Mark Levinson No532 - Manual (Page 5)

I/Os
The first non-Reference Mark Levinson amplifier to
be fully differential, the N
o 532 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.
C ONTROL AND C OMMUNICATION
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 N
o 532
features ML Net and Link2 functionality.
These are proprietary Mark Levinson
protocols for communication between two
or more similarly equipped Mark Levinson
components. The N
o 532 can be easily integrated
with and controlled by other Mark Levinson
devices, with functionality that includes automatic
on/standby toggling and LED synchronization. The
N o 532 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.
T HE N O 532 E XPERIENCE
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 N o 532 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 N
o 532
combines truly impressive output and remarkable
sound quality – as we’re certain even reticent
audiophiles will readily acknowledge.
The N o 532 has separate AC Mains boards in
order to ensure that the most appropriate
parts and circuit topology are used for
the incoming voltage.
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.
