About the AudioSource AMP310VS
A powerful amp with flexible options
A powerful amp with flexible options
Need a ton of juice to drive your power-hungry speakers? The AudioSource AMP310VS power amp combines robust amplification with useful customization and control options. Use it as a standalone amp in a stereo music system. Or connect it to your home theater receiver's zone 2 output to drive speakers in other parts of your house.
Easily play music in two rooms
The AMP310VS 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.
The AudioSource AMP310VS power amp offers two pairs of high-quality speaker connections.
Lots of power under the hood
At its heart, the AMP310VS is an old-school power amplifier. It offers 150 watts of continuous power per channel when connected to a pair of eight-ohm speakers. It also cranks out 225 watts at four ohms.
Want to bridge the channels and use it as a mono amp for a single speaker? You'll get a whopping 450 watts of clean power from this amp.
Multiple source and power-on options
The '310VS 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 AMP310VS 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.

Pros: Gives me the power I need to run my speakers without pushing my reciver to hard
Cons: Wish it had a stand by mode so I wouldn't have to push power button

Speaker level inputs???
Michael from Covington, WA on 3/6/2019
I bought this amp to power my second set of speakers and keep my receiver from running so hot. Mission accomplished. But why only four stars? I bought this model because it has speaker level inputs and my receiver has no line level outs for another amp. The main level controls have to be set higher when using the speaker inputs. I experienced a nasty hum/buzzing when the music was paused, while still there when playing the music, it would mask it, and the unit would cut out at low volume. Crutchfield was Awesome, they sent a new one right away at no cost to me to replace it. I wanted to make sure it was not my set up causing this so I rerouted wires and bought a better surge protector etc. When the replacement arrived it performed much better but still had a humming, but not nearly as bad as the first. I was impressed with the sound quality and so did not want to send the second unit back. What solved the problem was a speaker level to line level adapter. Once I started using the RCA inputs over the speaker, absolutely no Humming/buzzing!! The master volume settings are set way lower to achieve the same volume when using the RCA inputs. Moral of the story with me,,, Don't use Speaker inputs. I love all the equipment I have from Crutchfield but plan ahead with expansion in mind if you are going to be an audiophile.
Pros: Great sound and power!!! Unit does power down when no music is being played so not having a remote to turn it on and off does not seem to be an issue. This is a HEAVY unit but not a con since it just sits there doing its job!
Cons: I do not recommend using speaker level inputs!!! Consider a new receiver with pre outs if you even think you may want to expand in the future!

Terrible stay away
John from Edwardsville, IL on 3/3/2019
Unimpressed, did not work right out of the box. Returned it for a NAD 275c BEE. The NAD is phenomenal. Do not waste your time or money in this trash.
Pros: None
Cons: Explain how a company can send out a non functioning unit. It is a reflection of the manufacturers over all quality control. Avoid!

Great Amp
Bryan from Elgin, TX on 12/30/2017
Here's another Bryan (name spelled the correct way lol) with my review of this amp. This thing has more than enough power. It's clean, clear, and easy to set up. The price for what you get is great as I got it on sale! It has A and B zones, and you can use both zones at one time. I have 2 pairs of speakers hooked up and playing both zones. WOW, my house rocks like never before. The amp has base and treble adjustments, as well as A and B zone gain adjustments on the back. Which by the way is my only complaint. I wish AudioSource would have put all the controls on the front of the amp. But I'm guessing they wanted a cleaner look. On the front are the balance and volume controls. Super easy to set up and enjoy.
Pros: Base and Treble adjustment A, B and A+B zone ability
Cons: Base and Treble controls are on the back.

Features
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 AMP310VS 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): 150 watts x 2 channel, 10-30kHz, <0.2% THD+N
- Stereo (4-ohm): 225 watts x 2 channel, 10-30kHz, <0.2% THD+N
- Bridged Mono (8-ohm): 450 watts x 1 channel, 1kHz, <0.2% THD+N
Front-Panel Controls: The AudioSource AMP310VS stereo power amplifier features the following front-panel controls.
- Power Switch: The front-panel Power Switch turns the AMP310VS 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 AMP310VS 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 AMP310VS 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 AMP310VS 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 AMP310VS digital stereo power amplifier is equipped with the following inputs & outputs
- Main Input/Output: The AMP310VS 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 AMP310VS'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 AMP310VS 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 AMP310VS 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 AMP310VS 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 AMP310VS that indicate signal clipping on the front & left channels of the amplifier.
Mounting Options: The AudioSource AMP310VS 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 AMP310VS 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.
