Pan Designators (Surround Sound)
Pan designators are used to set pan law(s) according to the format(s) of the destinations a source
is being panned across. Pan designations are created with the Desk Editor software and are part
of the Desk Setup. Mono groups and Tracks can have pan designations.
For example: Channel 1 is routed to Track 1 through Track 6. In the Desk Setup, Tracks 1-3 have
been "pan designated" as Front Left, Front centre and Front Right respectively. Tracks 4 & 5 are
designated left and right and track 6 is pan designated as mono.
When channel 1 is panned L-R, tracks 1-3 will receive a correct LCR pan - i.e. there will be no
signal on the left speaker when the pan has passed to the right of the centre speaker. At the
same time, tracks 4&5 will get a correct L-R pan with a phantom centre. Track 6 will not be
affected by the pan control at all. When channel 1 is panned front to back, tracks 1-3 will fade out
because they are designated front destinations, but channels 4-6 will not be affected (they are not
designated as either front or rear).
Path
Path (or signal path) is the term used to describe a discrete section of signal flow through the
console that has a distinct input and output, either to the outside world or to another path. For
instance, the input to a Channel is connected to an input port and the output from a channel is
connected (routed) to other signal paths (Track Monitors, Groups, etc.).
In an analogue console, there is a fixed number of signal paths and they are hard-wired into
different parts (or modules) in the console.
Libra Live can be configured with the numbers and types of paths required for a session using the
software utility "Desk Editor" that is part of the Encore suite. The paths are then assigned to
faders on the console surface using "Desk Designer". Channel, monitor, group, auxiliary and main
output paths can all be given full processing (EQ dynamics etc) if required.
The main path types are:
Channel Path: Mono or stereo - these are the main input paths for the console.
Monitor Paths: Mono only - these paths consist of a track input (which is similar to channel path
but can be switched between an input and the bus of the same number) and a track output, which
is the output of the bus with the same number. Monitor path processing can be put in either the
track input or the track output. Monitor paths are used for multitrack outputs, mix-minus and
surround sound outputs
Groups: Mono or stereo - can be used as outputs or as sub-groups feeding the main outputs
Mains: Mono or stereo main outputs.
Listens: Stereo AFL and PFL busses
Sels: Stereo monitoring selectors, e.g. Main speaker selector, Headphone selector, meter
selector etc.
Films: Surround monitoring paths
EXTs: Stereo external inputs into the monitoring selectors
TB: A mono internal path used to route talkback and oscillator.
Ports
A port is a physical I/O connection to the console. This may be a MADI connection directly to the
DSP rack, or an analogue or digital connection to one of the I/O racks. Libra Live incorporates a
router that allows any input port to be connected to any input path and any output path to be
routed to any output port.
Libra Live uses a standard naming system for ports, but users may also assign their own names
for commonly used ports. The standard format uses lower case letters for inputs and capital
letters for outputs and looks like #nnn$$$ where # is the number of the MADI port the I/O is
connected to, nnn is the type of input, e.g. aes, lin (linear=analogue), mic or mad (MADI) and $$
