Passive Direct box with PA
Connect the hi-Z output from your keyboard to the DB-2PX and it will lower the impedance and balance the signal for long cable runs. It also eliminates hum and buzz caused by ground loops.
Laptop DI to PA system
Send the stereo output from your laptop, CD player or DJ mixer to the DB-2PX and it will deliver a balanced mic level output to feed a mic splitter or the mic input of your mixing console without noise or distortion.
DB-2PX in the studio
The high input impedance, exceptional signal handling and broad frequency response make the DB-2PX a great choice for interfacing electric bass or acoustic guitar to the PA or recording system.
