This is how to use two microphones in a large/split room where each side has it’s own amplifier w/ ceiling sensor. This will avoid each room broadcasting the other’s transmission.

WHEN USING THE IRT-60 SAPPHIRE PENDANT MICROPHONE IN EACH ROOM

Step 1: Designate one room for Channel A (room A), and one for Channel B (room B)

Step 2: In room B, change the channel on the IRT-60 Sapphire microphone from A to B. Watch this quick video to see how: https://www.youtube.com/watch?v=01TKGX1ByZo.

Note that the back cover is sometimes difficult to remove.

Step 3: On the opposite channel in each room, turn the mic channel gain all the way down.

  • Room A: On the TeachLogic amplifier/receiver, turn down the gain for Ch. B.
  • Room B: On the TeachLogic amplifier/receiver, turn down the gain for Ch. A.

WHEN USING THE IRH-35 HANDHELD MICROPHONE IN EACH ROOM

If using an IRH-35 handheld microphone, please note that it comes set on channel B. Therefore, you’ll need to change the other microphone to channel A (for room A).

Step 1: Unscrew the handle

Step 2: Remove the batteries and locate the channel selector.

Step 3: Change the mic for room A to channel A.

Advisory: If you are using both the IRT-60 and IRH-35 in each room, only one mic can be used at a time to avoid interference. Therefore if the handheld microphone is used, the Sapphire will need to be muted and vice versa.
