PA2000 Series | Power Amplifier
Mains AC cord comes with standard British 3 pin plug with fuse. Please refer to the table at page 10 for suitable fuse
replacement.

The vent fan draws internally generated hot air and dispersed by the fan. The fan has dual speed which is determined by the
internal heat sink temperature. To allow proper cooling, please ensure that the ambient is properly ventilated.
9. VENT FAN
The sliding switch allows separation of body earthing from signal common to prevent hums noise.
6. GROUND LIFT SWITCH
Incoming signal to the unit is via 3 pin XLR female socket and the adjacent male jack is connected parallel for linkage to the
next unit.
8. INPUT JACKS
Output volume is adjustable from -15dB to 0 dB.

COOL AIR
The above diagram depicts the air flow pattern for the amplifier cooling system. Cool air intake is taken from outside via dual
speed temperature dependent fan. Several outlets of the warm air dissipations can be found in front panel, sides as well as top
cover.
Please ensure these vent holes are not blocked in order to keep the operating temperature at optimum. Allow a breathing space of
100 mm for each vent outlet.
For installation in rack, we recommend that internal rack ventilation fans are installed, one for cool air intake and the other for heat
dissipation.
The optimum operating temperature of the unit shall be kept at approximately 40 degree Celsius. The fan shall rotate at high
speed upon reaching the temperature of 45° at the transistor module.
