Audio Features
Amplifier Section: The T 785HD is rated using NAD's Full
Disclosure Power; 120 watts continuous output x 7 channels with all channels
running simultaneously from 20-20,000 Hz into 8Ω loads with no more than
0.08% THD. The stereo output is 145 watts continuous x 2 channels under the
same conditions (Using the standard FTC guidelines, typical of A/V receivers,
the power spec would be 200 watts x 7). The T 785HD utilizes twin Holmgren Toroidal
transformers to create a power supply that offers well regulated voltage,
and large quantities of current.
PowerDrive: NAD's PowerDrive technology measures each
channel's dynamic impedance individually and computes the optimum power supply
voltage required to drive the output stage for maximum power and efficiency.
Soft Clipping: NAD's Soft Clipping circuit gently limits the
output of the T 785HD to minimize audible distortion when the amplifier is
over-driven. While Soft Clipping can be left on at all times to reduce the
likelihood of audible distortion from excessive volume settings, you can also
turn the circuit off for critical listening if you prefer.
Audyssey Auto Calibration: The Audyssey auto setup and
calibration feature uses the included microphone, along with sophisticated
digital electronics to automatically setup and calibrate the T 785HD to the
exact speakers and speaker placement of your unique home theater. The receiver
automatically checks what speakers are connected (5.1 vs 7.1) and their polarity,
measures and adjusts each speaker's distance (delay time), relative level (volume),
and size (crossover point). The speakers can also be adjusted manually if you
prefer.
Audyssey MultEQ XT: Using multiple measurements from up to
eight listening positions, MultEQ XT preconditions each channel's signal to
account for the room's acoustic imperfections, resulting in a family sized sweet
spot. Because designers assume their loudspeakers will be used in typical rooms,
they are voiced to work in that bass heavy, treble absorbing environment. Once
MultEQ XT corrects for the room, this may sound too bright in the treble and too
weak in the bass region so there are three target curve adjustment options:
- Audyssey: Audyssey developed target
curve
- Flat: appropriate for very small or
highly treated rooms where the listener is seated very
close to the speakers; MultEQ filters are used in the
same way as the Audyssey curve, but it does not apply
a high frequency roll-off
- NAD: ideal in room response developed
by NAD engineers along with Audyssey Engineers
Audyssey Dynamic EQ: Audyssey Dynamic EQ solves the problem
of deteriorating sound quality as volume is decreased by accounting for human
perception and room acoustics. Audyssey Dynamic EQ works in tandem with Audyssey
MultEQ to provide well-balanced sound for every listener at any volume level.
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. The amount of compression can be set
to Light, Medium, or Heavy.
Amplifier Setup: If no surround back speakers are used in
the main zone, the surround back amplifier channels can be reassigned to Bi-Amp
the front left and right speakers (if they have bi-amp inputs) or power speakers
in Zone 2, Zone 3, or Zone 4.
MDC: NAD's answer to future technological developments is
Modular Design Construction. MDC places all the input circuitry on five easily
removable plug-in cards; your investment is protected because a single card,
rather than the entire receiver, can be replaced when a new format is introduced.
Listening Modes: The T 785HD is equipped with a Texas
Instruments Aureus 32 bit dual core floating point high speed DSP offering
various listening modes to reproduce a variety of surround sound effects,
according to the content of the source being played:

in stereo using the maximum number of speakers, useful for maximum
volume from all channels or for multi-speaker background music; the
front, center, surround, and surround back speakers can be turned
on/off as desired
- Analog Bypass: analog signals are not converted
to digital; the DSP, speaker setup, and bass management circuitry is
bypassed; bass and treble controls remain
- Stereo: all output is directed to the front left
and right speakers; low frequencies are directed to the subwoofer (if
present)
A/V Presets: A/V presets can be stored with customized
settings for listening mode, DSP options (lip sync delay), tone control,
speaker setup, and front panel display; all stored together as a single
preset.
