Auto for signal sensing, which allows the amp to turn on when an audio signal (>5mV) is detected at one of its inputs. The front-panel power switch must be in the On position (pushed in) for the Auto feature to operate. When there is no audio signal present, the amplifier will return to Standby mode after 15 minutes.
  • Trigger In/Out: The 12V trigger input and output allow the AMP800VS to be powered on by other electronics or to power on other electronics via a 3.5mm minijack cable. The trigger input can operate with voltages between 3 and 30VDC.

Protection Circuitry: If the amplifier's protection circuitry determines that a channel must be shut down due to excessive heat or low impedance (a short), only the channels that are affected will be turned off.  The remaining zones or channels will continue to operate. Once the condition has been corrected for the zone or channel in question, audio will be output again.

Mounting Options: The AudioSource AMP800VS power amplifier features four rubber feet and can simply be placed on top of a flat surface; like a table-top, shelf, or stand. You can also remove the four rubber feet and rack-mount the amplifier using the included rack-mount ears and screws.

Customer Q&A

6 questions already asked

Can this amplifier run on both US and EU voltage ie 110 and 220 Volt ?
jacob  Aug 12, 2023
1 answer
This AudioSource AMP800VS is capable of operating with both US and EU voltage, Jacob. The unit is set at the factory for 115V U.S. operation. For 230V operation, move the voltage selector switch to on the rear panel to the 230V position. When operating at 230V the internal fuse located in the IEC socket should also be changed. In most 230V applications a separate power cord will be required and is not included.

The overview says "high-efficiency switching amplifier design" which had me thinking it was a class D amp, but the features section and the manufacturer's web site say it is class A/B. What do you mean by "high-efficiency switching amplifier design"?

This amp is exactly what you need. I love it and I use a Sonos to stream 4 speakers also
omar  Jun 01, 2021
The audio source amp800vs works great. I have Sonos connect hooked to it no four individual rooms in my basement
cory erik  May 31, 2021
Is the rack mount a 2U configuration?
jeffrey  Aug 09, 2019
1 answer
I cannot find any information on the height of the chassis without the rubber feet to confirm its height to check on that 2U configuration. I know the total height including the feet is 4" which is over the 2U rack specs.

what can I do to give my integrated amp more power?
wanda  Dec 01, 2016
1 answer
For assistance with that, you'll want to contact one of our Advisors directly by phone (888.955.6000) or online chat. They can go over what you have, what you want, and recommend the components & cabling you'll need to complete the installation. I hope that helps!
david  Dec 02, 2016 (Staff)
Can I connect this to the Sonos connect?
sam  Nov 29, 2016
1 answer
You can use up to four Sonos Connect players plugged into the RCA inputs on the AudioSource AMP800VS for individual playback/control in each room or zone. If you have any further questions, feel free to contact an Advisor directly by phone (1-800-324-9695) or online chat. I hope that helps!
