Power Cord Protection -- Power supply cords should be routed so that they are not likely to be walked upon or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit the MicroSeries 1202. Object and Liquid Entry -- Care should be taken so that objects do not fall into and liquids are not spilled into the inside of the MicroSeries 1202. [. . . ] Cutting slightly at this frequency can do wonders for muddy tracks and boomy room acoustics; cutting more drastically can help fix poppy microphones. This control gives you up to 15dB boost or cut at 12kHz, and is also flat at the detent. Use it to add sizzle to cymbals, and an overall sense of transparency, or edge to keyboards, vocals and guitar. Turn it down a little to reduce sibilance, or to fix hiss on a tape track. We've designed a full 15dB of boost and cut into each equalizer circuit, because we know professionals occasionally need that range. But if you max the EQ's on every input you'll get mix mush. If you're using the MS 1202 for recording, equalize subtly and use the left sides of the knobs (cut), as well as the right (boost). 8 MS1202 MODIFICATION: Convert AUX SEND 2 to pre-EQ/pre-fader Channels 1­4 only. You will be working on the solder side (bottom) of the circuit board. (2) Locate this area on the circuit board. Near the Aux Send 2 pots, channels 1 thru 4. (3) Cut trace here. phone amp" chip, we use a high-current version of our main output amplifier, which is why it can really clean out your cochlea if you crank it up too far. . . but still be a very clean signal source. 21 22 Metering The MS 1202's 3-way peak metering system is made up of two columns of twelve LED's (21) and an INPUT CH. Thanks to the MS 1202's wide dynamic range, you can get a good mix with peaks flashing anywhere between ­30 and +10dB on this display. Most PA amps clip at +4, and most recorders aren't so forgiving either. For best real-world results, try to keep your peaks below +7. i/METERING button, the display can be used to monitor three different sources: · Stereo Output. This is the normal function you'd expect from any mixer. But don't go away, there's more!METERING button IN and you get input metering as well. The right column of LED's displays the overall operating level of all 12 channels and AUX Returns (preMaster Gain). To CLIP +22 monitor just one +10 channel, turn down +7 the others. The left +2 column of LED's 0dBu 0 CAL displays the -2 combined operat-4 ing levels of -7 Channel 1­4's mic -10 preamps. [. . . ] We won't need these to repair the mixer (unless you have interharmonic under-slewing bipolar crosstalk in your rack ears, a rare but particularly nasty problem). Pack the mixer in its original shipping carton with the foam end caps in place. If you do not have the carton, just ask for one when you get your RA number and we'll ship it to you promptly, C. O. D.
