software and MX300 plug-in window using a standard USB cable. When the MX300 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 MX300 (see page 33 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 44 for the MIDI Implementation chart.)
5. S/PDIF Digital In/Out
Digital input accepts 44.1kHz / 48kHz signals. When the S/PDIF digital input is select-
ed 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
MX300'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 MX300'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 press the
Program Bypass button before disconnecting the cable.
6. Balanced Analog Line Output Pair
Dual RF-filtered 1/4" balanced/unbalanced TRS and 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 Anlg Mono L in the System
Menu.
