GROUNDING OR POLARIZATION
• If this product is equipped with a polarized alternating current line plug (a plug having one blade wider than the other), it will fit into the outlet only one way. This is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug should still fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polarized plug.
• If thi s produ ct is equip ped wit h a thr ee-wire grounding type plug, a plug having a third (grounding) pin, it will only fit into a grounding type power outlet. This is a safety feature. If you are unable to insert the plug into the outlet, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the grounding type plug.
POWER-CORD PROTECTION - Power-supply cords
should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the product.
OUTDOOR ANTENNA GROUNDING — If an outside
antenna or cable system is connected to the product, be sure the antenna or cable system is grounded so as to provide some protection against voltage surges and built-up static charges. Article 810 of the National Electrical Code, ANSI/NFPA 70, provides information with regard to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna-discharge unit, co nn ec ti on to gr ou nd in g ele ct ro de s, an d requirements for the grounding electrode. See Figure A.
LIGHTNING — For added protection for this product
during a lightning storm, or when it is left unattended and unused for long periods of time, unplug it from the wall outlet and disconnect the antenna or cable system. This will prevent damage to the product due to lightning and power-line surges.
POWER LINES — An outside antenna system should
not be located in the vicinity of overhead power lines or other electric light or power circuits, or where it can fall into such power lines or circuits. When installing an outside antenna system, extreme care should be taken to keep from touching such power lines or circuits as contact with them might be fatal.
OVERLO ADING — Do not overload wall outlet s,
extension cords, or integral convenience receptacles as this can result in a risk of fire or electric shock.

QUICK START
American Audio would like to thank you for your purchase of this great product. For those of you that are to impatient to read the entire user manual we have compiled these quick start instructions. We hope that you will at least read through these instructions to familiarize yourself with the basic under­standing of the unit. The Q-2422/SX is part of American DJ’s continuing evolution in audio technol­ogy. This unit has been built and designed with the typical DJ in mind, by DJ’s. We have attempted to provide you with the most reliable product on the market by only using components made from quality products.
MASTER LEVEL - Use this level control to set your volume output. Try never to send an output of more than +4dB to your system. A signal at levels higher than this will start to distort and may cause damage to your system and speakers. Remember that a distorted signal from your mixer will only be multiplied throughout your system.
CHANNEL TRIM LEVEL - The channel trim levels are not to be used as volume controls, never use the channel trim to set the output volume. These controls are used to aid in distortion control. Use this control to preset your signal level before the crossfader. With your channel fades in the maximum position, use the channel trim level to set an average output level of about +4dB on you master level meter.
HEADPHONES - To avoid sever hearing damage always be sure the headphone level is set to mini­mum before plugging them in. Never put the headphones on without making sure the headphone level is turned down.
MAIN MIC - The main mic connector uses a Nuetrik combo plug which allows you to connect either a 1/4” unbalanced jack or by a standard 3-pin XLR balanced connector. The main mic also has an independent volume control with separate high and low level adjustments. If feedback occurs when using the mic, try lowering the “low” frequency level, this may reduce feedback. Always leave the mic level to it’s minimum level when not in use.
PHONO/AUX/LINE SWITCH (5) - This switch is used to change the selected input from phono to line and vice versa. Channels 1 and 2 may be switched PHONO/AUX or LINE. Channel 3 may be switched LINE 3 or LINE 4. The selectors for AUX1/PHONO1 and AUX2/PHONO2 are on the rear panel (36).
