The result of years of experience, the Klimax uses the latest technology and exemplifies o u r c o n s t a n t e n d e a vo u r t o m a k e e ve r b e t t e r s o u n d i n g p r o d u c t s.

4 3. How does the Klimax work? In most power amplifiers the power supply comprises a large transformer, a rectifier and reser voir capacitors, often as large as the transformer. The highest performance amplifiers also have voltage regulators which maintain the power supplied to the amplifier circuit...

5 In a switch mode power supply the incoming mains is filtered then rectified to generate a very high voltage dc (direct current) supply. This is usually about 300 to 350 Volts dc, which is far too high to operate audio circuitry directly, and is still connected directly to the incoming mains supply...

7 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 reser voir capacitors in the Klimax are about the size of a thimble but give better filtering than ones the size of a beer can used in other ...

9 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 manufacturers swear by Cla...

11 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. O u t p u t p o w e r s p e c i f i c a t i o n ( i ...

13 The compactness of the Klimax 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 a n d we i g h t .

14 Restricting the air flow by stacking the amplifiers or putting them in an enclosure may increase the operating temperature until the internal fan is switched on. This should only operate when the amplifier is being worked e n t h u s i a s t i c a l l y, o r h a s re s t r i c t e d ve n t i l a ...

15 The Klimax 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 as power is appl...

17 The Klimax contains two power supplies. The small, auxiliary one runs as long as the mains switch is on and power is present. It powers circuitry which detects the presence of an audio input signal, and the blue front panel LED. T h e s i g n a l d e t e c t o r i s ve r y s e n s i t i ve b u t ...

18 The Klimax has both single ended and balanced inputs, selected by a switch on the back panel. Use the appropriate one to suit your choice of preamplifier and cabling. LEDs indicate which input is selected. Both signals are echoed out the single ended ‘line out’ socket to enable daisy chaining of ...
