ATTEN: when ATTEN is pressed, a dB reduction equal to the
“Attenuation” value set in the control software is applied to the

X2 input. Analog, Microphone and Tone Gen are available.

15.3 LEVELS SECTION
The levels section shows the Macrotel X2 Input and Output levels of both telephone lines of
each hybrid. The Operative Mode area shows whether the Macrotel X2 device is operating in
SINGLE mode, i.e. used as telephone hybrid for each single telephone line, or in
CONFERENCE, i.e. sending to Telephone Hybrid 2 (send) what is received from Telephone
Hybrid 1 (receive) and sending to Telephone Hybrid 1 (send) what is received from Telephone
Hybrid 2 (receive). The CONFERENCE mode allows the two interlocutors to speak to each
other.
In this mode an audio signal can always be sent via the SEND input to both interlocutors. The
audio signal that comes, for example, from the TELCO channel of the mixer, which sends all the
mixer console’s audio signals, WITHOUT what arrives from the telephone channel, i.e. the
RECEIVE. In this way an audio-loop with the telephone device is avoided.
