1. Introduction
Thank you for buying the Klimax Twin, the second member of the Klimax amplifier family and the best
amplifiers we make. Like the Klimax Solo the Klimax Twin 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 Twin will give you many years of pleasure.
If you wish to know more about this special product, read on. If you just want to use it now, go to the

2.What is it?
The Klimax Twin is a two channel 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.This compact
but massive case protects and stabilises the internal electronics and forms the heat exchanger to dissipate
the power from the amplifier circuitry. Inside the case are two circuit boards, one on each side of the central
heat exchanger. One circuit board constitutes the power supply, the other the audio circuitry.
The compact form of the Klimax case reflects our intention to keep the audio signal path as short and
simple as possible.This applies as much to a turntable pickup arm as it does to a power amplifier. Applying
this rule rigorously results in high density circuitry which generates and receives the absolute minimum
level of electrical noise. All our previous power amplifiers have been as compact as the available technology
permitted, but in the Klimax Solo we took a significant step forward with the new power supply that makes
the Klimax Twin possible.
If you just want to enjoy your Klimax Twin system right now, jump past all the technical material about to
follow and go to the 'operation' section.

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.The bulk of these components dominates the size of the amplifier and the
'tightness' of the audio path, and if voltage regulators are present the power dissipation of the amplifier
increases by up to 50%, requiring a bigger heat exchanger.This conventional type of power supply is simple,
reliable, tolerant of overload and predictable. On the down side it is very bulky, heavy, slow to respond,
inefficient, causes high mains power distortion, can cause electrical and acoustic noise and requires a
relatively long and exposed audio path.
In the Klimax amplifiers we use a technology we have been developing and using in our low power
products for several years, called 'switch mode'.This concept is not new; it has been used in computers since
the 1960's, however applying it to audio has always been considered, at best, inappropriate.The potential
benefits of switch mode power supply technology are compactness, high efficiency, fast response, good
mains input tolerance, good load tolerance, low acoustic noise and with its low material use, environmental
friendliness.The potential downsides are electrical noise, high complexity and potentially lower reliability,
complex certification requirements, design difficulty and high engineering cost.These have kept switch
mode out of most audio equipment.

What is switch mode?
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. 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 applied to a small transformer
which both transforms the voltage to the value needed by the electronic circuitry and provides a safety
isolation barrier from the mains supply.The size of a transformer reduces as its operating frequency
increases, so a transformer operating at say 60,000 cycles per second is far smaller than one operating at
mains frequency of 50 or 60 cycles per second.
On the output of the transformer, very fast rectifiers, a small coil and small capacitors filter and convert the
high frequency waveform back to dc, ready for the electronic circuitry to use. By controlling the timing of
the switches the output voltage can be held constant or varied, as required, without the need for further
inefficient voltage regulators.This processing all happens well above the range of human hearing which, in
principle, should be good for audio circuitry.

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.We have been designing and building switch mode supplies for our CD
players, tuners, preamplifiers and multiroom components for several years and can now make them more
reliable than the conventional transformers they replaced. But this takes persistence, thoroughness and a
very consistent high quality manufacturing process.
The second problem, which is what stops most manufacturers considering switch mode for audio, is the
potential high frequency electrical noise, or more precisely, preventing the high frequency signals becoming
electrical noise.The scale of the problem is quite daunting.The high frequency signal applied to the
transformer if connected to an external antenna would obliterate radio reception for miles around (please
don't try this at home!).This must be controlled and reduced so that it not only meets international legal
regulations but it must also not cause any audible or measurable interference with any of the audio
circuitry.This does not happen by accident, but takes experience, thorough precision engineering and
diligent quality control. Only when all of this is achieved can the potential audio benefits of switch mode
start to be revealed and exploited.

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.
The semiconductor switches turn on and off in about 20nS (20 one thousandth millionths of a second).
The overload protection for the switches can detect a potentially destructive condition and protect the
switches in less than half a microsecond (half of one millionth of a second).
We have patent protection for one of the innovative noise control techniques that are used.

