rating be used, the limiter positions shown in brackets should be used as
indicated by the table on page 6 to increase the associated limiter thresholds.
Amplifier gain controls should normally be set at maximum. If a single
EMX1A output is used to drive several amplifier channels with different gain
settings, the sense input should be connected to the channel with the
highest setting.
WARNING: Connections to the EMX1A sense sockets should only be made
using approved shrouded plugs to comply with European safety standards.
No other plug is recommended or endorsed.

HIGH FREQUENCY EQUALISATION
System-specific high frequency equalisation is available to tailor the power
response of EM Series high frequency devices. Jumpers J6, J7 on the internal
PCB sets the HF EQ in or out, depending on the particular EM Series
loudspeaker system in use.
Recommended switch settings are as follows:
SYSTEM
HF EQ
EM15 J6, J7 IN
EM26 J6, J7 IN
EM56 J6, J7 OUT
EM76 J6, J7 OUT
The EMX1A is supplied from the factory with the HF Jumpers J6, J7, in the IN
position.

MONO SUB
A jumper link within the EMX1A (J5) may be positioned to mono-sum the
sub-bass signal. A mono left and right signal will then appear on both the
sub out XLR’s.
10
LEVEL ADJUSTMENT (TRIM)
The full-range output level is set at a nominal 0dB gain. To balance the
complete system, sub-bass levels can be adjusted by means of PCB
mounted trim controls accessed with a small screwdriver through the front
of the EMX1A.
