Power amplifiers are core components of any high performance entertainment system. Their task is formidable they must comfort ably drive any of a wide variety of demanding speakers while preserving all the power and nuance of the source material. The ability to maintain sonic neutrality, while exercising brute force or finesse as appropriate, is anattribute that has made Mark Levinson power amplifiers the standard in the industry for nearly 30 years. The Nº436 and Nº434 continue the Mark Levinson tradition in a design that is perfectly suited to multichannel audio and theater installations as well as twochannel systems. A sophisticated thermal management system that incorporates crosscut exposed internal heat sinks makes the Nº436 and Nº434 ideal for systems where space and ventilation are limited. Built to be rackmountable, the Nº436 and Nº434, in combination with the rest of the 400 Series power amps, offer a wide range of options for high end multichannel systems. The physical and sonic properties of the Nº436 and Nº434 are built upon Nº436 & N º434 MONO POWER AMPLIFIERS Nº436 Nº436 Interior

the Mark Levinson power amplifier tradition. The power supply is the foundation that all of the audio circuitry is built upon. Both amps benefit from a massive, dedicated, independ ent linear power supply. Our ongoing listening tests continue to confirm that abun dant clean power is essential for high performance. Precise control of this power reserve is the task of the amplifier's voltage gain and output stage circuitry. Mark Levinson amplifiers have always featured precision circuitry designed to fully exploit balanced signals. Rather than adding opamp buffers, or simply duplicating circuitry for both halves of the balanced input signal as many other amplifiers do, Mark Levinson amplifiers feature an advanced, inherently balanced topology for greater efficiency, performance and sonic benefits. The Nº436 and Nº434 have power ratings of 350 and 125 watts into 8 Ohms, and 700 and 250 watts into 4 Ohms, respectively. As with all Mark Levinson amplifiers, particu lar attention is paid to the layout and circuitry connections. All circuit boards are laid out by our engineers rather than by a computerprogram. These new amplifiers outperform their predecessors in part because of the refinement of circuit layout. Additionally, the ultra high performance parts that make up the balanced circuits are able to work to their full potential because they reside in the most neutral circuit board material known as Arlon 25. The output stage of these new amplifiers is similar to our other power amplifiers. The matched output transistors continue to be the best performing parts available for this appli cation and they are mounted directly to the exposed internal black anodized aluminum heat sinks. The Nº436 and Nº434 set a new standard for multichannel and theater audio. Powerful, elegant, and musical, these remarkable prod ucts combine stunning audiophile performance and system flexibility without compromise. Nº434
