PROTECTION
The EVOLUTION 50A has short circuit (over-current), over-temperature and DC offset
protection. The internal loudspeaker relay will isolate the output under any of these condi-
tions and the display will indicate the cause. The loudspeakers will be re-connected after
a delay as soon as the fault has cleared. If the over-temperature condition has occurred
then please check the amplifier has adequate ventilation and that there are no faults with
the loudspeaker wiring. Likewise, if the over-current protection has been activated then is
highly likely there has been a short circuit of the loudspeaker wiring so please switch off
the amplifier and check the wiring before continuing.
The 'DC presence' warning is either due to an internal fault with the amplifier or can some-
times be triggered by severe clipping (overload) of the amplifier. If the condition clears by
itself try reducing the volume setting. Never drive your amplifier to levels which cause obvi-
ous distortion to be heard. This is an indication that either the amplifier or loudspeakers are
being pushed beyond their capabilities and can result in permanent damage.
POWER CONSUMPTION
It is appreciated by hi-fi enthusiasts that leaving equipment powered up continuously can
improve the performance. However, this small improvement in sound quality comes at the
expense of continuous power consumption from the mains, which will increase your elec-
tricity bill and also reduced working life of the product. The EVOLUTION 50A draws 20
Watts of power when switched-on and not producing a signal.
We recommend switching the EVOLUTION 50A off at the front panel if the equipment is
not to be used for a period of time. Normal performance is achieved in a very short period
of time due to the advanced circuitry in your EVOLUTION 50A amplifier.
Relays are used to route signals inside the EVOLUTION 50A and these produce a me-
chanical click sound when they operate, this is normal and does not indicate a malfunction
with the product.
