MTX-416 - PROGRAMMABLE 4x16 INTERCOM MATRIX
1. INTRODUCTION
Congratulations on your purchase of the ALTAIR intercom matrix MTX-416. There is a lot the
characteristics that make of the ALTAIR MTX-416 series one of the most highlighted in the audio
professional market, some are enumerated here:
The new Altair MTX-416 is a programmable Intercom Matrix allowing instant recall of up to 5
different presets. Each preset determines the allocation of up to 16 intercom lines into the 4 available
intercom channels.
The Matrix operates in vertical and exclusive mode, so any intercom equipment connected to line 1
for example can be addressed exclusively to one of the 4 channels.
Power to the lines is taken from the 4 intercom channels and distributed to the selected lines.
The design incorporates input and output link connectors for easy X and Y expansion of number of
channels and/or lines. An 8 channels to 32 lines matrix system can be done with 4 units.
The use of a Matrix in any medium to large size intercom system allows for daily instant
reorganization of the full intercom functionality and the ability for easy reconfiguration by the system
administrator.
The unit can also be used as an 4 in to 16 out Audio matrix and by using the reverse mode, it can be
operated as a 16 in to 4 out matrix-selector operating in horizontal exclusive mode.
Before beginning it is important to read this manual. This manual will help you to install and use
your new intercom matrix. It is very important to read it carefully, mainly the paragraphs marked as
NOTE, PRECAUTION and DANGER, for your security.
Save the original packing, you can re-use it to transport the unit. NEVER SHIP THE ALTAIR MTX-
416 WITHOUT ITS ORIGINAL PACKING.

SYSTEM EXPANSION
The connection of up to four units ALTAIR MTX-416 allows to make matrix with up to 4
channels, 64 lines, increasing the line number, or up to 16 channels and 16 lines, increasing the
number of channels, with all the intermediate situations.
Altogether we can link four units, if we want to increase the line number, we will link the units
by means of the EXPANSION-Y connector and if we want to increase the
number of channels, we will link the units by means of
the EXPANSION-X connector.
If we want that the memory change works simultaneously in all the units, or to control all the
units from a computer via USB, will connect the SERIAL OUT output of the
first unit (by means of a 8 pin RJ45 cable without inverting) to SERIAL IN
input of the second, SERIAL OUT output of the second to SERIAL IN input of third… and SERIAL OUT
output of the last one to SERIAL IN input of first. In the following diagrams, are show the different

ALTAIR MTX-416 units. The cable is connected to the computer and
anyone of the four units. With the control software, the USB driver for
the computer is enclosed.
5. OPERATION
The new Altair MTX-416 is a programmable Intercom Matrix allowing instant recall of up to 5
different presets. Each preset determines the allocation of up to 16 intercom lines into the 4 available
intercom channels.
The Matrix operates in vertical and exclusive mode, so any intercom equipment connected to
line 1 for example can be addressed exclusively to one of the 4 channels.
Power to the lines is taken from the 4 intercom channels and distributed to the selected lines.
The design incorporates input and output link connectors for easy X and Y expansion of number
of channels and/or lines. An 8 channels to 32 lines matrix system can be done with 4 units.
The use of a Matrix in any medium to large size intercom system allows for daily instant
reorganization of the full intercom functionality and the ability for easy reconfiguration by the system
administrator.
The unit can also be used as a 4 in to 16 out Audio matrix and by using the reverse mode, it can
be operated as a 16 in to 4 out matrix-selector operating in horizontal exclusive mode.

