1.Pls be sure the right wiring earlier than connecting the amplifier boar
2. Speaker wiring: Pls test our image ,it was the right join;
3. Energy on the amplifier board after conforming the wiring. Keep in mind to unplug the ability if you wish to change the wiring or transfer the board
4. Energy provide can’t be linked to the output interface of the speaker, in any other case the chip can be broken
5. Please mount set up this amplifier board on someplace with out steel and different conductive objects to keep away from inflicting quick circuit or present sound
2.0 channel mode: it is suggested 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 suggested 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
The TPA3116D2 is an Environment friendly Class D Audio Amplifier Built-in 120mΩ MOSFET that permits excessive output present as much as 7.5A permits the amplifier to supply a wonderful audio efficiency with out the necessity for a cumbersome heatsink. This machine could be configured to make use of master-slave operation of the sync pin. This helps to stop the sound of beat noise.
100W Subwoofer Amplifier Board;Frequency response vary: enter: 20 hz – 20 KHZ, output: 20 hz – 180 hz
DC 12-24V energy provide, huge working voltage, power-saving design, greater than 90% energy effectivity. Most assist 100W (Bass) bass channel output; built-in TPA3116 amplifier chip;It is a pre-amplifier, bass frequency processing, with bass quantity potentiometer management of the bass amplifier board.
Audio enter sensitivity: 500 mv;Speaker impedance: bass speaker impedance: 2-8 ohm
You should utilize a great switching energy provide adapter, laptop computer switching energy provide, or rectified filter transformer energy provide, you may also use rechargeable batteries, or car energy provide and so forth.
