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.
