- Page 2 Each KLIMAX CHAKRA 500 Twin power amplifier is unique in its manufacture.With its machined and hard- anodised solid casing, the KLIMAX CHAKRA 500 Twin is a referenced component which is as individual in its finish as it is in its phenomenal pitch-accurate performance.
- Page 3 MAINS PLUGS This appliance is supplied with a non-rewireable mains plug for the intended country. Replacement mains leads can be obtained from your Linn retailer. Should you need to change the plug please dispose of it carefully. A plug with bared conductors is dangerous if engaged in a live socket.

Page 10: Introduction
Put simply, this is the finest 2-channel power amplifier Linn has ever made and we are confident that the KLIMAX CHAKRA 500 Twin will give you many years of listening pleasure which will grow over the passage of time. -
Page 11: Features
The compact form of the KLIMAX CHAKRA 500 Twin case reflects our intention to keep the audio signal path as short and simple as possible. Applying this rule rigorously results in high density circuitry which... -
Page 12: Power Supply
Features Power supply In most power amplifiers, the power supply comprises a large transformer, a rectifier and reservoir capacitors, which are often as large as the transformer itself. The highest performance amplifiers also have voltage regulators which maintain the power supplied to the amplifier circuitry at a constant level, regardless of the input voltage or the output load. - Page 13 CHAKRA 500 Twin it can deliver 1000 watts (at 50/60 Hz it could deliver only about 5 watts). The reservoir capacitors in the KLIMAX CHAKRA 500 Twin are about the size of a thimble but give better filtering than ones the size of a beer can that are used in other very powerful amplifiers.

Page 14: Audio Circuitry
For a number of years, Linn has worked closely with a trusted microchip manufacturer and as a result of developing this relationship, exceptional capability has been designed into a high-volume chip, enabling us to realise the potential of this technology without incurring unfeasibly high production outlay. -
Page 15: Chakra Explained
The CHAKRA topology uses an array of large bi-polar transistors as ‘boosters’ around a single monolithic. While this in itself is not a new idea, Linn’s execution of the monolithic to bi-polar transition is unique, and a patent application for the design has been submitted. When output current is less than a few amps, all the power output comes from the monolithic, maximising the speed and linear properties of this design. - Page 16 This nagging doubt, though often ill-founded, has resulted in some concern (and boasts) about amplifier output current. The KLIMAX CHAKRA 500 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 (and most Linn loudspeakers have a nominal 4 Ohms input impedance).

Page 17: Installation
Installation The compactness of the KLIMAX CHAKRA 500 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 in the living space, while providing good ventilation, concealing the cabling and showing off the subtle beauty of the KLIMAX CHAKRA 500 Twin. -
Page 18: Mains Supply
Mains supply and output power For all normal music or AV system operation the actual 'average' output power of the KLIMAX CHAKRA 500 Twin is much less than its maximum rating of 200 watts per channel, thus providing an abundance of headroom. For example, a reasonable listening level requires an average output of about 1 watt per channel and a very enthusiastic listening level would average about 40 watts per channel. -
Page 19: Inputs And Outputs
Inputs and outputs The KLIMAX CHAKRA 500 Twin has both unbalanced and balanced inputs, selected by a switch on the back panel. Use the appropriate one to suit your choice of pre-amplifier and cabling. The LED will light to indicate when the unbalanced inputs are selected. -
Page 20: Operation
Signal sensing In the absence of a music input signal, the KLIMAX CHAKRA 500 Twin reverts to a low power standby mode after around 20 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. -
