GETTING TO KNOW YOUR ME580
ME Amplifiers Melbourne, Australia
Speaker Cables may be bared and twisted, then inserted into the holes in the sides of the terminals
before tightly screwing down the terminal covers. If using this method, make certain that all bare wire
strands of the Speaker Cables are contained within the terminals, as even one stray strand of wire
could cause a short circuit between a Speaker Cable and the chassis of the amplifier. Also verify that
none of the Speaker Cables can make electrical contact at any point with the chassis of the ME580 or
any other chassis (e.g. CD player chassis). Also ensure that a short circuit between the red (+) and
black (-) terminals of either channel cannot occur. Finally, check that you have connected the speakers
to the amplifier with the same polarity on both channels, i.e. ensure that the wires from the red (+)
terminals on each channel of the ME580 go to the corresponding (red or +) terminals on both left and
right speakers. If the speaker wires are connected the opposite way round on one speaker compared
to the other, the speakers will be “out of phase” resulting in a loss of stereo image.
5. Connect the ME580 to a power point and switch the power point ON. The ME580 will then perform a
one minute initial power up self test, as detailed below. During the self test the ME580 amplifier
cannot be switched on; i.e. pressing the POWER pushbutton will have no effect.
Initial Power Application Self Test
•
The ME logo on the front panel escutcheon will be illuminated in Mauve light, the Temperature
Light labeled TEMP will be illuminated in Amber and the Status Light labeled FAULT will
illuminate Red indicating that the amplifier has mains power applied to it, and the cooling fans
will come on and be ramped up in speed to a maximum over a ten second period.
•
At the end of the ten second period the TEMP light and the FAULT light will turn off but the fans
will continue to run at maximum speed for a further 40 seconds to allow verification of airflow
from both heat sink air exhaust ports, and the ME logo will remain illuminated in Mauve light
indicating that the amplifier is still in self test mode. After the 40 second airflow test time the fan
speed will be ramped down to zero over a ten second period, and the ME logo will be illuminated
in Amber light, indicating that the self test is complete and the amplifier is in Standby Mode.
6. Press the POWER button located in the centre of the front panel escutcheon. The illumination of the
ME logo will change from Amber to Blue, indicating that the amplifier is ON, and is operational. Music
reproduction will be possible now. For the first minute or so, the sound quality may be slightly
reduced until the amplifier begins to warm up; this is normal, and generally more pronounced when
very cold and less noticeable if the amplifier has been used within the last 30 minutes. After several
minutes, the Green TEMP light on the front panel escutcheon will come on, indicating that the
amplifier is operating within the normal temperature range. When this condition is reached, the
sound quality will be at its best. The time taken for normal operating temperature to be reached will
depend on ambient temperature and the volume setting, as well as the load impedance of the
loudspeakers being used.
Please Note:
The ME580 amplifier can only be switched on ONCE per minute. This means that if the
amplifier has been switched on for less than one minute and is then switched off, it cannot be
switched back on until the first minute has elapsed. If the amplifier has been ON for over one minute
it can be switched OFF and immediately may be switched ON. This feature is to reduce stresses caused
by repeated rapid cycling between OFF and ON. If the amplifier is switched OFF before one minute has
