The Mixer Output Guide
Courtesy of Silent Way Remote Audio Recording and Audio Equipment Rental.
Audio mixer inputs are well documented, but output specifications are buried in manuals. This guide to the poor neglected output describes direct outs, inserts, hidden mods and more.
There are two ways to do a live recording: use a mic-splitter with dedicated mic preamps, or hope that the direct outputs on the house board don't suck. House direct outs are risky if they're post-fader/EQ, inaccessible, bad mic pres etc. Whether you call it a console, mixer, board or desk, plan ahead with this list. Your contributions and corrections are encouraged.
TS/RR: tip=send, ring=return. A "first click" insert is a semi-direct out: an unbalanced 1/4" TS plug inserted half-way will send signal without interrupting it to the mix bus. Plugged all the way in, it is a direct out which interrupts.
