 User Guide 

DJ

  Disc Jockey.  The console operator sequencing 

and playing the music tracks.  Some simply play the 
tracks, others talk over with introductions and 
announcements, and others provide an entertaining 
performance by mixing and shaping sounds to 
create a completely different musical experience. 

Drum Machine

   An electronic drum simulator as 

used by keyboard players and in electronic music.  
This now provides another DJ tool to create an 
alternative beat to mix in with the music. 

Dynamic Range

   The difference expressed in dB 

between the highest and lowest signal levels 
possible.  This is limited by the clipping level and 
residual noise floor respectively. 

Earth

   Also known as ‘ground’.  The term for the 

electronic signal reference.  This connects to the 
mains supply earth point and all cable shields and 
conductive equipment cases.  It provides the return 
for the signal voltage within the equipment.  It also 
ensures operator safety by removing the possibility 
of electric shock should the mains voltage touch any 
metal part. 

Earth Loop

   The result when the equipment sees 

more than one path to the system earth.  Current 
flows because a resistive loop susceptible to radio 
and mains interference is formed.  This can result in 
audible hum or buzz in the system. 

Equaliser

  (EQ)  This provides cut or boost of 

selected frequencies (equalisation) for tonal shaping 
of the sound.  This is similar to the bass and treble 
controls of domestic hifi amplifiers.  However, 

XONE

 

provides 4 independently controllable frequency 
bands for corrective or effective sound shaping. 

Feedback

   Also known as ‘howlround’ or ‘ringing’ 

this is the rapidly increasing tone produced when a 
microphone picks up its own signal from the 
speakers.  It is usually a shrill and annoying squeal 
that should be quickly dealt with by reducing mic 
gain or equalising the system to notch out the 
offending frequencies. 

Gain

   This is the boost or attenuation applied to the 

source signal in the channel preamp stage to match 
it to the console operating level.  For example, a 
large amount of gain is need to match low 
microphone signals.  It is set using the console 
meters.  Gain is not used for level (volume) control. 

Headroom

   The amount of level available 

expressed in dB to handle peaks above the normal 
0dB operating level. 

Hz

  Hertz.  The measurement of frequency.  The 

audio spectrum ranges from a low (bass) frequency 
of 20Hz to a high (treble) 20kHz.  Not many sound 
systems reproduce the full range.  Average hearing 
does not extend much beyond 15kHz or so.  
Response is further impaired if the ear is subjected 
to continual high sound pressure levels. 

Highpass

   A filter that attenuates frequencies 

below the cut-off frequency. 

Hum

   Apart from not knowing the words… this is 

the audible noise that usually results from mains 
interference pickup, earth loops, bad 
interconnections and induced power supply and 
lighting fields.  It is usually at mains frequency 
(50/60Hz) or a related harmonic. 

Impedance

  (Z)  A technical term for the resistance 

of a signal conductor to ground.  Low impedance 
usually refers to microphones of 200 ohms or less, 
and line signals typically less than 100 ohms.  Low 
Z sources are less prone to interference pickup.  
Inputs are usually high impedance so that one 
source can connect to more than one channel 
without signal loss.  Note that the operating 
impedance of a connection is set by the impedance 
of the source, not that of the unconnected input. 

Impedance balanced

   Refers to the type of output 

signal connection.  Has three conductors, two for 
signal and a shield which is connected to earth.  
Provides interference rejection similar to a fully 
balanced connection because the two signal 
conductors are matched at the same impedance.  
However, the drive capability is less because the 
signal is carried by only one conductor.  

LFO   

Low Frequency Oscillator.  Oscillator used as 

a cyclic modulation source.

 

Limiter

   A signal processor that limits the maximum 

level possible by preventing the signal going over a 
predetermined threshold level.  This is very useful in 
club installations where it is inserted between the 
console and house system amplifiers to prevent the 
DJ exceeding the maximum allowable volume. 

Lowpass

   A filter that attenuates frequencies 

above the cut-off frequency. 

MC

  Master of Ceremonies.  The presenter who 

introduces the performances and maintains the 
running order. 

MIDI   

Musical Instrument Digital Interface.  A 

protocol designed in the early 1980’s to enable 
electronic instruments to communicate.

 

MiniDisc

   A type of low cost digital 2-track recorder 

that uses a disc similar to but smaller than that used 
by computers.  It records up to 74 minutes of stereo 
material and is regarded as the modern 
replacement for the audio cassette recorder.  It has 
the added facility to label and edit tracks. 

Mono

   The left and right stereo signals summed 

together as one. 

Mute

   To turn off the signal. 

Noise

   Generic term for an unwanted signal.  This 

may be residual electronic hiss, hum, buzz, clicks 
and pops, or simply loud undesirable music. 

Noise Floor

   This is the term for the residual 

electronic noise produced by all powered audio 
equipment.  It usually sounds like a constant hiss, 
although some equipment may suffer from residual 
hum as well.
