Introduction
The DX0.6 is a digital audio processor with an extremely
low noise floor, high dynamic range and powerful internal
DSP. It delivers excellent performance in meeting rooms,
small theaters and clubs.
The DX0.6 uses powerful custom Digital Signal
Processing and an original DSP algorithm. The DSP and
AD/DA run at 96KHz sampling rate. The DX0.6 offers
a complete processing and crossover solution for any
loudspeaker system. We have two models in this range,
the DX0.4 with four outputs and the DX0.6 with six
outputs. The number of outputs is is the only difference
between these two models.
The comprehensive signal chain features input gain,
delay, noise gate, EQ and routing, to output gain, delay,
polarity, cross-over, EQ, Program and Peak limiters. There
are a remarkable 14 types of parametric equalizer (PEQ).
The output crossover filter includes the classic Linkwitz-
Riley, Bessel and Butterworth filter styles with slopes from
6dB/octave up to 48dB/octave.
The newly designed limiter section maintains a maximum
level over a slow time constant to restrict the long-
term power applied to your speakers. This reduces the
possibility of damage and also allows for the short term
peaks that are an essential component of any program
material. A second limiter restricts short term peaks to
a safe level for the speakers thus providing the best
possible solution to keep your sound system working
faultlessly.
Each output offers the option to import a maximum 512-
taps FIR filter. Used for speaker presets, it can improve
the phase response and control the directivity according
to your requirements.

Getting started
There are two ways to set up your DX0.6. You can:
▪Use a desktop app running on a computer connected
to your DX0.6. This allows you to access all of the
settings and is usually the easiest and best way to set
up your processor. You can also use this to control your
processor remotely.
▪Use the buttons and screen on your DX0.6. This allows
you to do a quick update to your settings without the
need to connect a computer. You can access most but
not all of the settings.
You could use a combination of these
methods. For example, you could set
up the DX0.6 initially using the desktop
app. Then later you could update
settings using the buttons and screen on
the DX0.6.
Desktop app
The desktop app is a Windows app available as a free
download from the Martin Audio website.
We don't support macOS, but some
users have run this app successfully
on a virtual platform such as Parallels
Desktop, VMware Fusion or Apple Boot
Camp Assistant.
To set up your DX0.6 using this desktop app, you need
to install the app and connect your processor to your
computer.
To install the desktop app
1. Go to the Martin Audio website and select Support >
Software.
2. Select and download the DX0.4 and DX0.6 Control
Software.
3. Follow the instructions bundled with the software.
Connecting your processor and
computer
There are four ways of connecting your processor to your
computer:
▪USB. Use a USB cable to connect the USB-B port on
the front panel of your processor and a USB port on
your computer.
You can only connect one processor
at a time with USB.
▪Ethernet direct. Use a network cable to connect the
Ethernet socket on the back panel of your processor
directly with the Ethernet socket on your computer.
You can only connect one processor
at a time with a direct Ethernet
connection.
▪Ethernet network. Use a network cable to connect the
Ethernet socket on the back panel on your unit to the
same Ethernet network as your computer.
You can set up and control as
many processors as you like with an
Ethernet network.
▪RS-485. Use an RS-485 cable to connect the RS-485
socket on the back panel of your unit and your
computer. Very few PCs have an RS-485 socket, so
you will almost certainly need an RS-485 RJ45 to USB
adaptor. These are readily available and inexpensive.
RS-485 networks are highly robust and the cable runs
between devices can be up to 1,200 meters. If you
have several units, you can daisy chain them using the
two RS-485 ports on the back panel of each unit.
You can set up and control up to 32
processors with RS-485.
DX0.6 User Guide

Dynamic or static IP
With an Ethernet network, you can choose dynamic or
static IP:
▪With dynamic IP a DHCP Server allocates IP Addresses
for all devices on the network. For up to about five
processors, we recommend dynamic IP. A Wi-Fi router
is a good option for small systems, as the router will
include a DHCP Server and you could connect your
computer to the router using Wi-Fi.
▪With static IP you need to specify the IP of each
device manually. Static IP is particularly useful for large
systems with many processors.
To select dynamic or static IP, use the desktop
app (page 6). You can't change this at the front panel
of the processor.
Setting up using the front panel
To set up your DX0.6 using the buttons and screen on the
front panel, you need to:
▪Configure the main settings using the Utility menu. For
details, see Utility menu (page 10).
▪Configure the input channels. For details, see Input
channels (page 21).
▪Configure the output channels. For details, see Output
channels (page 25).
Connecting your system
For example system configurations, see Example systems
(page 30).
1. Before you connect your equipment, make sure that
everything is switched off and the master volume,
level or gain controls are all the way down.
2. Connect the line-level outputs from your mixing
console (or other signal source) to the inputs of your
DX0.6.
3. If you're using amplifiers, connect the outputs from
your DX0.6 to the inputs of your amplifiers. Connect
the outputs from your amplifiers to the inputs of your
passive loudspeakers.
If you're using powered loudspeakers, connect the
outputs from your DX0.6 to the inputs of your
speakers.
4. Turn on the mixing console (or other signal source).
5. Turn on your DX0.6.
6. Configure the system setup to match your
loudspeaker system. See Getting started (page 6).
7. Un-mute the appropriate outputs on your DX0.6.
8. Turn on your amplifiers or powered loudspeakers.
Turn up the volume or gain control. In most
circumstances, you should turn the gain controls up
to maximum so that the amplifier gain matches the
limiter threshold levels of the the DX0.6.
9. Start the signal source and raise the mixer’s main
L/R faders up until you can hear audio through the
loudspeakers.
Remember
▪When you shut down your equipment, turn off the
amplifiers first. This is to prevent thumps and other
noises generated by upstream equipment from coming
out of the speakers.
▪When powering up your equipment, turn on the
amplifiers last.
▪Don't listen to loud music for prolonged periods.

