INTRODUCTION

The AC systems is a portable active sound system (composed by a modular line
array plus a subwoofer) that combines quality of sound and design with high

operating efciency of power amplier.

Modularity is the keyword of this innovative system, designed for one-man band,
small band to big orchestra, home and movie theaters, churches... here 2 different

congurations which can be adapted to all your needs giving unparalleled exibility

whatever the application: from small to large audience!

AC System 1

features four 4.0” full range custom transducers (AC1) in the line
array satellite and one 2x10” subwoofer (AC102);

AC System 2

features eight 4.0” full range custom (AC1) in the line array satellite
and one 2x10” subwoofer (AC102);

AC Systems include high power class-D ampliers, the AC102 subwoofer features

a two-way amplier with DSP controlled crossover (500W for low channel +
500W for high channel).

The processing of the AC DSP allows to deliver a high output from these small
systems with a precise and focused response on both low and high frequencies
and a quick control of distorsion.

AC Systems design offers a perfect listening experience to the audience with its
accurate sound.
The installation is easy and simple and the different mounting setup options are
available to suit every taste and need of the listener.
The innovative design of the satellites allows to angle them for best setting as for
each type of application.

SUBWOOFER CONTROL PANEL – AC102

CLIP SUB (1) and HIGH (2)

The clip LEDs allow you to set the optimal level of the signal sent to the system’s speakers.

To nd the optimal level back off the power amp level (MASTER) so that the LEDs rarely

turn on.

GAIN INSTRUMENT (3)

This knob regulates the gain level of the INSTRUMENT input.

INSTRUMENT CLIP (4)

This clip LED allows you to set the optimal gain level of your signal due to instrument
input.

PRESETS (5)

This selector allows you to choose between 6 different equalization settings, optimized
for the use with the different systems:

AC System 1 (1)
AC System 1 with Boost (2)
AC System 2 (3)
AC System 2 with Boost (4)
AC 360° (5)
AC 360° x2 (6);

MONO/STEREO SWITCH (6)

When a stereo signal is connected to the AUX Input and you’d use two Markaudio system

in STEREO conguration selecting this switch on Stereo mode allows to send one of the

two channel of the stereo signal to the second system via XLR LINK. Select the switch in
MONO in case of only one Markaudio System or if you’d link two systems in MONO mode.

MASTER LEVEL (7)

This is the MASTER Volume level.

ON (8)

Power status indicator LED.

INPUT XLR (9)

XLR Balanced Input. The XLR 3-pole female jack is electronically balanced (hot pole:
#2). You can use unbalanced sources only if your cables have pole 3 jumpered to pole

1. Important: when powering up, turn on your sound source (CD player and mixer, for
example) before turning on the MarkAudio cabinets. When powering off, turn the cabinets
off rst.

GROUND LIFT (10)

This switch may be needed for the cancellation of hum due to ground loops with other
apparatuses;

LINK XLR/LEFT (11)

Line out to connect another Markaudio system to the principal system; it performs as a
LINK (MONO mode) or it sends only the LEFT CHANNEL (STEREO mode) when a stereo
signal is connected to the AUX INPUT.

INPUT INSTRUMENT (12)

Line input 1/4” jack (for direct plugging a MONO instrument).

AUX INPUT (13)

Line input jack for plugging a STEREO audio signal through mini-jack connector.

COOLING (14)

Forced ventilation stabilizes the working temperature of electronic components for
continuous performance, even after a long period of operation.
Avoid using the loudspeaker on irregular surfaces that might block the vents.

AC POWER SOCKET (15)

VDE power jack for connecting the power cable from the unit to a wall power source.
Make sure the unit is grounded; all three terminals of the AC power plug must be connected
to avoid any injury to the user or damage to the unit.
Markaudio powered speakers and amps are manufactured to be used in the country
where they have been sold, and are factory preset to that country’s voltage. So make
sure you’re sending the correct voltage to your amp before you connect it to AC power.

CONNECTIONS AC systems

AudioChain is composed by different modules, each one called AC1.
AC system 1 is composed by 4 AC1, AC system 2 is composed by 8 AC1.

Each module ts to another one and can be locked, after ruling the angle you

prefer, by a couple of wing screws (cockerels).

AC1

1. Put the AC102 on the oor vertically or

horizontally;

2. Screw the rod of the AC /
SPEAKER POLE on the AC102 and
insert the “top plate pole mount”
on the top;

3. Fix 4 AC1 (linked between them with
wing screws) to the “top plate pole
mount” with other 2 screw wings;

4. Take 2 (AC system 1) or 6 (AC system 2)

‘short’ jack cables and link AC1 modules

as shown in the table;

WARNING: before to remove
them from the last module
(which not connect two
modules) do not screw
completely the last screw
wings because you risk to
damage the mechanical
guides;

6. Put 2 jack caps to the rst and

the last AC1;

7. Use the “Velcro band” to link
long cables;

8. Link the power cord and turn on
your system.
