80+80W Bluetooth Digital Amplifier HiFi Power Amp Assembled CSR64215 Bluetooth 4.2 Support For APTX

Features:
1. Adopt TDA7498E digital power amplifier chip, 80W+80W high power output (4-8Ω).
2. Support AUX and wireless Bluetooth input, one key switch. Audio mode uses relay lossless switching.
3. Bluetooth adopts version 4.2 of CSR64215 solution, supports for A2DPv 1.3, AVRCPv1.6, HFPv1.6, HSP v1.2, DI v1.3, APTX, AAC.
4. MCU software control, touch buttons are more flexible and durable than mechanical control.
5. Preamp operational amplifier model is NE5532, using dual 13V voltage power supply, the dynamic sound quality is wider than single power supply.
6. The whole machine adopts all-aluminum shell, CNC finishing, matte surface treatment, laser font.


① Multi-function Button. Long press for power on and off (long press for 2s to power on, long press for 2s to power off). Short press to switch audio source input (short press for about 0.2s, cyclically switch RCA/Bluetooth.)
② Power Supply Indicator. (The indicator light is on for power-on indication. The indicator light is off for power-off indication.)
③ Input Mode Indicator. (The indicator light is on for Bluetooth input mode, and the indicator light is off for AUX line input.)
④ Volume Adjustment Knob. (Turn the knob counterclockwise to decrease the volume, turn clockwise to increase the volume.


⑤ Bluetooth Antenna Interface. Screw on the external antenna to enhance the receiving strength of the Bluetooth signal (One 2.4G external antenna. )
⑥ Bluetooth Status Indicator. (Bluetooth is searched and not connected when red and blue are flashing alternately. Bluetooth is connected when the blue light flashes slowly, and the transmitter can play audio through Bluetooth wireless transmission.)
⑦ AUX line input. Red is the right channel audio input.
⑧ AUX line input. White is the left channel audio input.
⑨ Right Channel Power Amplifier Output. Red positive and black negative, connected to passive speakers.
⑩ Left Channel Power Amplifier Output. Red positive and black negative, connected to passive speakers.
(11) DC Power Supply Input Socket. Positive inside and negative outside (5.5x2.5mm). The recommended input voltage is 32-36V, 5A.
