4.4. Mains Supply
Be sure you got PA with properly terminated line cable, corresponding with your
power system’s outlet. If not, contact your dealer. In such a case you should make the
necessary changes using a licensed electrician.
Be sure that your power system is correctly wired and properly rated! To use
adequately sized and connected grounding system is also very important.
4.5. Cooling
The amplifier must be installed in such a way that free flow of hot air from the tube is
allowed. Do not obstruct air intake and exhaust areas of the PA.
The centrifugal blowers provide the necessary cooling of the amplifier, even during long
contests. The main blower is activated by switching the PA on and it is turned off when cooling
is finished (approx. 1-5 min after switching off the PA depending on the temperature of the
tube). The supplemental fan is turned on depending on the temperature of the air exiting from
the amplifier. It is switched on at 70°C and switched off at 60°C.
4.6. Remote Control
Control of the amplifier is possible remotely by using
REMOTE BOX (optional). Connection
is done by REMOTE socket, maximum cable length of 10 meters.
