Connections and controls
The female 3 pin XLR3 connector INPUT (1) must be connected to the power supply unit, to the master station or to the
male 3 pin XLR3 connector LINK (2) of another remote station. The headset must be connected to the 4 pin male XLR4
connector (3) . The stations are designed for use with low impedance (600
Ω
nominal) unbalanced dynamic micro-
phones and high impedance (100 ÷ 1000
Ω
) unbalanced headphones.
For connection to the remote stations, it’s possible
to use standard microphone cables (2 conductors +
screen) (9) , in case of very long connections we strong-
ly suggest to use a 3 conductors + screen cable, having
at least 0.18 mm2 conductors, using the third conduc-
tor to connect the XLR connector’s body (frame) (10).
Max cable length may be more than 500 m, if cables
with large conductors and good screening are used.

The MIC on/off switch (4) allows the microphone to be switched on and off. It is suggested to switch the microphone off, if not used, to reduce unwanted noise in the intercom
line. The green LED is lighted when the microphone is on. The rotary VOLUME control (6) adjust headphones listening volume. The screwdriver adjustable SIDE TONE trimmer
(7) adjust the level of the local microphone returned to the station’ s headphones. This control does not affect the microphone signal sent to other stations. In the center position
the microphone level (return) is kept to a minimum, but if the control is rotated clockwise or counterclockwise the microphone signal is returned to the headphones amplifier
with adjustable level and phase. Some users prefer to hear their own microphone’s signal for being sure that it’s operating. By pressing the CALL button (4) a call signal is sent to
all the stations connected to the same intercom line. The CALL lamp on these station flashes. The BUZZER switch (5), when set to the LO and HI position, enables the acoustic call
signaling, and adjusts the buzzer volume, to low (LO) or high (HI) level. If the buzzer is on, the yellow LED is lighted. In the OFF switch position, the buzzer is disabled.
