Glossary
AFL (After Fader Listen) —A term used for the
solo function of the Groups on your RM800. The
term after fader indicates that the selected solo signal
is sourced after the faders and thus includes the level
setting of that fader. As a result, you will hear nothing
if a fader is set to minimum. See also PFL and Solo.
Bus —In an audio mixer, a common conductor used
to collect and distribute signals. RM800 has the fol­
lowing buses: GROUP 1-8, AUX 1-4, MON/AUX
5-6, STEREO, and PEL/AFL.
Clipping —Clipping means that a given signal starts
distorting, which is usually due to an excessive gain
or level setting.
Confidence monitoring —Monitoring directly
from a recording medium to make sure that program
material is being recorded correctly. On an analog
tape recorder, signals are picked up by the playback
head immediately after being recorded to tape by the
record head. This allows for confidence monitoring.
It is not possible on a tape recorder with combined
record and play heads. A DAT must have 4 heads
(inside one drum) for confidence monitoring.
Cue —A term used to describe the signal a musician
hears in his headphones while recording. The ‘cues’
are, of course, the signals already recorded or coming
from synthesizers, modules, etc. controlled by a syn­
chronized sequencer.
Cue mix —The cue mix is the mix (i.e. the balance)
of all signals sent to the headphones. Depending on
the musician, the balance of the available signals
needs to be changed (i.e. more kick for a bass player,
more HiHat and snare for the rhythm guitarist, etc.).
Dynamic range —^The difference between the
loudest and quietest signal levels in a system. In an
audio device, usually the difference between the
maximum output level and the residual noise floor.
EQ- Short for equalizer. An equalizer consists of a
series of level controls that allow you to reduce or
increase the level of a set (or selectable) frequency
range, as opposed to general level controls (such as
the channel faders) that set the volume of all fre­
quency ranges. On a lot of mixers, the high and low
frequencies that can be boosted or cut are fixed, while,
the middle frequencies to be boosted or cut are
selectable.
Foldback — See Cue Mix.
Group —A Group on a mixing console is a bus and
level control or fader to which you can assign several
channels (using the 1-2,3-4,5-6, and 7-8 switches),
so that the level of all signals assigned to a Group can
be modified with one fader. Working with Groups
allows you to increase (or reduce) the level of an
entire drum kit without modifying the balance of the
individual channel faders.
Headphone mix — See Cue Mix.
In-Line Mixer — A mixing console consisting of
two layers: one fitted with EQ and extensive effect
send facilities, while the second layer is a type of line
mixer with basic control functions (level, pan, one
effect send).
LED (Light Emitting Diode) —An electronic
component that lights up when an electric current is
applied. RM800 PEAK and SIGNAL indicators are
LEDs.
MIDI —An acronym for Musical Instrument Digital
Interface. An internationally agreed standard that
allows electronic musical instruments to communi­
cate with each other.
Monitor mix—In most situations, the monitor
mix is the same as the Cue mix. The term is actually
used to signify the signal balance that is heard in the
control room (i.e. the room where the RM800 is
being operated).
Nominal level —Nominal literally means ‘as is’.
Applied to audio, it means that the level of the
received signal is neither raised nor reduced. Setting
a channel fader to ‘O’, for example, means that the sig­
nal level equals the value set with the GAIN control
(and PAD switch).
Pan —Short {or panorama. In audio, this term is
used to signify the position of a signal between the
left and right speakers (or channels).
Patchbay —Usually a 19” multiple connection box
that allows you to use short cables (usually jack-^jack
or mini-jack->mini-jack) to establish connections
between inputs and outputs without changing the
connections on the receiving and transmitting
devices. The outputs of one device (e.g. the GROUP
OUTs of your RM800) and inputs of the receiving
