REAR PANEL

The back panel is where all connections are made and user-installable modular I/O options may be installed. The

internal auto-switching power supply provides both 110 and 220 volt operation. For installation instructions of any

optional I/O modules please refer to

MX-2424 Installation

[53]

Analog to Digital/Digital to Analog Module

The A/D/D/A module provides 24 channels of analog to digital and digital to analog conversion at 24 bit 44.1k/48k

or 12 channels of 24 bit 96k on six DB-25 connectors. All converters used are the same to ensure consistent high

quality audio across the entire machine.

[52]

Digital I/O Options

There are three different 24 track digital options for the MX-2424: TDIF, ADAT Optical, and AES/EBU. The

AES/EBU module supports input sample rate conversion.

[55]

AES/EBU Connectors

AES/EBU Female Connector:

This connector allows the input of AES/EBU stereo digital audio, which can then be routed to any odd/even pair of

tracks. Sample rate conversion may be applied to audio coming in on this connector.

AES/EBU digital clock may be received by the MX-2424 on this input as needed.

AES/EBU Male Connector:

This connector will output stereo AES/EBU digital audio and clock from a selectable stereo pair of adjacent

odd/even tracks. The default setting is clock only.

[54]

S/PDIF Connectors

S/PDIF Coaxial Input Connector:

This connector allows the input of S/PDIF stereo digital audio, which can then be routed to any odd/even pair of

tracks. Sample rate conversion may be applied to audio coming in on this connector.

S/PDIF digital clock may be received by the MX-2424 this input as needed.

S/PDIF Coaxial Output Connector:

This connector will output stereo S/PDIF digital audio and clock from a selectable stereo pair of adjacent odd/even

tracks. The default setting is clock only.

[58]

Remote Connector

This connector is used to connect the RC-2424 remote control unit. (Do not confuse this connector with the TL-Bus

connectors!)

[56}

Footswitch

This connector allows the use of a foot switch for Record Punch In/Out. The MX-2424 will sense the polarity of the

footswitch when the unit is powered on with the footswitch connected. (Do not hold down the footswitch during

power up as this will cause the MX-2424 to incorrectly sense the polarity.) See

MX-2424 Installation

for details on

supported types of footswitches.

This connector will also accept input from an Alesis LRC for basic transport control.
