> PRINT GUIDES To change the mains voltage, remove the rectangular fuse cap and replace it so that the correct voltage is indicated by the arrow on the body of the rectangle. The earth terminal on the IEC connector is permanently connected to the metal casing. The unit is supplied with the 0V electronic reference ground taken to the case via an internal ‘signal ground’ lead and space receptacle, which inserts a ground lift resistor when in the ‘Earth Off’ position.
5 > PRINT GUIDES OUTPUT CONNECTIONS EMX2A outputs are electronically balanced auto compensating via male XLR type connectors. Pin 1 is the (ground) connection and the signal appears between Pins 2 and 3. Always use 2-core + screen ‘balanced’ type signal leads, even for unbalanced circuits. The screen should be regarded as separate from the signal return, even if they are connected together at one end of the line.

< > PRINT GUIDES Each EMX2A output has an associated limiter which provides momentary gain reduction when that output signal level exceeds a preset threshold. Internal PCB mounted jumper plugs J1 - J6 select the thresholds for the particular EM Series loudspeaker system being used. Note: As supplied by the factory, jumper links J1-J6 are each set in the appropriate position for the EM186 full-range system and EM201 sub-bass powered with the recommended rating below.
8 > PRINT GUIDES HIGH FREQUENCY EQUALISATION System specific high frequency equalisation is available to tailor the power response of EM Series high frequency devices. A PCB mounted slide switch switches the HF EQ in or out, depending on the particular EM Series loudspeaker system in use. Recommended switch settings are as follows: SYSTEM EM186 HF EQ IN The EMX2A is supplied from the factory with the HF EQ switch in the IN position.
