OPERATION
USING THE M15 HD – MAIN MENU
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: Affect volume the most by causing all sound to be of equal
loudness.
NOTE
Audyssey Dynamic EQ must be set to "On" to activate Audyssey Dynamic
Volume. If Audyssey Dynamic EQ is set "Off", Audyssey Dynamic Volume
will also remain "Off".
IMPORTANT NOTICE
If Audyssey Auto Calibration is not set up, the relative balance of your system's
loudspeakers has to be manually adjusted (with the aid of a SPL meter) for
Audyssey Dynamic Volume and Audyssey Dynamic EQ to be effective. If the
speakers are not properly calibrated, the corresponding Audyssey Dynamic
Volume and Audyssey Dynamic EQ responses could be distorted. Refer also
to the item about "USING SPL METER" in the SPEAKER LEVELS section below.

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 [A/S/D/F] 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.

NOTE
Tone Controls options can be directly selected or changed using HTRM's
TONE button with DEVICE SELECTOR set to AMP mode. Toggle TONE
button to select "Treble", "Bass" or "Dialog" and then use the [D/F] to
adjust their respective levels. Press TONE again to save the settings and
at the same time move on to the next parameter or exit the parameter
setting altogether.

ZONE CONTROLS

Depending on the settings made at the separate 'Zone Setup' menu under
the 'Setup Menu' section discussion, the applicable Zone can be configured
and managed via this 'Zone Controls' window.
Select 'On' to activate the applicable Zone. When activated, the Source
input for the particular Zone can be allocated by selecting through the
following inputs – All enabled Sources and Local.
Select 'Local' as your selected Zone's Source input if you wish to enjoy the
same source as the main Zone and allow simultaneous listening, but with
full separate volume levels.
If a Zone is set to 'Off, ' it is deactivated or powered off.
'Volume' refers to the adjustable secondary Zone 2 Volume level that can be
increased or decreased using the D/F buttons of the HTRM.
When a Zone is activated, a corresponding Zone number is illuminated
at the VFD. Zone 2 is always available to be configured at 'Zone Controls'
menu. For Zone 3 and Zone 4 to become available at the 'Zone Controls'
window, their corresponding 'Mode' in the 'Zone Setup' menu under the
'Setup Menu' section should be set to 'Zone (Audio Only). '
NOTES
• The ZR 5 remote control will only control Zone 2 applications. Zone 3
and Zone 4 could be configured and managed at the appropriate Zone
OSD menu using the front panel navigations buttons as well as the
corresponding keys on the HTRM remote control.
• "Zone 4" is audio only and not associated with any video input sources.
