SOUND STAGE (FRONT, NEUTRAL, REAR)

SOUND STAGE dynamically adjusts the relative balance of the outputs when no surround signals are present. When set to FRONT, the SIDE L/R and REAR L/R outputs are attenuated, shifting the per- ceived balance of the sound field to the front of the listening space. When set to NEUTRAL, the SIDE L/R and REAR L/R outputs are attenuated slightly, shifting the perceived balance of the sound field to the center of the listening space. When set to REAR, the SIDE L/R and REAR L/R outputs are not attenuated, preserving the intended balance of the sound field.

SUB L/R and SUB L/R LVL (OFF, -30 to +12dB)

SUB L/R (Subwoofer Left/Right) and SUB L/R LVL (Subwoofer Left/Right Level) adjust the output level of the SUBWOOFER L/R outputs.

SURR ROLLOFF (500Hz to 20.0kHz, OFF)

SURR ROLLOFF (Surround Rolloff) simulates the high frequency rolloff that occurs in real spaces. When set within its 500Hz to 20kHz range, the unit applies a high-frequency rolloff to the SIDE L/R and REAR L/R outputs. When set to OFF, the unit does not apply this high-frequency rolloff.

SURROUND DLY (0 to 15ms)

SURROUND DLY (Surround Delay) increases the perceived depth of the listening space by delaying the arrival time of the SIDE L/R and REAR L/R outputs. This time delay can be set within a range of 0 to 15ms. Increasing this time is recommended when a greater sense of depth is desired in the listening space.

SURROUND EX (ON, OFF)

SURROUND EX activates and deactivates the 5.1 THX SURROUND EX listening mode, provided both side and rear speakers are select- ed (see page 3-18). The default value of the SURROUND EX parameter is ON, which activates 5.1 THX SURROUND EX. When set to OFF, the 5.1 THX SURROUND EX listening mode becomes

5.1THX. (See page 5-10 for more information.) Toggling the setting of the SURROUND EX parameter produces low-level clicks in the front speakers.

SURROUND MIX (-5 to +5dB)

SURROUND MIX adjusts the relative level of the surround channels that are encoded into the FRONT L/R outputs. The recommended setting is +2 to +3dB for all input types.

VOCAL ENHANCE (+0.0dB, +3.0dB, +6.0dB)

VOCAL ENHANCE adjusts the level of dialog boost in the CENTER output. Increasing this level is recommended for listening at lower volume levels or for increasing dialog intelligibility.
