4.1.2
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.
4.1.3
Additional microphones 
(inputs 3 and 4)
Connect additional microphones to microphone/line 
inputs 3 and 4 as required. See figure 4.2. These 
microphones will mix with the background music.
Set the DIP switch settings for microphone/lines 3 and 
4, as required. See section 4.3.
