Also, all five receivers are iPod/iPhone compatible and include Yamaha's convenient SCENE mode selection. The SCENE mode is a set of preset audio equalization options that work in conjunction with input selection.
In addition, to make receiver and speaker setup easier, all the receivers have an on-screen menu display and Yamaha's YPAO automatic speaker setup function. The RX-V675 and RX-V775WA also include analog to HDMI video conversion and both 1080p and 4K upscaling via HDMI output. For added convenience the RX-V775WA provides two HDMI outputs.
Some of the added bonus features on all receivers, except for the RX-V375, include network connectivity, which allows streaming of audio files stored on a PC and access to Internet Radio services, and both Apple Airplay and Bluetooth (via optional adapter) compatibility. The RX-V775WA also allows internet/network connectivity either by Ethernet or WiFi (built-in USB Wifi Adapter included at no extra charge).
However, the big bonus feature for 2013 is the inclusion of an MHL-compatible HDMI port on all of the receivers, except for the RX-V375. This added feature allows user to connect compatible portable devices, such as a smartphone or tablet, directly to the receiver via the MHL-enabled HDMI port (see list of compatible devices).
