Operational Problems
The MPX 1 does not transmit SysEx Automation commands.
Check the Automation setting (and the Xmit Device ID selection) in the System
mode MIDI menu.
The MPX 1 will not lock onto an incoming digital signal.
Check the cables that you are using. DO NOT USE ANALOG AUDIO CABLE TO
CONNECT DIGITAL AUDIO.
Check to make sure that your input signal complies with S/PDIF format
standards. The MPX 1 will only lock onto valid 44.1kHz signals.
The front panel knob and the < and > buttons are not performing the
expected function.
In Edit and System modes, the Value button acts as a toggle to determine
whether the knob or the < and > buttons perform the functions of selecting
displayed items, or adjusting their values.
No Effects Output
Check the setting of Mix Mode in the System mode Setup menu, the setting of
Mstr Mix and Lvl at the Mix button and the Effect Mute at the Bypass button. Also
verify that any controllers patched to Input Level, or Mix are not turned off.
The MPX 1 performs a series of self tests each time it is powered on, then
displays the MPX 1 copyright notice. This should be followed by the display and
loading of the last loaded effect. If this sequence does not occur, contact Lexicon
Customer Service.
