have attempted to provide you with the most reliable product on the market by using only components
constructed of the nest material.
MASTER LEVEL (2) - Use this level control to set your master 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.
PHONO/LINE SELECTOR SWITCH (7) - This switch is used to change the selected input
from phono level to line level and vice versa. Channels 1 and 2 may be switched PHONO or LINE.
Use “LINE” for line level devices such as CD players and tape decks. Use “PHONO” for magnetic
turntables only (DJ turntables).
CHANNEL GAIN LEVEL (4) - 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.
HEADPHONES (10) - To avoid damaging your headphones always be sure the headphone volume
level (1) 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.
MIC (13) - The mic connector uses a 1/4” plug that allows you to connect a 1/4” unbalanced mic
cord. The mic also has an independent volume control. Always leave the mic level to it’s minimum level
when not in use.
Q-START FEATURE - This function works in conjunction with a compatible American Audio

channel is assigned to the left side of the CROSSFADER (12) that channels output level is routed to
and controlled by the CROSSFADER (12). Sliding the CROSSFADER (12) to left position will send the
volume output of the assigned channel to the MASTER VOLUME LEVEL (2), siding the CROSSFADER
(12) to right position will cut that channels volume to MASTER VOLUME LEVEL (2). 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.
12. FEATHER FADER PLUS CROSSFADER - This fader is used to blend the output signals of channels 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 channel 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 channel

signal to your amplier or tuner. When connecting to a tuner be sure to use the “AUX” inputs.
28. AC VOLTAGE INPUT - This connector is used to supply main power to the unit via the included
detachable power supply. Only use the supplied power adaptor to avoid damaging the unit. The unit
receives an input power supply of AC 9v/1000mA.
29. MAIN POWER SWITCH - This is the main power ON/OFF button. Before main power is applied,
be sure you have made all connections to the mixer. Also be sure your amplier(s) is tuned off. Remember to avoid damaging pops, mixer on rst and turned off last.

Q-D1 PRO CLEANING
Due to fog residue, smoke, and dust, cleaning the mixer should be carried out periodically to optimize
light output.
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.
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).
Q-D1 PRO CROSS FADER REPLACEMENT
The crossfader is “Hot Changeable” which means it may be replaced at any time, even when power
is applied. Only replace with American Audio Feather Fader Plus. Replacing with any other model
fader may seriously damage your mixer.
Replacing the Crossfader:
1. Using a number two Phillips screw driver, unscrew the each of the stainless steel retaining
screws that hold the crossfader in place.
2. Gently remove the crossfader from its seated position. You may need to wiggle the crossfader
slightly to unseat it.
3. After removing the crossfader, disconnect the ribbon cable that attaches the crossfader to the
PC board. Grasp the crossfader by its base and pull the ribbon cable by its connector not the
actual cables. The connector is desired to only t one way, so don’t worry about the connectors
orientation.
4. Connect the new crossfader to the ribbon cable.
5. Reassemble in reverse order.
