4.1.3 Secondary microphone (input 2)
Connect a secondary microphone to “microphone/line
input 2”. See figure 4.3.
Microphone/line input 2 has a DIP switch (3) 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, Call station input, and
Microphone/line input 1 with trigger 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.
4.1.4 Additional microphones
(inputs 3 through 6)
Connect additional microphones to microphone/line
inputs 3 through 6, as required. See figure 4.3. These
microphones will mix with the background music.
Set the DIP switch settings for microphone/lines 3
through 6, as required. See section 4.3.
