Chakra amplifier technology
The Chakra amplifier design uses an array of large transistors as ‘boosters’ around
a single chip integrated circuit. When output current is less than a few amps all
the power output comes from the single chip circuitry, maximising the speed and
linear properties of this design. At higher output currents the transistors provide
the majority of the output current, leaving the integrated circuit to operate well
within its capability and able to correct any error instantaneously.
The design is very compact, reducing the circuit area and length of the signal path
and is also highly efficient, producing much less heat than traditional designs.
Switch mode power supply (SMPS)
SMPS is an electronic power supply which converts and regulates the incoming
mains voltage, and also provides the internal audio circuitry with excellent
electrical isolation from the outside world. The SMPS replaces the bulky, heavy
and noisy transformer found in most amplifiers, as well as a number of other
sizeable components.
The major benefits of SMPS over conventional power supplies include: small
size, high efficiency, fast response, high mains input tolerance and, with its much
reduced material use, environmental friendliness.
Also, SMPS does not emit distortion into the local mains supply, as conventional
large power supplies tend to do. And if you upgrade from an amplifier with a
conventional power supply to the Majik-I amplifier, aside from the benefits of
the improved amplification, the sound of your entire system will almost certainly
improve as a result of the cleaner mains supply.
FEATURES
Aktiv* operation
Standard ‘passive’ crossovers are driven by the audio signal itself and so some of
the signal is effectively lost. Aktiv crossovers are powered by the SMPS (see left)
and therefore much more of the audio signal is delivered to the loudspeaker. They
are also able to exert a much greater degree of control over the signal and these
qualities combine to provide a significant improvement in sonic performance over
standard operation.
Your authorised Linn retailer can convert your Majik-I amplifier to Aktiv operation
with the insertion of a specially designed Linn Aktiv module.
Protection
Over-current protection
If the output current goes above the power amplifier’s designated safe operating
level, it shuts down instantly for a few seconds in order to protect itself and the
loudspeaker drive units to which it is connected.
Over-temperature protection
Similarly, if the amplifier’s temperature rises above its safe operating limit, the
amplifier will cease operation until the temperature drops to a safe level and will
then automatically resume.
* The term ‘Aktiv’ refers to the proprietary Linn active modules and loudspeaker
configuration.
