Introduction

Thank you for your purchase of Reflex, Lexicon's Dynamic MIDI® Reverberator.

Reflex gives you 8 world class reverberation and effects algorithms to enhance any audio performance. Sixteen preset effects provide a wide range of superb sounds right out of the box , and a bank of 128 registers is available for storing your own customized effects. — We've loaded the registers with an additional 96 sounds to really get you going!

Reflex front panel operation is straightforward, with three adjustable parameters which allow you to make subtle or dramatic changes to each preset.

An Advanced Programming Mode allows you to access additional parameters within each algorithm, providing fine control over every aspect of the effects. This mode also gives you front panel control over Utility functions such as MIDI channel assignment and register dumps.

Footswitch control allows you to bypass the effects, to step through the registers, or to set up register chains to suit your performance needs

MIDI Program Change can be used to access any register, or to bypass Reflex processing. Beyond simple Program Change, Reflex lets you change parameters in real-time, using MIDI Note Number or continuous controllers. You can create as many as 4 patches per effect, controlling Predelay with Mod Wheel, Reverb Time with MIDI Notes, etc. Dynamic MIDI™ allows exceptionally expressive performance and sequencer control.

Two of the algorithms (Chorus and Multi Taps) allow you to control echo rhythms with MIDI Clock, so you can synchronize delays to drum machines and sequencers, vary the echo repeat rate, and still maintain tempo.

1

Getting Started

Even deeper control is available through full MIDI SysEx implementation which allows bidirectional communication with a dedicated controller, such as Lexicon's MRC, or a personal computer with appropriate software. In fact, Reflex is already compatible with existing editors which will recognize it as a member of Lexicon's LXP series.

To make sure you get the most out of Reflex, be sure to read the manual.

Setting Audio Levels

1.Turn Reflex INPUTand OUTPUT controls all the way down (fully counterclockwise).

2.Connect Reflex inputs to an audio source, and Reflex outputs to an amplifier or mixer.

3.Apply an input signal at a level that you typically use.

4.While sending audio to Reflex, gradually turn up the INPUT control until the Input Status LED* lights green. Continue to advance INPUT until the LED lights red on only the loudest peaks. If the LED is continuously red, turn the INPUT control down.

5.If Reflex is using a console's sends and returns, set the MIX control fully clockwise (100% wet). If you are using an instrument amplifier, start with MIX set halfway up.

6.Gradually increase the setting of the OUTPUT control until the audio level from the amplifier or mixer is approximately the same as when Reflex is bypassed.

* The Input Status LED is off when the incoming signal is low; it lights to indicate acceptable levels

(6dB to 30dB below overload). The LED lights red when the signal approaches overload. Acceptable signals will trigger red flashes only on peaks.

Overview

Reflex front panel operation is simple and straightforward. Effect selection, editing, STORE, and CLEAR functions are easily accomplished with dedicated knobs and buttons.

Front Panel Operation

This section describes all of these basic functions, as well as using footswitches to step through registers and register chains.

7

Presets and Registers

Reflex is loaded with 16 permanent presets, designed to give you the following effects:

1LARGE HALL Lexicons’ famous hall reverb for instruments and voices requiring a “Concert Hall” environment. Experiment with different settings of DELAY (Predelay) to make the sound bounce off the back wall.

2VOCAL HALL A slightly smaller hall with added reflections to create a doubling effect with vocals.

3PIANO HALL Small and dense initial envelope which works well with the percussive nature of any piano. Changing DELAY will separate the source from the reverb, adding liveness to any recording.

4MUSIC CLUB Combines a bright, tight space with strong early reflections. Great on fast tempo music, background vocals or bright acoustic sources.

5GUITAR STAGE Small, bright music space combined with a slap reflection. Great for electric or acoustic guitars. Increase DECAY for solos. Also exceptional for drums or percussion when you require a smaller stage ambience.

6SMALL ROOM Very dense, with a smooth short decay time. Great for ADR or other types of dialog sessions. You may want to try pre-fader sends to set the source far back in the room.

7INVERSE The reverberation envelope is sharply tilted to provide a long rising attack followed by a sharp cutoff. DECAY alters the length of the effect. DELAY varies predelay.

