SDP-5

MODE ADJUST

SPEECH DETECT ON, OFF

Distinguishes monaural speech from other input sources. When set to ON, effects are lowered to minimize interference and unnatural echo in monaural speech. When stereo input sources are present, the front left and right channels are independently used as inputs for ambience synthesis. When strong monaural speech is present in the input source, the monaural component of the ambience effect is reduced and the stereo component of the effect is increased. When set to OFF, the amount of ambience synthesis is dynamically controlled.

SUB LEVEL OFF, -30 to +12dB

Controls the output level of the Main Zone audio output connector labeled Subwoofer. The SUB LEVEL parameter appears on listening mode menus when the listening mode does not accommodate multi-channel output signals.

SUBWOOFER				OFF, -30 to +12dB
MODE ADJUST	(Listening Mode)	OUTPUT LEVELS	SUBWOOFER

Controls the output level of the Main Zone audio output connector labeled Subwoofer.

SURR ROLLOFF 500Hz to 20.0kHz, OFF

Applies high-frequency attenuation control to the Main Zone audio output connectors labeled Side L/R and Rear L/R. This filter is only applied to output signals generated by the SDP-5.

SURROUND DLY 0 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 recommended to 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 decoding is not engaged when a non-flagged 5.1-channel Dolby Digital source with or without THX Surround EX encoding is detected.

•The SDP-5 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 5.1 THX SurEX listening mode is available when THX Surround EX decoding is engaged. The 5.1 THX and 5.1 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. Refer to page 5-16 for more information.
