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. 

AudioSource AMP310VS stereo multi-source power amplifier

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.

Wow !! What a great product. I mated this amplifier to my Yamaha rs700 and really woke up my tower speakers. The sound is clean and powerful with no distortion . I ordered this product on Friday and received it on Monday morning. Thanks Crutchfield for your fast service and great price.

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.

I'm afraid not. AudioSource lists the minimum bridged impedance at 8-ohm for this AMP310VS model. There may be another amplifier better suited for your 4-ohm speaker(s) though--please feel free to contact an Advisor by phone (888.955.6000) or online chat to discuss other amplifier options in more detail.
