The signal is taken from a point in the circuit which is before the fader. | |

RIAA: | Record Industry of America Association, responsible for the long established equalisation standard |
| that is applied to the signal produced by a turntable cartridge. Due to the physical limitations of vinyl |
| reproduction the stylus produces a reasonable level high frequency signal but a much less lower level |
| low frequency. An RIAA |
| low frequencies. |
Reverberation: | The way in which sound reflects and bounces around the room after the source is removed. This |
| depends on the size and shape of the room as well as the materials such as carpets, curtains and |
| clothing that absorb certain frequencies. |
Reverb Effect: | This is a signal processor that connects to the console to artificially simulate the reverb effect. |
| Parameters such as decay time, diffusion and amount of reverb can be controlled. Typically selected |
| sounds are sent to the processor by turning up the channel |
| signal is returned to the mix through a channel where it adds to the direct (dry) signal routed from the |
| channel fader. |
RPM: | Revolutions Per Minute. The measurement of turntable speed, 33, 45 and 78 RPM. |
Sampler: | Another performance effect popular with DJs. The channel signal is sent to a digital processor that |
| samples (stores) a short duration of sound. The output is returned through a channel and replayed by |
| pressing a trigger. Many samplers provide creative effects such as repeat and reverse. The UREI |
| sampler is BPM activated. |
Scratching: | The art of rhythmically rocking a record back and forward on a turntable, to repeat a certain sound, a |
| vocal or tone, at the same time operating the |
| added over a bass heavy back beat. |
Slip mat: | A fabric turntable mat positioned under the record so that the DJ can hold it stationary ready to let go |
| for a fast start at the point cued. |
Split Cue: | A facility to listen to the cue signal in one ear while keeping the program in the other. Used for |
| matching the beat while cueing a new track. Some consoles provide a CUE/MIX fader to preview the |
| mix before going live. On the UREI 1601 series this is the |
Sub Bass: | A loudspeaker designed to reproduce only very low frequency sound, typically from around 30 to |
| 120Hz. A crossover is used to route only the low frequencies to the sub. |
Tempo: | The rhythmic beat of the music, usually referred to in BPM (Beats Per Minute). |
Turntable: | Otherwise known as a ‘record deck’ this plays vinyl discs, still the most popular source for DJ mixing. |
| It is common for the output of the cartridge to plug directly into the mixing console ‘phono’ input which |
| provides the RIAA equalisation required. The turntable usually has variable speed control so that the |
| DJ can synchronise the beat between tracks. |
VCA | Voltage Controlled Amplifier: An audio gain element whose level is controlled by a remote DC voltage |
| rather than through a fader or rotary control. VCA Cross fader functions as an audio cross fader but |
| with the audio level controlled by a DC voltage produced by the fader. This voltage can be |
| electronically filtered and is therefore able to remove the clicks, scratches and dropouts associated |
| with worn audio faders. |
XLR: | The professional standard 3 pin round connector used for microphone and other balanced |
| connections. Equipment female sockets are for inputs, male for outputs. |
