1.
INPUT
– a 3-pin female XLR audio input connector. The MLA Mini system can be fed with either
balanced analogue audio or AES3 digital audio. The same connector is used for both formats,
and the analogue/digital selection is made via VU-NET control software.
The default setting is
analogue . Please refer to page 32 for details about using the MLA Mini with digital audio.
2.
LINK
– a 3-pin male XLR connector in parallel with the INPUT XLR. This allows the audio
input to be conveniently “daisy-chained” to further MLA Mini systems.
3. OUTPUT – two Neutrik® NL8 multi-pin connectors. Use the pre-made cable supplied with
the system to connect each OUTPUT socket to two Minis. If a longer cable is required,
please refer to page 28 for assembly details and cable specifications. The diagrams on
the panel show clearly which Minis should be wired to each connector. The system will not
operate correctly if this wiring is not observed. See “Cabling, connecting up” on page 28.
4. U-NET 1 – a LEMO-pattern K Series network connector. This can be used to connect the
MSX to a computer running VU-NET control software, via a Merlin interface. This allows the
system to be tailored more precisely to suit the venue and application in situations where
a configuration other than those provided by the internal presets is required. When using
the internal presets, the U-NET connectors may be ignored. Please see page 31 for more
details.
5. U-NET 1 status – bi-colour LED indicating network status.
6. U-NET 2 – a second network port for connection to additional MLA systems. VU-NET is able
to determine the order in which cabinets are connected by analysing the inter-port latencies.

status.
8. POWER connector – a Neutrik® powerCON TRUE1 connector for AC mains input. A mating
connector is included. Pre-made power cables of various lengths are available from Martin
Audio; alternatively, If making up your own power cables, please follow the Neutrik®
assembly instructions on page 14 carefully. Please note that Neutrik tool Part No. HTAC
is NOT supplied. Tightening the connector assembly with the tool to the specified torque is
only necessary if the MSX is required to meet IP65 environmental protection conditions. If
IP65 compliance is required, please contact Martin Audio for additional information and the
necessary additional parts.
9.
POWER
LED – illuminates when AC power is applied to the MSX. Note that the MSX
electronics unit has no power switch; it is operative as soon as power is applied.
10. PRESET SELECT – this push-button selects one of the factory-designed internal presets,
optimising the MLA Mini system for a particular rigging configuration or required coverage
area. See page 23 for full details of each preset. The adjacent numeric display confirms
the currently loaded preset.
11. MINI USB – Type B USB port. Allows connection of a PC for system control and monitoring
purposes. For simple set-ups using the internal presets, this connector may be ignored.
Please refer to page 37 for more details.
