	MX400		Introduction

INTRodUCTIoN

Congratulations and thank you for purchasing the MX400 Dual Stereo/Surround Reverb Processor! The MX400 provides you with the legendary Lexicon reverbs and effects powered by four processors, for a wide variety of configurations and blends, all in a single rack unit. Use the MX400 live or in the studio, connect and control it via your PC or Mac, or use it as a hardware plug-in. The possibilities are virtually endless!

INCLUded ITeMS

•MX400 Dual Stereo/Surround Reverb Processor

•This owner's manual

•MX Edit/USB driver CD

•Power Cord

•Lexicon Warranty Card

Quick Start

QUICK START

Ideally, you should read this entire manual before using the MX400. But, if you just can’t wait to get started, this section explains how to set up a simple parallel connection (using the MX400 with a mixer) and select a program.

StanDarD ParaLLeL connectIon

1.Connect the mixer’s Post Fader Aux Send outputs to the MX400’s Left and Right (Front) inputs.

2.Connect the MX400 Left and Right (Front) outputs to a stereo Aux Return input on the mixer (or a stereo line input, or two adjacent line inputs if you like).

Aux

Return 1

Return 2

Send 1

Send 2

PoWerInG the unIt

1.Plug the included power cord into an A/C outlet.

2.Connect the power cord to the Power Jack connection on the MX400’s back panel and turn on the MX400's power.

Power

Set auDIo LeveLS

1.Set the gain on the mixer’s input channel appropriate to the source (vocal mic, guitar, keyboard, etc.).

2.Set the Aux Master level (if provided on your console) to the 12 o’clock position.

3.Set the Input A level on the MX400 to the 12 o’clock position.

4.Provide source signal (by speaking or singing into the mic, playing guitar, keyboard, etc.) on the selected mixer channel.

5.Turn up the Aux Send levels on the channel corresponding to the Post-fader send (Aux 1 and Aux 2 in this example) that the MX400 is connected to until the red input LEDs light only occasionally. If the red Input LEDs stay lit, too much signal is being sent to the MX400; reduce the Aux Master or Aux Send on the mixer.

6.Turn up the Aux Return 1 and 2 to the 12 o’clock position, or stereo line input faders to the 0dB position, if you used that connection.

7.To increase or decrease the amount of effect on the signal, adjust the Aux Send level on the channel that you want affected.

2. USB Port

Provides communication with a computer for use with MX-EditTM Editor/Librarian software and MX400 plug-in window using a standard USB cable. When the MX400 is connected to a computer via USB, the blue USB LED next to the main display will light.

3. Footswitch Input

The optional Lexicon® LEX-DFS 2-button footswitch can be plugged into this TRS jack for remote control of the MX400 (see page 34 for more information).

4. MIDI In, MIDI Thru

Provides MIDI operation capabilities. Two 5-pin MIDI DIN connectors are available for MIDI IN and MIDI THRU. (See page 50 for MIDI Implementation charts.)

5. S/PDIF Digital In/Out

Digital input accepts 44.1kHz / 48kHz signals. When the S/PDIF digital input is selected and active, the S/PDIF LED on the front panel lights.

Important: It is recommended that you do not connect any digital device to the MX400’s S/PDIF inputs that transmits at sample rates other than 44.1 kHz or 48 kHz (such as 96kHz). Doing so can cause unpredictable performance. Make sure the device you are connecting to the MX400’s S/PDIF In is set as the Clock Master (if that option is available) and transmitting at a sample rate of 44.1kHz or 48kHz only. As with any other connection, if you need to unplug the S/PDIF cable, it is recommended that you switch to the analog inputs (see Input Source in the System menus) or bypass both processors before disconnecting the cable.

	MX400		The Rear Panel

6. Balanced Analog Line Output Pairs

Dual RF-filtered 1/4" balanced/unbalanced TRS or balanced XLR line outputs are servo-balanced, so no signal loss is incurred when using unbalanced connections (1/4" inputs only). If only a single plug is connected to the Left output, both Left and Right signals can be summed to mono by selecting Mono Left for analog output A or B in the System Menu. Pairs are grouped and labeled as A - Front (Stereo) and

B - Rear.

7. Balanced Analog Line Input Pairs

Left and Right active analog 1/4” TRS or XLR balanced line inputs. If only a single plug is connected to the Left input, the signal can be split and sent to both the Left and Right input paths by selecting Analog Mono L for input source A or B in the System Menu. Pairs are grouped and labeled as A - Front (Stereo) and B - Rear.

