AL2430 Installation Description

1. Unpack AL2430 and confirm that the unit is undamaged.
2. Find suitable location for the AL2430 Receiver / Amplifier within 10' of a 120VAC outlet.
3. Route supplied RG-6 coaxial cable from AL-IRDS (sold separately) to AL2430. An appropriate location is high on a wall, on the ceiling, or somewhere it will have a line of site view from the AL-MAGPIE/AL-MYNA (sold separately) transmitters.
4. 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.
5. Connect the audio output of all the associated multimedia sources to the appropriate input on the rear of the AL2430 Receiver / Amplifier.
6. Once all the external wiring is complete and the batteries in the chosen wireless transmitters are changed, turn on the AL2430 Receiver/Amplifier and set all front panel volume controls to the "9 o'clock" position.
7. Set one wireless microphone to IR Channel A and the other 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.
8. Speak into the microphone and press the Up Volume button on the wireless microphone 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 AL2430 until maximum volume without feedback is reached and then adjust the microphone volume on the wireless microphone for proper listening level.
9. Walk around the room while speaking into the microphone to confirm there are no signal dropout locations. If a signal dropout location is found, relocate one of the AL-IRDS antennas.

Wiring the AL2430

Speaker Outputs

Use 2 conductor unshielded, twisted pair stranded 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 RG-6 coaxial cable. Both ends of the cable 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. If you are unsure about this, contact Atlas Sound Tech Support at 1-800-876-3333.
