Heinrich's MC500C / MC500D Chairman & Delegate Unit Microphone adopts a high-quality sampling rate of 48KHZ, which is superior to CD sound quality, providing a clear and bright sound. The microphone also includes a built-in DSP audio processor, which eliminates low-frequency noise, and supports speech timing and timed speech functions. The delegate unit allows for speech application, which can be approved by the chairman. Additionally, the microphone includes an internal feedback suppression function and voice control function, which can be adjusted for sensitivity and can be turned on and off intelligently.

The microphone also has a 5-section EQ adjustment function, which can be used to adjust sound effects based on the speaker's voice characteristics for the perfect effect. The Chairman unit has a priority function, which allows for the turning off of all delegate units that are speaking. The microphone supports 100M network transmission, which enables hand in hand cascading and ensures that sound quality is not impacted by long-distance transmission.

The microphone supports voting, election, and rating functions, and the chairman unit can initiate voting and sign-in functions. Data statistics can be done without the need for a PC. Additionally, the microphone allows for the selection of language receiving channels, with the default being 15+1, but users can set it to 31+1 and 63+1. Finally, the microphone includes an LCD screen displaying voting information, sign-in information, delegate information, delegate status, and more.
