QUICK START INSTRUCTIONS

• QUICK START: American Audio® would like to thank you for your purchase of this great audio prod-uct. For those of you that don’t have the time 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 basics of this mixer. The Q-2422 PRO is part of American Audio’s continuing evolu-tion in audio technology. This unit has been built and designed to meet the needs of a typical DJ. We have attempted to provide you with the most reliable product on the market by using only components constructed of the finest material.
• MASTER LEVEL – Use this level to control your main volume output. Try never to send an output of more than +4dB to your system. 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 you mixer will only be multiplied throughout your system.
• CHANNEL GAIN LEVEL – The channel gain 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 these control to preset your signal level before the crossfader. With your channel faders in the maxi-mum position, use the channel trim level to set an average output level of about +4dB on your master level meter.
• HEADPHONES – To avoid damaging your headphones always be sure the headphone volume level (16) is set to minimum before plugging them in. To avoid sever hearing damage, never put the head-phone on without making sure the headphone level is turned down.
• MAIN MIC – The main mic connector uses a combo plug that 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 indepen-dent volume control.
• When feedback occurs when using the mic, try lowering the level this may reduce the feedback. Always leave the mic level to it’s minimum level when not in use.
• Note: We recommend that you use a 500-600ohm microphone for the best sound quality.
• PHONO/AUX LINE LEVEL SELECTOR SWITCH – This switch is used to change the selected input from phono to line and vice versa.
• The switch selectors are on the rear panel.

Turning the knob in a counter-clockwise direction will decrease the amount of bass applied to the ZONE signal, turning the knob in a clockwise direction will increase the amount of bass applied to the ZONE signal.
    • ZONE LEVEL VOLUME OUTPUT CONTROL – This rotary knob is used to control the zone level volume. The zone level is not PFL, it is essentially a second master output volume with separate output volume control.

19. HEADPHONE JACK – This jack is used to connect your headphones to the mixer allowing you to monitor the cue source. Use headphones only rated at 8 ohms to 32 ohms. Most DJ headphones are rated at 16 ohm, these are highly recommended. Always be sure the CUE LEVEL VOLUME (16) is set to minimum before you put the headphones on.

20. SPLIT CUE – This button will activate the “Split Cue” function. When used with a set of stereo headphones, the Split Cue function will assign the Cue signal to the left channel of the headphones and the Program (main output) signal to the right channel of the headphones. Essentially splitting the cue signal in half. This process will allow for headphones mixing. The CUE MIXING CONTROL (18) will also work in conjunction with function. Please note that this function will only work with a set of stereo headphones.

21. CUE LEVEL VOLUME CONTROL – This knob is used to adjusts the headphone volume output level. Turn the knob in a clockwise direction to increase the headphone volume.

22. MASTER VOLUME CONTROL – This slider is used to control the master output level (main volume). To avoid distorted output try to maintain an average output signal level no greater than +4 dB. To avoid speaker damage that may be caused by excessive volume, be sure this slider is always set to zero (completely down) before turning the unit on.

23. CUE MIXING CONTROL – This functions allows you to monitor the Cue level as well as the Program (main output) level in your headphones. A channels Cue Level may only be monitored if the channels CUE (19) function is selected. To select a channels cue function press the CUE BUTTON (19) that is directly associated with the specific channel you wish to monitor. You may use the mixing function to blend both the Cue level and the Program level together. You can vary the output level to either hear more or less of either of the two levels. Sliding the Cue Mixing fader to the CUE posi-tion (left) will allow you to hear more of the Cue level. Sliding the knob to the PGM position (right) will allow you to hear more of the Program level (main output). You may also use the Cue Mixing Control to hear either the Cue level or the Program level exclusively. If the fader is in the full CUE position you will only hear the cue level, if the fader is in the full PGM position you will only hear the main output. This function is especially useful when mixing without an monitor.

24. CUE BUTTON – These buttons are used to activate a channels “CUE” mode. The red CUE LED will glow when a channels cue mode is activated. The Cue function sends a channels incoming signal to the headphones. The cue level is adjusted by the CUE LEVEL KNOB (16). Be sure the CUE MIXING SLIDER (18) is set to the “CUE” position to hear a selected channel source.

