442 EQ DUAL CHANNEL 15 BAND 2/3 OCTAVE GRAPHIC EQUALIZER 452 EQ SINGLE CHANNEL 31 BAND 1/3 OCTAVE GRAPHIC EQUALIZER USER’S GUIDE.
2 EQUALIZER OVERVIEW – FEATUR ES AND GENERAL INFORMATION: MODEL 442 TWO CHANNEL 15 BAND 2/3 OC TAVE PRECISION GRAPHIC EQUALIZER The Model 442 features constant Q circuitry with a 3% center frequ ency accuracy.
3 Balanced output requires using Pin 2 of the XLR or the tip of the 1/ 4” TRS as output Hi (+) and using pin 3 of the XLR or the ring of t he 1/4” TRS as Lo (-). It does no t require pin 1 or signal ground. The signal exists differentially between the two balanc ed leads.
4 Here are some tips to help you with the initial set up: 1. Set channel levels to the center detent 0dB on the front panel. 2. Bypass the equalizer (Note: Select the bypass switch and press - the red LED is on.) 3. Set the frequency slide contro ls to the center detent or 0dB.
5 2. FILTER LEVEL CONTROLS Each of these sliders controls t he output level of each of the 31 (o r 15) bandpass filters. The center detent position is grounded to assure flat response. 3. FILTER RANGE SWITCH & INDICATORS The gain range of the filter sliders is switchable (as a group) from +/- 6dB to + /-12dB for maximum boost/cut capability.
6 8. LEVEL CONTROL This controls the level of signal coming into t he equalizer. Turn this cont rol down if the Clip LED illuminates steadily (meaning too st rong an input signal). Unity gain can be set by turning this knob to its center detent position.
7 nel. CAUTION: After checki ng the AC supply voltage, be sure that the correct fuse is in the fuse holder; 0.6Amp for 100-103V AC, as well for 220-240VAC.
8 FOR UNBALANCED CONNECTIONS Use 1/4 inch tip-ring-sleeve or mono phone plug c onnectors or RCA phone jack connectors wired as follows: Phone Jack : Connection : tip = high ring = no connection sleeve = ground APPLICATIONS Graphic equalizers may be used wherever modification of the frequency contour of a sound system is needed.
