<p>1. Use IRF240 MOS tube.</p> <p>2. The input coupling capacitor is50V \/ 3.3UFimported from Germany, and the main circuit of the electrolytic capacitor signal is .</p> <p>3. The resistor uses five-ring metal resistors, and the main circuit uses five-ring metal film resistors with an accuracy of +\/- 1% to a good signal-to-noise ratio for the whole machine.</p> <p>4. The PCB uses 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and the whole process of spraying tin to good passing performance of large and small currents. Best-in-class PCB quality. The wiring layout of the entire circuit board is quite rigorous and reasonable, and the overall PCB routing adopts a little grounding .</p> <p>5. The power amplifier board works stably and reliably with high output power; the sound is beautiful and round, and the sound field is wide. Strong three-dimensional sense, stable and solid low frequency, excellent signal-to-noise ratio, wide dynamic range; clear details, excellent transient response, all kinds of music can be handled freely, and it has a very good performance in the home playback environment.</p> <p>Power supply: + -35V to + -45V</p> <p>Power: 100W (+ -45V 4ohm)\/ 1 channel</p> <p>Distortion: is 0.012% into 1 kilohertz and full power</p> <p> is 0.015% into 10 kilohertz and full power</p> <p>Quiescent current: 20MV</p> <p>colour: as shown</p> <p>Material: ABS</p> <p>Size: 9x5.4cm</p> <p>Package Contents:</p> <p>1 Pair Amplifier Board</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
