K Series Active
Connection to the mains supply.
Before connecting the enclosure to the mains
supply, make certain that the current corresponds
with that indicated on the rear of the unit (there is
an allowance of ±10%). Always connect the power
cable to the enclosure
before switching on the
enclosure and always remove it
after having
switched off.
Switching on and off.
Remember to always connect or disconnect other equipment with the
enclosure off and to always switch on the mixer first, then the
enclosure: in this manner, annoying and often dangerous peaks are
avoided.
The SIGN/LIMIT LED may light up for a few moments when the mixer is
switched on.
Handling.
Dont force connector and knobs: they have been designed to respond
to a light touch and could be damaged if treated with excessive force
Connections and prevention or identification of possible
interference.
Above all, check that there is no industrial disturbance or radio
frequencies where the system is to be installed (if there are, consult a
reliable technician who will at least be able to give you some useful
hints on how to reduce them: mains filters, screening, etc.). In any case,
avoid installing your equipment in the vicinity of radios, televisions, etc.,
since this could cause noisy disturbance.
When connecting other equipment to your sound system, pay close
attention to so-called earth-loops, which can cause hum or interfere
with the enclosures excellent S/N ratio and low distortion.
The ideal method for avoiding earth-loops (even if not always practical)
consists in connecting the electrical earth of all the apparatus to a
central point (the star system). In this case, the central point of the
star can be taken as being the mixer. In the event of interference,
try using the SHIELD switch on the enclosures control panel: this can
often break earth loops, as it separates the electrical earth from that
of the units chassis.
For better identification of any disturbance however (at least when
installing for the first time), connect the various mixer sections to the
rest of the equipment in the following order and listen to the results
after each stage of the connection.
