Lyngdorf SDA2175

Hej! Här säljer jag ett jättefint och kraftigt slutsteg i near-mint tillstånd. Notera att det rör sig om en rejäl torustrafo slutsteg trots att det är semidigitalt vilket bidrar till ljudet signifikant.

Lyngdorf SDA 2175 is a compact, high performance semi digital switch-mode amplifier utilizing some of the circuit topologies originally developed for the Lyngdorf Millennium amplifier. Due to the switch-mode topology, with an efficiency of up to 85%, the SDA 2175 will provide its output power with minimal heat dissipation. A massive power supply with a 650VA toroidal transformer and more than 40000 microF capacitors ensures that the SDA 2175 can deliver the current to drive even the most demanding loudspeakers. The SDA 2175 has 2 gold-plated XLR connectors accepting balanced input signals and 2 gold-plated phono connectors for unbalanced signals. The input signal is fed to the power amplifier circuit via an AC-coupled true instrumentation type input amplifier. Except for the input amplifier, the SDA 2175 is fully DC coupled with no bypass capacitors or DC servos to degrade performance. The protection circuitry in the SDA 2175 shuts down the unit in case of over-temperature, DC voltage on the outputs and too high output current. The amplifier will resume normal operation when the fault condition is no longer present. A trigger input and bypass on 3.5 mm minijack connectors allow the SDA 2175´s standby mode to be controlled remotely.
