W2377 filter functions
• Level potentiometer with midway indent at 0dB
• Frequency potentiometer for low, mid and high band filter
• 9 stepped ELMA switch for the adjustment of the filter resonance (Q-factor)
• Frequency selective high-pass and low-pass filter function
• Illuminated switches for the true bypass and solo function
• Illuminated button (Focus) activates the invert-function of the level control
The three fully parametric RS Audio Technique W2377 filter modules covers the complete frequency range from 20 Hz to 23 kHz. The level potentiometer allow continuous gain settings with an effective range of +/-10dB. Furthermore the midway indent at 0dB facilitates the mechanical handling.
The setting of the overlapping frequency bands (low, mid, high) with just three different modules allows a precise control of each band and offers the possibility to combine the modules at will. The filter resonance can be set in steps from 0,3 to 10 and the via left stop
position respectively the right stop position a high-pass or low-pass filter can be activated. The frequency control adjust the limiting frequency of these filters.
Via the illuminated switches and buttons a quick change between processed and unprocessed material is possible at any time. An Off switch activates the true bypass function, which removes the unit from the signal chain without undesired effects. In a network of more than one W2377 the Solo switch bypasses all operating units, so that only the chosen modul is active. The Focus button inverts the level of a module so that a quick selection of the frequency components, that has to be manipulated is easy.
The units are aligned with the api® 500 series and can be integrated in any api® environment. High-quality ALPS® potentiometers and step switches from ELMA® ensure a long-term usage of the units in continuous operation. For the alignment of different studio environments the level matching of the in- and outputs can be adjusted with a variable resistor on the printboard.
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
