INSTALLING YOUR ME580
ME Amplifiers Melbourne, Australia
SPEAKER CABLING
It is always preferable to locate the amplifier as close as practicable to the speakers, and between them. Use
speaker cables of good quality and adequate wire size (thickness) and preferably which have been designed
for the purpose. Do not use hook up wire or light duty cable. Ensure that the cables are not excessively long,
and are of the same length for each channel. It is preferable to use good quality banana plugs at each end of
the speaker cables, ensuring that these are a good fit in the sockets on the rear panel of the ME580, and on
the speakers. If connecting the cables without using banana plugs, ensure that the bared ends of the cables
are twisted so that there are no loose strands, before inserting into the terminals and tightening firmly.
Always check to ensure that there are no loose strands of wire outside the terminals, as they could contact the
chassis of the ME580, resulting in a short circuit that could seriously damage your amplifier. Also ensure that
the cables are located in such a way that they are not likely to be accidentally pulled out of the terminals on
the speakers, or on the ME580. Damage may occur to your amplifier if this happens while the system is
operating, particularly at higher volume levels.
SPEAKER IMPEDANCE
Your ME580 is designed for use with loudspeakers with impedance in the range 4 – 8 ohms. Use of
some types of speakers with less than 4 ohms impedance may be possible, but is not recommended.
This is because the ME580 is fitted with current limiting circuitry that is provided to protect the
amplifier against serious internal damage that could otherwise occur when operating at high output
levels with low impedance speakers. In such circumstances, if the current limiting circuitry comes
into operation, degradation of the sound quality will begin to occur, possibly only at some
frequencies, but in severe cases across a wide frequency range. If this situation does occur, it does
not indicate a fault with the amplifier, and can be dealt with, at least in the short term, by reducing
the volume setting on your preamplifier.
INPUT LEADS (INTERCONNECTS)
For the connection between your ME580 and the preamplifier, use a good quality audio type lead fitted with
the correct type of plugs, depending on whether the balanced or unbalanced inputs are to be used. The
unbalanced inputs require RCA type plugs, and the balanced inputs require XLR plugs.
VENTILATION
The amplifier may be positioned within a cabinet or entertainment rack, as long as the cooling air from the
outlet air vents (located on each side of the ME580 towards the rear) is unobstructed. If it is installed within a
cabinet of reduced ventilation, the fan speed will automatically increase to counteract the higher ambient
temperature. Cooling air is drawn into the amplifier through an inlet grill with integral air filter, located
underneath the amplifier at the centre near the front. Ensure that air flow through this grill is not restricted in
any way, e.g. by placing objects under the ME580. Do not install the ME580 on a soft surface such as carpet,
as the weight of the amplifier may cause the feet to sink into the surface and reduce the clearance under the
air inlet grill, which will restrict airflow.
