4 QUICK INSTALLATION
4.1 Before you start
Before powering up the unit, make sure that the input and output XLR cables are in
good state and following the following pinning diagram: 1 for shield, 2 for live(+), 3 for
return (-) as defined by the AES14 standard.
Do not connect the unit to your computer before installing the software and the USB
Driver. Please refer to installation instructions in this manual.
When connecting the DSP to the amplifiers, mute the DSP outputs (or turn down the
amplifier’s volume knobs) until you configure your processing. Loudspeakers may be
damaged due to a wrong setup. It is advisable to unmute first the high frequency
channels: in case they are connected to low frequency drivers by mistake, they
cannot be damaged. Otherwise, high frequency speakers may be damaged because
of trying to reproduce low frequencies.
4.2 Power Up
After powering up the unit, all LEDs will be lit for about six seconds, while the
following message is displayed on the LCD:
After that, the DSP unit displays its main screen:
Now the DSP unit is ready to operate. The screen shows the name of the unit (above
line) and the program name currently active (below line). The program assigned is
always the last program the user recalled or stored before powering down the unit.
An admiration mark (!) beside the program name means that the program has been

4.3 Control Software
4.3.1 Introduction
The DSP units are shipped with a Computer Software which provides a Graphic User
Interface (GUI) application - DSPLink. DSPLink allows the user to control the DSP
unit from a computer via the USB communication link (or additionally through
Ethernet, in model DSP608). For the USB connection, a driver must be installed
(included with the DSPLink installation package).
The GUI application makes it much easier to control and monitor the device, allowing
the user to get the whole picture on one screen. Programs can be recalled and stored
from/to Computer’s hard drive, thus expanding the storage to become virtually
limitless.
DSPLink is available for PC and Mac. A USB pen drive or CD-ROM with the software
is included in the original package of the unit Check Master Audio’s website for a
latest version download (www.master-audio.com).
4.3.2 Installation for PC-Windows
Double click the installation file, depending whether you have a 32 or a 64-bit system:
Master_Audio_DSPLink_32_bit_v_10_X_X_BuildNr.msi
Master_Audio_DSPLink_64_bit_v_10_X_X_BuildNr.msi
Follow the on-screen instructions. You may be prompted to install the Microsoft
Visual Runtime libraries before finishing the installation. Click the checkbox to
proceed with this action.
NOTE: Installations under Windows 8 (or newer) require configuring Windows to
accept the installation of drivers without digital signature. Should you need support in
that, please refer to section 8.1 of this manual.
4.3.3 Installation for Mac
First unzip the provided installation file:
Master_Audio_DSPLink_v_10_X_X_BuildNr.mpkg.zip

Master Audio
DSP206-608. Version 1.2 Apr 14 9
Then select the .mkpg file with CONTROL+Click and select “Open”. Then follow the
on-screen instructions.
4.4 Connecting the device to a computer
4.4.1 USB
WARNING: Always install the software package DSPLink before connecting your unit
to the computer. See previous section for details.
After installing DSPLink, please use the provided USB cable to connect the unit to
your computer. The first time you connect a device, the system will ask you to look for
the driver. Choose the option “do not look for updates and to automatically select the
best driver”.
Run DSPLink and the unit will be automatically detected.
Click on the arrow next to the detected unit to open the window for parameter edition.
4.4.2 Ethernet (DSP608 only)
Use a standard CAT5 or CAT6 cable with RJ45 connectors (not supplied) to connect
the unit to your Local Area Network. The most convenient way is to connect it to a
router that provides automatic IP addresses (DHCP enabled), and that is sharing the
same network with the computer in which you are running DSPLink. In this case the
unit will be detected and configured automatically.
For direct connection with a computer, or through a switch not supporting DHCP, then
you can either let your computer get an automatic IP of the ZeroConfig range, or
assign a fixed IP to it:
To obtain an automatic IP in the ZeroConfig range:
1. Connect the unit to the switch or computer. The computer network card’s
settings must specify “Obtain an automatic IP” (by default)
2. DSPLink will detect the unit through its MAC address.
3. After some time (it may take a couple of minutes), the system will assign the
address and notify the message “This connection has limited or no
connectivity”.
To set a fixed IP in the ZeroConfig range:
1. Open your Network Connection settings and edit TCP/IP address
2. Set the IP in the ZeroConfig Range (169.254.0.0 – 169.254.255.255)
3. Set a Subnet Mask as 255.255.0.0.
4. Other parameters such as Gateway or DNS Servers may be left blank.
5. Connect the unit to the network where your computer is connected to.
6. DSPLink will detect the unit
4.5 System Optimization
In order to have a proper start of your system and an optimized configuration, follow
these steps by the first configuration:
1. Play a signal at the nominal level from your mixing desk, and set the input gain
of your processor to 0dB (Default Preset setting)
2. Set the crossovers that you want to use, while keeping the output gains also at
0dB.

Master Audio
DSP206-608. Version 1.2 Apr 14 10
3. With DISCONNECTED loudspeakers, turn up the volume of the power
amplifiers entirely clockwise (full volume).
4. Reduce the output gain and / or the output limiter setting to get the desired
gain, so that the amplifier is just clipping and the built-in limiters of your
processor are just limiting (Orange led blinking at the output channels).
5. Turn down the volume of the power amplifiers, connect your speakers, and
slowly increase the volume while checking the sound.
6. Check if the loudspeakers are reproducing distortion-free sound, and the
limiter LEDs are flashing or off, but not continuously on. If they are
continuously on, reduce the output gain of your processor.
7. If you cannot reach enough signal level, increase the processor's input gain or
turn up the level from your mixing desk.

Stereo 1-Way In1,In3 In2,In4 Off Off Off Off Off Off
Stereo 2-Way In1,In3 In2,In4 In1,In3 In2,In4 Off Off Off Off

The unit assigns the Input source for the corresponding outputs when each routing
mode is selected. The Stereo configuration will also activate the links between paired
channels (Out 1&2, Out 3&4, Out 5&6, Out 7&8)

can change the source afterwards if desired. It does not keep the configuration in
memory.
