4 CHANNEL POWER AMPLIFIER - MRV-F300
Tens of thousands have relied on V-Power amplifiers for dependable, quality power. Now in their fourth generation, V-Power amplifiers carry on this heritage and prove that playing strong never looked our sounded better. Yes, it is possible to improve upon a good thing.
Overview
Total Max Power: 640 W
75W RMS x 4 (2Ω, 14.4V, ≤1% THD+N)
50W RMS x 4 (4Ω, 14.4V, ≤1% THD+N)
Same power in a 40% smaller chassis
Evolution to Class D digital platform
New snap-on terminal covers for easy installation
