IR +
IR M1
QUICK START GUIDE
Setup Overview
1. Place your IR M1 in a location where you will be able
to place the IR emitters connected to the IR M1 in the
listening area.
2. Plug in the power supply to the power connection on
the IR M1.
3. Connect an audio source to the Line/Mic In port for the
channel(s) you’d like to use.
4. Connect an Ethernet cable to the ETHERNET port.
Connect the other end of the Ethernet cable to a
multicast-enabled router with an internet connection.

5. Connect one or more IR E4 emitters to Output to
Emitter ports on the back of the IR M1 with an CAT5e
cable. No additional power is required.
6. Place the emitters in the listening area so that they
are above the audience without interference. Multiple
emitters should be place apart from one another to
expand the coverage area.
7. Turn on the IR M1.
8. On the front panel of the IR M1, a IP address should
be displayed. If you do not see an IP address, check
your network connection. Write it down and go to a
computer. on the same network as the IR +.
9. In Chrome or Edge, type the IP address into the URL
bar. A webpage for the IR + system will load. The
default usename is admin and the default password is
admin.
10. Click the Audio tab and set the audio device type and
desired settings for each audio channel.
11. Click the Settings tab. Configure each emitter for the
channels it will broadcast, and the IR Band the system
should emit.
12. Change other settings as desired.

13. With your audio source playing sound, take an IR
Receiver to the front panel of the IR M1. The front panel
of the IR M1 has two small IR Emitters for testing, one
for each audio channel. Tune the receiver to the IR
Baseband channel the audio is playing on to ensure all
your settings sound correct. This audio will match the
audio from the IR E4 emitters.
14. For more advanced system setup, please see the full
user manual.
Configuration Details
The IR M1 Modulator is the key component to the IR+
System. Audio devices, emitters and more can be
connected to the IR M1. Any configuration to the IR+ system
is done through the IR M1, which passes the configuration
setting onto other IR+ devices.
Determine Coverage Area and Location
The modulator is usually located with the sound system
amplifier or mixer for easy access to an audio input signal.
For portable systems, the modulator can be placed near
the emitter or in another convenient location.
The emitters will need to be placed to get the most
coeverage area. When using the IR Plus system in single-
channel mode with the RX22-4 receiver, the system
coverage area will cover up to 18,000 sq. ft. (1,673 sq. m.)
per IR E4 emitter. The IR E4 will use full power, single
channel mode by default. Single channel or dual channel
mode, and emitter output power, can be selected using the
system webpage.

The coverage area may be aected by direct/indirect
sunlight, reflections on walls and room construction.
Reflections of the infrared light from walls, ceilings, and
floors may change these patterns.
Important: Remember to point the emitter towards the
listening audience.
Remember: Most objects block infrared light. The
transmitter cannot be concealed behind walls, glass,
curtains, etc.
These patterns are the direct radiation pattern. The infrared
radiation does not drop to zero outside the illustrated
patterns; it decreases. It still may be usable at a greater
distance, depending on the receiver sensitivity and the
reflective characteristics of the room.
Do not paint the front face of the IR E4.
Network Cable Connection
The Ethernet port can be used to connect the IR M1 to a
local network. A network connection is required to access
the IR M1 webpage. The webpage is needed to configure
some device settings after the system is set up.
An Ethernet connection alone will not allow the Wi-Fi
broadcast features to work; a Wi-Fi connection must be
available on the network. A network connection is not
required for broadcasting over infrared.
Once a connection has been established, an IP address will
automatically be assigned to the IR M1. Device settings can
then be set via the web interface, including changing any
network settings.
NOTE: Most settings need to be set BEFORE connecting
audio sources.
Cable Connection to Emitters
The IR M1 can directly drive four emitters. Emitters repeat
the baseband signal, so any number of emitters can be
used. The modulator outputs CANNOT be split with CAT5e
splitters.
Determine the length of RJ-45 cable needed to reach from
the Emitter to the Modulator unit. For more information
on cabling, please read the full user manual (see “For
Additional Information” on page 2).
Audio Source Connections
The IR + transmitter will accept the following audio sources:
1. Balanced Microphone with or without 12 volt phantom
power (DIN 45596) on a 3-pin (XLR) connector.
2. Balanced/Unbalanced microphone with or without
phantom power on 1/4 inch (TRS) jack
3. Balanced/Unbalanced Line on a 3-pin (XLR) connector.
4. Balanced/Unbalanced Line on 1/4 inch (TRS) jack.
5. Dante on an RJ-45 jack (optional).
WARNING:
The IR + is not designed to accept 70 volt speaker
signals! This may result in damage to your system.
The sound source should come directly from the
system mixer or digital source as a low-level or unprocessed
signal.
For specific audio wiring information, please read the full
user manual (see “For Additional Information” on page
2).
Network Configuration
Network Settings can only be edited from the web interface.
An IP address will be automatically assigned to the IR M1
once an Ethernet cable has been connected to the device
and network connection found. Additional configuration
would need to be made through the web interface.
Web Control Interface
The IR M1 provides a web interface to manage the device
settings. These web pages can be accessed over either a
hardwired or wireless network connection with the Chrome
browser.
Changes take eect when applied or saved. Any updates
made through the front panel will show up on the web
interface once the current page has been navigated away
from, either by refreshing the page or going to a new page.
1. Open Chrome.
2. In the address bar of the browser, type in the IP
address of the IR M1 and hit Enter.
3. You should see the Login Page of the IR M1 and can
adjust settings from here.
4. For more information, please read the full user manual
(see “For Additional Information” on page 2).
