VOXOA A50 CONTROL PANEL ASIO driver Control Panel: When you use the ASIO Driver supplied accordingly, open the ASIO-USB Control Panel in your computer. When you have the driver installed an icon will appear at the lower right of your PC Open it with mouse right button and you can view the ASIO-USB Control Panel ENGLISH It is very important that you understand well the Control Panel since it is where you change the settings of your sound card VOXOA A50 CAUTION : If you press "Gang" both sliders will move like one. If you press "Mute" the IN/OUT is muted Headphone Output Level: 1+2: sets the A50 Headphones Output level of VOXOA A50 Channels 1 and 2 3+4: sets the A50 Headphones Output level of VOXOA A50 Channels 3 and 4 28 This is the internal HP level (Inside your computer). You also have an analogue potentionmeter to further adjust the Headphone Output level (See page when the audio signal is converted from digital to analogue.) Upon your DJ Software use mode you'll have to adjust the HP Output accordingy.

VOXOA A50 CONTROL PANEL NOTE: ALWAYS turn down the analogue Headphones level (See page before using them. The Output level is high enough to damage your hearing. MIC Level: VOXOA A50 has two electronic paths for Microphone, one analogue and one digital (converted into digital signal and processed by your computer software) Gain: sets the Microphone Input sensitivity prior to be digitalized into your computer. Similar to a normal Gain on a mixer. For proper level setting, the precessing software on your computer shall have a level meter so you can optimize your dynamic range as is usually done with the Gain of a Mixer channel ENGLISH Through: controls the analogue electric path of the Mic signal. We will take care of these issues later in this manual NOTE: If you press MUTE the IN/OUT is muted Input Level: VOXOA A50 has two Input level controls; one for channels 1+2 and one for channels 3+4. Similar to a normal Gain on a mixer. For proper level setting, the processing software on your computer shall have a level meter so you can optimize your dynamic range as is usually done with the Gain of a Mixer channel A50 Output Level: VOXOA A50 has two Output level controls; one for channels 1+2 and one for channels 3+4.
