Installation Instructions & Release Notes Mark Levinson

Special Design Features
•Seamless Integration
When the phono modules are installed, the stereo input
connector labeled 7 becomes the phono input connector,
accepting input signals from most phono cartridges. As a result,
the phono modules benefit from all the high-performance
power supply and noise suppression features designed into the
Nº326S, allowing them to deliver exceptional sound quality.
Each phono module relies on the same low-noise power supply
as the main audio circuits in addition to its own local, low-
noise, high-speed voltage regulators.
•Flexible Configuration
Multiple loading and input gain options make the phono
modules compatible with most phono cartridges, including
moving-coil, moving-magnet, high-output, and low-output
designs. Three adjustable jumpers provide 200Ωor 47kΩ
resistive loading; 0 or 10nF capacitive loading; and 40 or
60dB input gain. Convenient gold-plated, solder-less screw
terminals accommodate custom loading.
•Balanced Design
Available on a proprietary Mark Levinson-designed stereo RCA
connector, the phono input provides the same common
mode noise rejection benefits as a balanced XLR connector.
The input gain stage produces a symmetrical pair of opposite
polarity signals, based solely on voltage differences present at
the input. Each balanced signal follows the same signal path,
including identical RIAA equalization.
•Instrumentation Amplifier Stage
Gain is distributed over two stages, allowing ample bandwidth
and open-loop gain for superior performance – even at the
60dB input gain required for moving-coil phono cartridges.
Introduced with the Nº38, the instrumentation amplifier stage
resolves tiny electrical signals from potentially noisy
environments. This method offers high common mode noise
rejection without the limitations of transformer-based designs.
•Precise RIAA Equalization
A balanced pair of RIAA equalization circuits follows the input
gain stages. These circuits include a filter constructed with
0.5% non-inductive metal-film resistors and 2.5% stacked-film
capacitors as well as a subsonic filter below 10Hz for
uncompromised RIAA curve accuracy.
•Arlon Circuit Boards
Arlon® circuit boards respond more quickly to transient sig-
nals in both the high- and low-frequency regions. Arlon also
presents a deeper imaging that reveals more of the subtle
1
Nº326S Preamplifier Phono Modules Installation Instructions & Release Notes

nuances of a recording, imparts a more engaging texture to
the high frequencies, and presents more of the ambience of a
recording. All of these properties work together to yield a
sonic signature that is wider, deeper, warmer, and clearly supe-
rior.
Unpacking
CAUTION
FOLLOW PRESCRIBED ESD PRECAUTIONS (page iii).
When unpacking the phono modules:
•Save all packing materials for possible future shipping needs.
•Inspect the phono modules for signs of damage during ship-
ment. If damage is discovered, contact an authorized Mark
Levinson dealer for assistance making the appropriate claims.
•Locate and remove all items from the packing carton. Contact
an authorized Mark Levinson dealer if the packing carton does
not include all of the items listed in the table below.

1. Resistive Load (RL) Jumper
Moving-coil phono cartridges often benefit from a low-value
resistor termination.
•Leave the resistive load jumper CLOSED to place a 200Ω
resistor load on the phono input.
•OPEN the resistive load jumper to place a 47kΩresistor
load on the phono input.
2. Capacitive Load (CL) Jumper
Low-impedance moving-coil phono cartridges often benefit
from a capacitor termination.
•Leave the capacitive load jumper CLOSED to place a
10nF capacitor load on the phono input.
•OPEN the capacitive load jumper to place no capacitor
load on the phono input.
Note
•When both the capacitive and resistive load jumpers
are OPEN, custom loads are in parallel with the 47KΩ
input resistor. This parallel combination becomes more
significant as custom loads exceed 5KΩin value. Use
the following formula if an exact termination value is
desired: [RL=1/(1/custom load+1/47KΩ)].
•Contact the phono cartridge manufacturer for specific
capacitive and resistive loading recommendations.
3. Input Gain (G) Jumper
Low-output (<5mV) phono cartridges often benefit from more
input gain. High-output (>5mV) phono cartridges often benefit
from less input gain.
•Leave the input gain jumper CLOSED to place 60dB of
gain on the phono input.
•OPEN the input gain jumper to place 40dB of gain on the
phono input.
4. Custom Load Screw Terminals
•Fasten the desired value resistor and/or capacitor to the screw
terminals to place a custom load on the phono input.
•In some cases, manufacturers recommend resistive loads
other than 200Ωor 47kΩ. The screw terminals accommodate
custom loads below 47kΩ.

Nº326S Preamplifier Phono Modules Installation Instructions & Release Notes
To connect the Nº326S to a phono cartridge:
•Connect the associated phono cartridge cable to the stereo
input connectors labeled 7 as shown in the illustration
above.
The Nº326S also includes a phono ground connector, which
provides an earth-reference ground connection for the associated
phono cartridge. Connecting the associated phono cartridge
grounding wire to the phono ground connector grounds the
associated phono cartridge to the Nº326S chassis, which some-
times reduces audible hum and other noise that results from mul-
tiple grounding paths. Otherwise, the ground connection between
the associated phono cartridge and the Nº326S chassis is isolated.
Note
Listen to the associated phono cartridge both with and
without the phono ground connection. Then, select the
connection that results in the best performance.
Making Phono Input
Connections
Installing the phono modules allows the Nº326S to serve as a
phono preamplifier. When shipped the Nº326S includes seven
stereo input connectors that accept line-level input signals from
associated components. Once the phono modules are installed,
the stereo input connector labeled 7 serves as the phono input
connector, accepting input signals from a phono cartridge.
