Master Section: Monitoring & Control
Solo Operation
The HP-Eight is equipped with a stereo solo bus that allows the operator to monitor the
various signals within the Console.All Input channels have a PFL (Pre-Fader Listen) switch,
Outputs are equipped with an AFL (After-Fader Listen) switch.The PFL circuit on the
Inputs allows the operator to properly set the channel’s internal signal level using the chan-
nel’s Gain pot and Pad switch. Since the signal being monitored is PFL, the channel fader
level, as well as any bus assignments, is ignored.This allows a channel to be monitored and
adjusted without being sent into any of the main mixes.The operator has a chance to
properly set the levels and EQ of a channel before anyone else might hear it.
For Outputs, the AFL signal point allows the operator to hear exactly what is being fed to
the outside world.The output level, as well as any inserted processing gear, can be moni-
tored by the Solo system. For the times that a Pre-Fader point needs to be checked, the
Monitor Sources can be used to listen to a bus before its main fader.
Solo Metering
Whenever a Solo button is pressed (PFL or AFL), the SOLO LED indicator will illuminate
and the Monitor Source LED meters will switch-over to display the Solo bus level.These
meters are calibrated to properly display the different internal levels within the console.
The 0VU point is the nominal operating level of whatever signal is being Solo’d. Use the
Solo system and metering to set the gain of an Input channel, monitor the output level of
a bus or check on the vocal blend of an Aux monitor mix.
Headphone Source
The operator can use the phones to listen to the various signals within the Console.The
headphones are normally fed from whatever sources are selected in the Monitor Section,
the level to the phones are controlled by the Phone Level control, the Monitor level con-
trol will not affect the headphone level.
When Solo is active, the headphones automatically switch over to the Solo bus.Any chan-
nels that are PFL’d, or any outputs that are AFL’d will be heard.The Monitor meters also
automatically switch over to the Solo bus to display the levels of any Solo’d signals.
headphone jack ( 1/4" TRS)
The headphone signal is available on this jack.The headphone driver is designed to drive
headphones of 8
Ω
or higher impedance (approx 30
Ω
is best).
phones level
This pot controls the headphone level.
Mute Scene Masters
Four independent Mute Scenes are available on the HP-Eight. Each of the Mono Input
channels can be assigned to any of the 4 scenes.When a Mute Scene is activated, any chan-
nels assigned to that Master will be muted.
Mute A
When this switch is depressed, the LED will illuminate and any channels assigned to this
Scene will mute.
Mute B thru D
Same type of operation as the Mute A switch.
NOTE : Since the Solo
system uses a summing
bus, if more than one
source is selected (PFL
switch is depressed),
the signal being dis-
played and heard is a
mixture of those select-
ed signals. When set-
ting the gain of an Input
channel, make sure that
only 1 Input is selected
to avoid errors.
+
NOTE : An Input channel
can be assigned to any
or all of the Mute
Scenes. If more than
one scene is assigned,
the Input will mute if any
of the associated
Master Mute switches
are pressed.
