About Qualcomm aptX™ HD

aptX™ HD is a Bluetooth audio technology that reduces audio file size for efficient wireless transmission without compromising sound quality. It enables the D 3045 to deliver High Definition (HD) audio, providing a "better-than-CD" listening experience.

Bluetooth Modes

The D 3045 supports two Bluetooth modes:

• RECEIVE: Audio stream is received from a source device.
• TRANSMIT: Audio is streamed or sent to another device.

Selecting Receive or Transmit Mode: While on the BT source, press and hold the [u] button until the display shows RECEIVE. Press and hold [u] again until it shows TRANSMIT.

Bluetooth at Receive Mode

To pair a Bluetooth device:

1. On your iOS, Android, or compatible device, go to Settings > Bluetooth and scan for devices.
2. Select the D 3045's unique device ID from the list and pair/connect.
3. Upon successful pairing, the display will show "PAIRED" and then "PLAYING" when music is played.

Bluetooth at Transmit Mode

The D 3045 can connect or pair with other source devices:

1. In TRANSMIT mode, use the AMP 3 [9/0] buttons to scroll through selectable Bluetooth devices.
2. Press [4] to pair with a selected device. The display will show "Paired" and the device name. Press [u] again to unpair ("Unpaired" shown).

Note: A Bluetooth device paired in Transmit mode will not automatically reconnect when the D 3045 is powered up from standby.

Bluetooth Availability:

• BT ON (discoverable): Press and hold [BASS] button until "BT ON" is displayed.
• BT OFF (invisible): Press and hold [BASS] button until "BT OFF" is displayed.

Master Quality Authenticated (MQA)

MQA is an end-to-end technology that captures and delivers master quality audio. The D 3045 includes a decoder and renderer for MQA, ensuring MQA-encoded files sound identical to the source. It supports MQA content from Computer, Optical 1, Optical 2, and Coaxial sources.

MQA Indicators:

• MQA: Indicates decoding and playback of an MQA file, confirming provenance.
• MQA.: Indicates playback of an MQA Studio file, verified by the artist/producer or copyright owner.

Auto Standby

The D 3045 can automatically enter standby mode after 30 minutes of inactivity and no active source input.

• Enable Auto Standby: While in standby mode, press and hold the AMP 3 remote's "OFF" button until the Standby indicator blinks once.
• Disable Auto Standby: While in standby mode, press and hold the AMP 3 remote's "OFF" button until the Standby indicator blinks twice.

Auto Sense

Auto Sense allows the D 3045 to wake from standby when an active source input is detected.

Conditions for Auto Sense: Auto Standby must be enabled. If IR Learning with a TV remote is completed, Auto Sense is activated by OPTICAL 1 or OPTICAL 2 inputs. If no IR Learning is done, it activates on any source input (except analog, which wakes to Line 2). The unit powers up to the source that triggered it, unless it's an analog input.

• Enable Auto Sense Mode: While in standby mode, press and hold the AMP 3 remote's "SOURCE d" button until the Standby icon (o) blinks once.
• Disable Auto Sense Mode: While in standby mode, press and hold the AMP 3 remote's "SOURCE d" button until the Standby icon (o) blinks twice.

TV Connect

TV Connect allows the D 3045 to provide sound for your TV and learn mute/volume commands from your TV remote. It can also automatically power up to the OPTICAL source when a digital TV output signal is detected.

Configuring TV Connect:

• Connect your TV's digital optical output to OPTICAL 1 or OPTICAL 2.
• Enable Auto Standby mode.
• Enable Auto Sense mode.
• Perform IR learning with your TV remote control.

IR Learning Procedure: Point the TV remote and D 3045 front screen towards each other.

1. Press and hold [MUTE] on the AMP 3 remote to initiate IR learning mode. Display shows "LEARNING Choose One Key".
2. Press [ON] on the AMP 3 remote. Display shows "LEARNING Power".
3. Press [ON] on the TV remote. Display shows "LEARNING Press Again".
4. Press [ON] on the TV remote again. Display shows "LEARNING Power OK Next Key".
5. Repeat steps 2-4 to learn "Volume +", "Volume -", and "Mute" controls. For each, press the corresponding button on the AMP 3 remote, then the TV remote twice. The display will show learning status like "LEARNING VOL + OK Next Key".
6. Press and hold "MUTE" on the AMP 3 remote to exit learning mode. Learned functions are saved.

Note: Power ON, Vol+, Vol-, and Mute can be learned in any order.

Turn Off TV's Internal Speakers: Disable your TV's internal speakers via its setup menu for optimal D 3045 audio output.

Clear Learned IR Codes: Press and hold the D 3045's [MUTE] button. When "LEARNING... Choose One Key" appears, press and hold [MUTE] again. Learned codes are deleted when the display exits learning mode.
