AUDYSSEYDYNAMICVOLUME
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: Affect volume the most by causing all sound to be of equal
loudness.

TONE CONTROLS
The M15 HD has three Tone Control levels – Treble, Bass and Center Dialog.
Bass and Treble controls only affect the low bass and high treble leaving the
critical midrange frequencies free of coloration. The Center Dialog (‘Dialog’
in the VFD) control boosts the ‘presence’ of the midrange region improving
intelligibility of speech.
These controls allow one to tweak on-the-fly, the frequency response
of the source during playback. The control setting could be adjusted by
navigating through the Tone Controls’ OSD menu via a combination of
ENTER and
keys. The same can be managed directly by pressing the
front panel’s ‘TONE CONTROLS’ button and then rotating the Volume knob
to select desired setting.
Maximum and minimum values for all three Tone Control levels are +/- 10 dB.
‘Tone Defeat’ gives one the choice of varying or completely bypassing
the tone control section of the M15 HD. If ‘Off’ (‘Tone Active’ in the VFD) is
selected, the Tone Control circuits are active.
Select ‘On’ (‘Tone Defeat’ in the VFD) to bypass the Tone Controls effectively
defeating the effect of the tone control circuits.

PICTURE CONTROLS
Picture Controls allow video adjustments of the source material or source
components to suit one’s preference. Set the following levels or settings
according to desired level of preference.
ASPECTMODE
The Aspect Mode allows one the choice of adjusting the video output
configuration of the M15 HD.
Letterbox: Original aspect ratio is maintained, preserving the original
image’s proportions. The unused areas of the screen are left blank.
Zoom: Video display zooms in to the image or scene, cutting off
portions that do not fit. Any unused areas of the screen are left blank
(i.e., black band).
Stretch: Image or scene is stretched sideways. Any unused areas of the
screen are left blank (i.e., black band).

EDGEENHANCEMENT
Fine details of an image’s hard edges are enhanced without adding ringing
or halos. Select the level upon which the detected area will be enhanced.
Threshold: Adjusts the sensitivity of the edge detection mechanism.
A lower threshold results in more subtle boundaries of color being
identified as edges. A threshold that is too low may result in some small
parts of surface textures, film grain or noise being incorrectly identified
as being an edge.
NOISEREDUCTION
This setting addresses video distortion like video noise and blocking
artifacts.
