Key Features of RT91 Amplifier

• Dual-Mode Compatibility:

  The RT91 amplifier supports both digital and analog systems, automatically recognizing and adapting to each. It is compatible with DMR, dPMR, D-STAR, C4FM, and analog FM systems.

• Compact and Lightweight:

  With dimensions of 139x115x36mm and a weight of just 700g, the RT91 is ideal for field operations without adding significant bulk.

• Cleaner Output Signal:

  Harmonic filters on the input ensure that the amplifier transmits a cleaner, purer signal from your handheld two-way radios.

• Handheld Radio Support:

  The RT91 amplifier works with any handheld radio that outputs 2W–6W. Ensure the frequency range matches your radio before purchasing, as UHF or VHF bands are available.

• Supported Amplification Modes:

  The amplifier operates between 136-174 MHz or 400-480 MHz and supports various modes, including analog FM, P25 Phase 1, C4FM (System Fusion), NXDN, IDAS, dPMR, and MPT1327.

• Built-in Loudspeaker:

  When connected via a radio control cable, the amplifier uses its powerful 4W built-in speaker to broadcast incoming audio clearly.

Three Primary Amplification Modes:

• Radio Controlled:

  Connect the antenna output of your handheld transceiver to the RF-IN connector on the amplifier's rear panel. Your output signal is amplified while you transmit and receive directly on the handheld radio.

  
• Accessory Controlled:

  Connect a speaker microphone or compatible accessory to the handheld transceiver, while the amplifier enhances your output signal.

  
• Amplifier Controlled:

  Connect the speaker microphone to the amplifier's MIC jack and the handheld transceiver to the RF-IN connector. The amplifier controls the transmission, while incoming audio is broadcast through the amplifier's loudspeaker.
