Installation & Operation

Operation & Specifications

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 specifically 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 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.

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, first 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 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

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.

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 different equipment use the same power outlet to avoid ground loops.
