SAFETY RULES

• The MSX sub-bass/electronics unit must be powered exclusively by an earth connected

mains socket in an electrical network compliant to IEC 364 or similar local rules. It is

absolutely vital that the user veriﬁes this fundamental safety requirement. If you are in any

doubt, get the installation checked by qualiﬁed personnel before use.

• The means of disconnection from the mains is the mains plug. We strongly recommend that

you power the MSX from a professionally installed mains supply with an easily accessible

on/off switch or circuit breaker. A comprehensive mains distribution system with circuit

breakers is available from Martin Audio.

• Before powering the MSX via the Neutrik® PowerCON TRUE1 connector, make sure that

the unit is supplied with the correct mains operating voltage:

• 100 – 240 V, 50 – 60 Hz

• The MSX power section is protected by four fuses:

• F1, F2, F3: 3 x 3.15 A Type “T” (power ampliﬁers)

• F4: 1 x 4 A Quick blow (aux power supply)

• Do not use this unit if the electrical power cord is frayed or broken

• Do not remove the cover. Removing the cover will expose you to potentially dangerous

voltages.

• When not ﬁtted with the optional rain cowl (Martin Audio Pt No ASF15027) or not used with

mains connector/cords rated to at least IP25, the MSX must not be exposed to dripping,

or splashing and no objects ﬁlled with liquids, such as vases should be placed on the

apparatus.

MLA MINI USER GUIDE

INTRODUCTION

IMPORTANT:

This document is the User Guide for the MLA Mini Loudspeaker Array system. It is an

abridged and edited version of the MLA Mini Advanced Manual and describes how to set

up a basic MLA Mini system in its most common conﬁgurations, using the internal factory

presets.

All system owners are recommended to download and retain a copy of the MLA Mini Advanced

Manual from http://www.martinaudio-mla.com/downloads/brochuredownloads. The manual

contains additional information on alternative rigging possibilities and the assembly of

larger systems. It also contains further details of the MLA Mini’s design philosophy.

UNPACKING THE UNITS

After unpacking the units, please check them carefully for any damage. If any is found,

immediately notify the carrier concerned - you, the consignee, must instigate any claim. Please

retain all packaging in case you need to return any units.

MLA Mini User Guide V1.0 7

MLA MINI USER GUIDE

OVERVIEW

Like the MLA and MLA Compact systems from which it is derived, the MLA Mini is a precision

multi-cellular loudspeaker array designed to accurately deliver a required SPL (acoustic

loudness) within a deﬁned area. Smaller and lighter than the MLA and MLA Compact systems,

the MLA Mini will reproduce high quality sound in smaller venues, as either a ﬁxed or portable

installation.

The basic MLA Mini system consists of 4 MLA Mini full-range cabinets (referred to throughout

this User Guide simply as ‘Minis’), used in conjunction with a single MSX sub-woofer. This is

the minimum conﬁguration in which the MLA Mini system can be used. The MSX incorporates

all the power ampliﬁcation and other electronics for the 4 Minis as well as the sub-woofer. (Note

that the power ampliﬁcation and electronics may be removed from the MSX cabinet for rack

mounting elsewhere; please refer to the Advanced Manual for full details.)

Used in stereo pairs, this minimum conﬁguration will be adequate for many outdoor and indoor

venues with a capacity of up to approximately 250 people, and is the conﬁguration described in

this User Guide. Additional Minis can be added, in sets of four, to create more powerful systems.

Please refer to the Advanced Manual for more details.

MSX – REAR PANEL

All connections for a single system comprising 4 Minis plus one MSX are made to the electronics

unit mounted in the rear of the MSX cabinet.

3 45 6 7 89

2 1011

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 the Advanced Manual 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 the User Guide 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 22.

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. 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 the Advanced Manual 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.

7. U-NET 2 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 9 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 18 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 the Advanced Manual for more details.