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.Two designs can use
the same components, but achieve completely different results.We believe, and have evidence to support,
that what you do with the parts and technology is always much more important than the name of the
technology.To illustrate this, our current power amplifier range contains MOSFET, monolithic, discrete and
bipolar designs. Our latest monolithic designs sound better than our previous discrete bipolar designs. Our
latest bipolar designs have more power and sound better than our earlier monolithic and bipolar designs.
So what did we choose for the Klimax Twin?
For several years we have been designing and building power amplifiers using monolithic (single chip)
power devices.These chips contain all the audio circuitry of a power amplifier in a few square millimetres of
silicon, and in principle are the ideal way to manufacture a power amplifier.
The high investment and technology required to design and manufacture these chips means that they are
targeted at high volume applications where audio performance is not the most important parameter.
However, we have worked closely with a chip manufacturer whose power amplifier chip designer is also a
keen audiophile. He has designed into a high volume chip tremendous capability, which can be realised by
careful attention to detail and the appropriate circuit topology.The power output stage of the chip uses
MOSFETs, and the high level of integration includes the complex linearisation circuitry required for low
distortion from a MOSFET based design.

To achieve the performance and power output we use three chips per channel, and like the Klimax Solo the
Klimax Twin is direct coupled with no capacitors in the signal path. Combined with a slightly modified
Klimax Solo power supply we have achieved, as we know you will hear, true audiophile performance.

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. But what then happens with a 4 Ohm load ? Can the amplifier now supply the extra current a 4
Ohm load needs or will the power supplies collapse, or will the amplifier need to protect itself?
Short circuit protection can be achieved simply, but at the cost of accidental operation when the
loudspeaker load is reactive (almost always) rather than purely resistive (almost never).
Output current and ruggedness can be increased with the cost of paralleled output transistors, but can the
driver circuitry cope?
Hence the interest in output current. However the implication that 'more is better' is true only up to a very
modest and calculable limit. An electrical load, be it a resistor, capacitor, inductor, heater, a loudspeaker or a
hairdryer takes an amount of current dependent on the voltage applied to its terminals, and its operating
condition. Although it is not always entirely obvious how much current a load will take with a non-
sinusoidal signal (like music) its maximum possible value is easy to calculate, and to monitor in real
operation. If an amplifier can provide this amount of current into the specified load while keeping safe and
stable and not suddenly dropping its output voltage, it is enough.The load cannot draw any more.The
current draw is the result of the voltage applied.
If an amplifier protects itself by 'current limiting' it will drop its output voltage if too much current is
demanded.This is a bad thing for an audio amplifier, but not uncommon. If the current limiting never
operates under real conditions it is both a harmless and a good way to protect an audio amplifier.The
problem can then be to know if the protection ever triggers or not.This nagging doubt, though often ill-
founded, has resulted in some concern (and boasts) about amplifier output current.

The Klimax Twin, 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. Most Linn loudspeakers have nominally 4 Ohms input impedance.
The Klimax Twin has a simple decision making protection circuit. Either the output current is safe or it's not,
in which case the amplifier is shut down instantly for a few seconds. An unsafe output current is defined as a
level of current above a threshold for a length of time, or an instantaneous current above an absolute
threshold. If neither of these conditions are violated the amplifier is delivering all the current requested by
the load. It's very e

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 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.
Heat
The Klimax Twin is a very powerful amplifier. Unfortunately, despite the efficiency of the design it must still
dissipate considerable power. It has two methods of cooling; natural convection and forced air convection.
Both require an ample supply of air for ventilation. Natural air convection cooling operates for all normal
listening conditions by the heated air rising vertically through the central heat exchanger.
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.This is to meet international safety
regulations, not to protect the circuitry which can operate reliably with the case very uncomfortably hot to
touch.
13
Download from Www.Somanuals.com. All Manuals Search And Download.
When operating, the fan draws cool air in through the back of the amplifier, and blows it along the heat
exchanger until it exits through the front, top and bottom.
The amplifier is fully protected against over heating, but this is only for protection and should never operate
in normal use, whatever your 'normal use' is. If you only ever listen at moderate level, you may never notice
the temperature rise above idling.The high thermal mass of the case absorbs short periods of high power
input with a slow and low temperature rise and the natural convection through the heat exchanger
transfers this to the air. However, the last thing you want is for your audio system to shut down if you are
having a party. So always ensure the installation provides plenty of ventilation.

