Operating
All functions of the HUMBOLDT are microprocessor controlled. This guarantees
highest precision, exclusive functions, easy handling and protection against oper-
ating errors.
6.1
Powering up
First of all, please make sure your HUMBOLDT is connected correctly to your
signal sources, speakers and mains power (refer to sections 'Installation and
power supply' on page 11 and 'Inputs and outputs' on page 13).
The HUMBOLDT is a stand-by unit. Please insert the power cord into the mains
input socket on the back panel and connect the HUMBOLDT to mains power.
The display shows a welcome message for a brief moment. After that the
HUMBOLDT is in stand-by mode. The display turns dark now.
The HUMBOLDT should only be switched off from the mains in cases of ex-
tended absence (like vacations) or if massive trouble on the mains power is to be
expected. Pull the mains plug off the mains input socket to completely discon-
nect the unit from mains.
Important
Never pull the power cord while the HUMBOLDT is up and running!
Before you disconnect the power cord, always power the unit down to stand-
by mode first.
If you disconnect the HUMBOLDT from mains power, first power down and
completely discharge all units connected to the outputs of the HUMBOLDT
first.
