Yamaha AS700BL (Black)

180W stereo integrated amplifier

530857815

With Yamaha's Total Purity Audio Reproduction Technology at its core, the A-S700 integrated stereo amplifier fuels your listening experience with 90W-per-channel of clean, pure, high-fidelity power amplification. Look to dedicated CD Direct Amp technology to ensure the highest-quality reproduction of your favorite CD audio. Further, dual stereo speaker output pairs and an A/B selector let you power two stereo speaker pairs singly or simultaneously. Finally, multiple audio inputs - including a Phono in - ensure seamless system integration.

Total Purity? . . . It's gotta be good

There's only one reason why A/V enthusiasts choose an independent amplifier for their home audio system: superior audio performance. Which is funny, because that's the very same reason why people choose the A-S700 integrated amplifier from Yamaha. You see, without all of the extra audio- and video-processing circuitry found in A/V receivers, independent amplifiers are able to isolate audio reproduction, achieving cleaner, clearer, higher-fidelity sound from all your favorite listening sources. And the A-S700 is no exception . . . Sure, the A-S700 fuels a stereo speaker pair with an impressive 90W of power per channel, but more important than how much power this puppy puts out is how it delivers that power. Enter Yamaha's Total Purity Audio Reproduction Technology. While High Current Amplification delivers high dynamic power and low-impedance drive capabilities, advanced construction features like Input/Output Direct Symmetrical Design, Anti-Resolution Tough Base, and a solid center bar combine to minimize interference and maintain signal integrity. When you sit down to listen, you experience a broad, dynamic range of sounds that is true to your source material.

Variation on a theme

In the previous paragraph, we mentioned that an independent amplifier's principle strength is improved signal fidelity resulting from the removal of the additional A/V processing found in standard receivers. Holding true to this minimalist maxim, the A-S700 sports CD Direct amplification. In the age of compressed-audio formats like MP3 And WMA, the studio-original audio found on CD is among the highest fidelity available. When you toss the A-S700's CD Direct Amp switch, all input selectors and control circuits are bypassed, ensuring that the audio found on the CD is routed directly to the unit's power amplifier in its original form. Accordingly, you hear your favorite CD audio exactly as the artist intended.

Here, there, everywhere

So, you're thinking about setting up a stereo speaker pair in the kitchen, and another out on the back deck. The only thing that's stopping you, however, is the added cost of purchasing two separate amplifiers to power each speaker pair. How about a single amplifier that can power more than one stereo zone? How about the A-S700 from Yamaha? A quick peek at this amplifier's rear panel reveals a curious point about its design . . . two sets of speaker outputs can mean only one thing: multiple zones! Two L/R stereo speaker output pairs and a front A-B selector let you set up two stereo speaker pairs in two different rooms and use just one amplifier to power both. Imagine that you have two bookshelf speakers in the kitchen, and two outdoor speakers mounted above the deck. Set the A-B selector to A, and enjoy your tunes in the kitchen while you whip up dinner. Then, as you head out the back yard to eat at the patio table, switch the selector over to B and keep listening while you dine. Heck, there's even an A+B setting that lets you divide powered output between both speaker pairs. Maximize your audio system's performance while minimizing the number of A/V components with the A-S700 from Yamaha.

The connection

In all honesty, the headline for this little paragraph is a bit misleading . . . the A-S700 doesn't just have one connection, it sports multiple, diverse connectivity options for integrating this amplifier into your home A/V system. First, a CD audio input is linked to CD Direct Amp circuitry, ensuring optimal playback from your CD music collection. Then, a Phono input with ground terminal lets you connect your turntable directly to the amplifier, reviving all your old vinyl with clarity and fidelity. Next, four analog RCA input pairs are great for connecting to a variety of audio sources, including DVD players, portable-audio docks, and more. Finally, two analog RCA outputs allow you to output audio from one source to an audio recorder, and a REC Out Selector lets you record from one output while listening to different input.
