PREVENTIVE MEASURES:

FEATURES & GETTING STARTED:

INTRODUCTION

M-A2 is a compact and modular active all-in-one column system.

This installation system features of full range frequency response and stereophonic sound. It is composed of one 2×6.5”
sub, two columns and one four-channel amplifier.

M-A2 generates a clear, dynamic and balanced sound throughout the frequency range of this system. The array configura­tion ensures greater coverage with very well-balanced sound distribution even in the farthest corners of the venue.

Please read the attached safety instructions as well as the following instructions carefully.
Please keep all the instructions.
Please use the device only as intended.
Please respect the valid waste management rules. Please deliver the packaging divided into plastic and

paper / cardboard to the recycling management.

Please refer all servicing to qualified personnel only if the device is damaged, exposed to liquid / rain or if it does

not operate normally.

Please do not expose the product to any kind of heat such as ovens, radiators, or any other devices (incl. amplifiers).
Please also make sure that there is enough distance between amplifiers and walls, racks, etc. to prevent overheating.
After connection please check the wiring to prevent any kind of accident or damage.

Please never use any kind of damaged cable and wiring.

Only use approved and stable stands, brackets, shelves, tables etc.. for installations. Please check for

adequate stability to avoid a collapse.

Appearance of interferences when using wireless systems.
The simultaneous use of wireless microphones and mobile phones (if both devices are not very far away from
each other) can cause interferences in the microphone signal which can be heard in the PA system.

CAUTION:

To reduce the risk of electric shock, do not remove cover (or back). No user serviceable parts inside. Refer
servicing to qualified personnel.

The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the
user to the presence of uninsulated “dangerous voltage” within the product´s enclosure that may be
of sufficient magnitude to constitute a risk to persons.

The exclamation mark within an equilateral triangle is intended to alert the user to the presence of
important operating and maintenance (servicing) instructions in the literature accompanying the
appliance.

CAUTION! HIGH VOLUME!

You will operate this transmission system for professional use. Therefore the commercial use of this equipment
is liable to the rules and regulations of the Accident Prevention & Insurance Association of your industry sector.
as a manufacturer is bound to inform you formally about the existence of eventual sanitary risks.

This system is able to induce an acoustic pressure of 80 dB. 85 dB is by law the maximum audio pressure
level which your ear can be exposed to during a work day. It was set according to the technical expertise of the
occupational medicine as a basis for the noise rating level. Higher sound levels or longer exposition times could
damage your ear. The time of exposition by higher sound pressure levels should be shortened in order to prevent
from ear damages. Here are a few reliable warning signals which show that you have exposed yourself for a too
long period to excessive sound pressure levels:

- You hear bell- or whistling sounds!

- You have the impression that you can’t hear high tones anymore!
