CALIBRATING SPEAKER DISTANCES & OUTPUT LEVELS

The SDP-40 offers manual calibration of speaker distances and output levels. Calibration helps to ensure accurate output signal arrival time and level at the primary listening position. However, it is not a substitute for proper speaker placement.

Before calibrating speaker distances and output levels:

•Set crossover points for the Main Zone audio output connectors. Otherwise, setting crossover points afterwards might invalidate calibrated output levels. (The CUSTOM or THX SETUP menu can be used to set crossover points.)

•Eliminate extraneous noises in the listening space, including conversations, air conditioners, and sounds that filter in through open doors and windows.

•Remove objects – including people – blocking the line-of-sight path between the microphones or SPL meter and the speakers.

Speaker Calibration Parameters

The table on the next page indicates the speaker calibration parameters that can be used to set speaker distances and output levels for the speakers connected to the corresponding Main Zone audio output connectors. These parameters are available on the speaker distance and output level menus shown throughout this section.

Speaker Distance Parameters

+0.0 to 30.0ft or 12.0m

Determine the distance between the primary listening position and the speaker connected to the corresponding Main Zone audio output connector.

Output Level Parameters

-18.0dB to +12.0dB

Determine the output level of signals sent to the speaker connected to the corresponding Main Zone audio output connector.

SETUP SPEAKERS MANUAL SPEAKER DISTANCES UNITS

Determines the unit of measurement in which speaker distances are calculated on ALL speaker distance menus. When FEET is selected, the SDP-40 calculates speaker distances in feet. When METERS is selected, the SDP-40 calculates speaker distances in meters. When the UNITS parameter setting is adjusted, the SDP-40 automatically adjusts speaker distances to the closest available value in the selected unit of measurement.
