JBL SDP-40HD manual Listening Mode Menu Option & Parameter Descriptions

SDP-40HD Mode Adjust

LISTENING MODE MENU OPTION & PARAMETER DESCRIPTIONS

5 SPKR ENHANCE ON, OFF

Simulates 7-channel playback in 5-channel speaker configurations. When set to ON, the SDP-40HD provides an increased sense of spaciousness and envelopment through the surround speakers. This enhancement is most noticeable when the surround speakers are positioned to the sides of the primary listening position, or when the primary listening position is located against the rear wall. The effec- tiveness of this parameter varies within the listening space. For best results, place the surround speakers to the left and right of the primary listening position. Available in all Logic 7 modes.

ACADEMY FILTER ON, OFF

Restores the proper tonal balance of older mono film sources that have much narrower frequency responses than more recent mono film sources. Available in MONO LOGIC and 5.1 MONO LOGIC modes.

AUTO AZIMUTH ON, OFF

Maximizes matrix steering accuracy. When set to ON, the SDP-40HD continually monitors the 2-channel input signal and automatically adjusts the relative level and time offset of the input channels to ensure that signals are sent to the appropriate channels with maximum separation. When set to OFF, the accuracy of the selected listening mode varies among sources. Set this parameter to ON for film and broadcast sources and to OFF for music sources. Available in L7 FILM and L7 TV modes.

BASS CONTENT BINAURAL, MONO, STEREO

Adjusts the bass content of binaural, mono and stereo recordings. When set to BINAURAL, low frequency compensation is activated. Select this setting for true binaural sources recorded with dummy head microphones. Select the MONO setting for sources recorded

with mono bass. Select the STEREO setting for sources recorded with stereo bass. Available in PANORAMA mode.

BASS ENHANCE ON, OFF

Enhances stereo bass, which results in low frequency reproduction that is less localized and more realistic in the listening space. The effectiveness of the BASS ENHANCE parameter varies depending on room acoustics and the ability of the surround speakers to reproduce low frequencies. For best results, use front, side or rear speakers that are capable of reproducing frequencies of 40Hz or lower. Available in all Logic 7 modes.

BASS RT 5ms to 48.6s

Works with the MID RT and SIZE parameters to adjust the amount of time required for low frequency information to decay below 60dB in level. In smaller listening spaces, the BASS RT parameter setting should match the MID RT parameter setting for more natural effects. Available in CHURCH and CATHEDRAL modes.

CAUTION!

Setting the BASS RT, MID RT and SIZE parameters to a high value may produce undesirable or damaging audio.

CALIBRATION

Opens the PANORAMA listening mode CALIBRATION menu, which is used to calibrate the PANORAMA listening mode. Refer to “PANORAMA” on page 5-12 for more information. Available in PANORAMA mode.