MTX-416 - PROGRAMMABLE 4x16 INTERCOM MATRIX
DISPLAY
Display allows us to know as ALTAIR MTX-416 is
configured with a simple browse. In normal mode (4x16
matrix), it will indicate to us with a LED lighting in each line,
the channel to which is connected this line (NULL if it is not
connected to any channel). In reverse mode (16x4 matrix),
will be lighting a LED by each channel, indicating to witch line is connected this channel, or turned
off, if this channel is not connected to any line.
Also display will indicate to us the different action types that the unit hopes of the user,
guiding the user at every moment to the keys that must press.
NAVIGATION SWITCHES: UP, DOWN, LEFT, RIGHT AND ENTER:
The navigation switches allow to move by the different lines and channels of
the ALTAIR MTX-416 unit. Also ENTER switch, allows to confirm diverse functions,
which will be explained more ahead.
The first switch pulsation (UP, DOWN, LEFT, RIGHT or ENTER), does that the unit
enter in edition mode. If it is the first time that enters in edition mode since the unit is turned on, it
will be positioned in the line 1, whose LED will begin to blink (in REVERSE mode, will be positioned in
channel 1, whose LED will begin to blink), if it has entered in edition mode previously, will be
positioned in the last line to which access has been had (in REVERSE mode, will position in the last
channel to which access has been had)
In edition mode, we have a cursor (LED blinking), with which we can be moved with the
navigation switches, selecting each line to that channel we want to connect it (in REVERSE mode,
we will select each channel to that line we want to connect it).
If we waited for a time without doing anything, the edition mode will be reset, and the LED
will let blink. If we pressed a switch that is not of navigation, the edition mode will be reset and the
LED will let blink. In order to change the line configuration (or the channel configuration in REVERSE
mode), we must validate it with the ENTER switch, that is to say, we move with the switches UP,
DOWN, LEFT and RIGHT and validate the configuration with the ENTER switch.
In edition mode, if we pressed the UP switch, on the selected line, the channel number will
decrease (it is looped, once it arrive to CH1 it pass to NULL), in REVERSE mode, acts in the same
mode, decreasing the channel number, but does not exist the NULL position and it will be
positioned on the line to which the selected channel is connected.
When the DOWN switch is pressed, on the selected line, will increase the channel number (it
is looped, once it arrive to NULL it pass to CH1), in REVERSE mode, acts in the same mode,
increasing the channel number, but does not exist the NULL position and it will be positioned on
the line to which the selected channel is connected.
In edition mode, if we pressed the RIGHT switch, it will increase the line number (it is looped,
once it arrive to line 16 it pass to line 1), positioning itself on the channel to which this line is
connected. In REVERSE mode acts in the same mode, increasing the line number (it is looped, once
it arrive to line 16 it pass to line 1).
DIRECT MEMORY RECALL SWITCHES (M1-M5)
The ALTAIR MTX-416 unit has five memories for the normal mode and
five memories for the REVERSE mode, plus a working memory (one for the
NORMAL mode and other the REVERSE mode), that is the one that is active
in the unit.

15
MTX-416 - PROGRAMMABLE 4x16 INTERCOM MATRIX
One of the five LED associated to the switches, remains lighting, indicating the memory in
which it is located the unit. If the working memory and the stored memory are the same, the LED
will remain without blinking, and if the working memory and the stored memory are different, the
LED will be blinking.
By means of these five keys it is possible to be acceded of direct mode to the five stored
memories, always considering that when recovering a stored memory, the working memory will
be lost.
Mediante estas cinco teclas se puede acceder de manera directa a las cinco memorias
almacenadas, siempre teniendo en cuenta que al recobrar una memoria guardada, la memoria
de trabajo se perderá.
It exists a memories bank for the NORMAL mode and other for the REVERSE mode, reason
why five memories for each mode can be recorded.
When acceding to a determined memory, if the system were linked with other MTX-416 units,
they will change all the connected units, to the memory number to which we have acceded.
MEMORY STORE SWITCH
The store switch allows us to record the working memory on anyone of the five
memories (M1-M5) available in the system.
When pressing the STORE switch, display will indicate
M1-5 blinking, the five leds of the direct memory recall
switches will begin to blink, as well as the LED
corresponding to the STORE switch, being indicated that we
are in recording mode.
The unit reset the recording mode if we do nothing or press a switch other than STORE, M1 —
M5, in a few seconds.
If we pressed one of the direct memory recall switches (M1-M5), the working memory will be
recorded in the memory number corresponding to the pressed key.
When the memory is recorded, the unit change to the memory number on which we have
recorded the working memory, reason why if the system were linked with other MTX-416 units, all
the connected units will change to the memory number on which the working memory has been
recorded.
MEMORY PREVIEW SWITCH
With this PREVIEW switch we can see the memories recorded directly in display
When pressing the PREVIEW switch, display will indicate M1-5 blinking, the five leds
of the direct memory recall switches will begin to blink, as
well as the LED corresponding to the PREVIEW switch, being
indicated that we are in preview mode.
The unit reset the preview mode if we do nothing or
press a switch other than STORE, M1 — M5, in a few
seconds.
If we pressed one of the direct memory recall switches (M1-M5), the corresponding memory
will appear in the display blinking, as well as it will continue blinking the PREVIEW switch. Passed a
few seconds, the system will return to normal mode.