Back panel
1. Power. To turn the unit on, plug it in and press this
switch to "I". To turn it off, press this switch to "O".
When the unit is on, the LCD display on the front
panel lights up.
This unit remembers any setting changes, so when
you switch the unit on, the unit restarts with the same
settings as when you switched it off.
The unit uses relays on the outputs to prevent
unwanted pops and noise in the system when you
switch it on and off. When you switch it on, the unit
initializes and the relays switch. Any live outputs will
smoothly fade from silence to the configured output
levels.
2. Power lead socket. This IEC input is where you plug
in the detachable power cable supplied with your
processor. Plug the other end into an AC outlet. If the
cable has the wrong mains plug, either use a safety
approved IEC cable with the correct plug or ask a
qualified electrician to change the plug. Note that
the power cable has live, neutral and earth (ground)
connected.
Don't disconnect the earth
connection. This could be
dangerous.
The processor can accept voltages from 100V to
240V AC at frequencies of 50 to 60Hz. You don't need
to adjust anything on the unit.
3. Ethernet. The Ethernet port is a standard RJ45 port.
This allows you to connect to an Ethernet network
with dynamic or static IP. For details, see Connecting
your processor and computer (page 6).
As with most Ethernet ports, there are two LEDs that
show the connection state and the network activity.
4. RS485. The upper RJ45 port (labelled IN) allows
you to connect to an RS485 network. If you have
several processors, you can use the lower RJ45 port
(labelled OUT) to “daisy-chain” the units. For details,
see Connecting your processor and computer (page
6).
The connection uses pins 1 and 2 which are colour
coded Orange/white and Orange on standard Cat5e
cable.
5. XLR Outputs. The six male XLR connectors provide
an impedance balanced line-level signal for each of
the output channels. Connect cables between these
connectors and the inputs of your power amplifiers or
powered loudspeakers.
Pin 2 is + or “hot”, pin 3 is – or “cold” and pin 1
is ground. Connections to unbalanced sources should
have signal to pin 2 and ground to pins 1 and 3.
For example connection set ups, see Example
systems (page 30).
6. XLR Inputs. The two female XLR connectors accept a
balanced line-level input from a mixer or other source.
Pin 2 is + or “hot”, pin 3 is – or “cold” and pin 1 is
ground. Connections from unbalanced sources should
have signal to pin 2 and ground to pins 1 and 3.
For example connection set ups, see Example
systems (page 30).

This setting allows you to choose whether the front panel
output meters display the absolute output level or the pre-
limiter level. For details of the output meters, see Front
panel (page 8).
▪Absolute output level is the default. This is shown in
dBu
▪Pre-limiter level is the level before limit. This is shown
in dB
When you use pre-limiter level the dBu
labels on the front panel are no longer
relevant.
Pre-limiter level allows you to see at a glance how much
system headroom is available. This is particularly useful
for signals like the HF drive to a 2 or 3-way system. The
output level is likely to be relatively low so the meters will
give you very little information. The limiter threshold is
also likely to be relatively low as most HF devices have a
low power rating. So setting the meter to pre-limiter will
show you a much clearer indication of the drive to HF
components and how close your signal is to activating the
limiter.
To set the output vu-meter
1. Log in as an Admin or Expert. For details, see Security
utilities (page 20).
You can only edit this setting if you
are logged in as an Admin or Expert.
2. Press PM3 to display the Utility Menu.

After Process. Then press PM1.
6. Press PM2 to return to the System Utilities menu.
7. If you've finished, press PM2 twice to exit the menu
system.
Firmware version
This allows you to see the current firmware version. FP
is the front panel firmware and MB is the motherboard
firmware. You only need to take note of the MB version
number (if we change FP we always update MB). If you
view the firmware version in the Desktop app (page 6),
this shows you the MB version number.
To see the latest firmware version available, go to the
Martin Audio website and select Support > Software. This
shows the MB version number.
To download the latest firmware, go to the same location
and choose DX0.4 and DX0.6 Control Software. The
firmware is bundled with the software.
To install the latest firmware, follow the instructions
bundled with the software.
