2.4 INSTALLATION ADJUSTMENTS
2.4.1 GAIN SELECTION
The gain of the balanced monophonic audio processing circuit on the AFC/PLL circuit board is selectable for
input levels ranging from 0.0 dB to +10 dB. The ME-40 is shipped from the factory for an input level of +10 dB.
If an alternate level is required, refer to Figure 2-3 and connect the appropriate resistor between terminals E1
and E2 as determined by the following information.
INPUT LEVEL RESISTOR VALUE

WARNING
DISCONNECT ALL SYSTEM POWER BEFORE PROCEEDING.
WARNING
2.4.2 WIRING
Refer to Figure 2-1 and connect a coaxial cable (located in the accessory kit) between the RF OUTPUT connector
on the exciter rear-panel and a 50 Ohm RF load capable of dissipating the output of the exciter. Refer to Figure
2-1 and connect the external signal inputs and remote control wiring as required. A second coaxial cable is
provided to connect an SCA or composite input to the exciter.
WARNING
THE EXCITER CASE MUST BE CONNECTED TO EARTH GROUND.
WARNING
