Resumen del manual
A parametric equalizer gives unrestricted control of all the notes your instrument can produce. The chart on page 20 shows the relationship between the notes you play and the corresponding frequency number. There should be very little guess work in deciding how you want to equalize your instrument once this chart is used. Most musicians are already familiar with the terminology A = 440 Hz. By learning the numbers of other notes, you take the guess work out of knowing where to set the controls on your parametric. A common problem with many instruments is uneven response from low to high notes. On string instruments you usually have one or more strings that are not as loud, when picked or bowed, as the other strings. On wind instruments; mouthpieces, reeds, and even weather changes can alter response. Most keyboard players really have response problems!! A general rule to follow is: listen carefully to your instrument and determine what the response problems are. Try first, to correct them with conventional means! Use equalization as a last resort, unless you are trying to achieve special effects. The less equalization you use, the easier it will be to get the "right" sound every time. Use the narrow and medium to wide band setup suggestions on pages 8 & 9 to get started. Patch your equalizer into your system after the pre-amplification stage. Most instrument pick-ups and direct outputs have too low a level to properly drive the input of the SC-63 or SC-66A. An effects loop will work well, or if you are feeding a mixer, use a direct in/out patch point on the channel. APPLICATION AND OPERATION FOR RECORDING The SC-63 and SC-66A can be used to augment or replace existing equalizers, and compensate for system inadequacies. Experimentation with the SC-63 and SC-66A will yield better results if the set up suggestions, trouble shooting information and reference graph information in this manual is read. ITEM: Critical Monitor Speaker Response Adjustment Most control room monitor speakers have fairly smooth frequency response. However, room acoustics can radically alter the freqency response you hear. By using an SC-63 or SC-66A patched in before the monitor speakers amplifier (or electronic crossover, if applies) you can compensate for room resonances or dead spots. For exact results, some type of realtime analyzer, or scope with a frequency sweep should be used. 1 1 ITEM: Individual Input Channel Equalization Most mixing consoles offer some type of equalization for each channel. Unless It is a full parametric type, it can not offer the complete flexability of the SC-63 or SC-66A. If your mixer does have a parametric type equalization section, the SC-63 or SC-66A will add more flexability with a minimum of ex pen se. Many mixers have individual channel direct in/out patch points that will interface with the SC-63 and SC-66A. If yours does not, a simple modification can usually be done by a qualified technician. Use the SC-63 or SC-66A to give instruments, playing in the same range, individuality. (ie; boost the fundamental frequencies of one instrument and the harmonics of the other) By becoming familiar with the chart on page 20, guess work will be minimized. Use the setup suggestions on pages 7 - 9 as a general guide. ITEM: Obtaining Better Results From Reverb And Effects Units By patching an SC-63 or SC-66A right before a reverb or effects unit, you can minimize high and low frequency loss. Boost those ranges before they go into a reverb or effects unit to compensate for losses. Isolating frequency ranges that go into an effects unit can also make an effect more pronounced. APPLICATION AND OPERATION FOR BROADCASTING ITEM: Announcer Voice Enhancement Only full parametric type equalization as offered by the SC-63 and SC-66A can modify voice frequencies accurately. Patch in an SC-63 or SC-66A after the voice microphone has been pre-amplified. Determine the frequency range of the announcers voice (100 Hz to 500 Hz fundamental, 800 Hz to 2,500 Hz presence area). Cut frequencies above and below, and boost fundamentals for warmth, or boost the presence area for definition. Experiment with bandwidth settings to match the exact range of the announcers voice. Sibilance problems (8,000 to 12,000 Hz range) can be notched out without affecting the overall sound. Use the step by step instructions on page 8 as a guide. ITEM: Record Wear Equalization Correction After several plays, a record loses its high frequency response. The SC-63 and SC-66A can be tuned to bring back some of that lost high frequency without altering frequencies that are still ok. Use the setup suggestions on page 9 as a guide. APPLICATION AND OPERATION FOR DISCOTHEQUES Graphic type equalizers, while initially easier to operate, can not offer the unrestricted tone control of the SC-63 and SC-66A. Old time radio effects, bass guitar emphasis, frequency selected voice over effects, and modified speaker response curve settings represent...
