2. Description
• Studio/DJ mixer: using more than one mixer in a studio means you might face hum noise from your line level
gears. With the VDSM03 the sound will be clean.
• Live sound: unbalanced cables are frequently used in live situations. Hum noise might be caused by such
unbalanced cables, amplifiers or guitars. With the VDSM03 you can balance the signal.
• Computer sound card: most sound cards use unbalanced in and outputs. Using the VDSM03 can help you to
balance them and to prevent the ground loops by the computer's power supply.
