The packaging said (in part), "Dynamic Microphone for Active Musicians"
The sales/marketing department, usually ignorant of what they're
selling, wrote that drivel you're reading, which is intended simply to
sell more of whatever they're selling.
The CM500 has had an ELECTRET mic as far back as 2008, when W6XU,
another audio professional, arranged a group purchase for your Bay Area
contesting club. It DOES need Bias, which most modern rigs provide on
one pin of their mic connector. Simply adding a resistor of suitable
value (in the range of 5-10KOhms) between that pin and the mic input
pin, provides bias suitable for most electret mics.
