Detection Results

“Detection Results” Screen

The “Detection Results” screen displays the Speaker Type, Distance, Trim,

Cutoff/slope and Crossover results derived from your Position 1 measurement (refer

to “Position 1 Measurement” which starts on page 8) and the recommended

Crossover derived from all of your position measurements.

• Speaker Type detects if the speaker connected to that channel is a satellite or

a subwoofer.

• Dist (feet) will automatically set the distance (delay) in the processor.

NOTE: Clicking on the heading for this column will change the display to

Dist (m) showing the distance in meters. Clicking the heading again will

change the display to show Delay (ms) showing the delay in milliseconds. A

third click will return the display to Dist (feet).

• Trim is displayed in dB. This number is not a dB SPL (absolute loudness)

number. It is an absolute trim and must be used as shown. When applied,

absolute trim gives reference level at the primary seat for volume set to

0dB. The Trim information will be automatically set in the processor.

• Cutoff/slope displays the filter characteristics applied to each speaker.

• Crossover is displayed in Hz. The Crossover information will be

automatically set in the processor. You can use the drop-down menus to

override the crossover settings that will be sent to the processor.

The Audyssey filter calculation is optimized based on your selected crossover

frequency setting in the Crossover drop-down menus. Crossover choices are listed in

descending order of preference to optimize satellite-subwoofer blending.

Only rarely should you ever choose the Large setting for the crossover. This setting

means the bass for that channel will not be sent to the subwoofer. Only in the

following situations, should you consider choosing the Large setting:

1. Your system does not have a subwoofer.
