Quick Start Instructions  
American Audio would like to thank 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 DV2 USB is part of American Audio’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 using only 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. 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 trim levels are not to be used as volume controls, never use the  
channel gain 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 severe hearing damage, always be sure the headphone level is set to mini-  
mum before plugging them in. Never put the headphone on without making sure the headphone level  
is turned down.  
MIC - The mic connector uses a 1/4” jack unbalanced connector. The DJ mic has an independent  
volume control. When feedback occurs when using the mic, try lowering the “low” level this may  
reduce the feedback. Always leave the mic level to it’s minimum level when not in use.  
PhOnO/aUX SWItCh (25) - 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/AUX or LINE. The selectors for  
AUX1/PHONO1 and AUX2/PHONO2 are on the rear panel.  
Q-Start FeatUre - This function works in conjunction with a compatible American Audio or Ameri-  
can DJ “Q”Start CD player. When used with a compatible CD player, you can use the crossfader to  
start and stop the CD Player with the slide of the fader. The ON/OFF “Q ”START switch activates this  
FADER “Q ”START feature.  
CrOSSFaDer CUrVe aDjUStMent- This rotary knob is used to change the way the crossfader  
will operate. The crossfader can operate in three different modes, NORMAL CURVE, QUICK CURVE  
and any variation of the two. (Quick Curve usually used for crabbing).  
ChanneL FaDer CUrVe aDjUStMent - This rotary knob is used to change the way the channel  
fader will operate. Each channel has a Curve adjustment. The curve on the faders adjust from long or  
short or any variation of the two.  
reVerSe FUnCtIOn - Both the crossfader and the channel faders will reverse function when the  
reverse switch is activated.

1. MaSter VOLUMe COntrOL - This rotary knob is used to control the master output level (volume).  
To avoid distorted output try to maintain an average output signal level +4 dB. Be sure this volume  
control is always set to zero before turning the unit on.  
2. CUe MIXInG COntrOL - This knob selects the channel for monitoring. The monitor signal comes  
from the Prefader. This means it will not be affected by the channel faders. You can monitor each chan-  
nel individually. Connect your headphones to the HEADPHONES jAck (36). Turn the CUE MIXING  
CONTROL to CUE and select the desired channels with the PFL switches. When you turn the CUE  
MIXING CONTROL to PGM (PFL switches without function), you can cue the output signal of the mixer.  
If the CUE MIXING CONTROL is set to the center position, you can cue both the channel signal you  
selected and the output signal.With the CUE LEVEL control, you can adjust the phones volume without  
changing the output signal.  
3. 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.  
4. MIDI BUttOn - This button activates the MIDI function.  
5. LeVeL InDICatOr MODe SeLeCtOr - This button is used to change the operating mode of the  
LEVEL INDIcATORS (15). When the switch is in the Master L/R position, the meter will indicate the  
master output levels. When the switch is in the PFL CH1/CH2 position the meter will use the left side  
of the meter to indicate channel one’s prefader level and use the right side of the meter to indicate  
channel two’s prefader level.

USB audio Interface  
Use of the DV2 USB audio interface can be used in several modes to mix computer audio from  
media player software. You may use the DV2 as your default sound card, or in the media player  
options set the mixer as the speaker output for the desired media player. Note: Some media play-  
ers may not have this option. Most commonly the USB audio interface may be used with one of  
the many DJ software programs that are available for computers. American Audio has provided  
software to get you started.  
aSIO DrIVer InStaLLatIOn:  
Most Windows based computer systems will not support multiple channel USB audio routing. Asio  
drivers are necessary to support multiple sets of stereo outputs. Enclosed with the provided soft-  
ware CD you will find Asio driver installation software for 32 and 64 bit operating systems. The Asio  
Mac users do not need ASIO drivers. Multiple channel streams are supported with core Audio.  
rOUtInG USB aUDIO:  
The DV2 is equipped with a built-in 4 in/4 out USB audio interface to integrate the use of the ever  
growing popularity of DJ software, Digital Vinyl systems, Media Players, or Production software into  
your mix.  
eXternaL aUDIO rOUtInG:  
With the MIDI turned “Off” on the DV2, channel 1 will receive the audio that is assigned to USB  
channels 1 & 2. Channel 2 will receive the audio that is assigned to USB channels 3 & 4. Note: Not  
all software supports this set up, check the audio routing under your software options.  
The RCA inputs are routed to the USB inputs. The signal sent to the USB is dependent of the Source  
Selector Switch. To allow the use of the DVS software when the source select switch is set to USB,  
the RCA Phono/Aux inputs are routed to the USB inputs, this allows you to route the RCA input sig-  
nals through software and layer them with your favorite software FX.  
To record with DAW software for sampling, the USB input will route the selected source to the soft-  
ware USB input. Check your software manual to set up the DV2 as the input source for recording.  
Note: When recording a RCA Phono/Aux can be monitored thru the USB setting. Do not make  
adjustments to the Gain or EQ of the channel when auditioning audio, this will affect record levels.  
Recording levels should be set to the desired level beforehand.  
MIDI anD InternaL aUDIO rOUtInG:  
When MIDI is enabled on the DV2 the USB Audio is routed to function with software that supports  
MIDI and requires internal audio routing. This mode will route the sound from your software, and  
the volume levels will be controlled via the MIDI parameter on the MIDI controls. The headphones  
become USB channel dependent make sure to assign Asio/Core channels 3 & 4 to your software’s  
headphone output.

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. Clean 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).
