The F603B is a high performance Low-Q four band equalizer for tracking and mixing (Q = 0.8). The F603B features passive LC (Inductor/Capacitor) filters combined with a very short signal pass. The low and high frequency filters are shelving types, while the mid frequencies are band pass filters. Each shelving filter has four different frequencies while the band pass filters offer six. The active filter range is indicated by LEDs. To facilitate sound comparisons, a true “hard†bypass is available. The gain range for each filter is +/- 16 dB. All filters are switched by relays to guaranty the highest possible sound quality. The F603B exhibits unrivaled silkiness, but at the same time an extremely detailed sound stage. The high power output stage with an impedance of less than 20 Ohms and a driving capability of up to +/- 200mA ensures no loss of performance with even the most demanding complex loads.
