203
Main
An output bus. A final point at which signals are mixed and affected before they leave the console.
Two versions of each Main are available for patching out of the system - Main and Main (Pre Tone and Talkback).
Main (Pre Tone and Talkback) can be used to avoid the possibility of broadcasting tone and talkback feeds.
Memory Isolation
Memory Isolation is a system whereby paths or individual path parameters can be protected from being updated when a
user memory is loaded.
Meter Display
Large TFT display used to display metering information.
Mic Input Headroom
Input headroom is the level in dB’s above 0dB available in the system before distortion (‘clipping’) occurs. The headroom
can be set within Brio 36’s Console Settings. A high headroom offers greater safety at the expense of slightly more noise.
Mix Minus
Mix Minus is a system that allows a comprehensive mix to be sent to multiple listeners each receiving the complete mix,
minus their own input.
O
On Air Mode
On Air mode allows certain operational functions to be activated or inhibited when the system is switched in to it.
P
Patch
A patch is a connection made between a source and a destination in the system. For example an input port may be
patched to one or more channel inputs, or a main output may be patched to one or more output ports.
Path
A generic term that refers to a DSP process in the system. A signal present at an input port must be routed to a path in
order for it to be processed and then sent back out of the system. Paths include channels, groups, auxes, mains, talkback
and monitor paths. Paths can be routed to other paths, for example a channel path can be routed to a group path and a
main path simultaneously.
PFL
Pre-Fade listen. A function to allow a signal to be heard before it has its level altered by a fader. Multiple PFL signals can
be sent to the PFL bus.
Port
A port refers to any physical audio input or output either built-in to Brio 36 or in a Hydra 2 I/O box. Ports can be of any
form of analogue or digital I/O. In the case of analogue signals, a single port relates to a single signal in the system.
Where digital signals are connected, multiple signals become available for each port. A single AES3 port provides two
signals, SDI can provide up to 16 signals (or more with Dolby E decoding) and MADI can provide up to 64 signals.