8GATE Provides a very dense field with a sudden cutoff, rather than the smoothly decaying envelope normally associated with reverberation. DECAY varies the length of the gated effect. DELAY varies predelay. Traditionally used with drums and percusive instruments, but also effective on many other types of material.

9RICH PLATE Closely mimics the sonic traits of a metal plate. With a moderately large size, this preset gives a clear example of the sonic characteristics of the plate algorithm.

8

10 DRUM PLATE The plate sound for drums and other percussive instruments, but also very useful for a variety of broadband audio sources. Reverb time is very short and dense.

11VOCAL PLATE Designed specifically for vocals, this plate is slightly dark and very smooth. A slight predelay has been added to separate the source from the reverb envelope.

12FLANGER A straightforward stereo flange. DECAY controls the amount of feedback or resonance. DELAY varies the depth and speed of the flange.

13CHORUS The Chorus algorithm is a 6- voice stereo chorus with an interesting twist which allows for both Chorusing and Delay effects. DECAY controls recirculation. DELAY sets the delay line length. The CHORUS preset has very short DELAY and a moderate amount of diffusion.

14 CANYON A single, recirculating echo effect. Slap echoes with DELAY set to midrange area, and longer (1.5 seconds max) echoes with DELAY set in the upper range. DECAY controls the number of recirculating repeats. Creates stunning realism with the original audio signal.

15 MULTI TAPS A 4-Tap bouncing delay program with the bounce going back and forth between left and right outputs. The texture changes significantly as you vary DELAY. Great on short staccato sounds. Creates interesting blends with longer sustained sounds. Most effective when outputs are sent to a stereo return or stereo cabinet, and panned full left/ full right.

16 RESONATOR Designed to mimic the effect of resonance that occurs when holding down the damper pedal on a piano. Adds a fascinating color to any sound source.

Each of the presets contains a unique version of the 3 parameters; DECAY, DELAY and FX LVL. The parameters of each preset are available for front panel adjustment along their entire range, allowing you to create hundreds of variations of each effect. (As many as 7 additional parameters are accessible in Advanced Programming Mode or via MIDI.

Presets cannot be erased or overwritten by parameter changes; the original version will always be restored. If you make changes to a preset and want to save the changes as a custom effect, you must store your new version in one of Reflex’s 128 registers.

More Effects

Reflex is shipped from the factory with its 128 registers filled with the effects listed here. Remember that registers are volatile. When you save an effect to a register, the current contents will be overwritten. Once you've overwritten a register, it cannot be restored, even by reinitializing the unit.

We've put duplicates of the presets into the first and last 16 registers, so you can overwrite these with your own effects immediately and not worry about missing out on anything. The general organization of the effects is as follows:

10

Each of the 16 presets in Reflex consists of a unique combination of parameters. These fixed parameters determine the type of preset — hall, room, plate, etc. that you will hear when you turn the REGISTER/PRESET knob.

For each preset, several parameters have been made available for front panel control through the DECAY, DELAY and FX LVL controls.

In Halls and Rooms (1-6), and in the Plate presets (9-11), DECAY sets the nominal reverberation decay time for a predetermined room size which is unique to each preset.

In the Inverse and Gate presets (7-8), DECAY changes both the size and the character of the program, while DELAY varies the predelay before the gated effect. (Note that changing the setting of DECAY in either of these presets will briefly mute the effect.)

In the Flanger preset (12), DECAY controls flange resonance. In Chorus (13), Canyon (14), Multi Taps (15) and Resonator (16), DECAY controls recirculation.

DELAY generally sets the amount of predelay (the length of time between the input of signal and the onset of reverberation). The range of this control varies with the type of preset.

In Chorus, Canyon and Multi Taps, DELAY controls the echo delay. In Flanger, it controls the depth of the flange effect. In Resonator, it controls the delay time for the first of four equally spaced delay taps.

In each preset, FX LVL sets the level of the effects being added to the signal.

About the Parameters

Note that the setting of the MIX control is very important with several of the presets. In the Inverse and Gate presets, MIX allows you to set up anything from a subtle thickening or enhancement, to a solid wall of reverb. In the Chorus and Flanger presets, MIX should be set higher than 50% wet to get rich chorus and flange effects.

A diagram showing the parameters controlled by DECAY, DELAY and FX LVL in each preset is shown on the following page.
