Electrocompaniet EC4.6 - Manual (Page 6)

Operating instructions:
How to turn on your system
You should always turn on your equipment in this order: Signal source devices (CD, tuner,
etc) and preamplifier are turned on first. Allow 30 seconds of preheating before you turn on
your power amplifier.When turning your system off, you should start by switching off your
power amplifier, then the preamplifier, and finally your signal source devices
Warning:
The preamplifier will be warm.
Due to the high class A operating point used in the Electrocompaniet design, it is normal
that the preamplifier feels warm. Proper ventilation will be needed, and the preamplifier
should not be covered in. A good rule is to allow 1 - 2 inches of air sideways, and 2 - 3
inches above the preamplifier.
