SDP-40HD

Mode Adjust

5-39

Refer to the Panorama Calibration section that begins on page 5-12 for 

more information. Available in PANORAMA CALIBRATION mode.

Note:

The LISTENER POS parameter range might extend past the location of the

front left and right speakers. 

LIVENESS

30ms to 20.2s

Depends on the SIZE parameter setting. The LIVENESS parameter

adjusts the amount of effect recirculation. Higher settings mimic

more reflective surfaces and increase decay time. Available in

NIGHTCLUB and CONCERT HALL modes.

LOW FREQ WIDTH

-25 to +25

Applies low frequency spatial correction to the input signal. This

correction is applied to uncorrelated input signals below 60Hz.

Available in PANORAMA mode.

MASTER LEVEL

-5 to +5dB

Adjusts the output level of the current mode. Available in 5.1 2-

CHANNEL, DTS(-ES) 2-CHAN, 5.1mc 2-CHAN modes.

MID RT

24ms to 24.3s

Works with the BASS RT and SIZE parameters to adjust the amount

of time required for mid-frequency information to decay below

60dB in level. The full parameter range might not be available

depending on the SIZE parameter setting. Available in CHURCH and

CATHEDRAL modes.

CAUTION!

Setting the BASS RT, MID RT or SIZE parameters to a high

value may produce undesirable or damaging audio.

OUTPUT LEVELS

Opens the OUTPUT LEVELS menu, which is used to adjust output

levels for the Main Zone audio output connectors labeled Center,

Subwoofer L/R, LFE, Side L/R, and Rear L/R. Refer to page 5-33 for

more information. Available in all except 2-CHANNEL, MONO, 5.1

2-CHANNEL, 5.1 MONO, DTS(-ES) 2-CHAN, 5.1mc 2-CHAN, and

2CH BYPASS modes.

PANORAMA

ON, OFF

When set to ON, Dolby PLII MUSIC and Dolby PLIIx MUSIC listening

modes extend the front stereo image to include surround channel

signals, which creates a “wraparound” effect with side wall imaging.

Available in Dolby PLII MUSIC and Dolby PLIIx MUSIC modes.

Note:

The PANORAMA parameter within the Dolby PLII MUSIC and Dolby PLIIx

MUSIC listening modes should not be confused with the separate

PANORAMA listening mode found on page 5-12.

PRE-DELAY

1 to 100ms, OFF

Adjusts delay time between the direct sound and the onset of

reverberation. Higher settings make the simulated space sound

larger. Because some pre-delay is inherent in all source material, you

should begin with the parameter set to the lowest setting, then

make adjustments accordingly. Available in NIGHTCLUB, CONCERT

HALL, CHURCH, and CATHEDRAL modes.
