15. 12V Trigger IN/OUT (3.5mm jack)
    The 12V Trigger IN/OUT allows the D90 111 Discrete to be activated by other devices or to activate other devices via a 3.5mm AUX cable. The upstream device connected to Trigger In can control the power on/standby of D90 Ill Discrete, and the downstream device connected to Trigger Out can be controlled by D90 Ill Discrete.
    Before using the Trigger IN function, you need to press the button on the remote to set auto power on&standby mode to “AUTO: TRG”.

Remote control
The D90 Ill Discrete remote control offers both Bluetooth and infrared modes. When the Bluetooth remote is not paired, infrared mode is enabled. The remote indicator flashes twice when the button is pressed in infrared mode and once in Bluetooth mode.

Pairing Bluetooth remote control

1. Install two AAA batteries (not included) for the remote control.
2. Connect to the power connector with the attached power cord, and turn on the unit.
3. Press and hold the middle button and the C2 button until the red light flashes.
4. Press and hold the knob until the display shows Pairing…
5. Wait for a while, the display shows Paired which means the pairing has succeeded.

The display shows Unpaired which means the pairing has failed, please repeat the above steps.

Note:
If you need to enable infrared control, press and hold the middle button and C2 button of the remote control until the red light flashes. Then wait for the lights to go out and restart the unit.

• See “1. Auto power on & off setting” in the “Setup Menu”, below.
• See “2. Screen brightness setting” in the “Setup Menu”, below.
• Operation: press and hold the C1 /C2 button for 3 seconds to save the current settings, and “C1 IS SAVED” or “C2 IS SAVED” will be displayed after successfully saving. Short press the C1/C2 button to use the corresponding settings.
• What was saved: Volume and most settings in the setup menu, such as input channel, output channel, gain, etc (BT apTX excluded).
• When to use: This feature is suitable for users who have more than one usage scenario, such as the two shown below. Using C1&C2 buttons to save and load settings may free you from changing settings one by one when you want to change the usage scenario.

Connection

Connect to the input source
Support IIS, USB, Coaxial, Optical, Bluetooth, AES input.

Connect to an amplifier or active speakers

Setting descriptions

1. Auto power on & off set

   • Signal: The input signal will trigger the device to turn on, but if the current input is not connected or the input signal is invalid in 1 minute, it will automatically enter the standby state. Once having detected a valid signal, it will automatically return to a working state. (Default)
   • TRG: A 12V signal will trigger the device to turn on. When D90 111 Discrete’s Trigger In is connected to another device’s 12V Trigger Out, D90 Ill Discrete’s on/standby state can be controlled through this device. The D90 Ill Discrete will remain in a standby state until Trigger In detects the signal change from 0V to 12V. When changing back to 0V, the D90 Ill Discrete will return to the standby state.
   • Off: Disabled this function.

2. Screen brightness setting

   • L: Low brightness
   • M: Medium brightness (Default)
   • H: High brightness
   • A: Auto has the same brightness as Medium. The difference is that when there is no operation after 30 seconds under Auto mode, the screen will be automatically turned off and only display the current input. You can press any button to light up the screen.
