LRx 3.1MT ECI - L Low Level: Pre-amplified Input/Output module
1_ L/R Ch Input: Preamplified
inputs for driving the main
channels Right and Left;
2_ BYPASS: Right and Left Preamplified
outputs. This output signal is not filtered. It
outputs the L/R input signals;
3_ CENTER Ch Input: Monophonic preamplified
input for driving the CENTER channel.
4_ SUB Ch Input: Monophonic preamplified input for
driving the SUB channel.

LRx 3.1MT ECI - H High Level: High Level Input/PRE Output module
1_ Left PRE OUT:
Left preamplified output.
This output signal in not
filtered. It outputs the L/R
channels Left input signal;
2_ L/R Ch Speaker Input: Amplified
signals inputs for driving the main channels
Right and Left;
3_ Out BYPASS (Speaker): Right and Left outputs. This
output signal is the main inputs signal;
4_ CENTER Ch Speaker Input: Amplified signal input for driving
the CENTER channel.
5_ SUB Ch Speaker Input: Amplified signal input for driving the SUB channel;
6_ Right PRE OUT: Right preamplified output. This output signal is not filtered.
It outputs the L/R channels Right input signal
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.

ECI module installation
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.
