1. More Me: This term refers to personal
individual monitoring levels.
Example: When the talent tells the engineer -
I need to hear “more me”.
2. FOH: Acronym which means Front Of House -
such as FOH mixer
3. PA: Stands for Public Address such as a sound
system to make voice or music louder.
4. Perfect Mix: Used by Hear Technologies to
explain the baseline mix. You may think of it as
any of the following:
• Control Room Mix - also known to as
“two mix”
• A stereo FOH mix for the PA
• CD recording
• What you’re selling
When using conventional monitors, musicians
and singers hear direct and reflected sound
allowing them to experience spatial sound
information.
When using in-ear monitors the talent have
their ears plugged and cannot hear the impor-
tant direct and reflected ambient sounds
experienced as with stage monitors or listening
acoustically.
The “perfect mix” restores this valuable
physco-acoustic information to the performers.
We highly recommended a “perfect mix” for
every performer using in-ear systems to deliver
the spatial information experienced while
performing without in-ear or headphone
systems.
Even if you use a mono PA system, such as a
single point source cluster or simple mono PA
system, one should create a stereo FOH mix
and send it to the monitoring system as the
“perfect mix”. We feel this is the best way to
achieve a natural feel for the talent when using
in-ear systems.
5. FX/EFX: Acronyms or slang used for "effects
unit”. Reverb, delay, etc. are examples of such.
6. TRS Balanced: This refers to a connector type
that carries a balanced (plus and minus) signal
pair as well as an overall shield
7. Gain: The amount of amplification (voltage,
current or power) of an audio signal, usually
expressed in units of dB. While similar to level,
it is a more critical adjustment that insures
maximum gain is reached without distortion and
to reduce signal to noise ratio.
Glossary of Terms
8. Level: This is also referred to as volume.
9. ADAT ® : A registered trademark of the Alesis
Corporation and taken from the acronym "DAT."
ADAT (Alesis Digital Audio Tape) is the name
Alesis chose in the early 1990's for their ground-
breaking product, which records eight tracks
digitally on a standard 1/2" SVHS video cassette.
The ADAT has been arguably the most significant
technology/price breakthrough for recording
studios in the last 20 years and has undoubtedly
changed the face of modern recording forever.
The ADAT has gone through several generations
and is currently a 24-bit digital format. The ADAT
optical connections for transferring digital data
8-tracks at a time have become a standard of the
industry and used in a wide range of products
from many manufacturers.
10. dB: Equal to one-tenth of a bel, named after
Alexander Graham Bell. Since the Bel was a very
large unit, the Decibel (first used in telephony in
1929 by W. H. Martin) became the new name for
the transmission unit, where signal loss is a
logarithmic function of the cable length. This is
still very much in use today.
The dB is the preferred method and term for
representing the ratio of different audio levels.
Being a ratio, decibels have no units. Everything
is relative. Since it is relative, then it must be
relative to some 0 dB reference point.
To distinguish between reference points a suffix
letter is added as follows:
a. 0 dBu: Preferred informal abbreviation for the
official dB (0.775 V); a voltage reference
point equal to 0.775 Vrms. +4 dBu Standard
pro audio voltage reference level equal to
1.23 Vrms.
b. 0 dBV: Preferred informal abbreviation for the
official dB (1.0 V); a voltage reference point
equal to 1.0 Vrms.
c. -10 dBV: Standard voltage reference level for
consumer and some pro audio and is
typically equal to 0.316 Vrms.
d. 0 dBm: A power reference point equal to 1
milliwatt. To convert into an equivalent
voltage level one must specify impedance.
For example, 0 dBm into 600 ohms gives an
equivalent voltage level of 0.775 V, or 0 dBu
e. 0 dB SPL: A reference point for the threshold
of hearing, equal to 20 micro Pascals, rms.
f. dBA: Popular way of stating loudness measure-
ments made using an A-weighting curve.
