Features

Overview: The Lexicon MX300 is a stereo reverb effects processor that can be used for live sound and home recording applications. You can choose from multiple reverbs and delays, as well as other effects, all from the front panel. The unit comes with powerful MX-Edit Editor/Librarian and VST/Audio Units software and a USB interface, which allows it to function as a "hardware plug-in" that functions with the software. The MX300 fits into a single rack space.

Dual Applications: The MX300 can be used effectively in the recording studio as well as for live performances:

• Studio Applications: In the studio, the MX300's USB interface lets you integrate the functionality of a complex effects processor into your computer-based recording. The included MX-Edit Editor/Librarian software lets you create, edit, compare, save, and load reverb and effects programs for use with the MX300 on your Windows or Mac computer. The included VST and Audio Unit software allows you to use the MX300 as a "hardware plug-in" to give you access to the reverbs and effects within your software recording projects.
• Live Applications: With the MX300 in your equipment rack, you can dial in the sound you want directly from the front panel. You can choose a program by rotating the large Program knob until the selected program number appears in the Program Display. The program loads when you press the Program button. To edit a program, you can make adjustments to it with the three adjustment knobs (A, B, C). The editing parameters for each knob are user assigned.

Reverbs and Effects: There are 33 total reverbs and effects that are available, right from the front panel:

Factory and User Presets: The MX300 has 99 Factory Presets and 99 User Presets that allow you to create your own effects. The Factory Programs are combinations of the 32 built-in reverbs and effects, while the 99 User Program locations provide a place for you to store your own reverb and effects combinations. The User Programs are identical to the Factory Programs until you change them. A two-character LED display indicates which of the programs is loaded, while an LED indicates whether the program is a Factory or User preset.

Routing Options: The MX300 offers five signal routing options, which allow you to use it as two independent effects processors, or combine the reverbs and effects for more complex sounds. You can choose from the following routing options:

• Dual Mono: The left and right input signals are sent through Effect 1 and Effect 2 independently. Each signal is then routed to its respective output, completely independent from the other.
• Cascade (Series): Left and right input signals are first sent through Effects 1, then through Effects 2, and routed as a stereo signals to their respective outputs.

• Dual Stereo (Parallel): Left and right input signals are sent through both effects independently. The output signals of both Effects are then mixed together, and routed to both the outputs as a single stereo signal.

• Mono Split: Left input signal is sent through Effect 1, while the right input signal is sent through Effect 2. The output signals of both Effects are then mixed together and routed to both the outputs as a single stereo signal.
• Stereo Routing: When all you need is a single high-quality stereo effect path for the left and right channel signals, you can connect the processor in a simple stereo setup.

Parallel and Serial Connections: The MX300 can be used as both a Parallel and Serial effects processor:

• Parallel: A Parallel processor is connected by sending a copy of a signal into the effects device and the effected (or "wet") signal is returned to the mixer or amp, where it is blended together with the original unaffected (or "dry") signal. Parallel processing is typically used for reverbs, delays, and some modulated effects.
• Serial: A Serial processor is connected by sending the entire signal through the effects device and then to the amplifier or mixer. It is not blended with the unaffected signal. Serial processing is used for a compressor, de-esser, EQ, and modulated effects such as a tremolo, vibrato, and rotary.

Connections: The MX300 has the following rear panel connections:

• Footswitch: 1/4" TRS for connecting an optional 2-button footswitch (such as the Lexicon LEX-DFS) for independent bypass control of Effects 1 and Effects 2.
• MIDI: Two 5-pin MIDI DIN connections (In, Out/Thru)
• USB: Type B USB port for connecting to a computer using MX-Edit and MX300 plug-in window.
• S/PDIF: Two Coaxial Digital (RCA) jacks (In, Out); Digital In accepts 44.1kHz and 48kHz signals
• Analog Outputs: Two XLR female and two 1/4" balanced TRS
• Analog Inputs: Two XLR female and two 1/4" balanced TRS (XLR and 1/4" TRS cannot be used simultaneously)
