Roger Schult - W2377 MK2 - selectable frequency ranges
W2377 MK2 filter functions
- Fully parametric, analogue filter covering the entire frequency range from 20 Hz to 23.3 kHz
- Three switchable overlapping frequency ranges: 20 Hz to 233 Hz, 200 Hz to 2330 Hz, 2 kHz to 23.3 kHz
- High precision frequency selection via rotary control
- Adjustable Q-factor (0.3 to 10) via high-grade ELMA switch
- Filter gain range of -10 dB to +10 dB via continuously variable potentiometer
- User-selectable high- and lowpass functionality across the entire frequency range
- Illuminated true bypass switch
The W2377 MK2 filter was conceived and designed for recording and mixing studios, satisfying the demand for covering the entire audio spectrum with a single filter unit. This universal filter concept allows using the W2377 MK2 as a subtle program equalizer, and/or as creative tool for radical EQ and tone shaping alike.
The W2377 MK2's fully parametric filter with three selectable frequency ranges covers the entire audio spectrum from 20 Hz to 23.3 kHz. Usefully, the overlapping frequency ranges are split into three decades that can be selected via a three-position switch to provide precise access to the entire frequency range of the unit. A high-grade, selected potentiometer adjusts the operating frequency while the Q-factor of the bell filter may be set between 10 and 0.3 via a rotary switch. As an additional feature, the Q-factor control includes a selectable high or low pass with a slope of 12 dB/octave at the left and right limits of the switch.
A backlit "on" pushbutton relay switch enables or disables the filter without switching noises in the signal chain. Conveniently, the brightness of the backlight can be adjusted using jumpers on the unit's electronics board.
As all Roger Schult products, the W2377 is hand-crafted and precision-engineered in Germany.
Applications
First-class fully parametric filter module for api® 500 systems for frequency correction during recording, mixing and mastering as well as effect filter for delimitation of the band and accordingly the elimination of interference frequencies
