Set all pan controls and input equalizer (low, mid, and high) controls at the center detented positions. Also, center the slider type graphic equalizer controls. Set all other rotary type volume controls (Reverb/Effects, Auxiliary, Monitor, Input Gain, etc.) at their “0” positions (fully counterclockwise). All front panel switches should be in the “up” (not depressed) position. The slide switches on the graphic equalizers should be set to the position closest to you, marked “left” and “right” respectively. Turning It On. Some types of audio electronics produce a sharp “thump” when they are first turned on. This is called a “turn-on transient”. Some audio devices also produce a similar noise when they are turned off (a “turn-off transient”). While these transients are usually harmless, in some cases they can reach high levels and represent a danger to your loudspeakers. While we have designed your PX-2200 to have a very low turn-on and turn-off transient, other pieces of equipment that might be plugged into the PX-2200 might sound like a firecracker going off (or on), and the PX-2200, being the obedient servant it is, will just sit there and amplify that bang! To protect against such loudspeaker damage, it’s a good idea to turn on your entire system, without any program material playing. Always turn on all outboard equipment plugged into the PX-2200 first, and then turn on the PX-2200 last. When shutting off, go in the reverse order, by turning off your PX-2200 first, followed by all the other gear. Using The Peak LED. Choose any tape or CD from your collection and start your tape machine or CD player. Now, while watching the Peak LED, turn up the Trim control (clockwise) on the input channel you have the player plugged into, until the Peak LED begins to blink on and off regularly. Now turn the Trim control back down just a bit, so the Peak LED blinks only occasionally. That’s all there is to it! You have just optimized preamplifier gain for maximum headroom and minimum noise! Now repeat the process for all the other inputs you’re using. For microphones, talk or sing into the mic while you are adjusting the Trim control (or have a friend do the talking/singing). Talk or sing at approximately the same level you would expect in a performance (for a musical performance, this may be much higher than normal speaking voice). Once you have set the Trim controls on all channels, you should not have to reset them unless you plug something different into the input, or there’s a drastic change in input level (like a strong-voiced singer replacing a very weak-voiced singer). Using the Trim Control. Before an actual performance, you should perform a Trim control adjustment on each Input Channel. As you become familiar with your equipment, you should be able to judge the proper settings for the Trim controls from experience. If the same singer always uses the same microphone, for example, you’ll be able to set the Trim control in the same place each time (and probably just leave it there if you always use the same Input Channel).Watch the Peak LEDs. The Peak LED can help you determine the relative level of two different inputs (whichever input is loudest will light the Peak LED more often). However, if the Peak LED stays on for more than an instant, or if it lights frequently, you may be experiencing some “clipping distortion”, and you should probably readjust the Trim control downward slightly. 29 Phantom Power For Condenser Microphones. Before we move on from the inputs, the mic preamplifier, and the trim control, we should mention the phantom power feature of the PX-2200 series. An Explanation of Phantom Power. Your Fender PX-2200 Series Mixer provides phantom power (via the phantom power switch and internal circuitry) for powering condenser microphpones, if desired . Phantom power is the DC (direct current) power required for most condenser microphones (and some other items like active direct boxes) to operate. Although some electret condenser microphones also run on batteries, if they run out in the middle of a performance, you're sunk! By powering the microphone from the mixing console, you can be assured of uninterrupted operation. The reason it is called 1 phantom power, is due to the fact that the D.C. power for the microphone is “sneaked” down the same set of wires as the A.C. audio signal from the microphone, without affecting the sound or the performance of the mic. The +48 volt D.C. Phantom power is supplied to pins 2 and 3 of all balanced Lo-Z microphone input connectors, with pin 1 for ground (common), whenever the “Phantom” power switch is engaged. If any of your chosen microphones require phantom power, turn the phantom power switch “on"’ (depressed). The phantom power switch is located next to the red Fender Electronics logo in the upper right hand side of the mixer panel. When it is depressed, a red LED will light, showing that phantom power is on. Don’t worry, the phantom power supp...
