The E-9 module is a Hi-Fi power stage with direct connection, without output capacitor. It could offer 180 W.
as maximum power. Its mains characteristic its high quality as well as its reduced distortion. It includes
protection against output short-circuits and connection terminals.
Because all the following information is very important to obtain a correct module operating, we
recommend you to completely read the instruction manual.

OPERATING.
MODULE 'S SUPPLYING.
stabilised, for this reason we suggest you to not use simple supply equipments neither rectifiers, which could
negatively affect the module's operating , but a power supply.
We recommended you the FS-9 power supply which has been developed to perfectly answer to the circuit
needs. Connect the positive, the negative and zero of the power supply to the corresponding terminals
indicated in the schedule. The distance between power supply and module have to be as short as possible
(15 cm as maximum.) Verify that the assembly has been correctly done.
To obtain a correct module's operating we suggest you to protect is against mains interference, to do that you
have to place between the mains and the transformer a filter (See the paragraph "Installation of the Filter").
OPERATING.
See the paragraph "General wiring map". When the connections of the power supply are made,
install a loudspeaker to the indicated terminal. The loudspeaker must to be 200 W (as minimum). Nevertheless,
we suggest you to place a loudspeaker with 220 W. (as minimum power). If you use quality loudspeaker, you
could highly appreciate the assembly.
INPUT SIGNAL.
The input signal could be supplied by auxiliary devices as mixing desk, etc... but this input
could not exceed 700 mV. Connect input terminals indicated in the schedule, and the distance between
module (power stage) and its signal supply, has to be as short as possible. Use shielded cable for this assembly.
PROTECTION AGAINST SHORT-CIRCUITS.
is enough to allow you to disconnect the power stage. If this time is higher, loudspeaker of the module could
be damaged.
INSTALLATION.
It is obligatory to install the power stage in vertical position, to avoid to damage the operating
and/or the module. To install the power stage, we suggest you to fit it into a metallic box. This last has to be
enough stronger to include module and its power supply as well as well ventilated. Indeed, during its operating
the module will heat. Connect the ground to the box chassis.
The E-9 module had to be supplied by symmetrical voltage +/- 42 VDC, correctly
The protection against output short-circuits is only 30 sec. This time
