4.1.2Secondary microphone (input 2)
Connect a secondary microphone to “microphone/line input 2”. See figure 4.4.
Microphone/line input 2 has a DIP switch (12) 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 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.
4.1.3Additional microphones (inputs 3 and 4)
Connect additional microphones to microphone/line inputs 3 and 5 as required. See figure 4.4. These microphones will mix with the background music.
Set the DIP switch settings next to the XLR connector for microphone/lines 3 and 4, as required. See section 4.3.
