Operation connection method:
1. Bluetooth input:
1) Power on DA650, switch the operation mode key to Bluetooth mode light BLUE;
2) Turn on Bluetooth of mobile phone and other devices, click search and connect to Bluetooth device named DA650 or YJHiFi. After connection and pairing, Bluetooth mode light BLUE is steady on.
PS: Can’t pair
• Ensure that the antenna of this product is installed and tightened.
• Ensure that the product is in pairing mode and no other devices are connected.
• Ensure that the product is within range of the pairing device (first close to the connection).
• Delete all connected Bluetooth device records from the phone or tablet device, restart the phone or tablet to restore the device’s Bluetooth driver, and reconnect the device.
3) The phone and DA650 will automatically match the best protocol, and users can also choose the protocol they want. If you want to use advanced protocols such as LDAC or aptX-HD, first confirm whether the phone supports these protocols, such as Android phone first enter the “Settings”, find the “developer options” mode, enter the drop-down to view the support of the phone:

2. coaxial input:
1) Connect the coaxial output of the player or TV to the COAX input of the DA650 via a 75 euro coaxial audio cable;
2) Set the player or TV audio to coaxial output. Audio format set to PCM;
3) Switch the signal input channel of DA650 to coaxial input mode, and the COAX light is on.
3, optical fiber input:
1) Connect the optical fiber output of the player or TV to the optical fiber (OPT) input of the DA650 via an optical fiber audio cable;
2) Set the audio of the player or TV to fiber output, and set the audio format to PCM;
3) Switch the signal input channel of the DA650 to the optical fiber input mode, and the OPT light is on.

4, Output connection:
Left and right channel (R/L) output: Connect the corresponding power amplifier or active speaker (adjust your own device to the corresponding input mode)
5, power connection:
Connect the 12V/2A power adapter (please check the power specifications, do not use non-standard power supplies) to the DA650 power DC input, and plug the adapter into the indoor power outlet.
The DC power supply has an outer diameter of 5.5mm and an inner diameter of 2.5mm. Please use 3C certified power supply to avoid the use of poorly filtered power supply to avoid current sound.

Common fault diagnosis and handling methods:
Before powering on, you should carefully check whether the connection line is normal, and you must ensure that all interfaces are correctly connected.
Common troubleshooting methods are as follows:

S/N	Fault phenomenon	Causes and solutions
1	No power	1. Check whether the power plug is fully inserted 2. Please check and briefly press the knob on the front panel to start the machine
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 the PCM format supported by the product 4. Confirm that the amplifier or speaker is turned on and connected to the unit correctly 5. Confirm the amplifier or speaker volume setting and whether it has been muted 6. Whether the sound of the signal source equipment is set as the corresponding output signal
3	Noise/abnormal sound	1. Confirm whether the input audio signal format is supported by the product 2. Check whether the wiring of analog output and power amplifier output channels is correct 3. Confirm whether the connecting wire is intact and reliably connected 4. Replace the power supply or connect the power supply and the power amplifier separately to the panel to check whether the power supply interferes

4	Bluetooth abnormality	1. Ensure that the antenna matched with this product is installed and tightened. 2. Ensure that the product is in pairing mode and no other devices are connected. 3. Ensure that the product is within the range of the matching device (close to the connection first). 4. Delete all connected Bluetooth device records from the mobile phone or tablet device, restart the mobile phone or tablet to restore the device Bluetooth drive, and then reconnect the device. 5. When the distance is too short or the connection is interrupted unsuccessfully, please check whether there is too much interference from 2.4G wireless devices around the environment (such as WiFi signal, wireless mouse, other Bluetooth devices, etc.). 6. Please do not place the equipment on metal objects, and there should be no shielding. When the signal is disturbed or blocked, it may also cause intermittent/stuck sound.
