Audio Amplifiers
$89.99 $52.99
1.With two audio inputs, one AUX input is convenient to connect to traditional wired analog signal inputs; there is also one Bluetooth wireless input, which can be easily connected to Bluetooth devices such as mobile phones and computers, without being bound by wires, and easily enjoy music.
2.Adopt treble, midrange, and low tone design: increase the treble, midrange, and low tone so that all frequency bands of the audio source are within an adjustable range.Users can enhance or attenuate the midrange, treble, and low frequencies according to their personal preferences until they achieve the best sense of experience.(Most of the treble and bass frequencies on the market).
3.Increase the output of the active device that can be connected, so that the active subwoofer or the next active power amplifier device can be added (which can bring you the continuity of 2.1/4.1 channels).
4.Two TI TPA3116 power amplifier chips are used, and one TPA3116 is used for PBTL mode for each channel: the distortion is lower, it can support greater output power, and the speaker output can support the lowest energy to 2 ohm impedance (most of the market is a TPA3116). 3 NE5532 op amps are used internally.
5.The Bluetooth part adopts imported Qualcomm QCC3034 high-quality Bluetooth 5.1 receiving chip, which brings you low latency, APT-X HD lossless high-definition sound quality.
6.The output power inductor uses shielded inductors to better protect the wires, loops, and coils from the influence of external magnetic fields, as well as to weaken the interference of the electromagnetic fields generated by the circuit to other components.
7.Supply voltage: DC15V-24V, 3A or more. Voltage socket 5.5*2.5mm, negative outside and positive inside.The DC seat uses all-metal materials with fireproof flowers, which is safer to power on and provides a guarantee for stable work with high power.
8.No switch on and off machine impact sound, protect your speaker
9.Large heat sink, long-term high-power stable work to provide a guarantee
10.The knob functions are from right to left: total volume adjustment, left and right channel treble adjustment, left and right channel mid-tone adjustment, left and right channel bass adjustment
