Note: this is a mono amplifier board,if build stereo amplifier ,you need 2 pcs   Characteristics: Operating: B class (can be adjusted to the CPI as needed)
Output Power: 300W * (8Ω) <* V = ± 55v>
Operating voltage: Recommended voltage driver stage ± 55V; current output stage ± 50V, current output stage voltage is always lower than the voltage drive level voltage of about 5V
Input interface: a mono signal input
Output Interface: mono speaker output
Power Source: Dual power supply, the voltage drive and current power output stage separate power supply, power can also be combined.
PCB Dimensions: 215 x 93.5 mm

Features:
DC servo design, so that the amplifier output is less than the midpoint of the plate within 5MV
Use the original driver Toshiba 2SA1930 / 2SC5171
Current output stage using three Toshiba 2SA1943 / 2SC5200 power transistors, low output impedance, power margin, closer to the ideal amplifier; power tubes can also be customized according to customer demand.
A perfect midpoint voltage protection circuit, speaker delay protection circuit, the main chip produced in Japan UPC1237, the integrated circuit is stable and reliable.
Voltage level / current level power designed separately, in order to avoid big fluctuations in the current level of the power dynamic when the previous stage, minimizing sound pollution.
2mm double-sided fiberglass board PCB design, 2 oz copper thickness is 2 times the normal thickness of the plate, Japan KOA Series 1% precision metal film resistors, USA mica capacitors, Germany Weimaraner capacitance, Japan Ruby and Japan Nichicon high-voltage electrolytic capacitors, all components to ensure that new imported, eliminate second-hand goods

LME49810 profile:
LME49810 mounted 300W mono amplifier board NS LME49810 latest driver IC as the core, with a variety of output stage power tube compatible use, LME49810 chip mono audio power amplifier drives a high-fidelity, ideal for audio enthusiasts and professional audio systems. Unique LME49810 chip is built Baker clamp circuit to ensure the amplifier output in the past does not occur under the driving circumstances saturation phenomenon, because the high level of the audio signal after a "soft clipping", any unwelcome audio false signal will be suppressed. "Soft Clipping" feature is very useful, because it will be easy, especially due to the strong free audio clipping and generate false signals using old solid state amplifier.

When LME49810 power amplifier board requires two mono design, consisting of the two-channel amplifier board, each channel uses a LME49810 + three pairs of power transistor (bipolar transistor and MOSFET Pin-bit compatible) design, PCB symmetrical left and right channels . PCB selection of high-quality sheet 2mm thick.

The LME49810 main parameters:

1. Wide voltage range: ± 20V to ± 100V
2. Conversion Rate: 50V / μs
3. Drive Current: 60mA (typ)
4. power supply ripple rejection ratio: (f = DC) 110dB
5. THD + noise: (f = 1kHz) 0.007
