The fully discrete, direct-coupled, class AB amplifier channels get their power from an oversized (500+ VA) toroidal transformer with individual secondary windings for the left and right channels. The voltage gain stage employs a topology directly descended from the acclaimed Nº 534 amplifier, which is mated to an output stage comprising two high-speed driver transistors operating in class A and six 260V, 15A output transistors. Two Thermal-Trak devices in a unique configuration guarantee stable output bias regardless of load or temperature. Four 10,000-microfarad capacitors per channel, located directly on the output stage circuit board, easily provide enough current for a conservative 125W/channel at 8 ohms, nearly 250W/channel at 4 ohms, and stable operation down to 2 ohms. Variable line-level RCA outputs allow system expansion and flexibility.
System integration and communication ports include Ethernet, USB, RS-232, IR input, and 12V trigger input and output. A newly designed, solid aluminum IR remote is included with the Nº 5805. Finally, an internal webpage allows setup, import and export of configurations, and software updates using a PC and standard web browser. In addition, third party drivers are available.
Bold new industrial design
Robust materials, lavish finishes, and striking geometry are hallmark attributes of Mark Levinson designs. The one-inch thick, bead-blasted, black-anodized, solid aluminum front panels are machined and contoured to flow seamlessly into the sleek glass display, which itself is recessed into a clear-anodized aluminum bezel.
The iconic Mark Levinson hourglass knobs are redefined – machined with a gently curved profile transitioning into a rounded front, with feet to match. With debossed top cover vents, screen-printed logo behind the glass panel, and aluminum buttons, no detail has been overlooked. An elegant 5000 Series custom aluminum IR remote control is included.
