  • Page 10: Introduction

    1. Introduction Thank you for buying the best power amplifier we have ever made. The result of years of experience, the Klimax uses the latest technology and exemplifies our constant endeavour to make ever better sounding products. We are confident that the compact, elegant design and the exceptional, accurate performance of the Klimax amplifier will give you many years of pleasure.

  • Page 11: What Is It

    2. What is it? The Klimax is a single speaker power amplifier designed for use in multi amplifier and multi channel audio and audio/video systems. The case is precision machined from two solid sections of aluminium alloy. The machining is done on a computer controlled multi-axis machining centre, with the final cut on the top face made by a Swiss SIP vertical jig borer, the stability and accuracy of which is unequalled.

  • Page 12: How Does The Klimax Work

    3. How does the Klimax work? In most power amplifiers the power supply comprises a large transformer, a rectifier and reservoir capacitors, often as large as the transformer. The highest performance amplifiers also have voltage regulators which maintain the power supplied to the amplifier circuitry constant, regardless of the input voltage or the output load.

  • Page 13: What Is Switch Mode

    Such a high voltage is very dangerous and is one reason why the Klimax case should never be opened by a customer or a non Linn Products employee. This high voltage is chopped up by very fast semiconductor switches and...

  • Page 14: So What's The Problem

    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 but still have to operate reliably in a very electrically hostile environment.

  • Page 15: Some Assorted Facts

    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 can used in other very powerful amplifiers.

  • Page 17: The Audio Circuitry

    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 manufacturers swear by Class A, others by Class AB, one or two by Class D, and many others are somewhere in between.
  • Page 18 The arguments about the relative merits of tubes, MOSFETS and bipolar devices have filled many technical journals, and needless to say, most are over stated and over simplified to try to win the argument! It’s possible to design a good amplifier using any of the available technologies. Turning it into a great amplifier takes more than just a good argument.

  • Page 19: Output Current And Protection

    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 specification (into 8 Ohms) can be increased simply by increasing the amplifier power supply rails slightly.
  • Page 20 This nagging doubt, though often ill-founded, has resulted in some concern (and boasts) about amplifier output current. The Klimax, like all Linn amplifiers, is specified into a 4 Ohm load. We don’t do this to claim a bigger output power, but to show that our amplifiers are intended and fully specified for operation into 4 Ohm loudspeakers.

  • Page 21: Installation

    4. Installation 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 and weight. The unique wall mount system can be used to minimise the intrusion of the audio system into the living space while providing good ventilation, concealing the cabling and showing off the subtle beauty of the Klimax.
  • Page 22 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 enthusiastically, or has restricted ventilation. If the ventilation is very restricted the amplifier will shut down until its touchable surface has dropped to a safe value.

  • Page 23: Mains Supply

    Mains supply 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 applied.
  • Page 24 Linn switch mode powered components can actually help to improve the sound of all the other components in the system.

  • Page 25: Signal Sensing

    Signal sensing 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. The signal detector is very sensitive but waits about one second before powering up the amplifier to be certain the signal was real, not just noise.

  • Page 26: Inputs And Outputs

    Inputs and Outputs 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’...

  • Page 27: Operation

    To operate the Klimax, select a source on your preamp, wait a couple of seconds for the Klimax to power up, then sit back and enjoy We wish you many happy years of listening pleasure. From the Linn Klimax team.
