DRY RECORDING – Recording a signal without applying any effects (such as
reverb) to it.
DYNAMIC RANGE – The difference, in dBs, between the noise floor of an audio
device and 3% THD (Total Harmonic Distortion). The Signal-to-Noise-Ratio
(SNR) plus the available headroom represents the dynamic range of the device.
ECHO – A discrete repetition of a sound.
EFFECT - Outboard gear used by the AUX Send/Return system. The wet signal
from the effect is returned to Ghost and combined with the dry signal.
EQUALIZATION – An intentional modification of an audio signal’s frequency
response.
EQUALIZER – A signal processing device used to change the frequency response
of the audio signal it processes.
EQUALIZER, GRAPHIC – An equalizer, generally with a series of vertical slide
controls, with each control representing a fixed centre frequency. The sliders can
boost or cut the signal, and their settings give a graphic representation of the
resulting frequency response. Ghost does not have a graphic equalizer.
EQUALIZER, PARAMETRIC – An equalizer with continuously variable controls
for the centre frequency and Q (bandwidth) and a boost/cut control. The
boost/cut control raises or attenuates the level of the selected centre frequency,
with the width of the boost/cut around the centre frequency determined by the
setting of the Q control. Ghost has two parametric equalizers for each channel,
labeled HMF and LMF.
EQUALIZER, SHELVING – An equalizer that applies a variable amount of
boost/cut at all frequencies above or below the equalizer’s fixed frequency. It con-
sists of a boost/cut knob for the fixed frequency. Ghost has two shelving equalizers
for each channel, labeled HF and LF.
EQUALIZER, SWEEPABLE – (Sometimes called semi-parametric.) An equalizer
with continuously variable controls for the centre frequency and a boost/cut con-
trol, but no Q (bandwidth) control. The boost/cut control raises or attenuates the
level of the selected centre frequency, with the width of the boost/cut around the
centre frequency being fixed. In effect, a sweepable EQ is similar to a parametric
EQ, but without the Q (bandwidth) control.
EXTERNAL TREATMENT - Using outboard gear on a signal before the signal
enters Ghost.
FADE-IN - Beginning a recording by gradually raising the level using a fader.
FADE-OUT – Ending a recording by gradually lowering the level using a fader.
FADER – A variable level control. In Ghost, there are 100mm vertical faders (slid-
ers) for the Channels, Group masters, and Main Mix master, and rotary faders
(knobs) for MIX B, MIX B master, and AUX masters.
FADER, MASTER – A single fader used to control the output level of all signals
sent to it. In Ghost there are master faders for the Group, MAIN MIX, MIX B, and
AUX outputs.
FILTER, BANDPASS – A filter designed to allow a relatively narrow band of fre-
quencies to pass through, while attenuating all frequencies outside that band. (It’s
the opposite of a Notch Filter.)
FILTER, HIGH-CUT – (Also known as Low-Pass.) A filter that passes low fre-
quencies, while attenuating those at or above a specified frequency. For instance,
if the specified frequency is 10kHz, then the filter will not affect frequencies below
10kHz and will cut all frequencies at 10kHz and above.
FILTER, LOW-CUT – (Also known as High-Pass.) A filter that passes high fre-
quencies, while attenuating those at or below a specified frequency. In Ghost, the
LOW-CUT FILTER (LCF) in the channel input section, has a specified frequency of
100Hz. This filter will not affect frequencies above 100Hz and will cut all frequen-
cies at 100Hz and below.
FILTER, NOTCH – A filter designed to attenuate a relatively narrow band of fre-
quencies. (It’s the opposite of a Bandpass Filter.)
