Secondary microphone (input 2)
Connect a secondary microphone to “microphone/line 
input 2”. See figure 4.5.
Microphone/line input 2 has a DIP switch (4) 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/100V input, Call station 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 next to the XLR connector 
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 4.5. These 
microphones will mix with the background music.
Set the DIP switch settings next to the XLR connector 
for microphone/lines 3 through 6, as required. See 
section 4.3.
