Mark Levinson No5302

Mark Levinson No5302

The Mark Levinson No5302 blends the finest materials, technology and artisanship for exceptional beauty and performance.

A powerful fully-discrete, direct-coupled, dual-monaural, class AB amplifier that is bridgeable for monaural operation, the No5302 delivers all the performance and quality expected from Mark Levinson with exceptional value and exibility.

EVOLUTION

The No5302 amplifier was created to deliver all the performance and quality expected from Mark Levinson with exceptional value and accessibility to a broader range of customer.

AMPLIFICATION

The fully discrete, direct-coupled, class AB amplifier channels get their power from an oversized 1100 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 No534 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 135W/channel at 8 ohms, 270W/channel at 4 ohms, and 55W bridged in Mono and stable operation @2 ohms.

CONTROL

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 No5302.

Finally, an internal webpage allows setup, import and export of configurations, and software updates using a PC and standard web browser.

INDUSTRIAL DESIGN

Lavish nishes, and bold geometry are hallmark attributes of Mark Levinson designs.

The one-inch-thick, bead-blasted, black-anodised, solid aluminum front panels are machined and contoured to ow seamlessly into the sleek glass display, which itself is recessed into a bead-blasted, clear-anodised aluminum bezel.

A light ring accentuates the large aluminum standby button, while subtly communicating power states.

Cosmetic grade solid aluminum handles and forty-two tri-grouped heat sync ns per side, express robust beauty and function.

With meticulous details, including, debossed top cover vents, screen-printed logo and legends behind the glass panel, and custom machined aluminum feet, the No5302 exudes elegance and style.

The Mark Levinson No5302 is proudly designed, engineered and precision crafted in the USA.

All production No5302 units will undergo 100% functional testing prior to shipment, and the following features and electrical measurements will be verified on all units.

All production units will meet or exceed all specifications listed below.
