Line Voltage Selection
The ACOM 500S amplifier is supplied with built-in switching-mode power supply (SMPS).
The amplifier operates in an extended mains voltage range of 100-240 VAC, with no internal switch over. The
consumed current is purely sinusoidal, Power Factor Corrected (PFC) and inrush limited. This makes the
operation from unstable mains and generators easy and trouble free.
Thanks to the built-in SMPS, the ACOM 500S has no mains line voltage selector to take
care of!

Amplifier Location Selection
CAUTION
The unit's weight is about 8 kg and can be handled by a single person.
Position the amplifier near the place where it will be used. You will need an easy access to the command
knobs and indicator's area, as well as to the rear panel cabling.
NOTICE
The ACOM 500S is forced air cooled. Keep a minimum clearance distance of 10 cm
(4 inches) to any other devices or objects.
The exhaust air can reach 65
o
C (150
o
F) and if the surrounding devices are sensitive to heating from outside
or use forced air cooling themselves, increase the distances accordingly.
NOTICE
Do not leave accidental paper, cloth or other lightweight pieces around and under the
amplifier. They may be drawn in by the cooling air stream and block the vents. This will
lead to overheating and accelerated material aging, not covered by the warranty.
