The DB100 Laptop DI Box eliminates noise and ground loops that often occur when using consumer audio devices with a PA system. Simply connect its 3.5 mm plug to the headphone jack of a laptop or digital music player, and this compact DI automatically converts the audio signal to a balanced, mic-level XLR output suitable for use with high-powered amplifiers. The volume knob enables additional adjustment of the output level while the ground-lift switch provides control over hum caused by ground loops. Passive and transformer based, this DI does not use a power supply and delivers electrical isolation for convenient, reliable sound preservation.
