The Zdirect is a high quality totally passive interface that lets you connect
instrument, line, or speaker level signals to a mixer or other balanced input
thru a high performance audio isolation transformer. The high impedance
single-ended 1/4” input is converted by the transformer into an isolated balanced
low impedance signal source. The Zdirects audio transformer has an extremely
flat and wide frequency response and can handle high signal levels while still
maintaining an isolated balanced low impedance output. This gives the Zdirect
a very clean and neutral sound with a wide variety of signal sources and over
long signal runs in high noise environments
