Introduction
Welcome to the MA2CHBOX.XT, D.O.TEC’s head-
phone amplifier for monitoring MADI and AES signals:
The MA2CHBOX.XT can monitor any mono channel
or any stereo pair of 64 audio channels from a MADI
stream or the incoming AES signal. The signal is fed
to the headphone and AES output in parallel. The
MA2CHBOX.XT provides the following interfaces:
• Standard MADI I/O (coaxial, BNC and optical,
SC)
• two ExpressCard I/Os for use with RME MADI-
face
• AES I/O (adaptor DSUB-9 to XLR male / female)
• USB Port for transmission of RS 232 data (virtual
serial port) and firmware updates.
• Headphone output (stereo)

Chapter 1: Overview
Applications
The MA2CHBOX.XT can be used for monitoring one
or two channels out of 258 channels (4 x 64 channels
MADI + 1 x 2 channels AES3).
Typical applications include:
• external monitors - the selected channel pair for
monitoring is copied to the AES output feeding
e.g. external digital monitors.
• recording with redundant systems - the incoming
MADI signal (main input) is mirrored to both Ex-
pressCard outputs feeding two RME MADIfaces.
• playback from an ExpressCard to the MADI
chain, thus allowing a virtual soundcheck (EC
Mode).
• signal control of MADI signals within a signal
chain; e.g. on stage for line check.
How it works
The input is selected in the menu. By turning the en-
coder knob, the desired channel pair is accessed or
the volume adjustment is done. Two modes (normal
mode / EC mode) allow different signal routing. The
USB port for RS 232 data transmission is switchable.
Thus allowing a transparent signalow through the
MA2CHBOX.XT.
