Know before you buy
No, the ProD2 is a passive device. It does not require batteries, external power, or phantom power to function.
Yes, the ProD2 is specifically designed for stereo instruments like keyboards. It converts your unbalanced 1/4-inch instrument signals into balanced XLR signals that can run long distances to your mixer without noise.
That buzzing is often caused by a ground loop. Simply engage the Ground Lift switch on the ProD2 to disconnect the signal ground path and eliminate the hum.
The pad switch reduces the input signal level by 15dB. It is useful when connecting high-output instruments or devices that might otherwise cause distortion or 'clip' the input of your mixer.
Yes, you can use the ProD2 as a single-channel DI if you only have one instrument. Additionally, the unit features a 'sum' function that allows you to combine stereo inputs into a single mono output if your routing needs require it.
