4. OPERATION AND USAGE

4.1. Start up

To switch the unit on just push the switch labelled POWER (19) and the integrated pilot-light will
light up. We highly recommend the "safe power-up sequence": First the sound sources, then mixer,
equalizers and active filters and, finally, power amplifiers. Powering off should be done by following the
exact reverse sequence in order to avoid any possible peaks reaching the next device, and
consequently protecting the loudspeakers, which are specially sensitive to these peaks.
NOTE: Fully disconnecting the device from mains is done unplugging the power cord from the
mains input socket (50). For this reason, it always shall remain readily operable.
