Equaliser
Equalisers are what would be referred to as tone controls on consumer equipment. Equalisers are
divided into a number of bands - 4 in this case. There is scope to adjust high and low frequencies
and two bands of middle (mid) frequencies. The high and low frequency sections are shelving
and the turnover frequency is switchable. The middle frequency sections are peaking and the
frequency of the peak (or dip) is adjustable. It is also possible to alter the Q of the mid sections with
a pot, making the Q continuously variable between two values. In-line consoles often have the
facility for the equaliser to be split such that it can be used partly in the channel path and partly in
the monitor path. The SF switches on ASP4816-HE equalisers allow the HF/LF and MID equalisers
to be independently switched into the SF signal path.
Flip
Flip allows the inputs to the signal paths to be swapped. Normally the LF path will carry the DAW
input, however, with FLIP pressed it will carry the MIC/LINE input while the DAW input will travel
through the SF path.
Foldback
Foldback is a mix that is returned to the performers in the studio in order that they can play in time
with what is already recorded. It could simply be the console stereo output although more usually
it is taken from a pair of auxiliary buses allowing a dierent mix to be created. Talkback may also
be included on the foldback outputs enabling communication with the artists.
In-line
This refers to a type of console which contains two signal paths within a channel strip. The channel
signal path is used to feed a DAW or other recording device while the monitor path is used to
carry the output of the DAW (or other recording device) through to the stereo mix bus. In-line
consoles can be more compact than split consoles or can carry more channels for a given size.
The possibility of switching signals between the two paths and of sharing facilities between the
paths makes the in-line concept a very attractive one.
