About the AudioSource AMP210VS

Kramer Crane

High-quality power for your speakers

Looking for a workhorse amplifier that doesn't take up much space? The AudioSource AMP210VS power amp's standard 2U height and included mounts make it ideal for your rack-mounted stereo system. Use it as a standalone amp, or connect it to your home theatre receiver's zone 2 output to drive speakers in other parts of your house.

Easily play music in two rooms

The AMP210VS is a great amp for setting up a two-room music system. It can drive two separate pairs of speakers connected to its A and B binding posts. Play music indoors through one set of outputs, and listen to the same source outside through the other set. When it's time to come inside for the night, simply switch off the outdoor pair and let the party continue inside.  

AudioSource AMP210VS stereo multi-source power amplifier

The AudioSource AMP210VS power amp offers two pairs of high-quality speaker connections.

Lots of power under the hood

The AMP210VS delivers 100 watts of continuous power per channel when connected to a pair of eight-ohm speakers. It also cranks out 125 watts at four ohms.

Want to bridge the channels and use it as a mono amp for a single speaker? You'll get a robust 250 watts of clean power from this amp. 

Multiple source and power-on options

The '210VS offers two pairs of analog RCA inputs for your music sources, and can switch sources automatically when a signal is detected. It can be set up to automatically turn on when it detects a source, or you can turn it on manually.

This amp is also 12-volt trigger compatible, so you can have it turn on when another piece of equipment is fired up. Rear-mounted bass and treble controls provide tone adjustment for your room.

Never worry about blowing your speakers

One of the features I like the most about the AMP210VS is the ability to set maximum volume limits. These let you set a volume "ceiling" for each channel, so even if some over-enthusiastic listener maxes out the volume knob on the front of the amp, there won't be any damage to the speakers.

This is a great way to make sure that guests or kids don't accidentally turn the system up to distortion levels.

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.

Stereo Power Amplifier: The AudioSource AMP210VS stereo power amplifier is designed for dedicated stereo & distributed audio applications. It offers A & B speaker outputs. The amplifier can be configured for Stereo or Bridged output.

  • Stereo (8-ohm): 100 watts x 2 channel, 10-30kHz, <0.2% THD+N
  • Stereo (4-ohm): 125 watts x 2 channel, 10-30kHz, <0.2% THD+N
  • Bridged Mono (8-ohm): 250 watts x 1 channel, 1kHz, <0.2% THD+N

Front-Panel Controls: The AudioSource AMP210VS stereo power amplifier features the following front-panel controls.

  • Power Switch: The front-panel Power Switch turns the AMP210VS on or off. A red LED indicates connection to AC power while in standby mode and turns green indicating audio signal is present.
  • Volume: The front-panel rotary volume knob allows you to adjust the amplifier's overall volume level.
  • A/B Speaker Selector: You can select Speakers A, Speakers B, or Both for playback.
  • Balance: The Balance control lets you fade the amplifier's speaker output between the Right & Left channels.

Rear-Panel Controls: The AudioSource AMP210VS offers the following rear-panel controls.

  • Master Level: The Master Level control sets the overall power output level and upper limit of the amplifier's left & right channel outputs, independently.
  • Bass & Treble: Bass (100Hz) & Treble (10kHz) can be adjusted from -12dB to + 12dB.
  • Stereo or Bridged Mode: Select Stereo mode for connecting one or two pair of loudspeakers. When set to Bridged mode, the AMP210VS becomes a single channel mono amplifier for powering one speaker. Only the Right audio input is used during bridged-mode. Only one zone (A or B) can be bridged; not both.
  • Delay Time: Allows for a 3 to 15 second delay to be set when switching between the amplifier's Main and Interrupting line inputs.
  • Power Mode: Set the Auto On switch to Normal for manual power on/off. Set the Auto switch to Auto for signal sensing; the amp will turn on when audio signal (>5mV) is detected at the inputs The front-panel power switch must be in the On position (pushed in) for the Auto On feature to operate. Or, select 12V Trigger which allows the AMP210VS to be powered on by other electronic component or to power on other electronics via a 3.5 minijack cable (between 3-20VDC).

Rear-Panel Connections: The AudioSource AMP210VS digital stereo power amplifier is equipped with the following inputs & outputs.

  • Main Input/Output: The AMP210VS Main Input consists of stereo RCA jacks and are used as the amplifier's primary audio inputs. The Main Output also consists of stereo RCA jacks and passthrough the AMP210VS's Main Input audio signal to another amplifier.
  • Interrupting Line Input: The Interrupting Input consists of stereo RCA Jacks. This input can be used if a second source is desired and takes over when signal is present and has at least a 5mV level. When there is no signal, or a signal with less than 5mV level, the amp switches back to Main input after a brief delay.
  • Speaker-Level Inputs: The spring-clip speaker-level inputs can be used to connect a source with speaker-level output instead of line-level outputs. Route this high-level input signal to either the amplifier's Line 1 or Line 2 input.
  • Speaker A/B Terminals: The AudioSource AMP210VS is fitted with binding-post terminals for A & B speaker connection for powering up to two pair of speakers. The minimum impedance for each speaker section is 4-ohm in Stereo mode and 8-ohm in Bridged mode. The binding post terminals will accept bare wire (up to 10AWG), pin-connectors, and banana plugs (single or dual).
  • Trigger In/Out: The 12V trigger input and output allow the AMP210VS to be powered on by other electronics or to power on other electronics via a 3.5mm minijack cable.
  • Power Cord: The stereo power amplifier features a detachable 6' AC power cord (IEC 3-prong).

