groups (audio subgroups)
6
features
The HPW is equipped with 8 audio subgroups, in addition to the main L/R and Mono
mix buses. All of the Inputs (Mono and Stereo) have full assignment capabilities to all
11 of these mix buses. Typically, these 8 groups are used to create sub-mixes within the
main program. These sub-mixes are then combined to create the overall mix. The use
of groups allows the operator to easily control and modify collections of instruments or
voices. Examples include: drum mixes, background vocals, choir microphones, etc. Since
the group assignment is done in odd-even pairs (1-2, 3-4, 5-6, 7-8), stereo subgrouping is
typically used. Each input channel’s pan pot is used to create a stereo sub-mix within an
odd-even group pair. After assigning related signals to a pair of groups, specific equaliza-
tion or compression can be applied to that collection of signals by patching external
processing gear into the groups’ insert jacks (stereo EQ or compressors are often used).
That processed, stereo-group signal can then be assigned to any of the 3 main mix buses
(L/R/Mono) via the group’s bus assignment switches, to create the final mix. The feed to
the L-R buses is Post-fader, Post-mute through the Group Pan-Pot, the assignment to the
Mono bus is Post-fader, Post mute; the Pan-Pot is not involved.
Group Pan Pot
This control determines the group’s placement in the L-R stereo sound field. The control
only functions when the group is assigned to the L-R bus. It always has the group signal
and is unaffected by the fader reverse switch.
Mute Switch w/LED
This switch normally will mute the post-fader output of the audio group. The LED will
illuminate when the mute is active. If the FADER REVERSE switch is depressed, then
this mute switch will affect the associated Aux output (See Fader reverse description).
Note: This mute is NOT part of the programmable mute scene system
Mono Bus Assign
The output of the Group feeds the Mono bus when this switch is depressed. The feed to
the Mono bus is post-fader, post-mute.
L-R Bus Assign
The output of the Group feeds the L and R main buses when this switch is depressed.
The Group Pan pot controls the L-R position. The feed to the L and R buses is post-
fader, post-mute.
100mm Fader - This high-quality, 100mm fader is used to control the Group output
level. Any Post-fader feeds are affected by this control. Nominal position is at the “0”
mark, with 10dB additional gain available above that point. When the FADER REVERSE
switch is depressed, this fader will control the associated Aux output level, and the Group
output level is then controlled by the Aux Level rotary pot (See Fader reverse descrip-
tion following).
