Control and Communication, NO532 Experience

The No532 has separate AC Mains boards in order to ensure that the most appropriate parts and circuit topology are used for

the incoming voltage.

No532 also provides traditional 12V input and output triggers to synchronize On/Standby status with devices that do not include ML Net or Link2 functionality. And an RS-232 port is provided for control by third-party automation systems such as those from Crestron and AMX.

I/Os

The first non-Reference Mark Levinson amplifier to be fully differential, the No532 provides both RCA and XLR connectors that accept balanced signals directly into the input stage of the amplifier, with no additional circuitry. Each phase of the differential input has identical electrical properties. The input and voltage-gain stages are tightly matched to maximize the rejection of common mode signals. Stopping such noise at the input stage prevents it from ever reaching the speakers. And because the amplifier is differential on both the RCA and XLR inputs, it handles signals in their “native” format, ensuring that no noise is introduced through unnecessary signal conversions.

The audio signal output path contains 24 output devices per channel, providing impressive power while minimizing crossover distortion. The output devices are arrayed on two separate output stages, which are placed close to one another for ideally balanced transfer characteristics and maximum cancellation of magnetic fields.

CONTROL AND COMMUNICATION

As music and cinema systems continue to grow more complex, integrating individual components takes on greater importance. To address the

increasing demand for more flexible control and communications capabilities, the No532 features ML Net and Link2 functionality.

These are proprietary Mark Levinson protocols for communication between two or more similarly equipped Mark Levinson components. The No532 can be easily integrated with and controlled by other Mark Levinson devices, with functionality that includes automatic on/standby toggling and LED synchronization. The

THE NO532 EXPERIENCE

Mark Levinson power amplifiers are known – many would say renowned – for performance that actively engages critical listeners on an emotional level. They invite your total involvement in music and movies of any genre from any source, creating a wondrously deep, richly detailed soundstage that seems to extend well beyond the boundaries of your listening space.

The new No532 dual-mono power amplifier is endowed with an expressive voice that renders the entire audio spectrum in astonishing detail with effortless authority, and it draws on a reserve of power that even the most demanding speaker load is unlikely to test.

Equally suitable in a world-class dual-mono system or a multichannel music and theater system, the No532 combines truly impressive output and remarkable sound quality – as we’re certain even reticent audiophiles will readily acknowledge.

Located at the top of each amplifier channel, the voltage-gain (VG) board is made from Arlon 25N PCB laminate. It uses superior components, including WIMA film capacitors and Vishay Bulk Metal® foil resistors. The voltage-regulator (VR) board can be seen in one view sandwiched underneath the VG board.

No532 specifications

The Mark Levinson No. 532 is a high-performance power amplifier that epitomizes the brand's commitment to delivering exceptional audio quality and advanced technology. Renowned for its meticulous craftsmanship and cutting-edge design, the No. 532 combines power, precision, and elegance to meet the demands of audiophiles and music professionals alike.

One of the standout features of the No. 532 is its impressive power output. With a robust 300 watts per channel into 8 ohms and 600 watts per channel into 4 ohms, this amplifier is built to handle even the most demanding speakers with ease. The No. 532 uses a dual-mono design, which ensures that each channel operates independently, minimizing crosstalk and delivering a purer audio signal.

The amplifier employs advanced Class AB topology, striking a balance between the efficiency of Class D and the sound quality of Class A. This design allows the No. 532 to produce warm, natural sound reproduction while maintaining high efficiency and low distortion. The amplifier’s frequency response spans an impressive range, delivering crystal-clear highs, rich mids, and deep, powerful lows.

Another key characteristic of the No. 532 is its exceptional build quality. The chassis is constructed from high-grade aluminum, designed to minimize resonance and interference, ensuring that the audio signal remains uncolored. Furthermore, it features a custom-designed power supply, which provides stable voltage and current to the output stage, enhancing dynamic performance and transient response.

The amplifier is equipped with advanced protection and monitoring features. It includes output current limiting, thermal protection, and DC offset detection to ensure reliable operation, even in demanding conditions. The user-friendly front panel includes LED indicators that provide real-time feedback on performance and status.

Connectivity options on the No. 532 are extensive, including balanced XLR and unbalanced RCA inputs, allowing for easy integration into existing audio systems. It also supports various speaker configurations, making it versatile enough to accommodate a range of setups.

In summary, the Mark Levinson No. 532 exemplifies high-end audio engineering, delivering powerful performance, exceptional sound quality, and a user-friendly experience. Its combination of advanced technology, robust power output, and superior build quality makes it a premier choice for audiophiles looking to elevate their listening experience to new heights.
