THE LINN PERFORMANCE ADVANTAGE
For more information on the performance advantages of bi-wiring, tri-wiring, passive bi-amplification, and
AKTIV multi-amp systems, consult your local authorised Linn retailer.
AMPLIFIER OVERLOAD PROTECTION. There are two levels of electronic protection in the POWERTEK.
One is an over-current sensor, which protects against short circuits or very low impedance loads. The
other is an over-temperature sensor which protects against inadequate ventilation. The internal
temperature sensor will shut the amplifier down if the sensor reaches 70 degrees centigrade.
To re-set, switch the POWERTEK off for a few minutes and then switch it back on. The amplifier will have
re-set itself and will resume working normally.
LOAD IMPEDANCE. The POWERTEK will drive two pairs of 8 ohm loudspeakers, or one pair of 4 ohm
loudspeakers without any problems. Two pairs of 4 ohm loudspeakers may cause the over-current
protection trip to operate at moderate volume levels. However, no combination of loudspeakers will
cause damage to the POWERTEK.
