INSTRUCTION MANUAL
for the
JC-2 PREAMPLIFIER
1. INTRODUCTION
The MARK LEVINSON JC-2 PREAMPLIFIER is the distillation of years of
scientific research and careful listening. The amplification circuitry
designed by John Curl combines the advantages of class A, completely
complementary push-pull operation, high open-loop bandwidth, and low
feedback configurations in order to approach perfect solid-state pre-
amplification of the most demanding recorded musical material. Hand-
matched active and passive components not previously used in consumer
audio equipment eliminate subtle forms of error and distortion which
plague sensitive ears.
Mark Levinson Audio Systems utilizes the finest test equipment in its
product development program. More significantly, a large number of our
staff participate in the evaluation of these developments and refine-
ments. When a product is made available, it is only after it has proved
itself on a wide variety of sophisticated sound systems. To realize the
full potential of these developments is a laborious and difficult task.
But - here is a true designer’s choice for the classic system.
2. UNPACKING THE JC-2
Inspect the unit for damage. It should be physically free of dents and
scratches. If the unit has incurred any damage, contact your dealer
immediately. Retain all packing material for future shipping. Ship-
ments made in anything other than the original carton will invalidate
the warranty, unless authorized by factory.
3. INSTALLATION
3.1. Connectors
The JC-2 is equipped with phono connectors for all audio inputs and out-
puts. There are two cannon receptacles for connection to the power
supply. A binding post is provided for ground connections to the chassis
of the JC-2.
