Information regarding use of the P1200A mainframe
The mainframe complies with the electromagnetic compatibility
requirements of EN 50082-1 - residential, business and commercial
areas.
Acoustic interference and malfunctions may occur if the unit is
operated in the immediate vicinity of high-frequency transmitters
(e.g. wireless microphones, mobile phones, etc.). Damage to the
mainframe is unlikely, but cannot be excluded.
To meet the EMC requirements, use only shielded cables with
properly connected plugs for all signal terminals (INPUT, INPUT
LINK, MONO OUT).
The following information is intended to prevent fires and possible
electric shocks:
The mainframe is a protective class 1 unit. Make sure that the earth
(ground) contact is attached when the unit is in operation. A missing
earth (ground) contact may lead to dangerous voltages in the
housing and controls.
To reduce the possibility of audible hum the mainframe signal
ground (XLR pin 1) to earth (ground) connection has a high
impedance. It will prevent the unit from static charge but any
voltage applied to signal ground will pass through all connectors.
To prevent electric shock, make sure that all devices in the signal
path are grounded properly.
Never connect an amplifier output pin to any other in- or output
connector pin or earth (ground). This might damage the mainframe
or lead to electric shock.
Lay all cables to and from the unit so that they cannot be crushed
by vehicles or other equipment and that no-one can step on them.
Keep dust, moisture, water or other liquids well away from the unit.
Never operate the unit when it is open.
Always disconnect the mains power supply when replacing a
defective fuse. Only use the type of fuse listed in the specifications.
