How to power up your system
You should always power up your system the following way:
Signal sources (CD player, tuner,dac etc.) first. Then turn on the preamplifier.
Allow 30 seconds of preheating before you turn on the power amplifier. After
switching on the power amplifier, there will be a 5 seconds delay before the
speakers are connected. This will prevent large turn on/off transients to reach
the speakers.
When turning your system off, you should start by switching off your power
amplifier, then the preamplifier, and finally the signal source devices.
Warning
The product will be warm.
Due to the high class A operating point used in the Electrocompaniet design,
it is normal that the product feels warm. Proper ventilation will be needed, and
the product should not be covered. A good rule is to allow 1-2 inches of air
sidewise, and 2-3 inches above the product.
