Three Primary Modes of Amplification:

Radio Controlled
Connect the antenna output of your handheld transceiver to the RF-IN connector on the rear panel of the amplifier using the Radio to Amplifier RF cable. This allows you to transmit and receive using your handheld radio while amplifying the output signal.

Accessory Controlled
Connect the antenna output of your handheld transceiver to the RF-IN connector on the amplifier. Then, connect a speaker microphone, headset, or compatible accessory to the radio. This setup enables you to transmit and receive through the accessory while amplifying the output signal.

Amplifier Controlled
Connect the speaker microphone to the MIC jack on the front panel of the amplifier. Connect the antenna output of the handheld transceiver to the RF-IN connector on the amplifier using the Radio to Amplifier RF cable. Finally, connect the accessory port of your radio to the Control jack on the front panel of the amplifier using the Amplifier Control Cable. This allows you to transmit and receive using the speaker microphone on the amplifier while incoming audio is relayed through the loudspeaker.
