ABOUT THE MPX 550

Thank you for purchasing the MPX 550 Dual Channel Processor, featuring Lexicon’s proprietary Lexichip®.

The MPX 550 is a true stereo, dual-channel processor with 24-bit internal processing, analog-to-digital conversion, and digital-to-analog conversion. It offers 255 presets with classic Lexicon reverb, including Tremolo, Rotary, Chorus, Flange, Pitch, Detune, 5.5 second Delay, Echo, and Compression. Dual-channel processing creates two independent effects in Dual Stereo (Parallel), Cascade, Mono Split, and Dual Mono combinations.

A large, graphic front panel display provides at-a-glance viewing of program and system status. Programs are organized into 28 banks, with 27 for presets and 1 for user programs. The PROGRAM knob scrolls through all stored programs, or between banks for faster selection. Each program includes up to 20 adjustable parameters, which are organized into “Edit Pages" that consist of four parameters each. The Edit Pages button cycles through available Edit Pages for the selected program.

The editing process is further simplified with dedicated EDIT knobs that correspond to displayed parameters, as well as a special "Adjust" parameter for each program that facilitates quick changes to the most critical aspect of the sound. In many cases, this custom parameter controls several program parameters at once. For instance, it controls the liveness of space in many Chamber and Room programs by changing Decay, Early Reflections, and EQ simultaneously.

Tap Tempo simplifies the once-complicated process of matching the delay times and modulation rates of tempo-based programs to the music. Tempo-controlled delays and modulation rates lock to tempo. In addition, Tap Tempo can be controlled using the front panel Tap/Cancel button, audio input, a dual footswitch, or an external MIDI controller that utilizes MIDI Continuous Controller or Program Change messages.

The MPX 550 features Learn Mode, a powerful editing tool that allows MIDI patching of all parameters, as well as the Bypass and Tap/Cancel buttons. Standard Continuous Controller and Program Change messages provide complete control of these functions.

FRONT PANEL DISPLAY

1. Input Level Meters

Indicate incoming signal levels. Input level meters show a minimum when the incoming signal is more than -48dB digital full-scale. Level meters appear in inverse video when the signal approaches overload (-2dB digital full-scale). When signals are between these extremes, the level meters appear as shown above.

4 7

Input level meters show calibrated values, with 0dB indicating digital saturation. Markings on the open portion of each level meter show -6, -18, and -32dB. The meters have single-pixel precision in which each pixel represents 2dB.

S/PDIF digital input sources that have been mastered “hot” (at the maximum bit rate) will cause the input level meters to peak as if digital full-scale is

occurring. However, the unit is just receiving the maximum output from the source, which is loud enough to peak the meters. This is not a problem as long as the source audio is not distorted.

Gain reduction from the compressor is indicated by a descending bar situated between the two input level meters. It is also calibrated in 2dB increments per pixel.

2. Input/OVL Indicator

Reflects the input type in normal operation. The first letter indicates input type, which is selected with the System Mode parameter Input Source (see page 3-4).

1-6

MPX 550

Getting Started

"S" stands for stereo, "L" stands for mono left, "R" stands for mono right, and "D" stands for digital. "NoD" appears when digital input is selected, but no valid digital audio signal is present. The number after the letter indicates the sample rate (44.1 or 48kHz).

When the processor is in saturation, the letters "OVL" overwrite the input type indicator. This signals the need to reduce input levels or the value of a parameter on the verge of feedback. "OVL" does not indicate input overload.

3. Program Number

Indicates the number of the program that is loaded. When a different program is cued, its number will appear in inverse video below the program number after a period of time.

4. Program Name

Indicates the name of the selected program.

5. Bank Name

Indicates the name of the selected bank.

6. EDIT Knobs 1 to 4

Indicates the function of EDIT knobs 1 to 4.

7. Tempo

Indicates the current tempo as well as the current setting of the System Mode parameter Tempo Mode (see page 3-5) - "P" for Program, "G" for Global. If the current program is not affected by tempo, this area of the display will be blank.

8. Routing Configuration

Shows the routing configuration for the selected program (see page 4-18).

9. Messages

Displays miscellaneous information, such as MIDI activity, Bypass state, S/PDIF status, etc. When no messages are required, this area of the display will be blank (as pictured on the previous page).

CONNECTING THE UNIT

The INPUT and OUTPUT connectors on the MPX 550 are 1/4 inch Tip/Ring/Sleeve and XLR sockets. Either may be used. Connections should be made utilizing high-quality shielded cables.

The MPX 550 produces effects from either mono or stereo sources. Either input can be used for mono sources. It is recommended to use stereo outputs whenever possible. Only material with Dual Mono routing is designed for mono outputs. Use either output connector if mono output is required.

FOOTSWITCH

A footswitch connected to the rear panel FOOTSWITCH connector can be used to control front panel Tap and Bypass functions. A momentary footswitch can be wired to a Tip/Ring/Sleeve connector. A stereo Y-connector allows two identical switches to be used.

Note:

Power off the unit prior to connecting the footswitch; otherwise, Bypass functions will be enabled.

Dual-Function Footswitch

A dual-function footswitch with a set of labels to indicate Tap and Bypass functionality is available at Lexicon dealers or at www.lexicon.com.

SETTING AUDIO LEVELS

Note:

As with all audio products, it is good practice to first power on all outboard equipment, then the mixer, then the speakers.

INPUT

1. Load Program 1.

2. Set the Mix parameter to Dry (Edit Page 1, EDIT knob 4).

3. Using high-level program material, begin with a low input level and advance it slowly.

4. When audible distortion is reached or when the display clip indicators light and remain lit, lower the input level until the clip meters appear only on the highest peaks.

The Input Trim knob allows the unit to be driven by an input level within a range of +8 to +20dBu. The minimum setting (fully counterclockwise) should be optimal for +4dBu (balanced) inputs. The maximum setting (fully clockwise) should be optimal for

-10dBV (unbalanced) inputs.

OUTPUT

1. Press the front panel System button to activate System Mode. Output Level, the first System Mode parameter, will be displayed.

2. Turn EDIT knob 3 to set the Output Level parameter. Unity gain for a +4dBu input device should be -12dB.

3. Press the System button again to deactivate System Mode.

SELECTING AND LOADING PROGRAMS

When powered on, the unit will load the last program that was loaded during the previous operating session. To select another program, turn the front panel PROGRAM knob.

When the PROGRAM knob is turned clockwise, the unit will cycle forward through programs in the selected bank, then proceed to cycle forward through programs in the next bank. When turned counterclockwise, the unit will cycle backward through programs in the selected bank, then proceed to cycle backward through programs in the previous bank. When the PROGRAM knob is pushed inward and turned, the unit will cycle through program banks.

Turn the PROGRAM knob clockwise to

cycle forward through all programs.

Turn the PROGRAM knob counterclockwise to

cycle backward through all programs.

The name and number of the selected program appear on the front panel display (see page 1-6). The Load LED will light to indicate that the selected program is cued for loading. After 4 seconds, the front panel display will revert to showing the name and number of the loaded program. However, the Load LED will remain lit to indicate that the selected program is still cued for loading. The number of the cued program will appear in inverse video below the number of the currently loaded program. To load the cued program, press the front panel Load button.

The unit can be configured to automatically load programs 3/4 second after the PROGRAM knob stops turning. To do this, set the System Mode parameter Auto Load to Enabled (see page 3-7).

Press and turn the PROGRAM knob to

select a program bank.
