The Powersoft PRIMA 164 is an ultra-compact, 1U half-rack professional power amplifier delivering 160W of reliable low-to-mid power amplification across 4 channels (4 x 40W). Designed specifically for small-to-medium installed audio systems where signal processing is already handled upstream, the PRIMA Series eliminates redundant onboard processing to bridge the gap between entry-level commodity amplifiers and fully featured, DSP-integrated platforms. It features a clean, zero-software hardware interface with local controls for immediate deployment.

Key Features

• No Redundant DSP Architecture: Built for environments where routing and control are managed by a centralized upstream matrix, mixer, or AV processor.
• Fixed Diagonal Matrix Routing: Signal flow is clean and predictable out of the box, with each physical audio input directly feeding its corresponding output channel.
• 1-to-All Routing Connector: Includes a dedicated rear-panel hardware connector that instantly feeds a single input source across all 4 output channels.
• Lo-Z and Hi-Z Versatility: Each channel is independently configurable to drive low-impedance or 70V/100V distributed loudspeaker lines without needing external transformers.
• Power Sharing Technology: Dynamically distributes the amplifier's power reserves across channels based on real-time acoustic demand to optimize system efficiency.
• Automated On-Site Deployment: The Auto Setup routine optimizes operational parameters on the very first start-up, significantly slashing on-site commissioning time.
• Flexible Standalone or Discreet Mounting: The ultra-compact half-rack chassis allows discreet installation out of sight, including behind displays, under conference tables, or side-by-side in a standard rack.
• Software-Free System Monitoring: Features on-board gain trimmers, status/signal LEDs, and straightforward rear-panel controls for immediate physical adjustments without needing configuration software.
• Reduced Energy Footprint: Built-in Eco Mode, Auto Standby, and low-consumption operation minimize the long-term energy footprint of the venue.
