Product description:
1.This is a DC-powered 12-24V power supply, using Tl's
TPA3116 high-performance digital power amplifier chip as
the core, one to do parallel bridged bass channel power
amplification output, one to do left and right channel power
amplification output.support 100W (bass channel) +50W
(left channel) + 50W (right channel) three-channel output
2 .with bluetooth version amplifier. Support Bluetooth
5.0 audio reception, external audio input interface, with
preamplifier, bass crossover processing; bass volume, bass
frequency, left and right channel volume, treble, function
control switch / total volume, 5 adjustment potentiometers
3.Wide working voltage, energy-saving design, efficiency up
to 90%. You can use a good performance switching power
supply, laptop switching power supply, you can also use a
charging bottle, or car power supply, etc...
4.The board is a finished board that has been soldered and
tested. Connect the speaker box according to the picture
connect the appropriate power supply, connect to the
Bluetooth audio device to play, or connect the sound source
input correctly.
5.The Subwoofer cut-off frequency: 26-160HZ
The main product parameters:
Size (L * W * H): 101 x 100 x 25mm, excluding potentiometer
and socket projection
Operating voltage range: DC 12-25V(current 3-4A, or
19-24V / 4-5A, such as high power requirements 20-24V /8-9A above), recommend DC24V 4A Supply power.
Note that the DC no-load voltage should not be greater thanDC24V 4A Supply power.
Note that the DC no-load voltage should not be greater than
25.5V.
Bluetooth receiving distance:> 8 m(meters)
Audio input sensitivity: 600-800mV
Frequency response range: 20Hz-20KHz
Speaker impedance
left and right channel speakers: 4-8 ohm
subwoofer speaker impedance: 2-8 ohm
Note:
The output power is related to the supply voltage/current, the
speaker impedance, and the size of the audio input. When
the power supply voltage/current is sufficient, usually the
power supply voltage is higher and the relative output pr"er
can be made larger. Speakers with different impedanc
different output powers. Usually, the speaker impedanc
smaller and the power is easier to achieve.
