Appendix B - If You Use An External Mixer...

Our main objective is to get the signal we want to record to the Delta 1010, and
to monitor the outputs from the Delta 1010. The 1010 has a mixer contained on
its chip that allows you to mix hardware inputs and software outputs and send it
to an analog stereo output pair and/or the S/PDIF out. The 1010 also allows you
to record that mix into your music software as a hardware input. Still, some of
you may choose to use a mixing console to achieve your multi-tracking goals.
A mixing console (sometimes referred to as mixing 'board' or 'desk') that is
designed for multi-track recording has the ability to fulfill these two basic
functions -- getting the signal to the recording device, and receiving the outputs
of that recording device for mixing or monitoring. In this sense, a recording
console is two mixers in one. A mixer designed for recording will also have the
ability to send to one or more mixdown decks, to monitor these mixdown decks,
to control separate control room and studio listening levels, as well as other
recording-specific functions.
There are two basic layouts for the recording console, "split section" and "in-
line." The split section design is arranged with a recording or 'channel' section
(to send the signal to the recording device) side-by-side with a monitoring
section (to receive the outputs of the recording device). The in-line design has the
recording and monitoring sections "in line" within each channel module, so that
each channel has two line inputs.
The recording section is distinguished by its bussing system, which takes the
recording channel signal through a summing matrix to multiple outputs- usually
in multiples of eight. It could be said that an '8-buss system' is designed for 8
track recording, and a 24-buss system for 24 track recording, etc., but this is not
written in stone.
What we are describing here is the extreme- a professional, costly piece of gear
that has been purchased for this one specialized purpose. There are features
inherent in other types of consoles, however, that will allow us to perform these
two separate functions of recording and monitoring. A sound reinforcement or a
broadcast console, and in some cases a recording console, might offer a bussing
