4. Setup Guide

4.1 Connecting the Transmitter

1. Identify the M1 Transmitter (labeled "M1 TRANSMITTER").
2. Plug the XLR male end of the transmitter directly into the XLR output of your dynamic or condenser microphone.
3. If using a condenser microphone, ensure the 48V phantom power is activated on the transmitter (refer to Section 5.3).

4.2 Connecting the Receiver

1. Identify the M1 Receiver (labeled "M1 RECEIVER").
2. Plug the XLR female end of the receiver into the XLR input of your audio mixer, PA system, amplifier, or other audio receiving device.
3. If your receiving device uses 1/4" or 1/8" inputs, use the provided XLR to 1/4" and 1/4" to 1/8" adapters as needed.
