Delays - Lexicon MX300 User Manual

Effects Descriptions
ER Time
Adjusts the amount of time before reverb early reflections occur.
ER Level
Adjusts the level of early reflections within the reverb.
Feedback Delay
Changing this parameter changes the resonant frequencies of Plate reverb.
Feedback Level
Adjusts the Plate reverb's presence and prominence.
Boing
This is a unique parameter to the Spring reverb, designed to increase or decrease the
amount of spring rattle that is a physical characteristic of spring tank reverbs.

delays

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.
Studio Delay -
Stereo
The Studio Delay features up to 2.5 seconds of stereo delay and offers a built-in
ducker that attenuates the delay output whenever signal is present at the input. This
can be used to keep the original signal from being muddied up by delay repeats.
Mono Delay -
Mono In/Stereo Out
The Mono Delay is the cleanest, most accurate of the delay programs, with up to 5
seconds of mono delay and the built-in ducking feature.
Tape Delay -
Mono In/Stereo Out
In the days before digital, delays 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 high frequencies, and to some extent also low frequencies, are all elements
commonly associated with tape recordings. The Tape Delay offers up to 5 seconds of
mono delay.
Pong Delay -
Mono In/Stereo Out
This delay effect pans the delay repeats from left to right, while the input signal
remains at its original (center) position. Pong Delay offers up to 5 seconds of mono
delay time.

Modulated Delay -
Stereo
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." The Modulated Delay
features up to 2.5 seconds of stereo modulated delay.
Reverse Delay -
Mono In/Stereo Out
This delay effect emulates the old studio trick of flipping a tape over, playing it back-
wards through a tape delay, and recording the effect. The delays "build up" from softer
to louder – creating the sensation that the delays come before the signal. Up to 2.5
seconds of mono delay time are available.
2-Tap Delay -
Stereo
The 2-Tap Delay is probably best described as an adjustable pong delay where each
tap can be individually set in relation to the delay time. The 2 taps are a calculated
percentage of the actual delay time from 1-100% (for example, if the delay time is
500ms and Tap 1 is set to 50% and Tap 2 is set to 100%, Tap 1 time would be 250ms
and Tap 2 time would be 500ms). Narrow spacing of the tap percentages can widen
the stereo image of the delay while wider tap spacing can create rhythmic delay lines.
Delay Controls
Tempo
The actual delay time as tapped in by the Tempo button or received via a MIDI clock
source. This time can be expressed as actual time (milliseconds, seconds) or in BPM
(beats per minute) values. Tempo works in conjunction with Delay Time to set the
actual delay time that is heard.
Delay Time
Controls the length of the delay time relative to Tempo. At the middle of its range,
delay repeats are synchronous with the Tempo button (represented by a Quarter Note
in the display); lower values create faster repeats, while higher values increase the time
between repeats.
Feedback
Controls the number of delay repeats by feeding the delay output signal back into the
delay input. This creates a series of delay repeats, each slightly attenuated until they
become inaudible. Higher settings create more repeats; lower settings reduce the num-
ber of repeats. When this knob is turned fully clockwise, it engages Repeat Hold – delay
repeats play back in an infinite loop, but no further input signal is introduced into the
delay effect.
High Pass Filter
Frequencies below this level are attenuated.
Low Pass Filter
Frequencies above this level are attenuated.
