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.
