features
The HP-Eight 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 capa-
bilities 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 cre-
ate the overall mix.The use of groups allows the operator to easily control and
modify collections of instruments or voices. Examples include: drum mixes, back-
ground 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 chan-
nel’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 equalization or com-
pression can be applied to that collection of signals by patching external process-
ing 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
L-R Bus Assign
The output of the Group feeds the L and R main buses via this Pan Pot, in con-
junction with the L-R Bus Assign switch.The feed to the L & R buses is post-fader,
post-mute.
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.
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 FLIP switch is depressed,
then this mute switch will affect the associated Aux output (See Fader Flip
description).
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 FLIP 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 Flip description following).
