6:1 GLOSSARY OF TERMS
AC POWER INPUT Local electrical supply.
ATTENUATE To reduce a signal, or reduce gain.
AUTO-PANNER A device which automatically moves an instrument between left and right. Can be
triggered manually, or by another instrument connected to its sidechain.
AUXILIARY SEND Extra output from the console, normally used for sending a mix of various instruments
to effects or foldback systems.
BUSS This carries a signal, or sum of signals through the console eg "left" buss.
COLD The negative phase of a signal. With 2 signal wires, one is positive (hot), and the other
is negative (cold).
COMPRESSOR A device which literally compresses a signal so that its level can fit onto media which
have a narrow dynamic range. Compression is often needed before recording onto
cassette tape, and is very useful for vocals.
CONDENSER MICROPHONES High quality microphones, generally best suited to recording work. To use with
POWERHOUSE, switch on the +48V Phantom Power.
dB (DECIBEL) A logarithmic ratio used to represent voltage or power gain. The reference to which
the ratio is being made is usually stated.
DIGITAL DELAY A device which samples a piece of sound, stores it digitally, then converts it back into
sound a short time later.
DRY A signal which has not been sent to an effect (see also WET).
EFFECT A general term used to refer to an external piece of equipment which can be used to
"fix" signals which sound wrong (noise gating for example), or used creatively to
produce an "effect" (reverb for example).
EFFECTS SEND See AUXILIARY SEND
EFFECTS RETURN Any place where effects may be returned to the console for mixing; on the
POWERHOUSE consoles there are LINE inputs and STEREO RETURN which are
suitable for this purpose.
EQ (EQUALISATION) Refined tone controls. Each "band" of EQ can adjust a particular frequency to make it
more or less prominent.
FADER A slider, rather than rotary, volume control.
FEEDBACK This is normally caused by a microphone being too close to a speaker. Feedback is an
"endless loop" in which an "output" (from a speaker) gets accidentally fed back into an
"input" (microphone). This can be a deafening howl, or sometimes in headphones a
whining noise will be added to the sound.
FLAT EQ Equalisation has been set so that no frequencies have been boosted or cut - every
frequency is at the same level.
FOLDBACK A separate mix for the performers to hear consisting of live instruments, pre-recorded
backing tracks and sometimes effects returns. The MON system of the
POWERHOUSE consoles is designed for this purpose.
FREQUENCY SPECTRUM The entire range of frequencies from very low (sub-bass and bass) to very high
(treble).
