Casing

The KLIMAX CHAKRA 500 Twin’s casing is precision machined from two solid sections of aluminium alloy. The machining is carried out on a computer controlled multi-axis machining cent re, with the final cut on the top face made by a Swiss SIP vertical jig borer, the stability and accuracy of which is unequaled.

This compact, yet solid and heavy case, protects and stabilizes 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 accommodates the power supply and the other, the audio circuitry. This arrangement, coupled with the section of solid aluminium casing that separates them, very effectively isolates the audio circuitry from the power supply.

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.

The size of these components dominates the amplifier’s dimensions and affects the ‘tightness’ of the audio path, and if voltage regulators are present the power dissipation of the amplifier increases by up to 50%.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.