Front-Panel LEDs: The AudioSource AMP210VS features front-panel LEDs to indicate Power/Standby, Audio Signal, and Clipping.

  • Power/Standby Indicators: Red LEDs behind the faceplate indicate power status. Whenever the amplifier's power switch is in the "On" position the ring around the button is illuminated. During "Standby" status (no signal) the side lenses are not illuminated and the signal LEDs show orange.
  • Audio Signal Indicators: When the amp is "Active" (receiving signal) the side lenses become illuminated and the signal LEDs show green.
  • Clipping Indicator: There are two LEDs on the front-panel of the AMP210VS that indicate signal clipping on the left and right channels of the amplifier.

Mounting Options: The AudioSource AMP210VS stereo power amplifier features four rubber feet and can simply be placed on top of a flat surface; like a table-top, shelf, or stand. It can also be rack-mounted (rack-ears included).

Applications: The AudioSource AMP210VS can be used a remote amplifier, single or dual zone amplifier, rear channel amplifier for a home theater setup, or a stand-alone stereo amplifier.

Customer Q&A

7 questions already asked

I read in one review that they connected their Denon 800 H 2 channel receiver to this amp using banana plugs at the receiver and RCA plugs at the amp? how is this possible? My Denon 800 H has zone 2 pre out but no main pre out. I would assume it would be better to connect to the zone 2 pre out and use the bass and treble controls on the amp (if needed) Oh 1 more thing, if I were to use this amp and connect to zone 2 pre out would the sub pre out on my receiver still work?

For the best possible sound quality, we advise using RCA preamp outputs for signal, Robert. You can connect the AudioSource AMP210VS to your zone 2 preamp outs, and your subwoofer specific preamp output will still send a signal, no problem there. If you desire to adjust the bass/treble, you can on the rear panel of the AudioSource AMP210VS. I have been personally using AudioSource amps for years, and the clean 210VS AB amplifier is an astounding value for its performance!

Wattage per channel on 6 ohm speakers?
clinton  Jul 12, 2022
1 answer
This AudioSource AMP210VS (one of my personal favorites) is rated for 125 watts at 4 ohms. This would most likely put out somewhere around 112 watts or so to a 6 ohm speaker. These AMP210VS's have been consistently one of the top power options for the money, an excellent piece!

I bought a Marantz SR7015 and currently have a 7.1.2 Dolby Atmos Surround System. I want to add 2 more Atmos speakers for a 7.1.4 system, but I need an external pre-amp since I have used all my speaker outputs on my Marantz SR7015. Since my existing and future Dolby Atmos speakers are Polk SR90s that have a max power rating of 100 watts, the size of this pre-amp seems perfect. I am asking for your opinion as to if this pre-amp is a good choice for my application because in another site's customer reviews, someone said only use with stereo since using it with Dolby Surround would have issues. I thought this person's reviews was a bit confusing to understand, but since I saw their comments, I wanted to confirm that you felt using this as a pre-amp for Dolby Atmos height speakers would be acceptable?
ryan  Mar 10, 2022

Well, I think your sources and the Receiver needs to support Dolby Atmos and I have your problem, 7.1.4 Pioneer Receiver SC-LX801 and ran out of outputs. It's a 9 ch amp, but because I bi-amp my front large Paradigm Studio speakers, put me in a situation. I'm pre outing my Height 2 jacks to this AudioSource amp for my Atmos speakers. My Receiver allows me to direct the outputs for different configurations. The Pioneer manual directed me on what to do, hope this helps?
ronald eric  Mar 13, 2022
I would think it would work great for that! I like mine, works well.
kenneth  Mar 12, 2022
Will this work if I use the amp to power the main speakers and run the amp's output to a powered subwoofer?
darin  Oct 09, 2021
1 answer
If you are asking about the Main preamp outputs, those can be ran to a powered subwoofer that has a low pass filter built into it. In order for this to work, the Main preamp inputs must be getting full range audio (bass included).

I recently purchased a AMP 210VS and music is cutting out randomly . Any suggestions to remedy this problem?
joseph  Dec 25, 2020
3 answers
It could be that you have the amp set to "Auto On" or Trigger", and your incoming signal is low. Set your amp to "Normal" and it should stop the music from randomly cutting out.
marcus  Dec 30, 2020
No idea, not a technical person. Hope it's still under warranty.
robin  Dec 30, 2020
This may sound basic but check wiring. I had mine run to outdoor speakers (one of which was bad but didn't know it) and it caused the Amp to go into protection mode. If that is what is happening, check connections, speakers, and your receiver to make sure they are all working correctly. If they are, then it could be the AMP.
scott and kim  Dec 29, 2020
Can I run three pairs of speakers on this in parallel?
kenny  Feb 01, 2020
2 answers
I really can't tell you what you ask can or should be done it might be done with a multi pair speaker selecter(at least 3 pair ) one that is wired in parallel and one that. keeps the impedance at the correct level the information on any speaker selecter you might purchase would say whether it will do these things I think this might work my answer is not "god breathed if I wanted to do this thing this is what I would try I dont set up other people's system because I am not licensed I have made mistakes with my equipment but nothing unforgivable but I do give advice I am late with this answer the internet was down here I hope this helps THANK YOU
galen  Feb 04, 2020
No, it has only 2 channels, A and B, which run 2 speakers each. If it's possible to run more than 2 speakers through each channel, I don't know how that would be done.