16
MTX-416 - PROGRAMMABLE 4x16 INTERCOM MATRIX
MEMORY CLEAR SWITCH
By means of the memory CLEAR switch, we can reset the working memory, so that in
normal mode, all the lines are disconnected of the channels, and in reverse mode all the
channels are disconnected of the lines.
When pressing the memory CLEAR switch, the display
will indicate YES? blinking, as well as the LED corresponding to
the CLEAR switch, indicating that we are in memory clear
mode.
The unit reset the memory clear mode if we do nothing or press a switch other than ENTER, in
a few seconds.
If we pressed the ENTER switch, the working memory will erase, disconnecting all the lines of
the channels in normal mode, or all the channels of the lines in reverse mode.
REVERSE MODE SWITCH
When pressing this REVERSE mode switch, we can change the working mode, 4 IN x 16
OUT in NORMAL mode or 16 IN x 4 OUT in REVERSE mode.
In format 4 IN x 16 OUT, each one of the sixteen lines
(OUT) can be connected to one of the four channels (IN).
In format 16 IN x 4 OUT, each one of the four channels
(OUT) can be connected to one of the sixteen lines (IN).
When pressing the REVERSE switch, the display will indicate YES? blinking, as well as the LED
corresponding to the REVERSE switch, indicating that we are in reverse mode change.
The unit reset the reverse mode change if we do nothing or press a switch other than ENTER,
in a few seconds.
If we pressed the ENTER switch, we will change the mode: If we were in NORMAL mode we
will turn to REVERSE mode and vice versa.
In REVERSE mode, the REVERSE LED will remain turned on, indicating to us that the unit is
configured in REVERSE mode.
6. OPTIONS
In this section we will explain the different available options for the intercom matrix ALTAIR
MTX-416.
SECURITY COVER (TP-1)
In some installation, it may be necessary to tamper proof the front panel controls avoiding
unwanted or accidental manipulations. For this purpose, it is available as an option, a transparent
plastic security cover. The installation is very easy, only with two provided screws.
7. SPECIAL OPERATIONS
In order to set-up some of the intercom matrix possibilities, the unit must be opened removing
the eight screws of the unit top cover
NOTE: This type of operations takes place with the unit is opened; the best thing should be to carry it
out by a qualified technician.

17
MTX-416 - PROGRAMMABLE 4x16 INTERCOM MATRIX
DANGER: Before opening the unit, disconnect it from the mains. It is important to indicate that
although the unit is switched off (with the power switch in 0 position), if it keeps being connected to
the mains there are different parts of the unit that are subjected to high voltage.
CAUTION: Protect the intercom matrix from the rain and moisture, mostly if it is open. If liquid is
spilled into the unit, disconnect it from the mains and consult a qualified service technician.
OPENING THE INTERCOM CHANNEL TERMINAL IMPEDANCE
The intercom channels should have a
terminal impedance to make the different units
connected to them work correctly, however only
one can connect a terminal impedance for
channel because if they are connected two in
parallel, the impedance would diminish in a half;
for this and in order to connect other units with a
terminal impedance, it is possible to open the terminal impedance placed in each of the channels
of the unit (NOTE: Keep in mind that with all the units of the ALTAIR E-200 intercom system of ALTAIR
it is necessary to open the terminal impedance).
In order to open the intercom channel terminal impedance the MTX-416 provide some
jumpers (JP1 for the channel 1, JP3 for the channel 2, JP5 for the channel 3 and JP6 for the channel
4) placed at the left part of the main PCB, near the rear panel looking at the unit from the front
panel. With the jumper placed, the terminal impedance will be connected and with the jumper
removed, it will be open.
CAUTION: Never leave the intercom channel without terminal impedance, because a bad
operation of the units connected to the line would take place.
NOTE: The factory setting is with the terminal impedance jumper disconnected.
POWER THE CHANNELS 3 AND 4 BY THE CHANNELS 1 AND 2
Intercom channels 1 and 2 can power
intercom channels 3 and 4, by means of two
jumpers located inside the unit. The power is take
out directly of the intercom line connected to
channel 1 and/or 3, reason why must refer to the
manual of the units connected to the intercom
channels 1 and 2 for the specifications of power
and current.
With the jumper JP2 placed, the intercom channel CH3 will be powered by means of the
intercom channel CH1, with the jumper removed, the intercom channel of CH3 will not be powered
through intercom channel CH1.
With the jumper JP4 placed, the intercom channel CH4 will be powered by means of the
intercom channel CH2, with the jumper removed, the intercom channel of CH4 will not be
powered through intercom channel CH2.
The jumpers are placed at the left part of the main PCB, near the rear panel looking at the unit
from the front panel.
NOTE: The factory setting is with the power jumpers disconnected.

9. APPLICATION EXAMPLE
In the following schematic drawing an application example is represented, summarize of most
of the situations in which it can be.
It is a system with four intercom lines, formed by two ALTAIR EF-200 units.
The different units (ES-200, EM-201, 4W2-200, WBS-200), are connected to the intercom lines by
means of the ALTAIR MTX-416 matrix, reason why we have an open and flexible system, being able
to control remotely, by means of matrix MTX-416 the configuration of the intercom lines in real time.
If we added a computer control, a remote user, could control the matrix configuration, that is to
say, the intercom lines, even being possible a configuration change due to an external control signal
at the system, as can be the activation of a fire alarm.
It is then tried to make flexible the intercom lines configuration, so that the configuration in real
time can be changed.
