On mc

consoles, much of the channel parameter operation is performed by
assigning a fader strip to the Central Control Section. 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 smoothes 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 AdminHD software. The file can
be exported and uploaded to the system’s cold start data where it will load
following a cold start. Or, the file can be uploaded to the system’s warm start data
where it is then loaded every time the system reboots or powers on. The
configuration defines key elements of the system such as the hardware
components, and default signal parameters.
