Access
On Lawo consoles, much of the source parameter operation is performed by selecting
a fader strip. This is otherwise known as putting a source ‘in access’.
Attack Time
In the context of dynamics processing (compressor, limiter, gate or expander), the
attack time defines the duration over which an input signal is measured. The longer
the attack time, the slower the processor will react. For example, when using a gate,
a fast attack time causes the gate to open quickly when signal exceeds the gate
threshold.
Aux
Auxiliary
An Aux is a general purpose mono, stereo or multi-channel summing bus which can
be used for a variety of applications such as sending to outboard effects devices.
Aux Send
Auxiliary Send
Source channels feed onto each aux via their Aux Send. The aux send from each
channel can be either pre or post fader and has variable level control.
Aux Master
Auxiliary Master
The Aux Master is a master source channel used to control the level and processing
of the Aux output. The direct output of the Aux Master is the signal routed to the
outboard effects send.
Aux Return
Auxiliary Return
The Aux Return is the name given to the return channel from the outboard effects
device. This channel controls the level and processing of the effect as it is summed
into the rest of the mix.
Band Pass Filter
See Filters.
Balance
Balance is applied to the input of a stereo channel and is the ratio between the left
and right input levels. When Balance is set to its default value, the level of left and
right inputs are equally weighted.
Bargraph
An optical display instrument in the shape of a LED bar for displaying signal level.
Clean Feed
See Mix Minus.
Compressor
A dynamics processor used to smooth out uneven signal levels. For example, when a
presenter shouts and then whispers, they are producing sound which has a wide
dynamic range; one moment it is very loud and the next very quiet. This can mean
that if we listened to this signal on our radio without compression, we would forever be
turning the level up and down! A compressor smooths the signal such very loud audio
is reduced in level and very quiet audio is increased in level. This results in smaller
dynamic range ideal for radio transmission.
Configuration
The system configuration is a file created by the Configuration Tool software. This file
is then transferred to the console’s system unit where it is then loaded every time the
console powers on. The configuration defines key elements of the system such as
sources, summing busses, signal processing, MF Key functions.
DALLIS
Lawo’s modular IO interfacing system based on 19” frames using plug-in cards for
different interfaces.
dB
deciBel
A unit of transmission giving the ratio of two powers.
The number of bels is the logarithm to the base 10 of the ratio of the two powers. One
decibel equals one tenth of a bel.
