Transmitter size and fit** The Beltpack Module transmitter cavity dimensions are  87 x 68 x 27 mm / 3.4 × 2.7 × 1.06 in. Your transmitter should fit comfortably within these measures. **Additionally take into account: ** - Antenna length - Transmitters with non-bendable antennas may not fit.  - Connector size - Large connectors could make installation difficult.  - Overall shape - Tall transmitters with long antennas or bulky connectors may not fit properly within the cavity and cover. #### **2. Adapter cable connectivity:** The Beltpack Module set includes two adapter cables:  - Shure (3.5 mm to 4-pin mini XLR)  - Sennheiser (3.5 mm to 3.5 mm) Other adapter cables are available in[our online store](https://catchbox.com/accessories) or from third-party audio equipment retailers. In some cases, our R&D team may be able to create a custom adapter cable for certain compatible beltpack transmitters. **How to check compatibility ** To confirm whether your beltpack transmitter works with the Beltpack Module, check our C[ompatibility list](https://catchbox.com/compatibility-list/beltpack-module).
