B. Greater gain-before-feedback characteristics can be achieved by turning up the sound system to the feedback point and attenuating the oscillating (ringing) frequency. 1/3rd octave resolution is best for this application. Turn the system up to feedback again and attenuate the second oscillating frequency. Repeat the process again for the third oscillating frequency. C. Protection of amplifiers and speakers can be accomplished using the LOW CUT feature of the equalizer. Wind noise or sub sonic frequencies can cause damage to the amps and/or speakers. However, by rolling off the extreme low frequencies, a measure of protection is added to the system without severely affecting the overall sound quality. D. In noisy environments, the audio signal can be tailored for better intelligibility and penetration. This is particularly useful for paging systems. E. Creative use of the equalizer allows shaping of the signal for a more pleasing sound or for special effects. The only limits are those of taste and imagination. 5 6SR Series MUSICAL INSTRUMENT APPLICATIONS A. Putting an equalizer in line with a musical instrument allows you to modify the sound of the instrument. You can brighten the sound, add body to a thin sounding instrument, or you can give the sound a totally different character. B. An equalizer allows you to eliminate unwanted sounds, such as the 60 cycle hum from a badly grounded sound source. STUDIO APPLICATIONS A graphic equalizer is one of the most useful tools in the sound engineer's DOD equalizers offer the features and the flexibility to deliver uncompromising quality in the studio. A. Fix a track that doesn't sound quite right. Put the equalizer in a channel insert. B. Create an artificial stereo image by splitting a monaural signal and equalizing the split signals differently. Pan one signal to the right and the equalized signal to the left. C. Shape the sound by changing the frequency response of the track. D. Special effects like telephone sounds are done by cutting off the low end at 200 Hz and the high end at 6 kHz. Also, when used with other pieces of equipment, you can do some real signal processing magic. Emphasizing the high frequencies of a signal and feeding the modified signal to the side chain of a compressor creates a de-essing effect. By emphasizing the low frequencies and feeding the signal to the side chain creates a de-thumper. You can also reduce unwanted frequency-dependent noise in a signal by cutting the offending frequencies with an equalizer and letting a noise gate "key" on the modified signal while letting the original signal pass, gating the unwanted sounds. SR Series 7 OPERATION FRONT PANEL FUNCTIONS DESCRIPTION POWER SWITCH: Turns the power to the equalizer on or off. EQUALIZER SLIDERS: Each one of these linear potentiometers will boost or cut its noted frequency by +/- 12 dB. When all the sliders are in the center detented position, the output of the equalizer is said to be flat. The numbers marked over the top of each slider represent the center frequency that each band will control. INPUT LEVEL CONTROL: This control sets the signal level to the equalizer. It is capable of +/- 12 dB of gain. The level is indicated on the INPUT LEVEL BAR GRAPH. This control is used to compensate for variations in volume due to gain changes caused by equalizing individual frequencies. LOW CUT FILTER SWITCH: This switch electronically inserts a filter into the signal path, which cuts the low frequencies at 12 dB per octave (-3dB @50 Hz). The LED indicator lights when the switch is depressed and the filter is in the circuit. IN/OUT BYPASS SWITCH: This switch inserts or removes the equalizer channel from the signal path. An LED indicator lights when the switch is depressed and the equalizer channel is in the circuit path. The bypass function is FET switched to prevent switching transients when inserting the equalizer into the circuit. LED LEVEL INDICATOR: The LED level indicator shows the signal level to the unit. REAR PANEL FUNCTIONS BALANCED INPUT: Accepts a standard XLR type connector [see section on installation for wiring connections]. The 1/4” phono jack may also be used for balanced inputs when used with a TRS connector. Maximum allowable input level is +18 dBu. Input impedance for a balanced connection is 80 kOhms. UNBALANCED INPUT: Accepts an1/4” plug (see section on installation for wiring connections). Connections are unbalanced. Maximum allowable input is +18 dBu. Input impedance for the unbalanced connection is 40 . . BALANCED OUTPUT: Accepts a standard XLR type connector [see section on installation for wiring connections]. A 1/4" TRS ...
