Mark Levinson №5302 Bridgeable Dual-Mono Stereo Amplifier – Mark Levinson

The Mark Levinson № 5302 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 № 5302 delivers all of the performance and quality expected from Mark Levinson with exceptional value and flexibility.

Evolution
The № 5302 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 № 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 135W/channel at 8 Ohms, 270W/channel into 4 Ohms, and 55W bridged in Mono and stable operation into 2 Ohms.

Control
System integration and communication ports include Ethernet, USB, RS-232, IR input, and 12V trigger input and output. Finally, an internal webpage allows setup, import and export of configurations, and software updates using a PC and standard web browser.

Industrial Design
Lavish finishes, and bold 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 bead-blasted, clear-anodized 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 fins 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 № 5302 exudes elegance and style. The № 5302 is proudly designed, engineered and precision crafted in the USA.