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 as power is applied.
For all normal music or AV system operation the actual 'average' output power of the Klimax Twin is much
less than its maximum rated power. For example, a reasonable listening level needs an average output of
about 1 Watt. A very enthusiastic listening level would average about 40 Watts output, per channel.With
most loudspeakers this would give an SPL of between 100dBA and 110dBA, which is quite loud.Very few
loudspeaker drive units (or crossovers) can stand the maximum continuous output of the Klimax for more
than a few seconds. A tweeter can take it for a fraction of a second, then vapourises. All this means that
even though the 'on the laboratory bench' measurements could show an input power of almost 1000 Watts
with a constant tone input and full rated power, in operation the input power is never anywhere near this
level.The Klimax Twin is a high fidelity music playing amplifier, not an industrial servo motor drive amplifier
or an arc welder. Given adequate ventilation it will operate continuously in any music or AV system at any
realistic power level. But with a low mains supply, maximum load and a signal generator on its input, the
mains fuse will blow because 100 V and 115 V mains supplies cannot provide enough power to sustain
continuous maximum output power.
If it really bothers you that you may not simultaneously be able to melt every drive unit in your loudspeaker
system, not to mention your ears, then lay in a 230 V mains supply just to provide power to your Klimax
system.You may want to consider this for the quality of mains supply rather than only for maximum
theoretical power. If you are going to this effort, consider making the new wiring operate at 200 V (Japan) or
230 V (USA). Obviously all mains wiring must be professionally installed to satisfy the appropriate local
standards. One of the benefits of the Klimax switch mode power supply is its tolerance to mains supply
quality, and the much lower damage it does to the incoming mains supply. Contrary to popular belief, a big
audio amplifier does a lot more damage to the mains supply than anything else in your house, and the
mains distortion from the power amplifier can cause other audio components grief.

Fitting in separate mains wiring spurs for the sources and power amplifiers is not to isolate them from the
mains distortion present in the rest of the house; it's to reduce how much of the mains distortion from the
power amplifiers gets into the other audio components in the system! Linn switch mode powered
components can actually help to improve the sound of all the other components in the system.

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 been found over many
installations to be a good compromise between sensitivity to low level signals and immunity to noise.
However, the residual hiss level from phono preamplifiers at moderate volume settings can be enough to
trigger the signal sensor. Mute the preamplifier or turn the volume down after use to prevent this
happening. If there is audible hum from the loudspeakers then you may have enough noise present to
trigger the signal sensor. Always try to eliminate the source of the hum, as this is essential for a system to
sound its best.

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 out' socket to enable daisy chaining of
amplifiers.This switch does not directly pass the audio signal but instead sends a control signal to
distortionless solid state switches.
The standard output connectors are two Neutrik 4 contact speaker sockets.They each have two 'hot' and
two 'cold' connections making it easy to connect two speaker cables per connector.The Neutrik part was
chosen for its high quality and connection integrity, compactness and international safety approvals.The
Klimax Twin is also available with high quality binding post connections.

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 a few seconds and dim the light.There is no
half way current limiting; the amplifier can either do what is required of it or it will shut down entirely.The
amplifier will revert to standby 10 minutes after the input signal is removed.To operate the Klimax Twin,
select a source on your preamp, wait a couple of seconds for the Klimax Twin to power up, then sit back and
enjoy it.
We wish you many happy years of listening pleasure.
From the Linn Klimax team.
