Installing the EFN

Because the ES 40 features the front accessible Extended Function Network, the amplifier does
not have to be opened, nor does it have to be removed from its rack to install the EFN circuits.
To (re)place the EFN board(s), switch off the amplifier and remove the EFN lid on the front of
the ES 40 and simply plug in the EFN modules. The upper one is intended for channel 1 or
bridge mode operation, the lower one is intended for channel 2. It should be noted that the
standard loudspeaker protection boards are not suitable for bridge mode operation! Make sure
you switch the adjacent switch(es) to the <ON> position, otherwise the EFN boards are
bypassed. Afterwards put the lid back in its original position.