About the MX400

AboUT The MX400

The MX400 is an extremely versatile effects processor; in fact it can operate like three different processors. When using the MX400, it is recommended that you decide what type of processor you need it to operate as (Surround, Stereo, or Dual Stereo processor), make the proper cable connections, and select the Configuration that coincides with your setup. Each Configuration has its own bank of factory and user programs that are designed to work best with the recommended audio connections for each Configuration (see Connecting the MX400). Since the MX400 offers multiple processor configurations, the following section is a guide to help select which Configuration is best for your needs.

CoNNeCTING The MX400

The MX400 has four inputs and four outputs grouped in pairs A - Front (Stereo) and B - Rear. There are also two S/PDIF input/output connectors (A and B) that are the digital equivalent of these analog input and output pairs.

The MX400 is the first processor in its class to provide true surround reverb processing. The surround reverb algorithm always uses both output pairs A and B (analog and S/PDIF) and can accept stereo input signals via Input Pair A (analog or S/PDIF) or true 4-channel input sources via input pair A and B (analog or S/PDIF). Input/output pair A is for use with the front stereo speakers in your surround system, while input/ output pair B is for use with the rear left and right speakers. The S/PDIF outputs A and B always mirror analog outputs A and B but input pairs A and B can only be analog or digital (selectable in the MX400’s System menu)

Stereo confIGuratIon connectIonS

Stereo Mode configures the MX400 as a single stereo input/output processor utilizing input/output pair A only (analog and S/PDIF). Input/output pair B is disabled when the Stereo configuration is selected. S/PDIF output A mirrors analog output pair A but input pair A can only be analog or digital (selectable in the MX400’s System menu).

DuaL Stereo confIGuratIon connectIonS

The MX400’s Dual Stereo configuration shows off the MX400’s true power by providing two independent stereo processors, with each processor running independent programs from the other. These processors are labeled A and B and utilize their respective analog and digital inputs and outputs (A and B) on the rear panel. The S/PDIF outputs A and B always mirror analog outputs A and B but input pairs A and B can only be analog or digital (selectable in the MX400’s System menu).

The MX400 and Digital I/O

For sources that will run through Program A (this is the program shown in the top half of the Program Display which uses Effect 1 and Effect 2), connect to the A Left/Right (Front) input and output pair. Sources running through Program B (this is the program shown in the bottom half of the Program Display which uses Effect 3 and Effect 4), connect to the B Left/Right (Rear) input and output pair.

Once you have your connections made, you should refer to the Effect/Mix Routing section of the manual for understanding how the signal sources can be routed through each configuration’s programs and effects.

The MX400 ANd dIGITAL I/o

The MX400 is equipped with two digital inputs and outputs (S/PDIF A and B). Each S/PDIF pair is the digital equivalent of analog input/output pairs A and B. The digital outputs on the MX400 are always active and will always mirror their analog output counterparts. This allows you to plug in an analog input source and have it be output as a digital stream.

The MX400 has three options for input sources which are configurable in the System Menu: Analog Mono Left, Analog Stereo and Digital. (Press the System button to access the System Menu; turn the Page/Select knob to scroll up and down the menu.)

Each input pair (A and B) can have different audio sources selected depending on your needs. While in the System Menu, use Knobs A, B, and C to change values. As with all equipment that receives digital audio streams, when setting either Input Source A or B to Digital, the MX400 can no longer use its own internal clock source for the audio

	MX400		The MX400 and Digital I/O

stream, and it is necessary to change the clock source from the MX400’s internal clock to Digital.

Furthermore, the MX400 only receives external clock sync on the S/PDIF A input. This means when using both Digital inputs (A and B), the devices that are connected must be synced to a common clock source to work properly with the MX400.

If only S/PDIF B input is to be used, the MX400 still needs the external clock source to be connected to S/PDIF A.

If the Clock Source isn’t changed to Digital when digital input sources are selected, there will be synchronization problems between the incoming digital audio stream and the MX400’s processing, and the System Input Source menu will display DIG NO LOCK. When the MX400 is properly synchronized with the incoming digital audio, the System’s Input Source menu will display DIGITAL.

The MX400 only runs at 44.1 kHz or 48 kHz sample rate (using internal or external clock sources). Do not connect external digital outputs to the MX400 that run at higher sample rates (88.2 - 192 kHz) as the MX400 cannot accept them.
