USING VARIOUS INSTRUMENTS
The J48 Stereo is active. This means that it has a built-in preamp or buffer circuit that drives the signal. This is the benet
of an active direct box over a passive counterpart. In other words, if you have a passive source such as an old Fender
bass, the J48 Stereo presents a very effective interface. Many sound engineers also prefer the added gain of an active
direct box on active instruments such as with acoustic guitars and vintage keyboards that may not have the optimal output.
In some instances the J48 Stereo can also improve signal to noise.
