USING THE T 775 – SETUP MENU

trigger setup

The T 775 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 or ENTER and	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 T 775’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 775 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) 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 775 from ‘Standby’ to ‘On’ and vice versa. When the TRIGGER 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 T 775 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 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 HTR 3 remote control will be disabled effectively handing this function to an external controller. Switch TRIGGER to ‘OFF’ to maintain normal power ON/OFF function procedures.

Listening Mode Setup

The T 775 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 or ENTER and 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 Digital

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.

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.’
