A1 operation is extremely simple, RCA signal input is analog signal input, can be connected to computer, TV, mobile phone and other audio sources, plug in the USB flash drive can easily play a variety of lossless format music, can also be directly connected to the phone Bluetooth. With audio input switch. The output is a 2-channel stereo output that can be connected to a variety of desktop passive bookshelf speakers.
 
 
Performance:
 
1. Input, RCA audio input is convenient to connect with traditional wired analog signal input; Bluetooth wireless input can be easily linked with Bluetooth devices such as mobile phones and computers.
Bluetooth uses BTM303 Bluetooth audio 5.0 module, QCC3003 chip, supports A2DP, AVRCP, HFP, AAC, I2S, etc., using 16M SPI FLASH memory chip. The Bluetooth decoding part uses the 1543 chip for decoding output.
 
2. High and low sound adjustment function, you can adjust the high and low frequency according to your needs.
 
3. Using two TPA3116D2 chips, 100W super power output per channel. It can drive all kinds of passive speakers of 4 ohms and 200Ws, 8 ohms and 150 watts or less, and fixed resistance horns.
 
4. Large heat sink.
 
 
Features:
 
1.A1 adopts a new type of horn protection circuit to ensure that the expensive speaker is not damaged. The perfect switch machine is silent design, with horn protection, overheat protection and overload protection.
 
2.A1 digital power amplifier will pass the constant temperature and humidity test before shipment (temperature: 0-45 ° C, humidity: 80%, time: 4H each)
 
3. The analog RCA signal input interface adopts heavy gold plating process to ensure the complete transmission of signals.
