Pear Drop

At first there was the Flying Mole which was a compact digital amplifier boasting a tongue in cheek 100W, this little class d amplifier was well received by the Hi-Fi enthusiast and was even used in the PMC DB1s active monitor. Time and technology has moved on and B.K. Electronics now offers a digital amplifier in the same footprint as the Flying Mole but offering a true 90W RMS per channel into 4 ohms and 180W RMS bridged into 8 Ohms (Monoblock)

The Pear Drop is a state of the art class D amplifier based on a phase shift modulated topology with advanced protection circuitry that is both compact and lightweight yet it delivers clean and powerful Hi-Fi quality audio. The switch mode power supply and class D amplifier have been designed to work in synergy to produce an effortless low distortion signal.

The Pear Drop has built in over current protection which has two modes. During transients into the current limit threshold it allows constant output current but if this condition persists it goes into burst mode. This guarantees that the amplifier does not create audio holes during heavy listening but still effectively protects it during short circuiting.

The thermal protection sensor is connected to the tab of one of the output devices giving a very fast detection and shut down should over-load occur.
