OPERATION
USING THE M15 HD – SETUP MENU

TRIGGER SETUP

The M15 HD features three configurable +12V DC Trigger Output that
can be used to activate a component or system it is fed into. A Trigger
Input is also available to turn on the applicable link it is associated to. Use
a combination of [A/S/D/F] and [ENTER] keys to navigate through the
Trigger Setup menu parameters.
TRIGGER OUT
Triggers are low voltage signals used to turn on/off other compliant
devices. The M15 HD's three +12V DC Trigger Outputs (Trigger 1 Out,
Trigger 2 Out and Trigger 3 Out) are dependent upon the mode they
are associated with. There are six choices where +12V DC output can be
assigned and these are – Main, Zone 2, Zone 3, Zone 4, Zone 2+3+4 and
Source Setup.
Main : +12V DC is available at the assigned Trigger Out when the
M15 HD is at powered state.
Zone 2, Zone 3, Zone 4, Zone 2+3+4 : When the applicable Zone is
at powered state, +12V DC is available at the assigned Trigger Out.
Source Setup : If Trigger Output is linked to 'Source Setup, ' +12V DC
is available at Trigger Out whenever the particularly assigned Source is
selected. Please see also separate discussion about 'Trigger Out' under
the Source Setup (Normal View) section.
DELAY
The availability of +12V DC at Trigger Out can be regulated. If it is desired
that +12V DC is available without delay the moment Trigger Out is linked
to its assigned setting, set Delay to 0s. Otherwise, one can select through a
delay time of 1s to 15s.
AUTO TRIGGER IN
Auto Trigger IN allows external system controllers to toggle the associated
section of the M15 HD from "Standby" to "On" and vice versa. When the
+12V TRIGGER IN switch at the rear panel is set to AUTO, a +12V DC input at
Trigger IN will power ON the section where Trigger IN is assigned.
Main : From standby mode, the M15 HD is powered ON when +12V DC
is applied at Trigger IN.
Zone 2, Zone 3, Zone 4 : Applicable Zone is turned ON whenever +12V
DC is present at Trigger IN.
All : Main, Zone 2, Zone 3 and Zone 4 as described above will all be
activated given a +12V DC input at Trigger IN.
WARNING
If "Auto Trigger In" at Trigger Setup menu is assigned to "Main" or "All"
and the +12V TRIGGER IN switch is set to "AUTO" mode, the standby
button in the front panel as well as the corresponding ON/OFF function
keys in the HTRM remote control will be disabled effectively handling
this function to an external controller. Slide to "OFF" the +12V TRIGGER
IN switch to maintain normal power ON/OFF function procedures.

LISTENING MODE SETUP

The M15 HD has various listening mode options and is mostly configurable.
These are provided to reproduce a variety of sound effects depending upon
the content of the source to be played. Use a combination of [A/S/D/F]
and [ENTER] keys to configure the following settings.
LISTENING MODES
The audio format as detected by the selected Source can be automatically
configured and processed through the following options:
DOLBY
Dolby Digital is the multi-channel digital signal format developed in the
Dolby laboratories. Discs bearing the Dolby Digital (double-D symbol) logo
were recorded with up to 5.1 channels of digital signals, reproducing a
much better sound quality, with dynamic and spatial sound sensations that
are much better than in the previous Dolby Surround.
A Dolby Digital audio input can be configured relative to its format as
follows
Stereo: If the detected audio is of Dolby stereo format, you can default
it to one of the following settings – Pro Logic, PLIIx Movie, PLIIx Music or
None.
Surround: If the detected audio is of Dolby Surround format, you can
default it to one of the following settings –Surround EX, PLIIx Movie,
and PLIIx Music, Stereo Downmix or None.
None: If 'None' is selected, the Dolby Digital signal will be defaulted
to the 'Stereo' or 'Surround' settings set forth at the 'PCM' option. See
discussion below about 'PCM' .
