SIBILANCE
The distortion caused by loud high frequency signals, such as the
"Ssss..." sounds in hinnan speech.
SHELVING
Describes an equalization action where all frequencies above or below a
particular frequency are boost or cut.
SLOPE
In a filter or equalizer, a description of the rate of boost or attenua¬
tion. Usually specified in dB/octave (6, 12, 18, and 24dB/octave slopes
are most common). The steeper the slope, the higher the "Q" in a filter.
THRESHOLD
An arbitrary signal level, above which a limiter or noise gate activates.
TRANSIENT
A sudden burst of energy in an audio signal, such as a breath blast in a
microphone, the sound of a snare drum, or a deep scratch in a record.
Transients frequently reach peak levels of 10 to 30 dB above standard
operating level, and may cause distortion or even damage to equipment.
UNITY GAIN
Output level = Input level.
VGA
Voltage Controlled Amplifier. An amplifier capable of both gain and
loss, controlled by a variable DC voltage.
WIRING, PHONE PLUG AND XLR
A stereo phone plug is wired + to the tip, - to the ring, and shield to
the sleeve. For a mono phone plug, combine - and shield, and connect both
to the sleeve.
An XLR (3 Pin) connector is wired + to pin 3, - to pin 2, and shield to
pin 1.
