Secondary microphone (input 2)

Connect a secondary microphone to "microphone/line
input 2". See figure 4.2.
Microphone/line input 2 has a DIP switch (11) at the
rear of the unit for setting the VOX mode. If the DIP
switch is set to VOX, the microphone/line input will
automatically be switched when a signal is sensed at the
microphone/line 2 input. For example, when someone
speaks into the microphone, other sound will either be
muted or ducked, depending on the setting of the
ducking level control at the rear of the unit. See
section 4.3.
The Tel. emergency/70V input and Microphone/line
input 1 all have priority over the Microphone/line
input 2. Therefore, any signal received on any one of
these inputs will always be heard regardless of the
ducking level control setting for Microphone/line
input 2.
Set the DIP switch settings for microphone/line input 2
as required. See section 4.3.
