Q-SD QUICK START INSTRUCTIONS

QUICK START: American Audio® would like to thank you for your purchase of this great audio product. 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-SD 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 constructed of

the nest 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 your 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 maximum 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 (13) is set to minimum before plugging them in. To avoid sever hearing damage, never put the headphone 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 independent 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 VOLUME

KNOB (22). Note: We recommend that you use a 500-600ohm microphone for the best sound quality.

2. SOURCE SELECTOR SWITCH - These switches are used to select the input source assigned to

each channel. Each channel may only be assigned one input source at a time. This switch must be in the “phono” position for turntable operation.

3. 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 (5) is set to level 8.

2. Set the CHANNEL FADER (19) 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

4. CHANNEL EQ SECTION -

CHANNEL TREBLE CONTROL - This knob is used to adjust the treble levels of a channel

allowing for a maximum treble gain of +12dB or maximum decrease of -30dB. Turning the knob in a counter-clockwise direction will decrease the amount of treble applied to a channel signal, turning the knob in a clockwise direction will increase the amount of treble applied to a channel signal.

CHANNEL MIDRANGE CONTROL - This knob is used to adjust the midrange levels of a channel 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.

CHANNEL BASS CONTROL - This knob is used to adjust the low frequency levels of a channel allowing for a maximum bass gain of +12dB 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.

5. MASTER VOLUME CONTROL - This fader 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 +4dB. 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.

6. MASTER OUTPUT MONO/STEREO BUTTON - This button switches the Master Output signal between stereo and mono.

7. 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.

8. MASTER VOLUME LEVEL INDICATORS - The dual MASTER LEVEL LED indicators are used to detail the master fader output level. The meters will detail the output level of both the left and right channels.

9. POWER SWITCH - This is the main power ON/OFF switch. Before you turn the power on be sure you have made all connections to the mixer. Also be sure you amplifiers are turned off. Remember mixer on first and turned off last.

10. SD PLAYER & LCD - This is the SD Player, Controls, and LCD. The player and LCD will be explained on pages 12-14.

11. AUX 4 INPUT JACK - This Aux input is for the use of a Mp3 player, or satellite radio. Input volume will be controlled by the channel four fader. The channel SOURCE SELECTOR SWITCH (2) must be in the "Aux 4" position, to monitor any source connected to this jack.

12. 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 (13) is set to minimum before you put the headphones on.

13. 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.

14. 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 (20) function is selected. To select a channels cue function press the CUE BUTTON (20) 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

Q-SD FRONT PANEL - CONTROLS AND FUNCTIONS CONT.

either hear more or less of either of the two levels. Turning the Cue Mixing knob to the CUE position (left) will allow you to hear more of the Cue level. Turning 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 knob is in the full CUE position you will only hear the cue level, if the knob is in the full PGM position you will only hear the main output. This function is especially useful when mixing without an monitor.

15. 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.

16. FADER ASSIGN SWITCH - This is a five position switch that assigns a channel to the CROSS- FADER (18). When a channel is assigned to the left side of the CROSSFADER (18) that channels

output level is routed to and controlled by the CROSSFADER (18). Sliding the CROSSFADER (18) to left position will send the volume output of the assigned channel to the MASTER VOLUME LEVEL (5), siding the CROSSFADER (18) to right position will cut that channels volume to MASTER VOLUME LEVEL (5). 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.

17. 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 (18). The ON/OFF “Q" START SWITCH activates the FADER “Q" START feature. When in the ON position, 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 A and B. When the Fader "Q" Start option is turned on, sliding the crossfader to the far left position will trigger playback on CD player A. When the crossfader is pushed to the far right position, playback on CD player B will begin, and CD player A will return to the cue position. Refer to your American Audio CD player user manual for setting CUE POINTS. Turn the ON/OFF SWITCH to the OFF position to disengaged “Q” Start function and resume to a normal fader.

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

19. 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 (5).

20. CUE BUTTON - These buttons are used to activate a channels “CUE” mode. A red LED around 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 (13). Be sure the CUE MIXING KNOB (14) is set to the “CUE” position to hear a selected channel source.

21. MIC 2 VOLUME CONTROL - This knob controls the output volume of MICROPHONE 2 (53). However, master volume is controlled by the MASTER VOLUME CONTROL (5).

22. MIC 1 VOLUME CONTROL - This knob controls the output volume of MICROPHONE 1 (1).

Q-SD FRONT PANEL - CONTROLS AND FUNCTIONS CONT.
