## Description

Parameters:  The power supply voltage is used within DC ±20V to ±100V. The output of the transformer is AC voltage. The AC voltage needs to be rectified and filtered and input to the power amplifier board. Speaker protection power supply AC9V-15V (AC single voltage), transformer output direct input. Effective output power: 500W/8Ω (±95V power supply) 1000W/4Ω (±95V power supply) 1000W/2Ω (±65V power supply). It is recommended not to exceed ±65V for a 2Ω load. The output power of the power supply is basically determined by the power supply voltage and the horn impedance. The lower the voltage used, the smaller the power. Note: The matching capacitor on the board has a withstand voltage of 80V and cannot be used under overpressure. If you need to use voltage above 80V, please replace the capacitor with 100V or more. Maximum Class A power: 100W (RMS) ±45V power supply, load 8Ω, total quiescent current 2.5A Total harmonic distortion: <0.01 10W/8Ω Frequency response: 10Hz-160KHz (-3dB) Conversion rate: 25V/uS Signal to noise ratio: >95dB Gain: 40 times Power amplifier board size: 245mm × 65mm × 30mm × 2 pieces (single PCB size)  Package: PR-800 Class A /AB NJW0302 NJW0281 Dual HIFI Amplifier Board Assembled AMP 1000W（It consists of two power amplifier boards, one board one channel, with filter capacitors、power tube, and no large heat sink.）
