Note: Designed and manufactured in England by XTA Electronic Ltd. and MC Audio for DAS Audio
Group, S.L. The rear panel is common for all models.
1: Fan outlet: The variable speed fans suck air in through the front vents and out through the back of the
amplifier. Please see maintenance for recommendations on how to clean this and the front foam sections.
2: Channel A output Speakon socket: Normal output is on pins 1+ hot, 1- cold. Channel B's output is also
wired to this socket to enable a single NL4 to provide both channels and to facilitate easier wiring in bridged
mode. Channel B is wired pins 2+ hot, 2- cold. Similarly channel C's output Speakon socket carries Channel
D's output. Check the table on the rear panel for details.
3: Input XLR sockets: Connect signal inputs to these sockets, wired pin 2 hot, 3 cold, 1 ground. For
sensitivity and impedance of these inputs, please see the specifications on page 43. Inputs C & D may also
be switched to AES digital inputs, each carrying a stereo AES stream – channels A&B on socket C, channels
C & D on socket D. This arrangement allows an analogue stereo source to remain connected to sockets A &
B for fallback purposes. To select AES inputs please see the section on page 24
.
4: Auxiliary output XLR sockets: These carry the four additional channels of separate DSP processing – they
are NOT just link outputs or a copy of the power amplifier channel's processed audio – they are fully
independent.
5: Audio network connections: Four additional inputs are available via the Dante network card included. This
will also add four network audio outputs, which can be chosen (in banks of four) from a variety of processing
points within the amplifier's DSP structure. For more on this feature see the block diagram on page 13 and
set-up information from page 27.
6: Ethernet control port: Your amplifier may be remotely controlled by connecting it to a computer via this
standard Ethernet port connection. Please see the section starting on page 35 for how to use this feature.
HINT: You can quickly check the amplifier's IP address by pressing ENTER + NEXT.
7: GPIO Port: Your amplifier has a pair of general purpose logic level input and outputs that can be
configured to recall memories, put the amplifier in standby, mute and control levels, and also provide
feedback about status. Please see the section on page 36 for more details.
8: RS485 Port: Your amplifier may also be controlled via an RS485 connection, and this port may also be
used to relay control data from the Ethernet port or the front panel USB port to connect to further devices.
Please see the remote control section on page 36 for more information.
MAINTENANCE
These maintenance instructions are for use by qualified personnel only. Before any routine maintenance,
please ensure that your amplifier is disconnected from the mains supply!
The filter behind the air intake apertures on the front of your amplifier should be cleaned or replaced
periodically, e.g. 12-24 months. (Filters in amplifiers located in more 'dirty' atmospheres may require more
frequent maintenance).
The filter should be 'dry' cleaned, using a vacuum cleaner preferably. Running the unit without a filter is
not recommended unless it is within a 'clean room'. Replacement filter material is available.
If the fan vents on the rear of the amplifier develop a build-up of dust/debris on the finger guards, they
can be cleaned with a dry paintbrush and a vacuum cleaner.
The casework of the amplifier may be cleaned with a lightly dampened cloth – do not use any solvents
as they will damage the paint finish and could remove printing.
If you have any doubts about carrying out maintenance, please refer to a service engineer or contact
your local dealer.
