The Yamaha AU670 USB Amplifier is a compact stereo Hi-Fi player featuring a USB DAC useful for connection of the amplifier to a computer.

Connecting the AU670 to a computer via this USB DAC allows for teaming with the CDNT670 CD Player/ Streamer, or other similar components

, creating your own powerful mini-system. The Yamaha AU670 USB Amplifier is impressive in its ability to match the sound quality and overall

build of Yamaha's larger, more powerful contemporaries.

The Yamaha AU670 USB Amplifier's USB DAC has been included to allow the user to receive the best quality playback of files sent via computer.

With a single stereo line input, the AU670 delivers high standards of signal amplification for a single component, meaning your sound is refined

and as powerful as it can be. The Yamaha AU670 USB Amplifier thoroughly performs signal amplification to make sure that the sound quality is

highly refined. A digital power amp with a maximum output of 65 watts/channel which helps to create high power and drivability is included in the

component, enabling everything from the vivid portrayal of the most delicate nuance of music, all the way to rich, energy-filled dynamism.

Natural PWM type digital modulation using a simple circuit configuration within the Yamaha AU670 USB Amplifier helps to provide both uncoloured

and natural sound quality along with high efficiency. Fresh, high-resolution sound, enhanced power of the bass, and retention of warmth within the

mid and high-frequency sounds is all made possible thanks to the large, low loss, low distortion coil that is contained within the latter part of the

power amp, creating a low-pass filter. This low-pass filter is used to deliver the best quality sound reproduction that is rich in its musicality.

All output and input jacks included in the Yamaha AU670 USB Amplifier are gold plated, deterring corrosion of vital components and retaining the

quality of sound. Large, gold plated terminals are compatible with banana plugs for use with the speaker outputs, used to preserve sound purity.

Subwoofer connection is also achievable thanks to the Yamaha AU670 USB Amplifier's included output jack, allowing for direct and simple

connection to your subwoofer and filling your room with more powerful bass.
