AIYIMA A08 PRO Bluetooth 5.0 2.0-2.1 Channel Amplifier
Front And Rear Panel Description
① VU level meter
② Bass knob
③ Treble knob
④ Power on / off / main volume control knob (red light: RCA channel / blue
light: Bluetooth channel)
⑤ Bluetooth antenna base
⑥ RCA input (automatically switch to Bluetooth channel after Bluetooth
connection, and automatically switch to RCA channel when Bluetooth is
disconnected)
⑦ 3.5 stereo output(Earphones are not suitable)
⑧ Speaker interface (red / +, black / -; L connected to left speaker, R
connected to right speaker)
⑨ Power interface (DC voltage shall not be higher than 48V)
Operation Steps
- Connect the sound source to be used to the RCA input interface of this product.
- Connect the passive speaker cable to the speaker interface of this product.
- Finally, connect the power supply (the DC voltage shall not be higher than 48V).
- Turn the on / off knob to the right to start the machine.
- Adjust the main volume and high and low volume knobs to achieve the appropriate volume and sound effect.
- If the Bluetooth and RCA are connected at the same time, Bluetooth playback take precedence. If you want RCA audio input, pls close the Bluetooth device

FQA
Q: All my wires are connected, but there is no sound?
A: 1. Check whether the machine is powered on and whether the VU level
meter light is on.
If 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, when Bluetooth and RCA are connected
at the same time, the RCA input is not working, so no audio output, pls
discount the Bluetooth connect. Thanks!
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!)
Q: Whether the volume adjust of A08 Pro can control the 3.5mm AUX output?
A:Yes,It can work.
Q: The VU meter not working?
A: When using a variable output source (Bluetooth device / phone / tablet) —
it must be set at an appropriate level because the VU meter is calibrated and
expects around a 2V line level input. Digitally controlling volume with your
device gives you Remote convenience but keep in mind that at lower levels, the
VU meter may not behave as intended. Setting your input device to full/fixed
output will restore expected VU meter behavior and volume should then be
managed manually on the A08 PRO itself.
Warning
- Please do not open the machine shell. Improper operation may cause electric shock hazard.
- Please use the switching power supply of the regular manufacturer, otherwise there will be the risk of damaging the machine.
- Please do not operate the machine in high temperature or humid environment.
