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.

3. WORKING PRECAUTIONS
The manufacturer is not responsible of any damage that can possibly happen to the unit outside
the limits of the warranty or those produced by not taking care with the working precautions.
Mains voltage must be between the limits of the admitted power supply (90-264 VAC, 50-60 Hz)
and that the fuse must be the appropriate (2A slow blow type: T2A). Damage caused by connection
to improper AC voltage is not covered by any warranty.
DANGER: Inside the unit there are high voltages, do not open it. The unit does not
contain elements that could be repaired by the user. Whenever the unit is connected to
the mains, it carries elements with high voltages. In order to disconnect the unit
completely, you must disconnect it from the mains.
CAUTION: Protect the unit from the rain and moisture. Ensure that no objects or
liquids enter it. If liquid is spilled into the unit, disconnect it from the mains and consult a
qualified service technician.
Do not place the unit close to heat sources.
4. INSTALLATION
UNPACKING
Before leaving the factory, each intercom matrix has been carefully inspected and tested.
Unpack and inspect the unit for any damage that may have occurred during shipment. If any
damage is found, does not connect the unit to the mains; notify the salesperson immediately; a
qualified service technician should inspect the unit.
Save the original packing, you could use if you need to transport the unit. NEVER SHIP THE
INTERCOM MATRIX WITHOUT ITS ORIGINAL PACKING.
MOUNTING
It is always recommended to mount the unit in rack, either for mobile or fixed installations, for
protection, safety, aesthetics, etc.
The ALTAIR MTX-416 is designed for standard 19" rack mounting, and takes up 1u high rack
space.
CHANGING THE FUSE
This unit incorporates an internal, worldwide voltage operation power supply, and it is
prepared to work from 90 to 264 VAC, 50-60Hz.
Make sure that the unit is disconnected from the mains.
In the unit rear panel are placed the mains connector, the mains selector and the fuse holder.
The box bellows this mains connector is called fuse holder. Take out the fuse holder.

After extracting the fuse holder, the fuse will appear, take out it and
change for the new one.
Insert the fuse holder into the mains connector again.
Make sure that the fuse is the right one: 2A slow blow type - T2AZ
CAUTION: Always make sure after changing the fuse, that it is the right one.
CONNECTING TO THE MAINS
The connection of the intercom matrix power supply to the mains takes place by
a standard cord included in the box.
Make sure that the unit power switch is at 0 position (turned off).
Insert the female I.E.C. connector of the tripolar cable into the unit power supply
male connector, placed at the rear panel.
Insert the male connector of the tripolar cable into the mains plug.
Turn on the unit power switch. In that moment, all the leds of the unit
will light slightly, indicating that the unit is turned on
CAUTION: Make sure that the mains voltage is the correct as well as their fuse is the right one.
INTERCOM / AUDIO CHANNELS CONNECTION
If we are going to use ALTAIR MTX-416 like intercom matrix, we will connect the intercom
channels CH1-CH4 to a unit with active intercom channels (ALTAIR EF-200, ALTAIR WBS-200, or any
compatible CLEAR COM
TM
). The signal distribution in the PHOENIX
TM
connector is the following one:

If we used the ALTAIR MTX-416 like audio matrix, we will connect the audio channels CH1-CH4
to four audio inputs (for normal mode: 4 IN - 16 OUT) or four audio outputs for the inverted mode
(REVERSE- 16 IN - 4 OUT). The signal distribution in the PHOENIX
TM
connector is the following one:

INTERCOM / AUDIO LINES CONNECTION
If the ALTAIR MTX-416 unit is used like intercom matrix, we will connect the intercom lines L1-
L16 to a unit with intercom passive channels (ALTAIR ES-200, ALTAIR EM-201, or any compatible
CLEAR COM
TM
). The signal distribution in the PHOENIX
TM
connector is the following one:

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
possibilities:
