Signal Input
This combined XLR 6,3mm jack socket serve as input for the audio signal. There is also 1 parallel output for
connecting an active loudspeaker system or an additional power amp.
Mains Switch
Do not supply power before the whole system is set up and connected properly.
Connection Cables
Take care of the connector cables, always holding them by the connectors and avoiding knots and twists
when coiling them: This gives the advantage of increasing their life and reliability, which is always to your
advantage.
Periodically check that your cables are in good condition, that they are correctly wired and that all their
contacts are perfectly efficient: a great number of problems (faulty contacts, ground hum, discharges, etc.)
are caused entirely by using unsuitable or faulty cables.
