So what’s the problem? The first problem is that this is a lot more complicated than a mains transformer (a few kilos of copper and iron), a rectifier and some large capacitors. A switch mode design optimised for minimum part count will still have many tens of parts, most of which are quite delicate...

Some assorted facts The transformer in the Klimax is less than 40mm (1.5 inches) cube. At 50/60 Hz it could deliver about 5 Watts. In the Klimax it can deliver 1000 Watts. The reservoir capacitors in the Klimax are about the size of a thimble but give better filtering than ones the size of a beer ca...

The audio circuitry At Linn because we strive for continuous improvement in everything we do we use appropriate technologies to achieve our goals. There have been many fine amplifier designs over the history of audio. Some use valves (tubes), some use bipolar transistors, some MOSFETs. Some manufact...

Output current and protection A commonly asked question about a power amplifier concerns its maximum output current. There is some good reason behind this question. There is always some trade off between output power, 'specmanship', protection and cost in a power amplifier. Output power specificatio...

4. Installation The compactness of the Klimax Twin makes it very easy to install and makes possible high power multi- amplifier systems which would be impractical with conventionally designed amplifiers of similar power, because of their size and weight. The unique wall mount system can be used to m...

Mains supply The Klimax Twin has an automatic internal mains voltage switch. This allows it to operate from 90 Vac to 260 Vac. With a mains supply below 140 Vac two seconds after switching on the amplifier the power supply switches to low range, with a just audible click, and remains there as long a...

Signal sensing In the absence of a music input signal the Klimax Twin reverts to a low power standby mode after 10 minutes. The signal detector is very sensitive and waits about one second before powering up the amplifier to be certain the signal is real, not just noise. The detection threshold has ...

Inputs and outputs The Klimax Twin has both unbalanced and balanced inputs, selected by a switch on the back panel. Use the appropriate one to suit your choice of preamplifier and cabling. The LED will indicate when the unbalanced inputs are selected. Both signals are echoed out the unbalanced 'line...

5. Operation This is the easiest bit. The blue light will be dim when power is first applied, then remain dimmed with the Klimax Twin in standby mode. When a signal is detected the light brightens up as the amplifier is enabled. If the amplifier needs to protect itself it will shut down entirely for...
