 DV2 USB                                                          USB  audio Interface
Use of the DV2 USB audio interface can be used in several modes to mix computer audio fr om 
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 
drive can also be downloaded directly by visiting DV2 product page at www.adjaudio.com.
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.

CC-aBSOLUte (Vr)
Control Change messages are sent with status 0xBn, where “n” is the channel, for the specified CC 
controller. Thus the controller MIDI ID is indicated with the channel along with the CC number. The 
value from 0x00 to 0x7F, is directly related to the location of the controller.
SWItCh On/OFF (SW, Center, CW, CCW)
These messages are used for switches. Control Change messages are sent with status 0x9n, 
SWITCH On and Off value are 0x7F and 0x00, where “n” is the channel.
LeD On/OFF (LeD)
These messages are used for LED. Control Change messages are sent with status 0x9n, LED On 
and OFF value 0x7F and 0x00, where “n” is the channel.
LeVeL LeD (LeVeL)
These messages are used for LEVEL. Control Change messages are sent with status 0x9n, LED 
Off value is 0x00 and On value is related to LED amount, 0x01 with one LED, 0x02 with two LED...., 
where “n” is the channel.

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).
