Sherwood R-765 manual Speaker placement, Adjusting the speaker settings

Speaker placement

Ideal speaker placement varies depending on the size of your room and the wall coverings, etc. The typical example of speaker placement and recommendations are as follows :

Front left and right speakers and center speaker

Place the front speakers with their front surfaces as flush with TV or monitor screen as possible.

Place the center speaker between the front left and right speakers and no further from the listening position than the front speakers. Place each speaker so that sound is aimed at the location of the listener’s ears when at the main listening position.

Surround left and right speakers

Place the surround speakers approximately 1 meter (40 inches) above the ear level of a seated listener on the direct left and right of them or slightly behind.

Surround back speaker

Place the surround back speaker at the rear center facing the front at a slightly higher position (0 to 10 inches) than the surround speakers. We recommend installing the surround back speaker at a slightly downward facing angle. This effectively prevents the surround back channel signals from reflecting off the TV or screen at the front center, resulting in interference and making the sense of movement from the front to the back less sharp.

Subwoofer 60 to 90 cm

The subwoofer reproduces powerful deep bass sounds.

Place a powered subwoofer anywhere in the front as desired.

Notes :

When using a conventional TV , to avoid interference with the TV picture, use only magnetically shielded front left and right and center speakers.

To obtain the best surround effects, the speakers except the subwoofer should be full range speakers.

Adjusting the speaker settings

•After you have installed this unit and connected all the components, you should adjust the speaker settings for the optimum sound acoustics according to your environment and speaker layout.

Speaker distance settings

When enjoying multi-channel surround playback with Dolby Digital and DTS sources, it is ideal that the center and surround speakers, etc. should be the same distance from the main listening position as the front speakers. By entering the distance between the listening position and each speaker, the delay times of center and surround speakers are automatically adjusted to create an ideal listening environment virtually as if the center and surround speakers were at their ideal locations respectively as below:
