Program Descriptions SINGLE PROGRAMS PLATE Plate reverb began with a large, thin sheet of metal suspended upright under tension on springs. Transducers attached to the plate transmitted a signal that made the plate vibrate, causing sounds broadcast through it to appear to be occurring in a large, open space. The Plate programs synthesize the sound of metal plates with high initial diffusion and a relatively bright, colored sound.
Program Descriptions MPX 550 GATE/INV Gate/Inv Programs "Adjust" Tap Gated reverbs were created by feeding a reverb, such as a metal plate, through an analog gate device. Decay time was set to instant, while hold time varied duration and sound.
Program Descriptions Lexicon HALL Hall Programs "Adjust" Tap Lexicon’s Hall programs recreate the acoustics of actual places - from grand, reverberant enclosures to small concert halls. 20 Small Hall (MidRT) – 21 Medium Hall (MidRT) – The clean reverberation of Hall programs is designed to add spaciousness without altering source material. In addition to general instrumental and vocal applications, the Hall programs give separately recorded tracks a sense of belonging to the same performance.
Program Descriptions MPX 550 CHAMBER Chamber Programs "Adjust" Tap Historically, recording studio chambers were oddly shaped rooms with a loudspeaker and set of microphones to collect ambience in various parts of the room. 30 Brick Wall (HighCut) – 31 Basement (HighCut) – 32 LiveConcert (Livenes) Eko Delay 33 Drum Chamber (MidRT) – 34 Moves on . . .
Program Descriptions Lexicon AMBIENCE Ambience Programs "Adjust" Tap Ambience adds warmth, spaciousness, and depth to a performance without coloring its direct sound. It is commonly used to add a room sound to recorded music and speech. In music recording, Ambience can realistically add distance to close-mic’ed signals.
Program Descriptions MPX 550 ROOM Room Programs "Adjust" Tap Room programs simulate actual rooms where there is a strong sense of being in a small, live place. These programs are useful on drums and percussion, and can also be applied to electric guitar tracks.
Program Descriptions TREMOLO Tremolo is a rhythmic change in loudness, commonly employed as an expressive technique by vocalists and wind instrument players. It is also one of the oldest effects, frequently used with electric guitar, electric piano, and occasionally vocals. Different tremolo effects are largely determined by the rate (fast or slow) and waveform shape (smooth or sharp) of the change in loudness.
Program Descriptions MPX 550 ROTARY Rotary speaker cabinets were designed to provide a majestic vibrato/choir effect for electronic theater and church organs. The most well-known rotary speaker is the Leslie™ Model 122, which has two counter-rotating elements: a high-frequency horn and a low-frequency drum with slow and fast speeds. The sound generated as the spinning elements change speed is truly magical. The swirling, spacious effect is difficult to describe - but immediately recognizable.
Program Descriptions Lexicon CHORUS Chorus Programs "Adjust" Tap Chorus effects create lush, full sounds by multiplying the original audio source. Traditionally, these effects were used to fatten up tracks and to add body to guitar without coloring the original tone. Chorus effects are also often combined with plates, echoes, and other reverb effects.
Program Descriptions MPX 550 FLANGE Flange Programs "Adjust" Tap Flange effects were originally created by simultaneously playing back identical programs on two tape recorders, then using hand pressure against the flange of the tape reels to slow down first one machine, then the other. The result was a series of changing phase cancellations and reinforcements, with characteristic swishing, tunneling, and fading sounds.
Program Descriptions Lexicon DETUNE Detune Programs "Adjust" Tap Detune effects create delayed and pitch-shifted versions of the original source, thickening the sound. This creates a particularly effective simulation of double-tracking. These effects are also great alternatives to Chorus effects, adding the richness of a chorus without the audible sweep caused by the chorus rate.
Program Descriptions MPX 550 PITCH Pitch Programs "Adjust" Tap Altering the pitch of a sound produces a wide range of effects - from subtle detuning, to harmonies, to chords. The stereo polyphonic Pitch programs can be used to shift program material or monophonic sources within a range of one octave up to two octaves down. 85 Pch Chrmatic (Pitch) – 86 Pitch Fine (Pitch) – 87 Pch 4th-5ths (Pitch) – For pitch correction, set the Mix parameter to Wet.
Program Descriptions DLY/EKO Delays and echoes repeat a sound a short time after it first occurs. The simplest (and oldest) delay effect is tape slap - a single repeat about 100ms after the original sound. Tape slap was often used on Elvis Presley’s voice and rockabilly guitar tracks. Tape slap becomes tape echo when the output of the tape is fed back into the input (feedback). This turns a single repeat into a series of repeats, each a little softer and a little darker than the last.
Program Descriptions MPX 550 In all delay programs and dual programs, the unit uses the MstrDly parameter to scale delay times that are not controlled by Tempo. In some programs, the "Adjust" parameter controls MstrDly. MstrDly can be set within a range of 0 to 100%. It is usually set to 100% in most presets. When MstrDly is set manually (or by the "Adjust" parameter) to less than 100%, individual delay times will scale accordingly.

Program Descriptions MPX 550 STEREO STAGE Stereo Stage provides stereo reverb while preserving the dry signal. To use this program, note the following: • Use the MPX 550 in line between the mixer and house amplifiers - not as an effect mixed back into the main left and right channels on the mixer. • Pan the input channels on the mixer fully to each musician’s side of the stage. • Keep the Mix parameter set to 50% (the default Program Load Mode setting).
Program Descriptions Lexicon DUAL PROGRAMS • MSplit Dly, MSplit Rvb These banks contain programs that are arranged in Mono Split configuration, which is similar to the Dual Stereo (Parallel) configuration. One effect (e.g. Flange) receives signals from the left input and the other effect (e.g. Delay) receives signals from the right input. However, both effects send signals to the left and right outputs.
Program Descriptions MPX 550 EFX BAL The Efx Bal parameter controls the relative balance of each effect in the dual programs. In Cascade variations, the parameter also varies the amount of the first effect or dry signal fed into the second effect. The illustration below uses the Pch-Dly program to show the effect of the Efx Bal parameter at certain settings when a Cascade variation is selected. 50:50%: Provides delayed pitch shift. Pitch 75:25%: Provides pitch shift, plus delayed pitch shift.

Program Descriptions MPX 550 CMPRSSR Comprssr Programs "Adjust" Tap In all Cmprssr programs, the "Adjust" parameter controls gain within a range of 0 to 9.5dB. It can be used to match volume levels between the dry, bypassed, and compressed output obtained with typical music material.
Program Descriptions DYNAMICS Note: A few seconds after the Dynamics preset is loaded, the Dynamics name will flash briefly on the front panel display. This does not affect audio input or output. Dynamics is intended for use in the studio, when dynamic processing of stereo signals is required. Because of its long delay, this preset is not recommended for use in a live performance or as a mix insert. It includes effects that perform peak expansion, compression, and tape saturation in that order.
Program Descriptions MPX 550 Meters (GR, In) Selects between gain reduction (GR) and input level (In) metering. (See page 4-35 for more information.) Thresh (-31 to -0dB) Designates the compression threshold, the level the sound source must rise above before compression is applied. COMPRESSION Compression is used to lower the overall level of sound sources that rise above an adjustable compression threshold. Compression can be used to match the levels of louder sources to those of quieter sources.
Program Descriptions Lexicon TAPE SATURATION Saturation Tape saturation emulates the sound of sources recorded on analog tapes and sources recorded digitally. Because of the natural peak saturation that occurs with analog tapes, sound sources recorded on them seem louder than the same sound sources recorded digitally. To use this effect, increase the Gain parameter setting. The amount of gain used is guided by both the output level meter and, more importantly, the ear.
Program Descriptions MPX 550 2. Peak Expansion Meter 4. Input Meter When the Meters parameter is set to In, indicates the maximum left or right channel input levels, whichever is greater. The associated tick marks are placed in 3dB increments. The right-most tick mark indicates 0dB or maximum input level. Indicates the level of peaks above the peak expansion threshold. Low-level peaks are shown as one or two graduated bars. Slightly higher peaks of longer duration are shown as three graduated bars.
Program Descriptions Typical Mastering Dynamics Control Adjustment (continued) will cause the peak expansion meter to show three solid bars for short periods of time. Increase the ExpLvl parameter until the peaks in the source material sound slightly exaggerated. Then, reduce the setting until the peaks sound natural. • • Set the Ratio parameter to 4.00:1, the Attack parameter to 7.2msec, and the Release parameter to 1.4sec.
Program Descriptions MPX 550 • • In the delay programs, two delay level controls have been combined into the "Adjust" parameter: (Tap/ Dly). These programs contain two delays. The first is controlled by tempo and generally used to create longer delays and echoes. The second is set manually with the Delay parameter, and can be used to create a "slap" of 60 to 135ms.

Parameter Descriptions Lexicon PARAMETER GRAPHICS The MPX 550 features graphic enhancements for each parameter, which appear on the front panel display whenever a parameter setting is changed. These graphics illustrate the point at which the selected setting falls within the entire parameter range, and provide a visual indication of the parameter’s function. As the setting changes, the graphic also changes to reflect the new setting. Examples are shown below and on the following page.
MPX 550 Parameter Descriptions When the Mix parameter setting is changed, the graphics pictured below appear. When a delay parameter setting is changed, the graphics pictured below appear. When the Level parameter setting is changed, the graphics pictured below appear. When the Width parameter setting is changed, the graphics pictured below appear.
Parameter Descriptions Lexicon PARAMETER GLOSSARY Balance In Rotary programs, determines the volume balance between the horn and drum. Note: System Mode parameters are described in Section 3. Dynamics parameters are described on pages 4-32 to 4-35. These parameters are not included in this glossary. "Adjust" (0 to 127) Functions differently from preset to preset. "Adjust" is a "magic" control that can manipulate several parameters at once or provide a set of special values for a single control.
Parameter Descriptions MPX 550 CmpRels (4 to 250msec) Controls the rate at which the compressor relaxes when compressed input signal levels fall. Decay (73ms to 19.61sec or 24ms to 6.53sec) Controls reverb time for mid frequency signals. In Ambience programs, Decay controls the length of the ambience "tail". Depth Appears in Dual programs where one effect is Dly/Eko, providing independent control over the Dly/Eko high-frequency output.
Parameter Descriptions DlyTapLvl Lexicon (off, -48 to 0dB) Appears in dual programs where one effect is Delay/Echo and one or more delay voice is controlled by Tap. DlyTapLvl controls the level of the Tap-controlled voice that is mixed into the Delay/Echo effect. Drum Dep (-100 to +100%) In Rotary programs, determines the amount of resonance, i.e. signal, fed back into the effect. Duration (100:0% to 0:100%) Controls the relative amounts of the two effects in Dual programs.
Parameter Descriptions MPX 550 HighSlope and LowSlope (-16 to +15) Determine the shape of the reverb envelope for low frequencies. HighSlope and LowSlope are found only in the Gate/Inv programs. When LowSlope is set to 0, the level of low reverb remains unchanged over its duration, then cuts off abruptly. Setting LowSlope above 0 causes the level of low-frequency reverb to rise smoothly from soft to loud until the sound is cut off.
Parameter Descriptions Mix Lexicon (Dry, 1 to 99%, Wet) Mix controls the ratio of unprocessed (Dry) and processed (Wet) signal in the output. When the MPX 550 is patched into a console, this parameter should almost always be set to Wet. MstrRate (0 to 100%) In Rotary programs, serves as a master rate control affecting both the horn and drum rates. Pch Fbk (L), (R) (-100% to +100%) Controls the amount of feedback through the Pitch presets, resulting in repeated echoes with pitch progressing up or down.
Parameter Descriptions MPX 550 R Dly 1, 2, 3 (0ms to 5.060sec) Sets the delay time of right voice 1, 2, or 3. The Dly/Eko effect has three independent voices on each side. Rate RvbLvl (off, -48dB to 0dB) In Ambience programs, controls the amount of "extra" longer-decay reverb added to the effect. In Ambience, short-decay early reflections create a real-room sound. (0 to 50.05Hz) Controls modulation speeds.
Parameter Descriptions Speed Lexicon (0 to 5000) In Flange programs, controls how rapidly the two "flange" voices move. Speed 1, 2 (0 to 5000) In Chorus programs, control the rates at which the various voices sweep through frequency. Spread (0 to 255) Controls the timing between the initial reflections that most audibly create the sound of a real room. Shape and Spread work together; if either is set to 0, the other has no effect.
Parameter Descriptions MPX 550 Wavform (See Below) In Tremolo programs, determines volume modulation. Settings are defined as follows: Setting Description Sine Smooth modulation with polarity reversal. Rectified Sine Smooth modulation with no polarity reversal. Triangle Linear ramp up and down. Sawtooth Linear ramp up with sudden reduction. Square Level modulates between maximum and minimum. Width (0 to 100%) Determines the effective separation between the left and right channels.
