Purchase Notice:

1.If you choose the Silver and Sky Blue option, only one amplifier will be shipped without any other accessories.
2.If you choose the Black and Grey option, you will receive an amplifier, a 24V power adapter, and a power cord. Please refer to the picture.

Product Introduction:

1.This is a powerful 2.1-channel amplifier that uses two TPA325 digital amplifier chips, with a power output of 300W * 2+600W. It can easily power a 12 inch subwoofer, with a majestic and flexible deployment.
2.To ensure high power output, a high-power output inductor is used to ensure sufficient output current. An enlarged radiator ensures stable long-term high-power operation. Built in high-power LLC switching power supply, with lower ripple and higher power, more convenient than external power supply.
3.Built in 3034 Bluetooth module, supporting APTX HD lossless transmission, coupled with independent decoding chip PCM5102, making the Bluetooth output comparable to CD player input. It is very convenient to use.
4.This amplifier can not only adjust the high and low frequencies of the left and right channels, but also adapt to different speakers. You can also independently adjust the volume and cutoff frequency of the subwoofer output, which can be well connected with the speakers of the left and right channels, making the positioning of the entire sound field more natural, and the low frequency will be cleaner and more elastic.

Instructions for use:

1. This amplifier can only be connected to passive speakers and cannot be connected to active speakers or constant voltage speakers.
2. The negative terminals of the left and right channels of the amplifier output cannot be connected together, otherwise it will cause the amplifier to burn out.
3. After the amplifier is powered on, Bluetooth will start automatically. Search for the Bluetooth name "YJHIFI" and connect to play. After connecting to Bluetooth, the RCA input will be disconnected.
