REMOTE MUTE CONTROL + AUX
OUTPUTS connector
The Mic Mute and Buzzer Mute push buttons on
the PS 680 allow for sending these mute signals
to all channels simultaneously.
In case it is required that these mute signals can
also be sent to each channel separately, an
external switch box is needed, to be connected to
this D25 connector.
To activate a mic of buzzer mute, the switch box
connects the referring pins of the D-25 connector
to ground. See D-25 pin layout.
The external switch box is made to order. Specific
requirements of the user as far as for instance
type of switches can be fulfilled.
On pin 2 and 3 of the D-25 connector are the
unbalanced AUX signals. It concerns the pre-
amplified signals taken after the AUX master
volume controls (#6) before they are sent to the
Aux matrix. Use high impedance loads only
(minimum 20 kΩ); lower loads may disrupt the
AUX signals to the intercom lines.
