Chapter 1: Overview
Introduction
Welcome to the MA2CHBOX.XL, DirectOuts two
channel monitor for MADI and AES signals.
The MA2CHBOX.XL can monitor any mono channel
or any stereo pair of 64 audio channels from a MADI
stream or the incoming AES signal.
An internal routing matrix provides signal routing
between all I/Os.
Interfaces:
• MADI I/O (SC optical, BNC coaxial, SFP cage)
• AES3 I/O
• Line Out (stereo)
• Headphone output (stereo)
• USB Port for transmission of serial data
(‘Serial over MADI’), remote control and
firmware updates.

Chapter 1: Overview
Applications
Providing 194 input channels and 198 output channels
the MA2CHBOX.XL can be used for monitoring and
signal distribution. Further it can act as (de-)embedder
of serial data.
Typical applications include:
• signal control of MADI signals within a signal
chain; e.g. on stage for line check.
• external monitors - the selected channel pair for
monitoring is copied to the Line out and/or AES
output feeding e.g. external monitors.
• recording with redundant systems - the
incoming MADI signal is mirrored to the other
MADI outputs feeding secondary recording
systems.
• signal distribution - all I/Os are accessed via
routing matrix which is controlled by a software
remote.
How it works
The input is selected for each output individually in
the menu. By turning the encoder knob, the desired
channel pair is accessed or the volume adjustment is
done.
The internal routing matrix is configured by a
software remote and stored in the device.

CHAPTER 4: Operation
Introduction
This chapter describes the basic operation of the
device.
Note that throughout this manual, the abbreviation FS
refers to sample rate or sample frequency. So, when
dealing with scaling factors, the following sample
rates can be written as:
• 44.1 kHz or 48 kHz = 1 FS
• 88.2 kHz or 96 kHz = 2 FS
• 176.4 kHz or 192 kHz = 4 FS
CHAPTER 4: Operation
page 28 of 80 MA2CHBOX.XL Manual - Version 1.2
CHAPTER 4: Operation
The display indicates that a working power supply
is connected to the power supply unit. Note that
an unlit display does not guarantee that the device
is free of voltage. To ensure that the device is
completely disconnected from mains voltage, the
power chord(s) must be disconnected.

CHAPTER 4: Operation
Input / Sync
Input
Four inputs are available:
• MADI - SC optical
• MADI - BNC coaxial
• MADI - SFP cage
• AES - DSUB-9 adaptor
Sync
The device is clocked according the setting specified
in the menu.
See S <x> (MENU) on page 38.
NOTE
Auto Sync - if only one signal is connected, it will be
used as clock source ignoring the sync setting.

CHAPTER 4: Operation
Display / Menu
The 7 segment display indicates the selected channel
pair, adjusted volume, level, menu settings.
The display is used in two modes:
• idle mode - volume (or channel) selection or
level metering
• menu mode - menu settings
After a short period of time without using the
encoder knob the idle mode becomes active;
i.e. the menu is left automatically and the display
switches back to
level metering or vol (or channel) selection.
NOTE
Firmware 1.3 (Q4/2014) introduces a default setting
for either channel or volume selection in idle mode see „Idle Mode“ on page 34.

CHAPTER 4: Operation
*** Monitoring of either a stereo pair or a single
mono channel.
Stereo => odd channels to left and even channels to
right.
Mono => left and right are identical.
This setting affects the indication of channels too
(see <Numbers> + Decimal points).
Using AES as input source (<AA>) will override the
setting and force to stereo temporarily.
**** After a short period of time without using the
encoder knob the idle mode is activated.
The display then indicates the input level for the left

bars of the segment display mark the values
-30dBFS, -18 dBFS and -6 dBFS.
The decimal point indicates a signal different from

CHAPTER 5: MA2CHBOX Remote
Introduction
The software application ‘MA2CHBOX Remote’
offers access to all settings of the device. Some
features are accessible exclusively via the remote
application:
• matrix channel based signal routing (M)
• adjustable channel mode for the output signal
• adjustable frame format for the output signal
@ 2 FS
• bittransparent processing of AES input signal
• configuration of serial embedder routing
• routing of MIDI over MADI data
Requirements
• OS version Windows® XP, Vista, 7, 8, 10
• DirectOut USB Serial driver installed
• Firmware version 1.5 or higher
NOTE
The driver and installation instructions are available at
www.directout.eu.
All settings are stored inside the device. Presets
can be stored and recalled for quick configuration
changes.
page 49 of 80MA2CHBOX.XL Manual - Version 1.2
CHAPTER 5: MA2CHBOX Remote
The overview informs about the input signal state and
offers access to the clock setting, signal routing and
the volume level and channel selection.
Click SETTINGS to access the settings of the
device, the serial embedder and the MADI output
format.
Click MATRIX to access the routing matrix for
individual assembling of the audio signal routing.
page 50 of 80 MA2CHBOX.XL Manual - Version 1.2
CHAPTER 5: MA2CHBOX Remote
Connecting the device
Remote control is available via two different methods:
a) Serial data via USB
b) Serial over MADI (embedded RS-232 data)
The USB Serial driver is required for method a) only.
However, it is required to have the driver installed
anyway for initial setup and as fallback once a cabling
or other issue interrupts the communication via the
MADI link.
To connect the device via USB:
• Go to ‘Command’ and ‘Select Serial COM port’
• Click Connect or use the connect button
page 51 of 80MA2CHBOX.XL Manual - Version 1.2
CHAPTER 5: MA2CHBOX Remote
Remote control via method b) needs a looped
MADI connection with the connected device(s) for
bidirectional communication and appropriate settings
of the serial embedder matrix.
See „Settings“ on page 55 for information about
the serial embedder matrix.
NOTE
In case of a communication loss via MADI link you
may reset the serial embedder matrix to regain
access via the local USB port.

MIDI over MADI means that the MIDI data is carried
by user bit of audio channel 56.
The MIDI matrix allows to distribute or route the
embedded MIDI data between the three MADI I/Os.
However, it does not embed an external MIDI signal
into a MADI stream or deembed from an incoming
MADI stream.

NOTE
The output selection ‘off’ - in both serial embedder
and MIDI matrix - means that the user bits of the
incoming MADI signals stick with the routed audio
signal.

The settings of the device and routing matrix can be
stored to a single file. The settings can be reloaded
separately from the same file. This allows to use the
settings independently from each other; e.g. you may
reload another routing setup without changing the
clock source.
