Brooks KS-55 Active Crossover

Uses active devices (transistors, IC's, tubes) and some form of power supply to operate.

Condenser Mic (Capacitor Mic)
A microphone that uses the varying capacitance between two plates with a voltage applied across them to convert sound to electrical pulses. Condenser microphones need a power supply to provide the voltage across the plates, which may be provided by a battery within the case of the microphone, or it may be provided from an external phantom power supply. A condenser mic is more sensitive and has a faster reaction to percussive sounds than a Dynamic mic and produces a more even response. See Electret Mic.