25. Q-START ON/OFF BUTTON – This function works in conjunction with a compatible American DJ® or American Audio® “Q” Start CD player. When used with a compatible CD player, you can use the crossfader to start and stop a CD Player with the slide of the mixer’s CROSSFADER (22). The ON/OFF “Q” START BUTTTON activates the FADER “Q” START feature. When in the ON position (GREEN LED WILL BE LIT), the FADER “Q” START automatically returns the CD player to the preset CUE POINT.

    • For example; Assuming you have two compatible American Audio™ CD players or a compatible dual CD player connected to channels one and two. When the Fader “Q” Start option is turned on, sliding the crossfader to the far left position will trigger playback on CD player 1. When the crossfader is pushed to the far right position, playback on CD player 2 will begin, and CD player 1 will return to the cue position. Refer to your American Audio CD player user manual for setting CUE POINTS. Turn the
    • ON/OFF BUTTON to the OFF position (RED LED IS NOT LIT) to disengaged “Q” Start function and resume to a normal fader.

26. FADER ASSIGN SWITCH – This is a four position switch that assigns a channel to the CROSS-FADER (22). When a channel is assigned to the left side of the CROSSFADER (22) that channels output level is routed to and controlled by the CROSSFADER  (22). Sliding the CROSSFADER (22) to left position will send the volume output of the assigned channel to the MASTER VOLUME LEVEL (17), siding the CROSSFADER (22) to right position will cut that channels volume to MASTER VOLUME LEVEL (17). The reverse is true for the right channel fader assign switch. When the assign switch is set to the “OFF” position the crossfader will have no function.

27. FEATHER FADER PLUS CROSSFADER – This fader is used to blend the output signals of chan-nels one and two together. When the fader is in the full left position (channel 1), the output signal of channel one will be controlled by the master volume level. The same fundamentals will apply for chan-nel two. Sliding the fader from one position to another will vary the output signals of channels one and two respectively. When the crossfader is set in the center position, the output signals of both the channels one and channels two will be even.

28. CHANNEL VOLUME FADER – These faders are used to control the output signal of any source assigned to its particular channel. However, master volume is controlled by the MASTER VOLUME CONTROL (17).

TYPICAL MIXER SET-UP

Typical Balanced Output Set-up

• This image details a typical stereo output layout.
• Note the use of the Balanced XLR Jacks on both the mixer and the amplifier.
• Always use the balanced output jacks whenever possible.
• The balanced output jacks should always be used for cable runs in excess of 15 feet.
• Using the balanced jacks will ensure a clean signal through out the entire audio system.

CLEANING

Due to fog residue, smoke, and dust, cleaning the mixer should be carried out periodically to residue build up.

1. Use normal glass cleaner and a soft cloth to wipe down the outside casing.
2. Use a cleaner specially designed for electronics to spray in and around the knobs and switch. This will reduce small particle built up that can effect the proper operation of the mixer.
3. Cleaning should be carried out every 30-60 days to prevent heavy built up.
4. Always be sure to dry all parts completely before plugging the mixer in.

Cleaning frequency depends on the environment in which the mixer operates (i.e. smoke, fog residue, dust, dew).

CROSSFADER REPLACEMENT

The crossfader is “Hot Swapable” which means it may be replaced at any time, even when power is applied. Only replace with American Audio Part Feather Fader Plus. Replacing with any other model fader may seriously damage your mixer.

Replacing the Crossfader:

1. Disconnect the mixers main power supply
2. Using a number two Phillips screw driver, unscrew the each of the stainless steel retain screws that hold the crossfader in place.
3. Gently remove the crossfader from its seated position. You may need to wiggle the crossfader slightly to remove it.
4. After removing the crossfader, disconnect the ribbon cables that attach the crossfader to the PC board. Grasp the crossfader by its base and pull each of the ribbon cables by its connector not the actual cables.
   • The connector is designed to only fit one way, so don’t worry about the connectors orientation.
5. Connect the new crossfader to the ribbon cable and replace in reverse order.
