4.Why can't my Bluetooth device pair with the AV-735A?
①First make sure that AV-735A is turned on and currently in Bluetooth mode.
②Make sure the AV-735A is not paired with other devices.
③The distance between your device and AV-735A should not be too far. If there is some
distance, try shortening the distance between your device and AV-735A.
④Is there any obstacle between the device and AV-735A? Obstacles will affect the working
distance of Bluetooth.
⑤Please try to change other Bluetooth audio sources for testing.
⑥Please unplug the power supply, move the amplifier to another room and test it again.
⑦Restart AV-735A and try to connect it again with another brand of mobile phone.
5.Why is Bluetooth intermittent?
①Try to change the Bluetooth device.
② Is there any interference from other electronic devices between the AV-735A and the
audio source?
③Try moving the sound source closer to AV-735A.
④Restart the machine.
6.Why does a certain channel not work?
①Please first test whether the Bluetooth and RCA inputs have the same problem.
②If both modes have the same problem, please replace the cables of the left and right
speakers, or replace the former one with another speaker, and then test whether this
channel still does not work.
③If only AUX or Bluetooth mode does not work, please change the audio source, replace
the RCA cable, and test again. Make sure all cables are fully inserted into the device.
7.Why can't I start the machine?
①Please check whether the power plug is loose.
②Try pressing the power button all the way down.
8.Does the AV-735A support Bluetooth apt-X and low latency?
Not supported
GENERAL QUESTIONS:
9.Should I unplug the power cord?
If the item is not used for a long time, please unplug the power plug to prevent the AV-
735A from being burned by lightning.
10. Do I have to connect all the outputs of the AV-735A? Can I just connect one speaker? Or
just use it as a subwoofer amplifier?
You do not need to connect all the outputs. You can selectively connect the output
channels as needed.
11.Can the AV-735A be used as a 2.0 channel power amplifier? Can it be used without
connecting a subwoofer?
It can be used as a 2.0 channel amplifier and can be used without connecting a subwoofer.
12.What does the SW VOL knob do? Does it only adjust the subwoofer volume?
The SW VOL knob can only be used to adjust the volume of the passive subwoofer.
13.Which speakers are suitable for AV-735A?
The AV-735A is suitable for both passive speakers and powered subwoofers.
14.Why is the sound intermittent?
①Try to turn down the volume of the sound source.
②Try to change the audio source for testing.
③turn down the volume of treble and bass.
④Make sure the positive and negative poles of the speaker output do not touch each other.
Some larger banana plugs can easily touch each other and cause a short circuit.
15.Why is there a howling sound when using the microphone?
① Adjust the position of the microphone and the speaker, and keep a certain distance
between them, so as to avoid pointing the microphone directly at the speaker.
②Reduce the gain of the microphone and turn down the volume of the microphone to
avoid over-amplification of the sound.
③Use a microphone with low directivity to reduce the capture of unnecessary sounds.
16.Why the screen is blurry, and has bubbles and scratches on it?
There is a protective film on the screen. Remove it before use to get a better experience.
