Variable Impedance Control Variable impedance control - Vari-Z - to shape and contour the sound of your ribbon or dynamic microphone. Variable High-Pass Filtering Continuously variable high-pass filtering @ -6dB per octave works in tandem with the variable impedance control for even greater tonal shaping. Variable Gain Two gain settings - more & max - yield up to +25dB of ultra-clean gain for low output dynamic & ribbon microphones.
