DA620 Audio Conversion Splitter 4 In 3 Out DAC Manual

 

DA620 is an audio converter can freely switch four digital signals (3 optical + 1 coaxial) to one optical signal and one coaxial signal output, and at the same time convert the digital audio in LPCM format into stereo analog audio output. Can be widely used in DVD players, Blu-ray players, network players, high-definition players, PS2, PS3, Xbox360, PC and other audio conversion output.

 

Features:

• 4 channels (3 channels of optical fiber + 1 channel of coaxial) digital audio input, freely switch to one optical and one coaxial output, and convert to one 3.5 analog stereo output at the same time.
• Using 192KHz/24bit DAC audio conversion chip, it supports up to 192HZ sampling rate and is backward compatible.
• Optical output support: Dolby-AC3, DTS, THX, HDCD, LPCM digital audio format.
• Support LPCM digital audio format conversion into analog audio output.
• Audio input status indication. When there is no audio input or wrong data is input, the corresponding channel indicator starts to flash. Remote control and manual switching to select signal source output and standby mode (long press the button for 3 seconds), the operation is convenient and quick.
• High-quality sound quality, low noise. Support headphone amplifier output, can directly drive 5mm plug universal headphone.
• Power-off memory function, automatically switch to the last used signal channel after restarting.

Precautions:

Please use it correctly and maintain it properly to ensure product performance and normal operation.

Keep away from humid, high temperature, dusty, corrosive and oxidizing gas environment to avoid damage.

All parts should be free from strong vibration, and no collision, knocking, or falling to avoid damage.

Do not touch the power adapter plug of the machine with wet hands.

When unplugging the adapter plug from the power outlet, please hold the plug and do not pull on the power cord.

Please turn off the power when the machine is not in use (unplug the power adapter when not in use for a long time).

Do not open the cover of the machine, and do not touch any devices inside the machine.

The power adapter provided by the manufacturer or approved by the manufacturer must be used.

Common fault judgment and treatment: method: Before turning on the power, carefully check whether the connection line is normal, and ensure that all interfaces are correctly connected.

Common fault judgments and treatment methods are as follows:

No	Failure phenomenon	Causes and solutions
1	No power	1. Check whether the power plug is fully inserted 2. Press the button to check whether it has entered the power standby state
2	No sound	1. Whether the input signal source is turned on and connected well 2. Confirm whether the signal source channel selection corresponds to the connection line interface 3. Confirm whether the input audio signal format is PCM/LPCM format 4. Confirm that the power amplifier/TV is turned on and correctly connected to the unit 5. Confirm the volume setting of the amplifier/TV and whether it has been muted
3	LED flashing	1. The input signal is not audio in PCM/LPCM format (such as AC3, DTS, etc.) 2. The signal terminal is in no sound or mute state at this time 3. The input digital audio signal data is wrong, you need to restart the device or reconnect
