General Notes
• The Master Volume controls the overall volume of the
system. If the master volume is not up, then no sound will
be output from the system speaker outputs.
• 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.
Troubleshooting
There is no sound output.
• Is the AC cord connected the Control Panel and
to the power outlet?
• Is the power switch on and the power LED lit?
• If using the beltpack transmitter:
• Is the power on the beltpack on and the
power LED on the beltpack is lit?
• If not, try new batteries.
• Is the Teacher Mic Signal Indicator lit
on the Control Panel?
• If not, make sure the ceiling sensors
are picking up the signal from the
beltpack and that the IR transmission
is not being blocked.
• Is the volume control on the beltpack up?
• Is the Teacher Mic volume control up?
• Is the Master volume control up?
• Are the speakers connected to the speaker outputs?
There is feedback from the speakers.
• Try decreasing the volume of the
microphone, master volume control, etc.
until there is no feedback.
• Try adjusting the treble and base controls
to reduce feedback.
There is noise or hum from the speakers.
• Check the installation:
• Ensure that cables are as short as possible
and not run next to noise-generating cables
or equipment.
• Ensure that power cables of dierent
equipment use the same power outlet
to avoid ground loops.

stereo signals are automatically mixed down to a mono
signal for playback through the system. The volume
for the inputs can be controlled by the Aux Volume
Controls (9,10).
6. 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).
7. Turn on the Power Switch (2) and the power LED
Indicator will light.
8. 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.
Connecting the System for Teleconferencing
The Califone PA-IRSYS is specically designed to work with
PC/MAC teleconference systems such as Microsoft®
Netmeeting.
1. When using a computer teleconference system plug
the Mic Pre-out (25) to the line input on the computer.
2. Connect the PC line/headphone output to the Aux 1
(22) or Aux 2 Input (24) on the Control Panel.
3. By connecting the system in this conguration, 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.
4. You can adjust the Master Volume (13) and Aux Input
Volume (9, 10) to get an appropriate loudness and mix
of the signals.
Note: You may need to adjust volume settings of the
microphones as appropriate to get a good level signal into
the computer. You may also need to adjust sound settings
in the application to use the appropriate inputs/outputs
for the audio on your computer.
Tip: Do not connect the Mic Pre-out to the microphone
input of the computer as you may get a distorted sound.
Connecting the System to a 25 / 70 / 100V
Paging System
The output of a 25 / 70 / 100 V Paging System may be
connected to the PA-IRSYS paging input for non-emergency
paging.
1. To do this, rst wire the paging system output to the
included 2-pin phoenix connector.
2. Then plug the connector into the paging input jack.
3. Adjust the sensitivity switch to the appropriate setting.
4. Adjust the paging input volume to the desired setting.
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.
Operating the Infrared Belt Pack
and Handheld Microphones
Notes:
• The volume adjustments for the two wireless mics, the
two auxiliary inputs, and the Master System controls
described in the following section are found on the front
facing panel.
• The Beltpack Transmitter comes with a lanyard that can
be slipped over the belt pack and hung around the neck.
1. Insert two 1.2V AA rechargeable batteries into the infrared
Beltpack Battery Compartment (9), paying attention to the
positive and negative poles. Then close the battery cover
2. 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.
3. If using the beltpack transmitter, adjust the Volume Control
(7) on the side of the beltpack. Also, adjust the appropriate
Wireless Mic Volume Control (7, 8) on the panel. The Master
Volume will also need to be adjusted to an appropriate level
4. At this point, the microphones should be heard through
the system.
5. 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.
6. 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.
