NAD T175 Stereo Amplifier User Manual


 
TRIGGER SETUP
The T 175 features three congurable +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 [ ] or [ENTER] and [ ] keys to navigate through the Trigger
Setup menu parameters.
TRIGGER OUT
Triggers are low voltage signals used to turn on/o other compliant devices. The T 175’s three +12V DC
Trigger Outputs (Trigger 1 Out, Trigger 2 Out and Trigger 3 Out) are dependent on which 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 T 175 is at powered state.
Zone 2, Zone 3, Zone 4, Zone 2+3+4: When the applicable Zone is at powered state, +1 2V 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 T 175 from
“Standby” to “On” and vice versa. When the TRIGGER switch at the rear panel is set to ON, a +12V DC
input at Trigger IN will power ON the section where Trigger IN is assigned,
Main: From standby mode, the T 175 is powered ON when +12V DC is applied at Trigger IN.
Zone 2, Zone 3, Zone 4: Applicable Zone is turned ON whenever +1 2V 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 TRIGGER switch is set
to “AUTO” mode, the Power button in the front panel as well as the corresponding ON/OFF function
keys in the HTRC 1 remote control will be disabled eectively handing this function to an external
controller. Switch TRIGGER to “OFF” to maintain normal power ON/OFF function procedures.

as the “TRIGGER OUT” discussion under “SOURCE SETUP (NORMAL)”.
LISTENING MODE SETUP
The T 175 has various listening mode options and is mostly congurable. These are provided to
reproduce a variety of sound eects depending upon the content of the source to be played. Use a
combination of [ ] or [ENTER] and [ ] keys to congure the following settings.
LISTENING MODES
The audio format as detected by the selected Source can be automatically congured and processed
through the following options:
DOLBY DIGITAL
Dolby Digital is the multi-channel digital signal format developed in the Dolby laboratories. Discs
bearing the double-D symbol 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 congured relative to its format.
2 Channel: If the detected audio is a 2 Channel Dolby Digital signal, you can default it to one of
the following settings – Pro Logic, PLIIx Movie, PLIIx Music or None.
Surround: If the detected audio is a Surround Dolby Digital signal, 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 format will follow the “Digital” setting set forth at
“Other” option under this menu section. See discussion below about “Other”.
