GROUP AND REVERB CHANNEL STRIPS
1
3
Group busses can be used to create a mix sub-
group, which is a set of inputs you wish to
control together as a group. Groups differ from
aux busses in that they have aux sends, a reverb
send, as well as a main mix send. In addition,
group busses are equipped with the Leveler.
The Reverb bus is a special group bus that
provides a reverb processor. If you disable the
reverb, the reverb bus functions as a (fourth)
regular group bus.
To access the Group and Reverb bus channel
strips, go to the mixer tab (page 21), reveal the
side bar (item #3 on page 21), and then show
the desired Group busses or Reverb bus in the
Mixer Outputs section (26).
To show and hide the four-band EQ section of
the channel strip, use the Controls section of the
side bar (item #3 in the mixer tab on page 21).
1. A Group bus channel strip. Click the name to
rename it. Delete the current name to return
to its default.
2. The Reverb bus. If you disable the Reverb
processor, it can be used as a fourth Group
bus. The Reverb channel strip is twice as
wide as other mixer channel strips to
accommodate the Reverb processor
controls.
3. Group busses and the Reverb bus are always
stereo.
4. The four-band parametric EQ module for
Group busses and the Reverb bus operates
the same as described for input channels
(items 10 and 11 on page 23), including
High and Low Shelf filter options.
5. The Reverb processor. For complete infor-
mation, see “Reverb” on page 73.
6. Main Mix sends.
7. Master faders for the Group and Reverb
busses.
8. Mute and Solo.
9. Use these menus (hardware settings, output
assignment, and presets) in a similar
fashion as described for the Main Out bus
(items 3-5 on page 24).
