Yamaha AU670 is a compact stereo hi-fi amplifier, with a USB DAC for computer connection, which is ideal for teaming with components such as the CDNT670 network streamer and CD player to create a powerful mini-system. It matches the build and sound quality of its larger contemporaries.
Playback from PC
With a single stereo line input, the AU-670 is designed to deliver high quality signal amplification for one component, delivering refined, powerful sound. The USB DAC lets you get the best quality playback from files on your computer. A great amplifier and DAC to build a powerful mini system around.
The A-U670 is a amp that thoroughly performs the essential function of an amp, which is signal amplification, and ensures refined sound quality. In order to vividly portray everything from the delicate nuance of music to energy-filled dynamism, a digital power amp that creates high power and strong drivability with strong maximum output of 65 watts/channel, is built into the component.
Natural Uncoloured Sound
Natural PWM type digital modulation with an extremely simple circuit configuration provides both natural, uncoloured sound quality as well as high efficiency. And the low-pass filter of the latter part of the power amp, which significantly influences the sound quality, is a large coil made of low-loss, low-distortion OFC wire material.
This simultaneously maintains the freshness of high-resolution sound sources, while enhancing the power of the bass and ensuring warmth in the mid and high frequency sounds—all to deliver the best quality sound reproduction, rich in musicality.
Preserve Sound Purity
To prevent corrosion, all input and output jacks are gold-plated. High sound quality parts have been installed throughout, including the large gold plated terminals compatible with banana plugs for the speaker outputs, in order to preserve the purity of sound.
This premain amp also features a special output jack that allows you to directly connect a subwoofer to the amp-providing the extra impact of a powerful bass, and filling your room with even more dynamic sound.
Simple Richly Textured
The aluminium front panel features a luxurious hairline finish, as well as an understatedly simple, elegant layout—including originally designed aluminium control knobs that reflect the top-class identity of Yamaha HiFi. This component is truly as delightful in use as it is in listening.
