The R102 series is an active aluminum ribbon microphone designed for the recording studio. It features the high sensitivity of a condenser microphone, yet exhibits the smoother frequency response and excellent transient response of a ribbon microphone. The speed response of a ribbon mic is optimal among all types of microphones. There two models from R102 series, one is R102 with black grille and the other is R102 MKII with golden grille R102 is classical standard ribbon microphone R102MKII is a ribbon microphone with extended high frequency to studio condenser grade, but keep the same excellent transient response of ribbon microphone. Classical ribbon microphones will exhibit a roll off in high-frequency response, but R102MKII is a breakthrough ribbon microphone can maintain high frequency response up to 18 kHz.
