[. . . ] DATA SHEET SEQ 30S & 30L STEREO GRAPHIC EQUALIZERS SEQ 30S SEQ 30L General Description Here's the long and the short of it. The SEQ 30S uses Short space-saving 20 mm sliders, while the SEQ 30L uses Long and more precise 45 mm sliders. [. . . ] An Input Level control is provided along with a Bypass switch, enabling easy gain comparisons between equalized and unequalized signal. +4 dBu and Overload indicators detect both input and post-EQ levels. Either unit interfaces easily to many types of systems. Use the balanced XLR Inputs and Outputs, or the balanced ¼" TRS Inputs and unbalanced ¼" TS Outputs.

Truth in slider position became a requirement. The curve traced out by the slider positions on constant-Q designs indeed represents the actual changes to the frequency response. You use a constant-Q graphic the same way you use a conventional graphic. You just get the desired results quicker, with far less after adjustment to the adjacent sliders. Eliminating a phenomena Rane calls "equalizing the equalizer". The accompanying figures dramatically show the advantages of constant-Q designs.

" Data Sheet-3 SEQ 30S & 30L STEREO GRAPHIC EQUALIZERS SEQ 30S Rear Panel SEQ 30L Rear Panel Architectural Specifications The graphic equalizer shall be of constant-Q design to minimize interactions between adjacent bands, and contain frequency bands located on standard ISO center frequencies. Each band shall have a bandwidth of 1/3-octave with a boost/ cut range of 12 dB. A detented and positively grounded 0 dB point shall be provided on 20 mm (SEQ 30S) or 45 mm (SEQ 30L) linear sliders with dust dams. A single set of sliders shall control both channels. [. . . ] The unit shall be a Rane Corporation SEQ 30S or SEQ 30L Stereo Graphic Equalizer. ©Rane Corporation 10802 47th Ave. W. , Mukilteo WA 98275-5098 TEL (425)355-6000 FAX (425)347-7757 WEB http://www. rane. com Data Sheet-4 All features & specifications subject to change without notice.
