Brooks Cinema XR 607 Hi-Z

An abbreviation of the term High Impedance (Impedance of 5000 or more ohms).

Electret Condenser
A condenser microphone that has a permanently polarized (charged) variable capacitor as its sound pressure level sensor.

Brooks Cinema KP 30 Dynamic Mic
Robust type of microphone which picks up the sound on a diaphragm connected to a coil of wire which moves within a magnet. An alternating current is induced into the wire which provides the electrical output. Most dynamic mics have low output impedance of 200 Ohms. See Condenser Mic.
