With a frequency range of 470 - 865 MHz, it's ideal for venues with challenging RF environments. This combiner streamlines the operation of multiple personal monitoring systems by merging RF outputs from up to eight PSM transmitters into one single output. This results in a clean, reliable signal, enhancing reception quality and reducing issues like intermodulation distortion and multipath interference. Compatible with Shure's PSM300, PSM900, and PSM1000 wireless personal monitors, it's a must - have. It comes with advanced features such as a quieter fan that cuts down ambient noise and a smart temperature - sensitive fan power for better heat management. The intuitive LED indications for signal presence and overload make system monitoring a breeze. Whether you're handling large - scale events or complex audio installations, the PA821B meets all your RF networking needs with its reliable performance and advanced features.

Using the Shure PA821B is easy. First, connect the RF outputs from your Shure PSM300, PSM900, or PSM1000 transmitters to the corresponding inputs on the combiner. Then, connect the single output to your antenna set. When you power it on, check the LED indicators. Green lights on the 8 Input LEDs mean the signals are active. The other LEDs will show if there's signal presence or overload. As for maintenance, keep it in a clean and dry place. Since it has a temperature - sensitive fan, there's no need to worry too much about overheating. But if you notice the fan getting noisy, it might be time to clean it gently. And always use the provided power cable to ensure safe and proper operation. Remember, this combiner is designed for professional use, so handle it with care to keep it working well for a long time.
