INTEGRAL
Description and features
The INTEGRAL-MA is a 4-channel matrix-amplifier in 2U
rack format with built-in digital signal processor, ideal
for installations. The unit has 4 analog input channels,
8 analog output channels and 4x4 DANTE digital audio
channels. Control, configuration and management of
the unit can be executed with the ALMA software via
Ethernet or Open Sound Control (OSC) protocol. Digi-
tal audio channels can be processed and injected back
into the network.
Main features include priority assignment (two levels)
per every output, routing matrix with gains, equaliza-
tion and advanced filters for each channel, phantom
power for Mic/Line inputs, etc., making it the essential
unit or brain of any installation. The internal memory
is capable of managing more than 100 global presets
and 200 output channel presets (presets for each loud-
speaker model). A bank of presets per output channel
with specific processing and parameters for each and
every DAS Audio system is included, allowing users to
configure each channel independently and flexibly.
Two of the analog inputs can be selected as micro-
phone inputs with phantom power available.

Description and features
Additional features include a 1.54” OLED screen for
displaying input and output vumeters, equipped with
keys to navigate quickly, intuitively and easily through
the different menus. The front panel provides access to
multiple functions such as input and output muting,
output routing, input and output gain, memory recall,
channel linking, priority and phantom activation, etc…

LEDS
PROTECT: The LED indicator will light up RED when the am-
plifier enters protection mode due to overheating, short-cir-
cuit or another cause.
SIGNAL/LIMIT: The LED indicator will light up GREEN when
there is presence of signal in an output channel. If the limiter
of one of the channels is activated, it will light up RED.
COMMS: The LED will light up ORANGE when the system is
connected via OSC or ALMA to PCs or mobile devices.
ON: When the amplifier is turned on, the LED illuminates
GREEN (steadily); The light will blink GREEN when the ampli-
fier is in STANDBY mode.
1.54” OLED DISPLAY
Allows the visualization of the signal level of input channels
(both analog “A” and digital “D”), as well as the output channels
(AMP + AUX).
The display also lets you navigate through the matrix-amplifier
configuration menus and select parameters.
NAVIGATION KEYS
Four navigation and selection keys allow you to select options
and settings from the screen menus. To access a menu from
the vumeters screen, just press the right key or ENTER.

Analog Signal Inputs
Analog signal input connections use 3.5mm pitch, 5-pin “Termi-
nal Block”-type connectors. There are 4 input channels: INPUT
A, B, C and D. Channels A and B can be used as microphone
inputs activating the phantom power from the front panel.
Analog Gain Controls for Mic/Line Inputs
Gain controls for input channels A and B. They should only be
used when channels A and B are employed as microphone in-
puts.
Processed Analog Signal Outputs
These 3.5mm pitch, 5-pin “Terminal Block”-type connectors are
the outputs carrying the amplifier´s DSP processed signals.
There are 4 auxiliary processed output channels: AUX 1, AUX 2,
AUX 3 and AUX 4. These outputs can be used to send signal to
other amplifiers without processing (INTEGRAL-Axxxx models)
or to self-powered systems.
RJ45 Connectors
RJ45 connectors connected to an internal Ethernet switch that
allows daisy-chaining between units. It is recommended to use
a CAT5e cable or superior. The RJ45 ports will be used for:
• Connecting the unit to the network so it can be controlled
with ALMA / OSC
• Send/Receive DANTE digital audio

Speaker Power Outputs
Speaker Outputs use 5.08mm pitch, 4-pin “Terminal Block”-
type connectors. There are 4 amplified and processed speaker
output channels. Channels AMP 1, AMP 2, AMP 3 and AMP 4.
Channels can be bridged in pairs for high impedance lines
(100/70V). Select the AMP BRIGE mode to bridge two power
channels (AMP1-2 or AMP3-4) and directly connect the systems
in parallel with transformer (high impedance).

Analog audio connections
The MA matrix-amplifiers have 4 balanced input chan-
nels for analog audio. These are INPUT A, INPUT B, INPUT
C and INPUT D.
Channels A and B can be used for both line and micro-
phone. There are two analog gain controls on the rear pa-
nel for the two mic/line A and B inputs. Remember that
the gain controls should be used primarily when con-
necting microphones to these inputs. Phantom power
for channels A and B is available from the options menu,
which can be operated from the front panel display and
navigation keys, (it can also be activated from ALMA).
One of the main features of the INTEGRAL-MAxxxx, ma-
trix-amplifiers is that they feature 8 independent pro-
cessing channels with two assignable priority levels per
output.
Four channels are used to process the 4 amplifier chan-
nels, while the remaining channels, named AUX OUTPUT,
are used to send balanced signal to INTEGRAL-Axxxx
modules or active systems.

Analog Audio Inputs
The following illustration shows an example of a system
connection with 4 analog audio inputs: a microphone is
connected to input A, a monophonic line signal (from a
WPM1 wall mixer) is connected to input B and a stereo
line signal (from an AS2 unit) is connected to inputs C
and D.
