QUICK START: American Audio® would like to thank you for your purchase of this great audio prod- uct. For those of you that are too 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 basics of this mixer. The Q-FX19™ is part of American Audio’s continuing evolution 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 con - structed 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 you master level meter. HEADPHONES - To avoid damaging your headphones always be sure the headphone volume level (15) 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.

1. MICROPHONE 1 - This combo jack will accept a standard 1/4 plug or XLR 3-pin balanced male
plug. The volume output level for this microphone will be controlled by its own respective
CHANNEL
KNOB
(27). Note: We recommend that you use a 500-600ohm microphone for the best sound
quality.
2 . CHANNEL GAIN CONTROL - This adjustment is used to adjust the audio source signal input gain
for a channel. Never use the gain control to adjust a channels output volume. Setting the gain level
properly will ensure a clean output signal. An improper gain level adjustment will send a distorted
signal throughout the entire audio line which may damage speakers and amplifiers. To properly set a
channels gain level control:
1. Be sure the MASTER VOLUME CONTROL (
18) is set to level 8.
2. Set the CHANNEL FADER (
23) to level 8.
3. Begin playback on an audio source connected to the channel you are adjusting.
4. Use the Gain Control to adjust an average output volume of +4 dB
.
5. Repeat this step for all channels
3.
CHANNEL TREBLE CONTROL - This knob is used to adjust the treble levels of a channel
allowing for a maximum treble gain of 1
2 dB or maximum decrease of -30dB. Turning the knob in
a counter-clockwise direction will decrease the amount of treble applied to a channel signal,
turn-
ing the knob in a clockwise direction
will increase the amount of treble applied to a channel signal.

allowing for a maximum midrange gain of 12dB or maximum decrease of -30dB. Turning the knob in a counter-clockwise direction will decrease the amount of midrange applied to a channel signal, turning the knob in a clockwise direction will increase the amount of midrange applied to a channel signal. 5. CHANNEL BASS CONTROL - This knob is used to adjust the low frequency levels of a channel allowing for a maximum bass gain of 1 2 dB or maximum signal decrease of -30dB. Turning the knob in a counter-clockwise direction will decrease the amount of bass applied to a channel signal, turning the knob in a clockwise direction will increase the amount of bass applied to a channel signal. 6 . MASTER OUTPUT BALANCE CONTROL - This knob is used to control the pan, adjust how much of the signal is sent to the left and right output level. For true stereo imaging, maintain the knob in the 12 o’ clock position. 7. 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 out - put volume control. 8. ZONE TREBLE CONTROL - This knob is used to adjust the low frequency levels of the ZONE allowing for a maximum bass gain of 1 2 dB or maximum signal decrease of -12 dB. Turn- ing 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. 9. ZONE BASS CONTROL - This knob is used to adjust the treble levels of the ZONE allowing for a maximum treble gain of 1 2 dB or maximum decrease of -12 dB. Turning the knob in a counter-clockwise direction will decrease the amount of treble applied to the ZONE signal, turning the knob in a clockwise direction will increase the amount of treble applied to the ZONE signal. 10 . MASTER OUTPUT MONO/STEREO SWITCH - This switches the Master Output signal between stereo and mono. 11. LCD SCREEN - FOR INFORMATION SEE PAGES 15-17. 12. DSP EFFECTS (DIGITAL SIGNAL PROCESSING) - FOR INFORMATION SEE PAGES 15-17. 13. 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 ( 17) will also work in conjunction with function. Please note that this function will only work with a set of stereo headphones. 14 . 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 (15 ) is set to minimum before you put the headphones on. 15 . 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. 16. CROSSFADER FX ACTIVATOR - When this button is activated it transfers control of the the DEPTH FEEDBACK DIAL (65) to the CROSSFADER (21). While this function is engauged the DEPTH FEEDBACK KNOB (65) will not function. When this function is engaged, you are not able to store pre-set parameters. Q-FX19™ CONTROLS AND FUNCTIONS cont. ©American Audio® - www.americanaudio.us - Q-FX19™ Instruction Manual Page 9
©American Audio® - www.americanaudio.us - Q-FX19™ Instruction Manual Page 10 17. 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 PFL (19) function is selected. To select a channels cue function press the PFL 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 position (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. 18 . 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. (see Channel Gain 2 ) 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. 19 . PFL (CUE SELECTOR) BUTTON - These buttons are used to activate a channels “CUE” mode. A red LED next to the Cue button 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 ( 15). Be sure the CUE MIXING SLIDER (17) is set to the “CUE” position to hear a selected chan- nel source. 20. FADER “X” ASSIGN BUTTON - This button assigns a channel to the left side (X) of the CROSS- FADER ( 21). When a channel is assigned to the left side of the CROSSFADER (21) that channels output level is routed to and controlled by the CROSSFADER (21). Sliding the CROSSFADER (21) to left position will send the assigned channels volume output to the MASTER VOLUME LEVEL ( 18) and sliding the CROSSFADER ( 21) to right position will cut that channels volume to MASTER VOLUME LEVEL (18). 21. 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. 22. FADER “Y” ASSIGN BUTTON - This button assigns a channel to the right side (Y) of the CROSS- FADER ( 21). When a channel is assigned to the right side of the CROSSFADER (21) that channels output level is routed to and controlled by the CROSSFADER (21). Sliding the CROSSFADER (21) to right position will send the assigned channels volume output to the MASTER VOLUME LEVEL (18) and sliding the CROSSFADER ( 21) to left position will cut that channels volume to MASTER VOLUME LEVEL (18). 23 . 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 (18). 24 . Q-START ON/OFF SWITCH - 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 ( 21). The ON/OFF Q-FX19™ CONTROLS AND FUNCTIONS cont.
