Professional Power Amplifiers for Mission-Critical Audio Systems
High-performance audio amplifiers with intelligent processing for mission-critical applications.
Two Amplifiers, One Platform
Both run the nnounce platform and power your speakers over standard network audio.
ampnode4LS
A high-availability 4-channel amplifier, 4 x 500W and bridgeable to 2000W, built for life-safety systems. Redundant power supplies and hardware failover routing keep the audio path running when failure is not an option.
- 4 x 500W
- 2000W Bridged
- Redundant Power
- Channel Failover
- Auxiliary Bus
- Built-in DSP
- Control I/O
ampnode4
4-channel amplification with power sharing and 600W total output in a compact half-rack unit. On-board DSP and a neural engine deliver flexible multi-zone processing from a single device.
- 600W Total
- Power Sharing
- Auto-Setup
- Half-Rack
- Neural Engine
- Built-in DSP
- Control I/O
