I’d like a 2nd mic and body pack to connect to this. Do I need to buy two of these systems, or will another body pack and mic
The Shure BLX4 Tabletop Wireless Receiver included with the Shure BLX4 Wireless Microphone System with SM31FH Cardioid Fitness Headset Kit (H9: 512 to 542 MHz) is a single channel receiver, so it will only work with one transmitter at a time. In order to use two transmitters at the same time, you will either need two of the BLX4 receivers or the Shure BLX88 Dual-Channel Tabletop Wireless Receiver - H9: 512 to 542 MHz (B&H # SHBLX88H9), which will work with two transmitters simultaneously.
