Amazon.com Product Description

The Amp 5.1 stereo power amplifier from AudioSource is a powerful and flexible addition to your home theater. You can use this monoblock amplifier by itself, or combine it with a series of Amp 5.1 units to power an entire home theater and drive speakers throughout your home.

The clean design houses a high-power amplifier that is easy to set up and easy to expand as your home theater grows. AudioSource amplifiers deliver accurate, rich sound, combining high sound-pressure levels and a clear reproduction of even the most subtle details of sound. The Amp 5.1 provides up to 100 watts per channel with total harmonic distortion of less than 0.1%.

Depending on your needs, you can place and replace several monoblock amps in one system. It’s easy to connect power sources, audio and video inputs, and speaker outputs with the expansion-friendly design. Balanced inputs allow the Amp 5.1 to connect to audio and video components with XLR outputs, and unbalanced inputs handle RCA output connections.

The front panel of the amplifier has a simple array of LED displays that signal both operating status and potential warnings. A protect warning helps you avoid overloading or overheating the unit, and it will reset the unit to the initial settings once the problem is addressed.

A phase control button allows you to switch the polarity of the speaker outputs to compensate for occasions where speakers are out of phase and sounding hollow. A low-cut control feature filters the lowest frequencies from your small speakers, preventing distortion and protecting the speakers. In the heart of the amp, the torodial power transformer generates a big sound while reducing distortion by shielding the sound from stray magnetic fields. You can control the volume directly on the unit or by adjusting the signal source component (such as your receiver, preamp, etc.).

Amazon.com Product Description

Just the thing for your burgeoning home theater or back-room listening system, AudioSource's affordable PSW100 subwoofer pounds out 100 rock-solid watts of low-end power, bringing high-impact slam to DVDs and greater ambient detail and instrumental heft to your favorite music.

A variable low-pass filter (LPF) lets you tailor the sub's output to your existing speakers. By setting the LPF high (toward 180 Hz) you can fill in the bass for bookshelf speakers that may have extremely limited bass output, while a lower setting (toward 40 Hz) will supplement and perceptually deepen the output from larger, floorstanding speakers that have more of their own low end to start with.

You're getting more than just the basics here: the PSW100 comes with a phase-reverse switch for placement flexibility (to help align the crests and dips of the different sound waves when the PSW100 and your main speakers are in different places) and auto-on signal sensing for power conservation.

You can hook up the PSW100 one of 2 ways. In the first case, you can feed the sub an RCA-tipped line-level signal from your preamplifier or surround receiver. Using this method, your receiver can most effectively route the LFE (low-frequency effects) channel from Dolby Digital, DTS, DVD-Audio, or SACD surround programs directly to your subwoofer.

Alternately, you can run speaker cable from your receiver to the PSW100 and then from the sub's outputs to your front left/right speakers. Use of this method results in a more seamless transition from the subwoofer to your speakers since the signal arriving at your speakers has already been filtered through the PSW100's internal crossover (the variable LPF discussed above). If you plan to listen to stereo music with your subwoofer, this might be the way to go.

VERY good amp for the money
very flat sounding. i'm tired of people comparing other amps and thinking they are better for one reason or another.. but thats consumer audio for you... the goal should be to have flat sound that is as true to the origional recording as possible.

at any rate, this amp doesnt stray much in frequency response across the spectrum, has practically no noise (most notably, you can turn it up all the way with no audible hiss at all) and very low harmonic distorion.

the only real downside to this amp (for this price.. or mabye even a much higher price) is that it would have a pretty hard time driving some of the bigger floorstanding speakers.. but if you have a good subwoofer, who cares, right?

AudioSource Amp One/A - great value and quality!
I bought 2 AudioSource Amp One/A's and am running them as monoblocks to drive my front L/R speakers. The difference in sound quality over my Marantz SR-5300 (brand new) is quite stunning. The sound stage sounds much wider and deeper, and even the most delicate note can be clearly heard. I'm using the Marantz as a preamp to drive the AudioSource amps, BTW. With the AS's taking the load of the front speakers, the Marantz's dynamics and clarity have also improved dramatically with multi-channel recordings since it's now only handling the center and surround speakers.

I'd recommend buying a pair of these to anyone who has a low-mid priced home theater receiver with preamp outs. The difference is quite extraordinary. I now understand why people spend thousands of $ on monoblock amps.

I also tried running the AS's stereo mode, driving Front L/R, Center and Center Surround speakers. The sound was not as dynamic or clear using them this way, though movie soundtracks sounded dramatically better (the Marantz was now doing even less). I'm more of a 2 channel music buff who happens to love multi-channel movies, so I'm sticking with the 2 monoblock approach. Eventually, I may purchase additional AS Amp ones to drive my other speakers...

OK - I guess it's obvious I'm really happy with this product. Try it for yourself, you won't be disappointed. It's the cheapest way to get a monoblock amp without spending alot more, or dealing with equipment with noisy cooling fans!

Great sound
The sound quality of this amp is much cleaner than any of the "consumer grade" stuff I own. The amp is a little short on power but an excellent piece of equipment for the price.

good value
Very happy with unit, it drives my AR302's effortlessly. Using a Marantz preamp,and Denon CD player. Clean sound, good detail. Plenty of power in mono-mode to drive my 15" subwoofer. Would buy again.

quality unit

Amazon.com Product Description

The System 230 home theater speaker system from AudioSource is designed to accurately reproduce movies and music with high fidelity and low cost. As heard through the System 230, your movies and stereo television broadcasts will sound more realistic than they would from your television speakers, putting you right in the center of the action.

