15Using the Level ControlsThe Q2U employs Up and Down Level controls,which are normally used to control the levelof the internal headphone amp, howeverthe Level controls will adjust the volume ofwhichever device (Q2U or internal sound card)is set up as the output. If you set the Q2U as theoutput device, the Level controls will adjust theheadphone output. If you select the any of thecomputer’s internal soundcards as the outputdevice, the Level controls will adjust the output volume of computer via that device.Now, use the Up and Down switches to raise or lower the volume respectively.Setting Up the Signal LevelYou can adjust the Q2U’s internal analog input gain stage by using your softwareDAW or operating system. The purpose of the level, or gain controls are to optimizethe amount of good signal relative to any associated noise. A good mic or instrumentpre-amplifier, like the one inside Q2U, will also have a PEAK indicator to show whenthe input signal is clipping. To set a good level on the mic, set the Q2U up in front ofthe desired sound source and slowly raise the DAW’s or operating system’s input gaincontrol until you see the CLIP or Peak indicator light up. Then, turn the input trimcontrol down until the indicator does not light any more. Once you set the input levelcontrol you shouldn’t need to change them during recording. Use the level controls onthe DAW to set the balance between the mic and stereo mix during playback.Operating the Q2U
