JBL Performance

SURR ROLLOFF

500Hz to 20.0kHz, OFF

Applies high-frequency attenuation control to the audio output connectors labeled Side L/R and Rear L/R. This filter is only applied to output signals generated by the AV1.

SURROUND DLY

0ms to 15ms

Increases the perceived depth of the listening space by delaying the arrival time of signals from the side and rear speakers. It is recom- mended that you increase the setting when a greater sense of depth is desired in the listening space.

SURROUND EX

AUTO, ON, OFF

Controls the THX Surround EX decoding feature, which can be used to extract a rear channel from 5.1-channel Dolby Digital sources.

•When set to ON, THX Surround EX decoding is engaged for all 5.1-channel Dolby Digital sources.

•When set to OFF, THX Surround EX decoding is not engaged for all 5.1-channel Dolby Digital sources.

•When set to AUTO, THX Surround EX decoding is engaged when a flagged 5.1-channel Dolby Digital source with THX Surround EX encoding is detected. THX Surround EX decod- ing is not engaged when a non-flagged 5.1-channel Dolby Digital source with or without THX Surround EX encoding is detected.

•The AV1 cannot automatically detect THX Surround EX encoding in non-flagged 5.1-channel Dolby Digital sources. A non-flagged source does not include information in the input signal that identifies THX Surround EX encoding.

The THX SurEX listening mode is available when THX Surround EX decoding is engaged. The THX and THX ULTRA2 listening modes are available when THX Surround EX decoding is not engaged. THX Surround EX decoding cannot be engaged unless both side and rear speakers are present. See “Speaker Setup” on page 3-24for more information.

When the Shift command bank is activated, pressing the remote con- trol THX button while a 5.1-channel Dolby Digital input source is present activates the THX, THX ULTRA2 or THX SurEX listening mode.

Note:

Toggling the SURROUND EX parameter setting produces low- level clicks in the front speakers.

SURROUND MIX

-5dB to +5dB

Controls the relative level of surround channel information sent to the audio output connectors labeled Front L/R. It is recommended that you set this parameter to +2dB or +3dB for all input sources.

VOCAL ENHANCE

+6.0dB, +3.0dB, +0.0dB

Controls the level of dialog boost in the audio output connector labeled Center. Increase this setting to improve dialog intelligibility, particularly at lower volume levels.
