Electro-Voice RE3 RF Amplifier

The Electro-Voice RE3 RF Amplifier is a compact, rugged RF amplification solution designed to extend the reach of low-power signals across a broad spectrum. Built for professional environments—from live stages and broadcast studios to field deployments—the RE3 delivers clean, reliable gain within its specified frequency range up to 960 MHz. This RF amplifier is engineered to preserve signal integrity, reduce noise, and maintain linear performance, ensuring that every transmitted audio or data signal remains clear and consistent as it travels through wireless links, RF distribution systems, or stage communication networks. If you need to push weaker RF signals to higher power levels without compromising quality, the RE3 is engineered to meet demanding performance criteria while remaining easy to integrate into existing setups.

• Broad frequency range and high-frequency capability: The RE3 RF Amplifier is designed to operate across 470 MHz to 960 MHz, covering essential bands used by wireless microphones, in-ear monitoring systems, and other RF link applications. Its versatility makes it suitable for multiple wireless configurations, enabling you to support diverse gear within a single amplifier chassis. This wide span helps you future-proof your setup as you add new equipment that falls within the same RF footprint, reducing the need for additional amplifiers or adapters.
• Low-noise, high-linearity design for signal integrity: In RF amplification, preserving the quality of the original signal is as important as increasing its power. The RE3 prioritizes low noise figures and linear amplification to minimize distortion and spectral spreading across the passband. This means clearer audio, more reliable data transmission, and less interference when you’re operating close to other RF devices on the same site. For performers, technicians, and engineers, this translates to fewer dropouts and more consistent performance during critical events.
• Rugged construction with professional-grade shielding: Encased in a durable metal housing and engineered with shielding that protects against external EMI, the RE3 is built for challenging environments—on the road, in studios, or at outdoor venues. The solid chassis helps dissipate heat, reduces electromagnetic interference, and provides a stable platform for mounting in racks or field cases. The result is dependable operation even under demanding conditions where portable, reliable RF amplification matters most.
• Easy integration with common RF ecosystems: The RE3 is designed to work seamlessly with a variety of RF systems, connectors, and impedance standards used in professional audio and communications setups. Its compatibility with typical RF input and output interfaces means you can integrate the amplifier into existing signal chains without extensive rewiring. This makes it an efficient upgrade path when you need more headroom in your wireless links without rearchitecting your entire system.
• Energy-efficient performance with practical installation benefits: Aside from delivering essential gain within the 470–960 MHz window, the RE3 emphasizes efficient power usage, helping to minimize rack heat output and extend operational life in demanding environments. The compact footprint and straightforward installation options save time during setup, enabling quick deployments for tours, events, or studio sessions while maintaining professional-grade performance.

How to install Electro-Voice RE3 RF Amplifier

• Plan placement in your rack, case, or compact enclosure to ensure adequate ventilation and access to input/output connectors. Avoid enclosing the unit in tight spaces where heat could accumulate, and maintain clear airflow around the amplifier.
• Mount the RE3 securely using appropriate rack ears or mounting hardware if applicable. Verify that mounting surfaces are stable and that the device is oriented to promote optimal cooling during operation.
• Connect the input from your RF signal source to the amplifier’s input using proper impedance-matched cables. Use high-quality RF cabling with suitable connectors to minimize insertion loss and maintain signal integrity before amplification.
• Connect the amplifier’s output to the next stage in your RF chain—this could be a distribution hub, a receiver, or a load that benefits from the amplified signal. Ensure that the load and subsequent equipment are compatible with the amplifier’s impedance and frequency range.
• Provide the correct power supply per manufacturer specifications and power on the unit. Allow a brief warm-up period, then verify that the amplifier is operational and that the signal is visibly present at the output. Conduct a test with a representative signal to confirm consistent gain across the 470–960 MHz band and to check for unexpected distortion or noise.
