Chapter 9: Groups 103
Group Output Polarity Invert (Phase
Reverse)
The polarity of any Group output bus signal can be inverted
(Phase Reverse). With stereo Group busses, only the left channel
is inverted.
To invert the polarity of a Group from Channel Control:
1 Press Bank switch F to bank Groups to the channel strips.
2 Press the channel Sel switch for the Group you want to con-
trol.
3 Make sure the main Channel Control menu is shown in the
Channel Control displays.
4 Press the Channel Control encoder under the display showing
Input.
5 Press the Page > Channel Control Navigation switch to access
the second page of Input parameters.
6 Under the display showing Polarity, press the encoder In
switch to toggle polarity in/out. The switch LED lights green
when the channel’s polarity is inverted (Phase Reverse is en-
abled).
Group Output Delay
A variable delay (from 0 to 500 ms) can be applied to Group bus-
ses. With stereo Group busses, delay is applied to both channels.
To apply delay to a Group:
1 Press Bank switch F to bank Groups to the channel strips.
2 Press the channel Sel switch for the Group you want to con-
trol.
3 Make sure the main Channel Control menu is shown in the
Channel Control displays.
4 Press the Channel Control encoder under the display showing
Input.
5 Under the display showing Delay, rotate the encoder to set the
desired amount of channel delay.
6 Press the corresponding encoder In switch to toggle channel
delay in/out. The switch LED lights green when channel delay
is on (enabled).
Group Bus Signal Flow Options
Routing Signals to a Mono Group Bus
Configuration
When configured as mono busses, the eight Groups can be fed as
8 unlinked mono busses or up to 4 linked odd/even bus pairs.
Unlinked Mono Busses
To use unlinked mono Group busses:
1 Make sure the Group busses are configured as mono busses.
See “Configuring Aux and Group Busses” on page 88.
2 While routing channels to Group busses, make sure the Stereo
Pan switch is off.
The Group switches in the on-screen Bus Assign section light
green to indicate mono operation. In this configuration, input sig-
nals are handled as follows:
Mono Input Signals Contributing mono signals are summed to
the mono Group bus. Any pan information from mono input
channels feeding the bus is ignored.
Stereo Input Signals Contributing stereo signals are summed to
the mono Group bus with no attenuation. The balance and width
information from each stereo input channel is ignored.
Linked Odd/Even Bus Pairs
To use linked mono Group bus pairs:
1 Make sure the Group busses are configured as mono busses.
See “Configuring Aux and Group Busses” on page 88.
2 While routing channels to Group busses, press the Stereo Pan
switch so that it lights yellow.
The Group switches in the on-screen Bus Assign section and the
Stereo Pan LED in the channel’s Bus Assign indicator light yel-
low to indicate stereo operation. In this configuration, input sig-
nals are handled as follows:
Mono Input Signals Contributing mono signals are panned
across the linked odd/even Group bus pair. Pan information from
each mono input channel determines its pan position in the bus
pair.
Stereo Input Signals Contributing stereo signals are panned
across the linked odd/even Group bus pair. Balance and width in-
formation from each stereo input channel determines its contribu-
tion to the odd and even sides of the bus pair.
Press the Back/Top Channel Control Navigation switch to
return to the Channel Control main menu.
