channel muting features
The HP-Eight is equipped with a 4-Scene muting system.An input channel can be
assigned to any of the 4 available scenes (A thru D).When the Mute Scene
Master switch (located in the Master module) is depressed, all channels assigned
to that scene will mute. In addition, the local channel mute switch can be used to
kill the output of the channel independently of any of the scenes.
MUTE (Local Mute)
Pressing this switch will mute the output of the channel to any of the assigned buses
and any Aux sends.
MUTE LED
The associated red-LED will light when the channel is muted either by its local mute
switch, or when part of an active Mute Scene (A thru D).
A ( Scene Mute Assign)
Pressing this switch will assign the channel to Mute Scene A.The channel will mute
(and MUTE LED will illuminate) when the Master Scene Mute A is active.
B, C, D ( Scene Mute Assign)
Same operation as A for switches B thru D
channel monitoring features
The channel is equipped with a bicolor LED that displays the channel’s Pre-fader
signal level with varying intensity green illumination, and also indicates impending
channel overload (within 3dB of clipping) by turning red. Channel clipping is
sensed both pre and post fader, so even if the fader is down, you will be informed
of any preamp or EQ related overload problems.
A PFL (Pre-Fader Listen) switch is provided that lets the operator monitor the
channel’s signal in the Console’s Solo system.When depressed, the channel’s pre-
fader signal sent to the Console’s Solo system (See Master section for details on
the Solo system functions).
PK/Sig LED
Pre-Fader signal is shown as varying GREEN intensity, channel clip warning shows
as RED.
PFL
When this switch is depressed, the channel’s pre-fader signal is sent to the
Console’s Solo system.The channel LED is lit RED to indicate that the PFL is active.
The Solo meters will now show the channel’s PFL level.

NOTE:
Do not write directly
on the Console’s surface with
a Sharpie or other permanent
marker. Use a china-marker
(grease pencil) or other
removable marking pencil, or
put down a strip of Artist tape
first. Avoid using standard
masking tape; it dries out and
leaves a hard-to-remove glue
residue.

®
The signal present cir-
cuitry is at the top of the
channel fader, so it sees the
audio path: from the preamp,
into the lo-cut filter, through
the insert jack and finally
through the EQ. The signal
path has to be intact through
all these stages in order to
get the green LED illuminat-
ed. Any gain changes or
audio processing will affect
the signal-present LED. Also,
since the PFL feed is taken
from this same, pre-fader
point, the Solo meters and
Solo headphones will moni-
tor this overall channel
signal
.
