Control Panel
Beltpack Transmitter Transmits Voice to the Infrared Ceiling Sensors
CAUTION:The included PI30-SP speakers have a total impedance of
about 5.3 ohms when connected in parallel. Therefore, no more
than 2pcs PI30-SP should be connected to the PA-IRSYS to avoid
the impedance dropping too low for the amplifier output. Speakers
with higher impedance ratings can be used as long as the total
load impedance on the amplifier is not below approximately
3 ohms.
The Control Panel has two possible mounting configurations:
1. Option 1: The default configuration is the surface-
mount the box on the wall. The mounting ears are
designed with 4 holes for screws. Wall anchors or other
hardware should be used as necessary to securely
attach the box to the wall.
2. Option 2: The second configuration is a flush-mount.The
mounting ears can be unscrewed, flipped around and
unscrewed into the holes towards the front of the box.
In this configuration, a hole will need to be made in
the wall the same size as the control panel. The control
panel will protrude from the wall only enough to allow
for the door to open fully.

signal for playback through the system. The volume
for the inputs can be controlled by the Aux Volume
Controls (9,10).
Turn all the Volume Controls to their minimum position
(approximately 7 o’clock). The Treble and Bass (11, 12)
controls should set to 12 o’clock (straight up).
Turn on the Power Switch (2) and the power LED
Indicator will light.
The PA-IRSYS should now be operational. The Treble
(11) and Bass (12) Control knobs can be adjusted to
improve quality/intelligibility of the audio through the
system.
Note that the Master Volume must be also turned up for
the signal from the paging system to be heard through the
PA-IRSYS speakers. Due to this, the PA-IRSYS should not be
relied on for emergency paging or announcements.

•
Because the PA-IRSYS wireless microphones use infrared
signals, they are not suitable for outdoor use since direct
sunlight can interfere with the transmission.
Do not cover the infrared transmitter head on either the
handheld microphone or the belt pack microphone as
the transmission to the ceiling sensors requires line-of-
sight for clear noise-free operation.

Beltpack Battery Compartment (9), paying attention to the
positive and negative poles. Then close the battery cover
Turn on the Microphone Power Switch (1) and the power
LED indicator will light, indicating that transmitter is ready
to use. A couple seconds later the appropriate IR Signal LED
(5, 6) will light red, meaning the receiver has good signal
reception from that particular mic.
If using the beltpack transmitter, adjust the VolumeControl
(7) on the side of the beltpack. Also, adjust the appropriate
Wireless MicVolume Control (7, 8) on the panel.The Master
Volume will also need to be adjusted to an appropriate level
At this point, the microphones should be heard through
the system.
Both of the wireless microphones can be used throughout
a typical day on a single charge and should be recharged
overnight while not in use (without taking out batteries).
Both the Beltpack and Handheld Mics have Built-in
Chargers (14, 17) and are to be placed into their respective
charging stations and charged overnight.
The LEDs on the Handheld and Beltpack Microphone
chargers indicate when the system is charging the
microphones and when charging is complete. The LEDs
will light up red when charging and will turn green once
the batteries are fully recharged.

the Mic Pre-out (25) to the line input on the computer.
Connect the PC line/headphone output to the Aux 1
(22) or Aux 2 Input (24) on the Control Panel.
By connecting the system in this configuration, all of
the microphone signals from the PA-IRSYS (the wireless
teacher & student mics, and connected wired mics 1
and 2) are mixed and sent into the PC and sent to the
remote teleconference site. The microphone signals will
still also come out of the PA-IRSYS speakers along with
the audio from the remote teleconference site.
You can adjust the Master Volume (13) and Aux Input
Volume (9, 10) to get an appropriate loudness and mix
of the signals.

Paging System
There is noise or hum from the speakers.
• Check the installation:
The output of a 25 / 70 / 100 V Paging System may be
connected to the PA-IRSYS paging input for non-emergency
paging.
• Ensure that cables are as short as possible
and not run next to noise-generating cables
or equipment.
• Ensure that power cables of different
equipment use the same power outlet
to avoid ground loops.
1.
To do this, first wire the paging system output to the
included 2-pin phoenix connector.
Then plug the connector into the paging input jack.
