master section: monitoring and control
overview
The HPW is equipped with versatile monitoring, talkback, and muting sections that
allow the operator to monitor and control the various signals within the console. A
brief overview of each is presented. Each section will be described on its own, fol-
lowing a brief overview.
monitor section
The dedicated Monitor Section allows the user to listen to and view the various
signals operating within the Console. This section consists of the monitor select cir-
cuitry and dual LED meters, the Solo system, and the headphone system.
To better control the overall operation of the HPW, the user should ensure that the
signals within the console are being mixed as intended, and are operating within the
proper limits. The Monitor section allows the operator to select any of the main
mix buses (alone or in combination), and then listen to and view the levels of those
signals. A pair of TRS output jacks are provided to feed these signals to an external
amplifier/speaker system. The rear-panel jacks are controlled by the Monitor Level
pot.
solo system
Each Input and Output circuit of the console is equipped with a Solo switch. For
the Inputs, this switch is labeled PFL (Pre-Fader-Listen); for the Outputs, AFL (After-
Fader-Listen). Both types of these switches feed the associated Input or Output signal
into the console’s Solo bus. The Solo System feeds the Monitor Section and allows
the operator to listen to and view that soloed signal. The Solo bus is a summing bus
which will mix all selected signals together: if multiple Solo switches are depressed,
the user will hear that mixture. The Solo signal is displayed on the L and R Solo
Meters (shared with the Monitor Section).
headphone system
The headphone system is normally fed by the Monitor Section. The selected source
can be listened to on the headphones. If the Solo System becomes active, the head-
phones automatically switch-over to monitor the Solo bus.
talkback section
The operator can use the built-in facilities of the HPW to talk to the main, group,
or aux buses in the console. Often times, the operator will need to selectively com-
municate with a performer, or slate a performance during a recording. The talkback
section, with its own microphone input jack, can be used for this purpose.
mute scene section
The HPW provides 8 programable mute scenes. Each of the mono or stereo input
channels can be assigned to any of these scenes, allowing for selective muting control
of different groups of input channels. Different collections of voices or instruments
can be grouped together for overall muting, or different mute scenes can be con-
structed for the various sections of a performance.
output metering
Ten dedicated LED meters show the output level of whatever signal is being con-
trolled by the 100mm faders. Normally the 8 Group outputs, along with L and R are
displayed. If a fader-reverse switch is depressed, that corresponding Aux output is
displayed instead.
