Glossary
48V Power
Often called Phantom Power , this is a way of adding
voltage to a condenser microphone or active DI
(Direct Injection) box, to power the internal
preamplifier circuits without the need for batteries.
Balanced
a way of connecting equipment which ‘balances’ the
sound signal between two wires and a screen which
carries no signal. Any interference is picked up
equally by the two wires, but the signal on one wire
is out of phase with the other, and they cancel out.
DAT
Digital Audio Tape, a cassette-based digital recording
format.
PAN
abbreviation of ‘panorama’: controls levels sent to
left and right outputs respectively.
Phase
a term used to describe the relationship of two
sound signals. In-phase signals reinforce each other,
out-of-phase signals result in cancellation.
RIAA
an equalisation standard which defines the special
equalisation curves to match a preamplifier input to
record turntable cartridges.
Unbalanced
a method of audio connection which uses a single
wire and the cable screen as the signal return. This
method does not provide the noise immunity of a
balanced input (see above).
