Receiver Setup - Digital Cinema Auto Calibration
After doing some out-of-the box casual listening to make sure the receiver, the source components, and speakers were working together, I proceeded to fine-tune the setup further using Sony's onboard Digital Cinema Auto Calibration.
Digital Cinema Auto-Calibration works by plugging in a provided microphone into the designated front panel input, placing the microphone at the main listening spot (you can screw the microphone onto a camera/camcorder tripod), going into the Digital Cinema Auto Calibration option in the speaker setup menu.
Once in the menu, you have the option to select either the Standard or Custom Auto Calibration. The Custom Auto Setup Modes changes how the equalization portion of the process is performed. The options include Full Flat (generates a flat equalization for all speakers), Engineer (Sony's reference equalization standard), Front Reference (adjusts the equalization of all speakers to the characteristics of the front speakers), or Off (no equalization performed).
After choosing which mode you want to use, there a five second countdown at which time the auto calibration process starts. As the test tones are generated, the STR-DH830 confirms what speakers are connected to the receiver, the speaker size is determined (large, small), the distance of each speaker from the listening position, and then makes equalization and speaker level adjustments.
However, keep in mind that the final results of this automatic process may not always be precisely accurate or to your taste. In these cases, you are able to go back in manually and make changes to any of the settings.
Playing a variety of Blu-ray Disc and DVD movies, in combination with several speaker setups, and in a 15x20 foot room, the STR-DH830 provided a good movie viewing experience in terms of sound staging and definition. I never felt that the receiver was straining or had problems handling dynamic content.
The STR-DH830 provides both 5.1 and 7.1 channels speaker setup options which also includes the the use of two height channels, in lieu of two back surround channels, by using the Dolby Prologic IIz option. The effect of Dolby ProLogic IIz option over a traditional 5.1 or 7.1 channel really depends on the room and whether the content lends itself to addition of front height channels. Also, if you have a small room where it is not possible to have a sixth and seventh channel behind the listening position, reinforcing the front with height speakers may add a more full surround sound experience to your setup.
There are no Blu-ray or DVD soundtracks specifically mixed for front height channels, but action movies with rain, and plane and helicopter flyover effects, as well as concert videos that include a large band or orchestra, can yield good results. Essentially, soundtracks that contain overhead or very dominate front stage elements.
As far as music reproduction goes, the STR-DH830 does well with CD, SACD, and DVD-Audio discs. However, since the STR-DH830 does not have a set of 5.1 or 7.1 channel analog audio inputs, access SACD and DVD-Audio is dependent a DVD or Blu-ray Disc player that can output those formats via HDMI, such as the OPPO players I used in this review. If you have DVD-Audio and SACD discs, make sure your DVD or Blu-ray Disc player can output these formats via HDMI.
