The Yamaha 675 gives you a nice array of connectivity options highlighted by it’s 6 HDMI inputs including one MHL (Mobile High Definition Link) compliant input on the front. For those of you who don’t know, MHL allows you to play HD video and multi-channel audio thru the 675 as long as you have an MHL compatible device connected such as a smartphone or camcorder. Also on the front of the 675 you’ll find a “Made for iPod” port and a USB input which supports FLAC and WAV files up to 24-bit/192kHz. The Yamaha RX V675 also has several analog audio/video connections as well as 1 component and 2 each digital optical and coaxial. The 675, like the Yamaha 673, gives you a good amount of connection options.
Let’s start by saying the Yamaha 675 does support 3D video. I’ll continue by saying this is a useless feature since . Now that I got that out of the way, another feature that the 675 support’s that isn’t irrelevant, is Ultra HD (4K). The Yamaha RX V675 supports both 4K pass through and upscaling. Ultra HD or (4K) as it was formerly known, offers roughly 4 times the resolution of 1080p. Recently, several Ultra HD TV sets have hit the market and recent price drops from and Samsung have made the new technology even more attainable. While not mainstream yet, it’s inevitable that 4K sets will overtake the market. Along with 4K support, the 675 also offers ARC (Audio Return Channel) support.
Rated at 105 watts per channel, the Yamaha RX V675 is an agile and great sounding receiver. Of the various digital sound processing modes, we felt the Sci-Fi and Standard modes sounded the best. Without using the processing modes, the sounded, just…OK. The sound didn’t quite have the gravitas that we expected. However, switching to Sci-Fi and/or Standard mode, made a world of difference. Sci-Fi mode was a little bass heavy, while Standard mode was a little more balanced. The Yamaha RX V675 like last years 673 is a top notch home theater receiver. While watching The on blu-ray, the sound moved seamlessly from speaker to speaker creating a detailed yet immersive sound field. Dialogue was also very clear and crisp and the 675 proved itself to be more than capable of producing copious amounts of bass.
