CONNECTION TO THE MAINS
The connection of the graphic equaliser to the mains takes place by means of a three-
wire I.E.C. cord provided by the factory. The European standard color code is: Brown-Live,
Blue-Neutral and Yellow/Green-Earth, keeps in mind this mains configuration, whenever
handle the graphic equaliser plug.
Make sure that the graphic equaliser power switch, is at position 0
(turned off).
Insert the female I.E.C. connector plug into the graphic
equaliser male connector, placed at the rear panel.
Insert the male connector plug into the mains socket.
Turn on the graphic equaliser power switch. In that mo-
ment the range switch indicator will light, indicating that
the graphic equaliser is turned on.
CAUTION:
Make sure that the mains voltage and the fuse ratings are
correct.
INPUT CONNECTION
The graphic equaliser input signal, is carried out through two XLR-3-31 female connec-
tors, one per channel. The input connections are balanced, with a nominal impedance of
20 K
Ω
(10K
Ω
unbalanced).
The next pictures shows some of the different possibilities of connection, relying on the
type of input signal, balanced or unbalanced and according to the ground configuration of
the equipment (floating or ground-referenced).
NOTE:
The equipment is considered floating, when the earth mains is lifted (is to say has a
mains plug of this form: ), or when it is lifted the electrical ground of the unit from the earth
mains (is to say, with the EARTH-LINK switch in OFF position:
).
UNBALANCED INPUT: This type of connection will be used when the sound source doesn't
provide balanced output. If it possible, will be employed the connection type 1.
