ECI module installation
Instructions are the same for both panels:
1_ Remove the screws indicated in the drawing;
2_ Remove the module by pulling it up, paying special attention not to bend the contacts
which are perpendicular to the amplifier;
3_ Replace the module with the one you want to use, or turn it with the contacts facing the
amplifier inside, in the direction you choose;
4_ Mount the module paying attention to the contacts;
5_ Insert the module until it is all the way into its socket;
6_ Fasten the screws making sure you don’t force them.
When mounting ECI in reverse
A label is placed under the amplifier, near the input module, indicating the correct connections
and configurations.

ECI-H Easy Common Interface - High Level
ECI – Easy Common Interface Modules
The LRx amplifier input section is totally new. Audison created ECI, an interchangeable
interface module that is very easy to use. There are two different modules and you can
choose what type of signal input to use to drive the amplifier. These modules are also reversible,
enabling you to run the input cables underneath the amplifier through special recesses in the
amplifiers bottom plate. Special cable guide clips are provided to fix the cables. This is very
useful for tight installation spaces where you do not have the room to have cables protruding
past the amplifier chassis. A label indicates the correct layout and function.
