Dsp Options - NAD T 775 Owner's Manual

DSP OPTIONS

The following signal processing parameters can be setup under the DSP
(Digital Signal Processing) Options menu.
LIP SYNC DELAY
DSP Options has the feature 'Lip Sync Delay' whose function is to match any
delay that may occur in the picture relative to the audio.
By varying 'Lip Sync Delay' from 0ms to 120ms, one can delay the audio
output in order to synchronize it with the video image.
AUDYSSEY MultEQ
Audyssey MultEQ becomes available among the DSP options only after
successfully completing Audyssey Auto Calibration (accessible through
the Setup Menu). Refer also to Audyssey Auto Calibration segment of the
Speaker Setup under Operation – Using the T 775 – Setup Menu.
Audyssey MultEQ can be set to the following levels
Audyssey: Audyssey developed target curve.
Flat: This setting is appropriate for very small or highly treated rooms
in which the listener is seated quite close to the loudspeakers. MultEQ
lters are used in the same way as the Audyssey curve, but it does not
apply a high frequency roll-o .
NAD: Ideal "in room" response developed by NAD engineers along with
Audyssey Engineers.
O : MultEQ lters are not used or no measurement process at all.

AUDYSSEY DYN EQ AUDYSSEY DYNAMIC EQ
Audyssey Dynamic EQ solves the problem of deteriorating sound quality as
volume is decreased by taking into account human perception and room
acoustics. By carefully combining information from incoming source levels
with actual output sound levels in the room, Audyssey Dynamic EQ delivers
unprecedented sound reproduction at all volume levels.
USING THE T 775 MAIN MENU
Audyssey Dynamic EQ selects the correct frequency response and surround
volume levels moment-by-moment. The resulting bass response, octave-
to-octave balance and surround impression remained the same despite
changes in volume.
Audyssey Dynamic EQ is designed to work in conjunction with Audyssey
MultEQ. Dynamic EQ determines the proper loudness compensation based
on the sound pressure level measurements MultEQ provides. Audyssey
Dynamic EQ working in tandem with Audyssey MultEQ provides the right
listening conditions for every listener at any volume level.
On: Activate Audyssey Dynamic EQ function.
O : Defeat Audyssey Dynamic EQ function.

AUDYSSEY DYNAMIC VOLUME
Audyssey Dynamic Volume delivers consistent volume playback levels,
anticipating sudden spikes and dips in volume and compensating for them
in real time. Audyssey Dynamic Volume monitors the volume of program
material moment-by-moment, maintaining the desired listening level for all
content while optimizing the dynamic range to preserve the impact.
Audyssey Dynamic Volume includes Audyssey Dynamic EQ, which
compensates for deteriorating sound quality as volume is decreased
by taking into account human perception and room acoustics. These
two technologies enable the full frequency response of the source at its
original level to be reproduced at any listening level. Even at lower listening
volumes, Dynamic Volume ensures that the richness and dynamics of the
response are maintained.
Audyssey Dynamic Volume can be set to the following levels
Light: Provide the least adjustment to the loudest or softest sound
level.
Medium: Setting that prevents loud and soft sound from being much
louder than their respective average sound levels.
Heavy: A ect volume the most by causing all sound to be of equal
loudness.
