This diagram illustrates two standard DI applications. The signal going to the amp via
the DIRECT LINK is unaffected; it is simply picked up and additionally fed, as a balanced,
low-impedance signal, to the mic inputs of the mixing console. This is particularly
advantageous with bass guitars, since microphones that reproduce high-energy bass
frequencies in a halfway linear manner are rare—and expensive. When using effects or other
outboard processors, these should be connected in front of the ULTRA-G in the signal path,
so that its output includes these signals.
Few keyboards have balanced outputs. Here, a quality DI box such as the GI100 is indispensable
to ensure clean signals, especially when using long cables.
