Glossary

The following are a few words that may serve you
well while reading this manual. These aren't in depth
explanations, but should hopefully give you the basics
and a place to start.
AUX – Auxiliary – an auxiliary is anything that is
supplementary or additional to the main mix.
AFL – After Fader Listen – exactly as the name
suggests, this is a monitor signal that is taken after
the signal has passed through the fader/level control.
Balanced Connections – balanced connections
offer three conductors, carrying a ground, an in-
phase signal, and an out-of-phase signal. Once the
two signals are sent from one device to another, the
out-of-phase signal has its phase inverted and the
two signals are combined. Any interference picked
up along the way is removed through to phase
cancellation. This allows cables to be run over long
distances without collecting excessive noise on the
way.
Compressor – a Compressor reduces signals over
a user-defined threshold by a user-defined amount/
ratio.
Dynamic Processor – is any kind of processor
that dynamically – or in real time – adjusts signal
properties.
EQ – Equalizer – is a device or process that allows
users to boost or attenuate audio signals at specific
frequencies.
Expander – an expander is a type of dynamic
processor that helps to make background noise (such
as humming) inaudible by reducing low-amplitude
signals.
GEQ – Graphic Equalizer – is in essence the same
as an equalizer, but this title is reserved for equalizers
with more 'bands' than the typical EQ. While a typical
channel EQ may only allow for 3 or 4 frequencies to
be adjusted, a graphic equalizer may allow for 31
different frequencies.
HPF – High Pass Filter – a high pass filter will cut
or significantly reduce all audio signals below a
particular user-defined frequency, allowing – as the
name suggests – high frequency sounds to pass
through.
Acapela 16
High Shelf Filter – the high shelf filter will reduce
or increase all audio signals below a particular
frequency. The level at which the signal is boosted/
attenuated is determined by the user.
Limiter – work just as compressors do; however
with an input to output signal ratio permanently set
to infinity-to-1.
LPF – Low Pass Filter – a low pass filter will cut
all audio signals above a particular user-defined
frequency, allowing low frequency sounds to pass
through. This is significantly useful when using
subwoofer speakers on particular outputs.
Low Shelf Filter – the low shelf reduces or increases
the level of audio signals below a particular frequency
selected by the user. The level at which the signal is
altered is also set by the user.
Noise Gate – a noise gate is a dynamic process that
urns off or significantly attenuates the audio signal
passing through it when the signal level falls below
a user adjustable threshold.
PFL – Pre-Fader Listen – this is a form of signal
monitoring where the signal is taken prior to the level
control/fader.
TRS – Tip-Ring-Sleeve – this is the name given to
the type of audio jack/plug that can accept signals
through its tip, ring and sleeve.
Unbalanced Connections – unlike balanced
connections, unbalanced connections only have
2 conductors: one for the signal and one for the
grounding. This, unfortunately, makes them more
susceptible to noise and interference.
USB – Universal Serial Bus – this is a kind of
connector commonly used in computing. It offers
connectivity of all kinds of external peripherals,
including USB flash drives and pointing devices.
VGA – Video Graphics Adapter – these connectors
have commonly been used in computing to carry
video signals from a computer to a monitor. In the
case of the Acapela, they can carry signals from the
mixer to a suitable VGA-enabled display.
