About device 5.1 hard decoding To achieve a true 5.1 surround effect, the following three points are indispensable:

1. Film source: there are downloaded movies and music files in DTS Dolby AC-3 format. 5.1 game consoles online 5.1 movie music channel.

2. Playback equipment: Sony PS2, PS3, PS4, Microsoft XBOX360 XBOX ONE with optical output, DVD and Blu-ray player with HDMI, optical, coaxial (S/PDF) output, hard disk player, computer, TV, set-top box, TV box, projector, etc.

3. Speaker or power amplifier equipment: 5.1 active speaker with 5.1 power amplifier with 5.1 analog lotus port 3.5MM input. Or it can be assembled into an independent 6-channel 5.1 power amplifier. Player source code settings: The audio source device of the player must be set to “source code” (each manufacturer has different representation methods, with source code SPD|F digital, bitstream, transparent transmission, automatic, RAW, etc.) input; decode the decoder and separate 6 channels Output through the 5.1 lotus port.

Features:

1. Support 1 PC-USB sound card input (DA615U), 1 (2) digital optical input, 1 digital coaxial input, 1 Bluetooth V5.0 input, 1 USB V2.0 interface (plug U disk to play Music), different signal sources can be cyclically switched through the INPUT button.

2. Supports 1 set of 5.1ch output, and the output ports are 3 3.5mm audio interfaces.

3. Support FLAC, APE, DTS, DTS-ES, AC3, WAV, HDCD, AAC, WMV, MP3, M4A and other digital audio format decoding.

4. Bluetooth receiver supports version 5.0, supports SBC/AAC (Apple) protocol, and supports 15-meter transmission.

5. PC-USB computer sound card supports WinXP/Win7/Win8/Win10/VISTA and other systems.

6. Automatically detect the format of the input digital audio signal. If the audio source is DTS/AC3 source code, it will be hard decoded (true 5.1 effect), if the audio source is PCM stereo, it will be soft decoded (virtual 5.1 effect).

7. It supports two output modes of switching between 2.0 and 5.1 channels by pressing the button. In 2.0 mode, it is FL/FR output.

8. Support button (long press) to adjust the volume.

9. Support USB playback of the previous song/next song and cut the song.

10. With USB playback and channel selection power-off memory function, that is, to remember the playback state before power-off.

11. Use DC 5V/1A external power adapter for power supply.

Connection operation guide:

1. Connect the 5V/1A power adapter (please check the power supply specifications, do not use non-standard power supplies at will) to the DA615 decoder power input terminal, and then insert the adapter plug into the indoor power socket. The blue indicator light will light up about ten seconds after normal startup, and then you can do key operations

2. Connect the 5.1 audio output port of the DA615 decoder to the corresponding input (INPUT) of the amplifier or 5.1 speaker through three 3.5mm to Lotus RCA cables, and switch the amplifier to the corresponding 5.1 channel input or AC-3 input ( Please refer to the text next to the interface of the machine for specific mode selection and connection). FL-left front, FR-right front, SL-left surround, SR-right surround, CE-center, SW-heavy bass,

3. Turn on DA615 and switch to Bluetooth mode (when in Bluetooth mode, the three indicators of PC-USB/oPT/COX are always off), in 5.1 output mode, the 5.1CH indicator lights up in blue, and you can search by turning on the mobile phone Bluetooth device Go to DA615, connect this Bluetooth name to pair, it shows that the connection is successful, open the mobile music player and click to play music.

4. It is strongly recommended to connect the speakers through Bluetooth mode debugging to ensure that the speakers are correctly connected to the DA615 decoder and produce sound. Then switch to other modes.

5. Key operation instructions:

INPUT button: switch the input signal source when short press, the sequence is as follows ：PC-USB->OPT->COX ->BT->USB

Long press for at least three seconds to switch the function of “51CH/2.0CH channel output”. The indicator light is on for 5.1ch, and it is off for 2.0ch.

voL+ button: Short press is the “next song” function during ∪ disc playback (short press in other modes is invalid). Long press for at least three seconds to increase the volume (long press is valid in any mode).

voL-button: Short press is the “previous song” function when playing ∪ disc (short press in other modes is invalid) long press for at least three seconds is the volume reduction function (long press in any mode is valid)

6. Description of LED indicator:

POWER: red, always on when the power is normal

PC-USB: blue, always on for “PC-USB input” mode, flashing for signal input OPT: blue, always on for “optical input” mode, flashing for signal input

COX: blue, constant light means “coaxial input” mode, flashing means signal input

5.1CH: blue, always on for “5.1 channel” output mode, often off for “2.0 channel” output mode

Note: In Bluetooth mode, the three indicators of PC-USB/oPT/COX are always off

In the USB mode, the PC-USB/OPT/CoX flashes in a circle

7. When using USB to play music, you need to format the ∪ disk into FAT32 format (16-bit recommended), and then copy the song into it

Note:

U disks were originally in MBR format. Now for the one-click installation system, some U disks are changed to GPT by default (the partition table format is GUI format). When the decoder device does not recognize the GUI format U disk, we need to convert the format For MBR format, the conversion method is as follows (as shown in the picture)

1. DiskGenius is a super hard disk partitioning tool, which can switch the U disk back to MBR format. Download to local installation:

(Please refer to the original official website instructions carefully to avoid damage to the U disk).

DiskGenius official website: https://www.diskgenius.cn/download.php

2. After the U disk is connected to the computer for identification, copy the files in the U disk to the computer’s local hard disk for backup.

3. Refer to the picture to format the U disk in MBR format, select a partition, FTA32 format.

4. After format conversion. Just copy the audio file into the U disk.

8. When using the PC-USB function, you need to install the provided USB driver, and set the USB sound card and player to achieve the true 5.1 effect by source code output

9. When using Bluetooth, because Bluetooth wireless technology can only transmit 2.0 stereo, it can only virtual 5.1 effects, and 5.1 channel separation cannot be achieved

10. The Bluetooth device name of this device is “DA615”, please install the Bluetooth antenna by yourself before use

11. The optical fiber cable needs to be unplugged before it can be inserted into the optical fiber holder. Pay attention to the direction and do not insert hard

12. When the TV or projection is connected to the decoder via optical fiber or coaxial, the TV or projection needs to be set to “external speaker” (or digital output, or “SPDIF” output), and also to source code (or RAW, or pass-through) Output.
