AudioSource AMP-310 Amplifier: Clean Power Meets Ease of Use for Flexible Home Theater Applications

AudioSource AMP 310
The perfect balance of power, sound clarity and long lasting performance. View larger

AudioSource started designing and building amps over 20 years ago. Over time, AudioSource has continually refined its products to balance power, sound clarity and long-lasting performance.

Like the rest of AudioSource's line of amps, the AMP-310 is full-bandwidth capable, bridgeable, and features A-B switching, providing a repertoire of flexible configurations. It features a robust power supply and bipolar output devices, with source override to accommodate necessary interruptions such as PA systems, game consoles, phone calls, or even doorbells. All AudioSource electronics, including amplifiers, equalizers, volume controls and more, are easy to install and torture-tested during development to ensure years of use.

This AudioSource AMP-310 two-channel power amplifier is built to deliver powerful music, pure and simple, with few extra controls to get in the way. Listeners can use the AMP-310 as an independent stereo amp (150 watts x 2 into 8 ohms) when used with a preamp, as a second zone amplifier in multi-room applications, or as a rear-channel amplifier in a 6.1- and 7.1-channel system. Combine the AMP-310 with an additional monoblock amp (the AMP-310 delivers 450 watts RMS of bridged power) and a preamp, and listeners can independently drive two front left/right speakers or two rear speakers, further clarifying each channel to create dynamic high-end sound. To connect additional components to the amp, use the included stereo inputs with automatic priority override (for connecting to a source such as a receiver, CD player, or preamplifier)--or use the auxiliary output for creating a multi-amp setup.

The AMP-310 boasts a precise frequency response of 10 Hz to 50 kHz and total harmonic distortion of 0.02 percent. Additional features include A, B, or A+B speaker selector switches, a 12-volt trigger, front-panel mounted volume and balance knobs, stereo speaker level inputs, and five-way binding posts that work with both bare wire and banana plugs. Plus, at 16-1/2 by 5-1/2 by 13-3/4 inches (W x H x D), the device should fit comfortably in most rack mount or home entertainment setups. The AMP-310 works perfectly with AudioSource's AMP2UEAR rack solution. All AudioSource amps are backed by a two-year warranty on parts and labor.

Product Description

AudioSource AMP series amplifiers are designed for home and commercial audio distribution systems where high quality sound, flexibility, and reliability are essential. The AudioSource AMP 310 delivers 150 watts of stereo power and 450 watts of mono power at <0.1% THD. All AudioSource amps – AMP 102, AMP 110, AMP 210, and AMP 310 are rack-mount ready, full bandwidth capable, bridgeable for incredible mono power, and feature two zones of output with A/B or A+B speaker selection, providing a repertoire of flexible configurations. They boast a robust power supply and bipolar output devices. Front panel diagnostic LED displays show clipping to prevent over-driving your speakers. With second source override our amps automatically access secondary sources such as MP3 players, satellite radio, PA systems, paging, game consoles, phone calls or even doorbells. Speaker level inputs add another dimension to the usefulness of these fine amps; allowing for installation where only speaker wires are present to carry the signal information. For high power applications, the AMP 210 and AMP 310 are designed so users can set a safe maximum level using the rear panel master level controls, then make fine adjustments on the front panel. All AudioSource amplifiers are easy to install and are torture tested during development to ensure years of use.

The sound will get very loud if i turn it up.

So far, I have tested it once and it worked fine, in fact it sounded a little better than the Sony.
Julie
I used this to power a pair of outdoor Bose speakers on my back deck and it works well.

I've owned one of these amps now for about six months. All the complaints I've read in the reviews have come from people who obviously can't be bothered to read, pay attention, or think things through. I'm specifically referring to Auto Input Switching/Power, lack of features, and output power.

First, this is NOT an integrated amp. Nor is it designed to be used primarily as a standalone system. It is intended to be used as a node on a distributed music system. The feature set for this unit has this use in mind.

It can function as a standalone unit but if you are going to use it as such you need to use it with a pre-amp or with an input source that provides adequate line in, input selection and the tone/equalization control you want.

