Biamp REVAMP4120T 4 Channel Class D Amplifier

Biamp REVAMP4120T 4-Channel Class D Digital Power Amplifier for 70V/100V and 4-Ohm Systems
The Biamp REVAMP4120T is a professional 4-channel Class D amplifier delivering 4 x 120 watts of power at 100V or 4 ohms, with the flexibility to bridge into 2 x 240 watts at 100V or 8 ohms. Designed for commercial audio installations, multi-zone systems, and distributed sound applications, this amplifier offers high efficiency, flexible configuration options, and exceptional reliability. Its combined convection and fan-cooled design ensures optimal thermal management, making it suitable for demanding environments.

Versatile Multi-Zone Power Distribution
With four independent 120-watt channels, the REVAMP4120T is perfect for multi-zone installations, allowing separate control of audio levels in different areas. Whether you need to power four individual zones in mono, two zones in stereo, or bridge outputs for higher power, this amplifier adapts to a variety of audio system configurations.

Bridgeable Channels for Increased Power Output
For installations requiring more power per zone, the REVAMP4120T features bridgeable channels, allowing users to combine two channels into a single 240-watt output at 100V or 8 ohms. This makes it ideal for large spaces or applications where higher audio output is needed without compromising sound quality.

High-Efficiency Class D Amplification with SMPS Power Supply
This amplifier incorporates a highly efficient switch-mode power supply (SMPS) and Class D output topology, reducing power consumption while delivering strong, clean audio performance. The combination of these technologies ensures a lightweight, energy-efficient amplifier that operates with minimal heat dissipation.

Intelligent Cooling System for Silent Operation
Equipped with a variable-speed fan that activates only when necessary, the REVAMP4120T maintains a quiet operation under normal loads while ensuring effective cooling during high-demand situations. This makes it suitable for noise-sensitive environments such as conference rooms, retail stores, and hospitality venues.

Built-In 250 Hz High-Pass Filter for Horn Speaker Optimization
For installations utilizing horn speakers, the REVAMP4120T includes a built-in 250 Hz high-pass filter. This feature optimizes system performance by filtering out low-frequency signals, ensuring cleaner sound reproduction and improved clarity in paging and voice reinforcement applications.

User-Friendly Interface with Intuitive Display and Limiter Protection
The front panel display provides clear visual feedback on amplifier status, making it easy to monitor performance at a glance. An integrated limiter ensures the output remains controlled without introducing distortion or excessive compression, preserving dynamic sound quality while preventing system overload.
