AL2430-2PH Installation Description
1. Unpack AL2430-2PH system and confirm all components are present and undamaged.
2. Find suitable location for the AL2430 Receiver / Amplifier within 10' of a 120VAC outlet.
3. Find suitable location for the AL-Dock battery charger within 6' of a 120VAC outlet and insert both AL-PH microphones.
Note: The batteries must charge for 8 hours before use.
4. Route supplied RG-6 coaxial cable from AL2430 to AL-IRDS. An appropriate location is high on a wall, on the ceiling, or somewhere
it will have a line of site view from the AL-PH transmitters.
5. Install appropriate 70.7V speakers and route a 2 conductor unshielded cable from the AL2430 to the speakers. Set the appropriate
tap for the speakers being conscious of the 30 Watts maximum output of the AL2430 amplifier.
6. Connect the audio output of all the associated multimedia sources to the appropriate input on the rear of the AL2430 Receiver /
Amplifier.
7. Once all the external wiring is complete and the AL-PH batteries are changed turn on the AL2430 Receiver / Amplifier and set all
front panel volume controls to the “9 o’clock" position.
8. Set one AL-PH wireless microphone to IR Channel A and the other AL-PH wireless microphone to Channel B.
Power on both wireless microphones by holding each power button for three seconds and confirm that the appropriate IR Channel
LEDs on the AL2430 are illuminated. Confirm each microphone is set to Mode 1 (the left blue LED should be illuminated) if not
press the Mode button.
9. Speak into the microphone and press the Up Volume button on the AL-PH until the desired volume is reached at the speakers.
If the appropriate level cannot be attained, increase the front panel Channel A or B volume on the Receiver / Amplifier until
maximum volume without feedback is reached and then adjust the microphone volume on the AL-PH microphone for proper
listening level.
10. Press the Mode button on the AL-PH to activate Mode 2. Start one of the multimedia sources and hold the Up Volume button on
the AL-PH until the desired volume is reached at the speakers. If the desired level cannot be attained, increase the front panel
volume control of the appropriate input until maximum listening volume is reached, then adjust the microphone volume for proper
listening level.
11. Perform step 10 for each of the multimedia inputs needed and step 9 for the other microphone.
12. Walk around the room while speaking into the microphone to confirm there are no signal dropout locations. If a signal dropout
location is found, try to relocate one of the AL-IRDS antennas.
Wiring the AL2430
Speaker Outputs
Use 2 conductor unshielded wire of the appropriate gauge.
If you are unsure about this, contact Atlas Sound Tech Support at 1-800-876-3333.
Make sure you know how many speakers you need and what tap value you intend to use.
IR Domes
Use supplied RG-6 coaxial cable. Both ends of this cable are pre-terminated with “F” type connectors. If the supplied cables are
not sufficient for the install then both ends of the installed RG-6 cable will need to be terminated with “F” type connectors.
Unbalanced Inputs and Outputs
Pre-made RCA cables can be purchased from vendors to simplify interconnection to external devices
Priority Page Input
Use 2 conductor unshielded wire of the appropriate gauge.
