connectionversusoperating:
1. Connect the audio signal source via optical fiber or coaxial cable (DVD/PS3/XBOX360/HD player, etc.)
2. Connect * with the power amplifier through the analog audio cable;
3. Connect the speakers through the speaker cable;
4 Connect the power adapter to the mains, and turn on the power amplifier and signal source.
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, no collision, knocking, falling, so as 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 components inside the machine.
- Must use the power adapter provided by the manufacturer or approved by the manufacturer
Before powering on, you should carefully check whether the connection line is normal, and you must ensure that all interfaces are properly connected. Common fault judgments and treatment methods are as follows:
Serial number | Failure phenomenon | Causes and solutions |
1 | No power | 1.Check whether the power plug is correctly inserted into the power socket. 2.Check whether the power is turned on. |
2 | No audio output | 1. Make sure that the audio signal source is connected to *. 2. Make sure * is in the input channel. 3.Check whether the analog output is connected to the 5.1 input interface of the power amplifier. 4. Check whether the power amplifier is in 5.1 input state, whether it is turned on at the same time, and whether the volume adjustment is normal. 5. Is the audio cable intact? |
3 | Murmur | 1. Reconnect the connection port to prevent poor contact of the socket interface 2. Wire quality（The wire terminal is rusty, open, etc.） 3. Is there any noise in the source of the audio? |
