Mark Levinson No.534 (Läs test i Ljud & Bild)
Mark Levinson® № 534 är en dual-monoblock förstärkare som använder sig av Pure Path-kretskonstruktion för en högströmsförstärkare med låg återkoppling. Den levererar 250 watt per kanal och arbetar i ren klass A för de flesta lyssningsförhållanden. Den kan fördubbla effekten vid 4 ohm och förblir stabil även med 2-ohms belastning.
Specifikation:
• Pure Path discrete, direct coupled, fully balanced, dual-monaural signal path
• Fully differential class-AB architecture, operates in class A for most listening conditions
• 6000-series aluminum chassis, extremely high precision, exceedingly low tolerances
• Expansive, fine imaging, extended low frequency response/pitch, and natural high frequencies
• Rated for 250wpc into 8 ohms, 500wpc into 4 ohms, with 2-ohm stability
• System-integration connectivity: Ethernet, IP, RS-232, triggers, web monitoring and control
• Painstakingly optimized little negative feedback, bandwidth, slewing, and open-loop linearity
• Custom-designed, low noise toroid with separate secondary windings for each output stage
• Designed and handcrafted in the USA
