Chapter 7: Busses and Bus Masters
The number of busses and channels available in your System 5 configuration is determined by the processing power in the DF66
Super Core (number of cards) or the DF70 (if used instead) and the Mixer Model: more channels = less busses and vice versa. See
“Choosing a Mixer Model” on page 28 for a complete discussion of these system resource issues.
System 5 has four bus types: Mix, Group, Aux, and Solo.
Mix Busses
A maximum of 96 Mix Busses can be configured in up to 16 Mix Sections. Each Mix Section can have between one and eight in-
dividual busses (i.e., a stereo pair uses two, and an LCRS set uses four) and can be set to any format. Mix Busses have playback re-
turns; Aux and Group busses do not.
Group Busses
Group Busses route channels to multitracks, DAWs, mix-minus feeds, and sub-groups. Group Busses can be configured to any for-
mat but are usually set to odd/even stereo pairs. With Pan switched out, they act as mono assign busses.
Auxiliary Sends
Aux sends are used for effects, foldback, and mix-minus feeds. Aux sends can be configured as mono or stereo pairs, pre- or
post-fader.
Solo Busses
The Solo bus is fixed at stereo. After-Pan Listen (APL) and Pre-Fader Listen (PFL) route signals to the Solo Bus. Each Strip’s fader
also has a Backstop PFL function: move and hold the fader past the bottom of its travel to activate the PFL Solo mode (see “Back-
stop PFL” on page 72). Solo In Place (SIP) is a destructive Solo mode and does not use the Solo busses. See “Solo Mode” on page 49
for more information on SIP.
