DIP Switch Settings
Use the DIP switches to configure logic settings and mute button behavior. DIP switches are down by default, and settings can
only be changed when the device is powered off. Changes take effect when the mute button is powered back on.
DOWN (default) UP
1 Toggle Momentary
2 Push-to-Mute Push-to-Talk
3 Local Mute Logic Control
4 Green LED = talk, Red LED = mute
Red LED = talk, Green
LED = mute
5 and 6 work together to make 4 touch
sensitivity settings: 1 (lowest) - 4 (highest)
5 UP, 6 DOWN = 1
5 DOWN, 6 DOWN = 2 (default)
5 DOWN, 6 UP = 3
5 UP, 6 UP = 4
Note: Higher sensitivity settings are more likely to cause accidental touch responses.
Connecting to a Logic-Enabled Device
Use these settings if connecting the microphone to a logic-enabled device, such as the ANI4IN-BLOCK or ANI22-BLOCK:
Connect the A400MB LED (input) to the ANI LED (output) to illuminate the microphone LED when the logic signal
changes. *
Connect the A400MB switch (output) to the ANI switch (input) to send a logic signal from the A400MB to the ANI. *
Set DIP switch 3 to up. This disables local muting. Pressing the A400MB sends a logic signal (the microphone passes
audio regardless of whether the button is pressed or not).
Set DIP switches 1 and 2 to configure how the A400MB sends SWITCH OUT logic.
