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, 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, in terms of
sound 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 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).
