1. The Electret Condenser Capsule
Unlike dynamic mics, the MD-100 uses an electret capsule that requires a low-current DC bias voltage (typically 1.5V to 9V). The capsule itself converts acoustic pressure to a high-impedance, millivolt-level audio signal. repeater-builder
: The microphone base features a "High Emphasis" and "Low Cut" filter system. The High Emphasis filter (often labeled as Filter On/Off Yaesu Md 100 Schematic
) uses an internal op-amp circuit (typically a PC4572C or similar) to boost higher frequencies for better punch in DX or noisy conditions. Thru/Filter Switch
