AL2430-2PH Function Description

42

The versatile AL-PH Microphone performs the functions of a wireless microphone and a system remote control. It can be used as a Handheld Microphone, a Lapel Microhone with included Lanyard(AL-LANYARD), or a Belt Pack Microphone with optional AL-HSM headset. Each AL-PH has a switch located under the battery door used to set its IR Channel to either A or B. One AL-PH must be set to Channel A and the other AL-PH must be set to Channel B. The system will not function properly if there are two AL-PHs set to the same IR channel.

Also located under the battery door is the LOCKOUT switch. When this is engaged all function buttons are disabled and the unit can be used as a microphone only.

The AL-PH can be set in two different modes that effect the control it has over the AL2430 system.

Mode 1:

• The right side blue LED will be illuminated

• Volume UP / DOWN buttons will control the microphone volume

• The Mute button mutes the microphone

Mode 2:

• Both blue LEDs will be illuminated

• Volume UP / DOWN buttons will control the multimedia inputs on the AL2430 Receiver / Amplifier

• Mute button will mute the multimedia inputs on the AL2430 Receiver / Amplifier

Power and Panic buttons function as described below regardless of microphones mode setting.

The Power button needs to be pressed for three seconds to turn the unit on or off.

When the Panic button is pressed along with the Mode button, a signal is sent to the AL2430 Receiver / Amplifier. This closes its Panic

Output relay. The Panic Output relay can be connected to an external system. For example: the school's Paging / Intercom system to alert someone of an event in the class room that requires immediate attention.

AL2430-2PH Installation Description


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.

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.

Amplifier.

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.

If you are unsure about this, contact Atlas Sound Tech Support at 1-800-876-3333.