Second, the auto input switching. The manual isn't clear on this and the feature can't be switched off, which is why I docked it a star. But some reading and thought will provide the solution. The auto input feature is only on input 1. If you run your primary input to input 2 you will have no problem with auto switching cutting off your music during quiet passages or after the track has started. If you need to use multiple sources without the auto switch cutting the input then you need to use external input switching (see pre-amp above) and make sure the switch/pre-amp is fed to input 2 on the amp.

Auto-power on issues: This feature can be turned on or off by way of a selector switch on the rear panel of the amp. Default is on. This is in the manual.

"It doesn't have a sub out": No, but it does have a line out/pass-through for input 2 which can be used for a sub out.

"It isn't loud enough": One of two things is happening here; 1. The line in isn't sufficient to properly drive the amp. 2.

I had the reported switching problem ("UPDATE: This device has one annoying defect ... a "clever" feature of switching inputs automatically when it senses no input on one of the two stereo inputs ... any stretch of silence will cause it to switch"). I called AudioSource and I have to give them credit. The problem is relatively easy to solve by using Input 2 instead of Input 1 if you're only using one input.

Size Name: 50-Watt Verified Purchase
My stereo configuration is four KLH outdoor "rock" (they look like pieces of granite) speakers, an IPOD, and a ten-inch deep book shelf that I wanted to use as the location for the amplifier. I looked at Fry's, Best Buy, and Circuit City and couldn't find anything that was compact enough to fit on the bookshelf unless I went really high-end with a Bose setup. I had a spare Sony surround receiver that worked fine, except that it didn't fit the shelf, plus I wasn't really looking for all the bells and whistles of the receiver because I won't be using this setup to watch TV, my CD's are all on iTunes now, and I get crummy radio reception at my house. So, the technical requirements were to be able to drive the four speakers using a line-in level input coming from the IPOD. Pretty simple.

Anyhow, I purchased the Audiosource AMP100 amplifier on Amazon (to my consternation they dropped the price 3 bucks between the time I placed the order and when I received it) and it arrived in about a week using the free shipping option. It came well packed and sealed, and was as simple to set up as you'd expect of a unit like this. So far, I have tested it once and it worked fine, in fact it sounded a little better than the Sony. All four speakers were being driven normally in A+B mode. I haven't tested the auto-on feature, but it allows the box to power up automatically when it senses a signal on one of two audio inputs. The power plug on the back of the unit is unswitched (always powered). If I have any problems with the unit I'll update this post, but so far, so good.

(originally written 2005, updated 12/2013)

This is a unique device. I looked far and wide for it, and when I found it another reviewer had exactly the same need as me.

Firstly, let me help with some details. Amazon lists 3 different measurements for the depth of this device (main page, tech page, manual). The model I received is in fact:

- 8" deep using the cabinet measurement
- 9" deep including the banana plugs for speakers
- significantly deeper if one connected speaker leads with banana plugs, I use bare wire and screw in the connectors

I needed this to fit in a narrow shelf, so depth was critical. It fits perfectly, as long as I don't put banana plugs on my speakers. I threaded in the speaker wires and screwed down the banana plugs. It fit my cabinet.

The amplifier seems to have been designed to auto-switch from TV input to a CD player input. There are two rca plug inputs, one output. Two dials, balance and volume. Two sets of stereo speaker posts - A&B. You can drive A, B or both. Speakers MUST be at least 8 ohms resistance. There's even a headphone out, and you can direct sound to two speakers and the headphone.

I use low volumes and good quality (Mission) bookshelf speakers, to me the output is very agreeable.

There is one big defect that costs it two stars. Indeed, if not for the net (and other reviews here) providing a fix I'd give it one star. If you use Input 1, even if you set the switching to 'manual' and have no input 2, pauses in input sound produce a loud (to me) relay click sound. (I don't think manual every helped with this problem.)

The secret is to use Input 2, which is somehow "dominant". (See other reviews for mention of this.) Don't put anything on input 1 -- it's not worth it. If you want to switch inputs use an external device.

If this am had only ONE input and no auto-switch it would be a five star device.
