CLASSÉ DESIGN PHILOSOPHY
All of our components benefit from the same
rigorous design goal: All Classé products must
reproduce music with the harmonic and spatial
integrity typical of fine instruments heard in a
live, unamplified performance.

Single Circuit Design
To this end, we make extensive use of
carefully optimized versions of the same basic
circuit precisely matched to specific power
requirements. This means that all Classé line
level components and power amplifiers benefit
from years of refinement. However, our efforts
do not stop here.

Listening: The Critical Design Element
Once we determine general circuit values
for a particular application, we listen carefully
while exchanging and mixing different parts
(transistors, capacitors, wiring, PC boards, etc.)
and adjusting specific operating voltages within
proper engineering ranges.

Extended Real-World Lifespan
Every Classé component, even the most
affordable, benefits from our painstaking
approach to design parameters. The result is an
optimum balance between the often-conflicting
demands of exceptional performance and long-
term reliability. Our most expensive components
gain from even tighter tolerance parts and highly
segmented and exceptionally robust power
supplies with large reserve-current capabilities.

Our Pride in Manufacturing, Your Pride
in Ownership.
We build all of our components to the highest
possible standards. From multi-layer glass-epoxy
circuit boards, the full sized power-supplies, and
the massive faceplates, every Classé product is
a tribute to both the science and art of sound
reproduction. We hope that you derive as much
pleasure and satisfaction in using your Classé as
we did in producing it.

UNPACKING & SET-UP
Your CLASSÉ CP-35 preamplifier has been
carefully wrapped in heavy gauge plastic, packed
in semi-rigid foam and contained in a special
box. To remove the unit, open and spread the
top flaps of the box. By its sides, lift out the
entire unit with foam pieces intact. Remove each
foam side by pulling straight out. Remove the
plastic wrap and inspect the unit for any
concealed damage. Apart from this owner's
manual, please ensure the follow-ing has also
been included:

This preamplifier, being capable of very high
gain, must be located in a position free of any
hum-inducing magnetic fields. (This also applies
to turntables and interconnect cables.) Positions
adjacent to power amplifiers, A.C line filters, or
regulation devices should be avoided. Ideally, a
few feet should separate the preamplifier from
the power amplifier. As well, keep low-level
interconnect cables away from the power amp
and separate from A.C. linecords.

Heat generated by the preamplifier is negligible.
Air space around the unit need not be a concern.

A.C. LINE POWER
The Classé CP-35 preamplifier has no power
switch. Its low power consumption and improved
sonics from always being ON led to the omission
of an ON/OFF switch. In fact, while thoroughly
musical shortly after turn-on, the preamplifier will
exhibit “sonic growth” during its first 300 hours
of use.

For optimum sonic performance, you should
consider the use of the optional CLASSÉ
REFERENCE A.C. LINECORD. Consult your
dealer regarding this accessory.

Safety Feature:
The CP-35 preamplifier is designed with an
auto-muting circuit which engages during the
initial 20 seconds count down and is indicated
by MUTE at the right of the display when the
unit is first connected, or after an AC power
failure. After the 20 seconds countdown, the
MUTE signal at the right of the display will be
ON thus showing that the unit is in MUTE mode.

This feature will prevent any turn-on surges
or unstable output from reaching the power

make sure the MUTE is ON again when removing
A.C. line power.

CAUTION: Disconnect AC line cable while
making all connections. “Floating the ground”,
or defeating the ground on a 3-prong linecord
may create a shock hazard. Connect all
interconnect cables between the electronics
before connecting the A.C. linecords to the wall
outlets. This will reduce the potential shock
hazard. See also the warranty section of this
owner's manual.

INPUTS
The input jacks are clearly marked on the back
of the CP-35. The following inputs are provided:
LINE 1, LINE 2, LINE 3, LINE 4, BAL 1 and TAPE
(see fig. 3).
LINE LEVEL INPUTS LINE 1, LINE 2, LINE 3 , and
LINE4: These are all high level inputs sharing
exactly the same characteristics, and may be
interchanged if so desired. A tape machine
should only be connected to the TAPE input. See
TAPE IN and TAPE OUT below. The LINE 1 input
could also be fitted with an OPTIONAL PHONO
BOARD plug in module installed in the unit. A
ground screw is provided adjacent to the LINE 1
input jack.
