• 1, This is Kits, you need solder its by yourself.

  2, The kits default not included the two pieces hollow inductor as main pictures，if you need it, please extra pay $2.50 dollars for it. thanks!

  3, Mono protection separation degree is higher, more reliable, mutual non-interference between the two channels;

  4, 2W 10R resistor and 120nF film capacitor constitute Beiru Er network, used to cover the part of the inductance of the speaker, and to limit the high-frequency output impedance, the amplifier close to purely resistive, not easy to self-excited. Inductors for high frequency chokes, absorption peak inverse voltage speaker and inhibition of the ultra-high frequency electrical signal sent to the speakers.

  1, Boot delay (about 3S) and shutdown is power off immediately

  2, Midpoint protection ( protective output current is greater than a certain value )

  3, Input / output two kinds of wiring, joined the LED status indicator

  4, Improved power supply circuit

  5, Power Supply: Single AC 9-16V

  6, PCB Size: 65mm x 47mm

  Application: 

  One set(2pcs) board, only for OCL output circuit (dual-channel non-parallel output), delay of about 3S, each board should use a separate power supply or isolating transformer (single AC 9-16V), 3 set of interfaces：the power, signal input and signal output.
