We can do this. First check the gain settings to ensure that the gain is adjusted correctly. The fuse and connection were then checked to confirm that the fuse and connection were not broken. The signal is entered directly from the receiver to the speaker to see if the speaker is working。
If the loudspeaker basin continues to vibrate, there is a need to ensure that the power source and the ground line are robust. The speaker is in contact at both negative and negative poles, and the connection is not loose. If the problem remains, try changing the wire。
When only sound is present in the channel, it is necessary to confirm whether the receiver's balance switch is in the middle. Check if the signal lines are properly connected and switch to the left and right channel lines to check if the horn lines are intact. Enter the signal directly from the receiver to the speaker to see if there is a sound。
If the output is weak or the sound is distorted, it is necessary to check whether the input sensitivity set is correct, if the receiver balances the switch position is correct, if the signal line is strong, and if the receiver and the functional field and the horn line are fully connected. Attempts to replace the signal line by directly inputting the signal from the receiver to the speaker to confirm that the speaker phase is correct。
The high volume time job is automatically cut off to check whether the input sensitivity set is too high, whether it is well ventilated around, whether the bass control is maximum, and whether the acoustic switch is kept open. Confirm that it is reliable and uses crude power lines. If the load is 2 times, confirm whether or not it is sustainable。
If the power is not powered or visible, it is partly power failure. (b) measurement of power lines and safety tubes using a single meter to check for damage to parts of single, dual and electronic filter power components. The output voltage is normal before overhaul。
When there is no audio output, the segment is overhauled to determine whether the failure is at the front or at the working level. The front stage is enhanced by integrated circuits and the tracker probe is used to measure whether or not the output foot is signaled. Internal damage to integrated blocks will need to be replaced。
The left and right volume varies, checking the host balance button, the front input and the output left and left level control button, and the extension machine input sensitivity left and right channel settings。
When the loudspeaker is silent, the transceiver line is checked and the sound is measured using a meter。
When the volume is unstable, check the input and output rca of the power grid and the shell interface, the front and back stages, and the sensitivity knob。
