FOR IMMEDIATE RELEASE
MARK LEVINSON SHOWS THE No326S PREAMPLIFIER
CEDIA EXPO, DENVER, CO, September 14, 2006 — Mark Levinson
is displaying the No326S Stereo Preamplifier. Based on the No320S Preamplifier
and a direct descendant of the critically acclaimed No32 Reference Preamplifier,
the No326S features audio circuits, controls, architecture, and an optional
phono module all adapted from the legendary No32. In fact, some audio
circuits, such as the proprietary discrete volume attenuators, are identical
to those found in the No32.
To offer audiophiles the highest signal purity, the Mark
Levinson engineers have chosen to use an exotic circuit board material,
Arlon 25, in the design and construction of the No326S’ main circuit
board. By utilizing this material in the No326S, the team was able to
conduct extensive listening evaluations and employ subtle component
changes — the result is that the No326S yields an open, detailed
sound with the engaging textural signature that only Arlon 25 can provide.
Featuring a single-chassis design, the No326S achieves
similar separation of audio circuit, control and power supply sections
as the dual-chassis No32. Inside the No326S, these sections are separated
by physical layout as well as a steel shield box that protects against
electrostatic and magnetic interference. Filtered AC power is routed
outside audio circuit sections, providing audio circuits with the quiet,
shielded environment essential for superior sound.
The new No326S offers a series of highly effective noise
suppression and isolation technologies. Two active voltage regulation
stages filter AC power for noise as soon as it enters the chassis. A
high-power stage absorbs line voltage and temperature variations, while
a second high-performance stage provides audio circuits with local high-speed
power. Audio circuit and control sections have separate power supplies,
each with their own low-noise toroidal transformer. The audio circuit
transformer includes a Faraday™ shield to separate AC power from
low-voltage secondaries for improved isolation.
Featuring an advanced dual-mono design, the No326S is
endowed with remarkable channel separation and exceptional sonic imaging.
All audio channels use independent power supplies, communication circuits,
and audio circuits. In addition, each channel’s audio circuits
are located in a separate area of the chassis. This innovative design
isolates each channel from the others, allowing the No326S to produce
vividly rich, three-dimensional sonic images with stunning precision.
For even greater channel isolation, the No326S can deactivate
unused inputs to prevent interference from associated components. When
an input is deactivated, the No326S disconnects the input signal and
ground connection, eliminating ground loop noise between the No326S
and the associated component. As a result, input signals pass through
the No326S without even the slightest interference from other components.
Two Mark Levinson-designed discrete volume attenuator
modules control master volume level with unparalleled accuracy and sonic
neutrality. Constructed with Arlon 25 circuit boards with local power
supply regulation and bypass capacitors, these modules generate optimal
power and isolation for even the most sensitive adjustments. Precision
surface-mounted resistors accommodate adjustments in 1.0 dB increments
up to 23.0 dB and 0.1 dB increments above 23.0 dB.
Unlike other stereo preamplifiers, the No326S is designed
to integrate with multi-channel surround sound processors — minus
the drawback of competing master volume level controls. A unique surround
sound processor mode allows the No326S to deactivate its master volume
level control, passing complete control to the surround sound processor.
With no interference from the No326S, the surround sound processor can
maintain the relative volume level of all channels without distorting
its carefully calibrated input and output levels.
Connectors include three balanced (XLR) and four single-ended
(RCA) inputs. Single-ended input signals are converted to balanced signals
upon entering the chassis, and processed as balanced signals thereafter.
During this conversion process, meticulous balanced circuits preserve
all input signal information, passing it to the power amplifier without
the limitations of more asymmetrical single-ended designs. The rear
panel also includes separate main and record output connectors, as well
as two Link communication ports that make it possible for the No326S
to be included in Mark Levinson Link systems.
A large front panel select knob provides quick selection
of the desired input. When an input is selected, the user just presses
and holds the front panel or remote control setup button to open the
corresponding Set Inputs menu. This can be used to select a custom name,
optimize gain levels, set a master volume level offset or assign record
output connectors to individual inputs.
Following in the footsteps of the No32, the No326S exceeds
all reasonable expectations for a stereo preamplifier. Its flexible
design, including seven configurable inputs, separate main and record
outputs, and full surround sound processor integration, allow it to
accommodate a wide range of demands. Even more, an excess of advanced
technologies protect audio circuits for a superior sound sure to complement
even the most sophisticated home entertainment systems.
