Home Soundcraft Signature -- Lexicon Effects




The Signature 12 MTK console has a single internal Lexicon FX processor for adding audio processing or effects (FX) to your mix.



AUX3 is used to send sources to the FX processor.

The FX  RETURN strip is used to "return" the FX processor output to the console.
SIGNATURE_12_LEXICON_FX
The Signature 22 MTK has dual processors  (FX1 and FX2).



AUX4 is used to send sources to  effects processor FX1.

The FX  RETURN 1 strip is used to "return" the FX1 processor output to the console.

AUX5 is used to send sources to  effects processor FX2.

The FX  RETURN 2 strip is used to "return" the FX2 processor output to the console.
SIGNATURE_22_LEXICON_FX

Each FX processor can be set to any one of 22 different types of effect (FX TYPE),
such as reverb, delay, Chorus,
Rotary, LoFi, Tape emulation, and more.
 

These types are grouped 
roughly into two categories --  reverberation in the left column (REVERB)  or delay/modulation in the right column (DLY/MOD).
  • Turn the FX TYPE control to scroll through possible choices.
  • Press the control to select.

Each FX TYPE has two adjustable settings or PARAMeters (PARAM 1 and PARAM 2).

The tables below describe in more detail each of the available FX TYPES and their PARAMeters.



REVERB
Reverberation (or "reverb" for short) is the complex effect created by the way we perceive sound in an enclosed space.
When sound waves encounter an object or boundary, they don't just stop.
Some of the sound is absorbed by the object, but most of the sound is reflected or is diffused.
In an enclosed space, reverb is dependent on many features of that space, including the size, shape and the type of materials that line the walls.
Even with closed eyes, a listener can easily tell the difference between a cupboard, a locker room and a large auditorium.
Reverb is a natural component of the acoustic  experience, and most people feel that something is missing without it.

PARAM 2
ROOM Room produces an excellent simulation of a small room which is useful for speech applications. Room is also practical when used judiciously for fattening up high energy signals like electric guitar amp Liveliness Decay Time
PLATE The plate reverb algorithm simulates the original plate reverb effect - a large, thin sheet of metal suspended upright under tension on springs. Transducers attached to the plate transmit a signal that makes the plate vibrate, causing sounds to appear to be occurring in a large, open space. Plate reverbs are designed to be heard as part of the music, mellowing and thickening the initial sound. Plate reverbs are often used to enhance popular music, particularly percussion. Liveliness Decay Time
ROOM MOD A modulated room reverb. Modulated reverbs have can have a lushness or life in the reverberation that, while artificial, can be very pleasing. Liveliness Decay Time
PLATE MOD A modulated plate reverb. Modulated reverbs have can have a lushness or life in the reverberation that, while artificial, can be very pleasing. Liveliness Decay Time
SPRING A Spring reverb is created by a pair of piezoelectric crystals one acting as a speaker and the other acting as a microphone connected by a simple set of springs. The characteristic toing' of a spring is an important component of many classic rock and rockabilly guitar sounds. Liveliness Decay Time
GATED A gated reverb uses a threshold setting to abruptly cut off the reverberant field, producing a distinctive effect often used on pop percussion. Liveliness Decay Time
HALL&CHORUS A hall reverb combined with chorus effect to thicken up the reverberant field. Decay Time Modulation Speed
PLATE&CHORUS A plate reverb combined with chorus effect to thicken up the reverberant field. Decay Time Modulation Speed
HALL&DELAY A hall reverb combined with a delay effect. Decay Time Delay Time
PLATE&DELAY A plate reverb combined with a delay effect. Decay Time Delay Time


DLY/MOD
Delays repeat a sound a short time after it first occurs.
Delay becomes echo when the output is fed back into the input (feedback).
This turns a single repeat into a series of repeats, each a little softer  than the last.

DESCRIPTION PARAMETERS
PARAM 1
PARAM 2
SLAP (KARAOKE) Slap echo is a distinctive vocal echo effect heard in classic Rock n Roll, Rockabilly, and other 'classic' genres, hence its popularity in Karaoke! Number of Repeats Delay Time
DELAY (2 SEC) Basic delay algorithm with up to two seconds delay time. Number of Repeats Delay Time
DELAY MOD The modulated delay is enhanced by an LFO (low frequency oscillator) that produces a chorusing effect on the delay repeats. This is a great delay for guitar and instrument passages that need that "special something." Number of Repeats Delay Time
TAPE In the days before digital, tape echoes were created using a special tape recorder in which the magnetic recording tape was looped, with closely-spaced recording and playback heads. The delay effect was created by the tape moving in the space between the record and playback heads - while delay time was adjusted by changing the speed of the tape loop. Although very musical-sounding, wow and flutter combined with a significant loss of highfrequencies, and to some extent also low frequencies, are all elements commonly associated with tape echo. Number of Repeats Delay Time
LO FI Delay with limited bandwidth that degrades the signal in a pleasing way for a crunchy percussion or any where a lo-fidelity effect will enhance the feel. Number of Repeats Delay Time
STUDIO CHORUS Chorus creates a lush, full sound by combining two or more signals together where one is unaffected and the other signals vary in pitch very slightly over time. Chorus is commonly used to fatten up tracks and to add bodyto guitars without colouring the original tone. Chorus can also be used with discretion to thicken a vocal track. Modulation Speed Modulation Depth
MODERN CHORUS Dual-voice chorusing that's both very rich and very smooth. Modulation Speed Modulation Depth
TREMOLO Tremolo is obtained by smoothly modulating the amplitude (volume) of the original at a determined rate. Modulation Speed Modulation Depth
ROTARY Rotary speaker cabinets were designed to provide a majestic vibrato/choir effect for electronic theatre and church organs. This algorithm emulates the famous "Leslie" speaker with two counter-rotating elements: a high-frequency horn and a low-frequency rotor with slow and fast speeds. Modulation Speed Modulation Depth
VIBRATO Vibrato is obtained by smoothly modulating the pitch of the signal just sharp and flat of the original at a determined rate. Modulation Speed Modulation Depth
VIBRAPAN A unique dual voice vibrato effect with a variable phase control for the voices. Modulation Speed Modify/Phase Control
PHASER The Phaser automatically moves frequency notches up and down the spectrum of the signal by means of a low frequency oscillator (LFO), creating an oscillating "comb filter" type effect. This effect is very useful on keyboards(especially pad presets) and guitars. Modulation Speed Modulation Depth
