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

There are occasions when a number of mono sources or a stereo source and/or instruments need to be mixed down into a mono signal.

Condenser microphones usually specify different requirements for their phantom power.

Most home recordings involve from one to four people, any or all of whom are going to need headphone monitoring.
