What characterizes a non-preamplified communication assembly for the MK20?

A non-preamplified communication assembly for the MK20 is characterized by the permanently attached microphone amp connector. This design choice means that the assembly is simplified, avoiding the need for a preamplifier, which is often used in more complex communication systems to enhance the microphone's signal. Instead, a non-preamplified system relies on the inherent strength of the microphone signal and its direct integration with the other components of the diving system.

The permanently attached connector allows for a streamlined assembly process and can reduce potential points of failure, ensuring that divers have reliable communication without the additional complexities of external power requirements or extra connectors that might introduce noise or failure points. Overall, this direct connection promotes efficiency in setup and usage, making it well-suited for the specific communication needs within the MK20 system.