You'll need a 5.1-channel audio/video surround receiver for proper surround decoding from your digital satellite receiver, Dolby/DTS 5.1-channel DVDs, or 4-channel Dolby Pro Logic-encoded TV programs. Otherwise, the System 230 gives you everything you need to immerse yourself in exciting multichannel surround sound: 4 satellite speakers (left/right front and rear), a center-channel speaker, and a powered subwoofer for driving home the kick drums, double basses, timpani, approaching dinosaurs, spacecraft, and thunderstorms from your favorite music and movies.

The included AudioSource SW380 powered subwoofer dramatically enhances the system's low-frequency performance. The SW380 features a highly efficient ported enclosure, a rugged 8-inch reinforced driver, and an 100-watt amplifier with a passive low-frequency crossover network. A choice of line- or speaker-level inputs is provided for fast and easy connection to virtually any system.

The RCA-type jacks of your SW380 are designed to accept a line-level signal from a receiver, preamp, surround processor, television, or similar device. When using a single line-level output from another component, AudioSource recommends using a "Y" connector (not included) to send the signals to both the left- and right-channel inputs. If a "Y" connector is not readily available, you can operate the subwoofer with a single RCA connection at the right-channel line-level input.

The System 230 is video shielded, allowing placement on or near your television or monitor screen without disturbing the video performance. The package includes 4 wall hangers for mounting to the wall any or all of the system's LS130 satellite speakers.

What's in the Box
Four LS130 satellite speakers (left/right front, left/right rear), 1 LS130C center-channel speaker, 1 SW380 powered subwoofer, 1 UL-approved power supply, 4 wall hangers, 16 screws, color-coded speaker wire, and a user's manual. ... Read more

Probably the best home theatre speaker kit under $100
If you've been putting off starting your home theatre system because of the high price of buying so many speakers, wait no longer. These speakers will give higher-end and certainly higher-priced competitors a serious run for their money. You can tell these are quality speakers by the cabinets' design (for example they don't have flat backs) and weight (beefy magnets). And for the price these really can't be beat.

For watching DVDs in Dolby Digital and DTS, the sound is excellent. You can drive them with receivers from 50-150 watts and they sound good at nearly all volume levels, especially in smaller rooms--great for the dynamic range (sound level-wise) of DVD movies. The 2-way center channel will make dialogue as clear as if the actors were in your living room. The satellites have plenty of range for sound effects and movie music. The sub is punchy and clear so you feel it as well as hear it, but it's not so distinct you can easily localize it (which is good). For digital music I don't think the satellites' frequency response is quite wide enough, especially at the high end. The satellites and center speaker don't have tweeters, even though they appear to have a dome when you look at them, and you have to use the sub to make up for their lack of low range (below about 180Hz). However they're certainly not bad, and in stereo mode you can hardly tell the bass isn't coming from the front channels, if you have the sub well placed and at the right level and crossover.

AudioSource's web site has the product manual available online so you can read all about the spec's and features. They come with wall mounting brackets and also have sockets for a compatible stand. They provide fairly good lengths of speaker wire but it's not high quality and you'd do well to replace it with something lower gauge. The powered sub has both LFE (RCA) and speaker-level inputs, front channel outputs, and level control. All speakers have internal crossovers.

If you're unsure of what home theatre speaker set to buy, no matter how good or bad your home theatre receiver is, you should just buy this kit. You will NOT find anything better for the price! I planned on replacing this set with something nice like the Klipsch Quintet but I haven't bothered yet because I'm getting such good sound from the AudioSource setup! Also, if you have a 6.1 or 7.1 receiver you can purchase the AudioSource satellites individually. The set also comes in two colors in case you want to match your black or silver TV/stereo. ...

The Amp 3 stereo power amplifier from AudioSource is a powerful addition to your home audio system and home theater. A simple design houses a high-end, high-power amplifier that is easy to set up and use. AudioSource amplifiers deliver accurate, rich sound, combining high sound-pressure levels and a clear reproduction of even the most subtle details of sound.

The powerful Amp 3 provides up to 150 watts per channel in stereo mode and up to 400 watts in mono. Clean, pure sound is a hallmark of the amplifier with total harmonic distortion of less than 0.04%. In the heart of the amp, the torodial power transformer generates a big sound while reducing distortion by shielding the sound from stray magnetic fields. A peak limiter circuit provides further protection against distortion in your speakers at high volumes. Discrete output devices ensure pure signal fidelity from all sources.

The Amp 3's auto-on feature powers up the amplifier whenever an input signal from an audio source is detected. The unit will shut down automatically when no signal is present. A manual power switch can also be used.

There are two pairs of speaker outputs on the Amp 3. Both outputs can be used simultaneously, as long as the combined impedance does not drop below 2 ohms. With the Amp 3, you can control the volume directly on the unit, or by adjusting the signal source component (such as your receiver, preamp, etc.) Separate channel level controls allow for individual adjustment.

Very satisfied replacement for Adcom GFA-545
When my Adcom GFA-545 died, I was shocked to see the prices for the new Adcom amps. I decided to take a chance on the AMP3 and am very satisfied with the sound and apparent quality of the AMP3. I had a simple question for tech support and was able to reach them by phone with no wait. So far, so good. I just hope it last 15 years like my Adcom. I would then give it 5 stars. ... Read more
