Famous Swiss artisanal and audiophile audio high-end class AB mosfet power amplifier since 2016, actually at the version 3.0. Three audio same channels provide up to 392 [WRMS] total continuous power for up to a 2.1 audio system, e.g. for a home living room, a small to medium office or a recording's studio. Each channel can support up to 242 [WRMS] power on a 4 [Ω] load at 1 [kHz] without saturation. All three cinch audio inputs impedance are 50 [kΩ]; so you shall use only low capacitance high quality coaxial shielded audio/video cables. All three outputs can accept minimum 4 [Ω] loudspeakers. The frequency response goes from 1,6 [Hz] to 40,1 [kHz] at – 3 [dB]. There are only two high power mosfet transistors per channel: N and P in push-pull configuration, for a better sound's robustness, purity, power, accuracy and warmth. Inside the amplifier are 9 relays with 16 [A] gold contacts, to switch ON and OFF the device. There is a digital temperature sensor with 0,1 [°K] precision inside the heatsink; its value can be read remotely, thanks to the LAN connection which accepts a "COM over LAN" Fixmebus protocol. In case of heatsink's overtemperature, the amplifier stops above a predefined "maximum temperature", and starts again below a "minimum temperature", which are stored in the PIC18F46K22's EEPROM and are user's defined. The LAN remote control is provided by a Moxa MiiNePort E1 located on the top back side horizontal board of the amplifier. Big gold red and black loudspeaker connectors from USA, which accept large wires or banana plugs for the three channels outputs, are located on the front pannel. Your amplifier will be built for you. You have to have a little patience.
