The Peavey Architectural Acoustics ICA 400V is a 400-watt industrial contractor amplifier engineered for commercial audio installations requiring direct-drive 70.7-volt and 100-volt system integration. The unit delivers 200 watts RMS into 4 ohms per channel in stereo operation, with equivalent output into constant-voltage lines, eliminating the need for external step-up transformers. All-steel construction with dual-channel flexibility supports stereo, bridged, and parallel configurations across 4-ohm and constant-voltage topologies.
## Technical Specifications
