Installation and Connections
After unpacking the unit, and placing it on a solid surface capable of supporting its weight, you will need to make the connections to your audio and video equipment.
Audio Equipment Connections
There are two formats for audio connections: digital and analog. Digital audio signals are of higher quality, and are required for listening to sources encoded with digital surround modes, such as Dolby Digital and DTS. There are three types of digital audio connections: HDMI, coaxial and optical.
Since the AVR is capable of processing the audio and video portions of an HDMI signal, if your video display device has an HDMI input, you may make a single HDMI connection from your source device (such as a DVD player) to the AVR. In that case no separate digital audio connection is required.
We recommend that you use
When making connections to audio source equipment or speakers it is always a good practice to unplug the unit from the AC wall outlet. This prevents any possibility of accidentally sending audio or transient signals to the speakers that may damage them.
HDMI Connections
HDMI™ is the abbreviation for
Some source or display components in your system may use DVI (Digital Video Interface) for digital video connections. DVI carries the same digital video signals as HDMI but uses a larger connector and does not transport audio or control signals. In most cases, you may mix and match DVI and HDMI digital video connections by using optional connector adapters. Note, however,that some
HDMI Input Connections
The different “Version” levels of HDMI define which type of audio signals it is compatible with. Based on the lowest level of HDMI among your sources, the connections to the AVR should be made as follows:
•HDMI 1.0 sources carry digital video and multichannel or
that the menus in the source device are set to “Bitstream Out” or “Original” so that 5.1 digital audio is available. If you find that 5.1 Dolby Digital or DTS audio is not available on the HDMI connection, it will be necessary to make an additional connection between the source and the AVR 255/AVR 355 to either the Coaxial Ó or Optical * Digital Inputs.
•HDMI 1.1 sources carry the multichannel digital audio output from
•HDMI 1.2 (and higher) sources should be connected as shown above for HDMI 1.1, except that a separate analog connection is not needed for SACD players.
HDMI 1.3 sources should be connected as shown above for HDMI 1.1, except that a sep- arate analog connection is not needed for SACD,
In addition, the AVR will convert analog video signals to the HDMI format, upscaling to high- definition 720p or 1080p resolution. You may view the AVR’s own
HDMI cable runs are usually limited to about
3 meters. The AVR incorporates a repeater,which allows an additional 3 meters of cable between the source device and the video display.
If your video display or source device is not

HDMI Output Connections
Connect the HDMI Output # to an HDMI input on your video display. Thanks to the AVR 255/AVR 355’s video processing system, all video input signals are converted to an HDMI output, so only one connection is required between the AVR and your display.
