5.Bluetooth 5.0 model
Suggestions:
2.0 channel mode: it is strongly recommended to make use of a max energy of DC21V and a full vary speaker of 50W*2 4Ω for the most effective working situation.
2.1 channel mode: it is strongly recommended to make use of a max energy of DC24V, a L/R speaker of 50W 4Ω and a subwoofer speaker of 100w 8Ω for the most effective working situation.
Observe:Please learn the product description and handbook rigorously earlier than utilizing the product. We will present technical assist!
Swap use:
Can select totally different sounds in keeping with particular person desire, solely impact on bass of the left and proper channel.
Pull swap inward, enhance the left and proper channel bass to full frequency output.
If the bass quantity could be very loud, it will not be apparent impact.
As a result of the bass channel output has included these bass,and the bass quantity is way louder than the quantity of the left and proper channels.
Observe: Bluetooth / AUX Audio enter
If you need Aux enter,pls disconnected the bluetooth,Press down the Whole Quantity button to decide on the working modes！
Please look rigorously,Select the appropriate speaker,Then join appropriately in keeping with your wants!
