Connectors and controls
The IEC 3 pin mains connector (2) is the mains power input.
The mains POWER switch (3) switches the unit on and off.
The on LED (4) is lighted when the unit is powered on.
The short LED (5), when lighted, indicates a short circuit in cable connected to the output connectors (usually between pins 1 and 2 ).
The rear panel connectors (male 3 pin XLR) LINE A e LINE B (1) are connected to the remote intercom stations.
Each line’s two connectors are wired in parallel.
The two intercom lines are indipendent (split) or joined (common) according to the front panel LINES switch (8).
The front panel connector (male 3 pin XLR) (9) may be used to connect a beltpack station, used as a master (11),
that may be connected to the A or B intercom line using the front panel TALK TO switch (9).
If the lines are interconnected (common), this station will be always connected to both lines, for any setting of the TALK TO switch (9).
CALL A (6) and CALL B (7) LEDs flash to indicate that a station on the corresponding line has sent a call signal.
For connection to the remote stations, it is
possible to use standard microphone cable ( 2
conductors + screen) (12) , but, in case of very
long connections we strongly suggest to use a 3
conductors + screen cable, having at least 0.18
mm2 conductors, using the third conductor to
connect the XLR connector’s body (frame) (13).
Maximum cable length may be more than 500
m, if cables with large conductors and good
screening are used.
