FAQ
Q: Does the volume knob control the Aux output as well?
A: No,the Aux output is simply a pass-through for the signal. Volume does
not to effect the
3.5mm Aux output.
Q: What’s the op amp chip type compatible with aiyima a07 pro?
A: A07 Pro Mini Bluetooth amplifier use 5 pcs NE5532 Dual Op Amp Chips,The
4 of the NE5532
Dual Op chips can be replacement to SRT3609SM ,OPA2604 ,OPA2134 ,LM4562
,JRC5532 , OP275GSZ ,OPA1612AIDR ect Dual Op Amp chips
Q: Why does the amplifier stop working after use a period of time?
After a period of time off, it was working again?
A: Normally, in this case, the amplifier is overheat protected, and the output
power may have exceeded the designed power,so you can lower the volume a
little and try again And check to ensure the output power of the amplifier
matches the speakers.
Q: One channel does not work?
A: 1. Check that the positive and negative poles of the speaker do not
touch each other.If they
are touch together, separate them and turn on again. Then shut down and
restart it 2. Please test whether the Bluetooth and RCA input have the same
problem first.If the two
modes have the same problem, swap the speaker cables of the left and right
channels, or change another speaker, and then test whether this channel still
does not work; 3. If only RCA or Bluetooth mode does not work, change the
audio source,change the RCA cable and test again, and make sure that all the
cables are completely pushed into the device 4. Check whether the positive and
negative poles of the audio input line or audio input line of the amplifier
are inverted.Fix and restart the amp. 5. Check whether the op amp chip inside
is loose or detached when it is turned on.There may be loose components on the
circuits, do not attempt to repair,contact us for support.
Q: All my wires are connected, but there is no sound?
A: 1 . Check whether the machine is powered onIf there is no response after
startup, you can
find a power supply with the same voltage output (must be dc24v-48v) for test.
2. If the startup is normal and there is still no sound, check whether the
input and output
lines are correctly connected. 3. If the above two points are normal, check
whether the playback device of the input sound source is suspended, muted or
the volume is at the minimum state. 4. Finally confirm the input mode, please
switched the correct input modes according to your
connect
Q: why is the sound distorted?
A: the input signal amplitude may be too large. If the volume of the
machine is adjusted to
the maximum value and the volume of the input source is also adjusted to the
maximum value, it is easy to be distorted. At this point, you only need to
lower the volume of the input source or machine.
Q: why does the volume of the machine remain the same, but the sound size
of different sound sources (such as CD first and then mobile phone) is
different?
A: the output signal amplitude is different for different playback devices.
For example, mobile phones are usually 0.35v, while CDs are 1V. The size of
natural sound is different.
Q: why does the horn make a loud current sound?
A: If you are not using the original standard power supply, please replace
the power supply
and test again. Many power sources in the market have a large disturbance
coefficient, which will cause a large current sound.
Q: why do I not connect the sound source after I plug in the input line,
and the speaker will have a great buzz?
A: when the signal line without shielding is used, there will be
interference signals entering the power amplifier for amplification. It is
recommended that you replace the signal line with shielding or unplug the
signal line.
Q: Can this machine be connected to a phonograph / record player?
A: At present, this device does not support phonograph/ record player
signal input, because
the output level of phonograph/ record player is very small, need to add a
phonograph amplifier.
Q: why does Bluetooth sound get stuck?
A: when using Bluetooth to test the distance, it is normal that the sound
does not get stuck or disconnected within 10 meters without any
obstructions.(Note: the router will interfere with the Bluetooth signal. Try
not to get close!)
