Control Knob – Great Function and Flexibility
The volume knob operates internal gain
variable circuits which allows you to choose
one of five volume curve options. This
flexibility allows you to select the best
operability based on the combined efficiency
of a specific power amplifier and speakers.
The control knob and the input selector
are manufactured by machining a large
aluminum block. The bold but precise finishing, using NC
machining and the ergonomic rounded form provides a pleasing
aesthetic appearance along with necessary functionality.

Newly Designed 3D Optimized Chassis Structure
Our new 3D optimized chassis features a five compartment
double-deck structure. Each circuit block is housed in its own
compartment so as to place them three dimensionally. This
structure greatly contributes to reducing mutual interference
between circuits and provides the shortest signal path. Thick
aluminum is used for the exterior. The 5 mm-thick steel bottom
chassis is supported at four points using ESOTERIC’s proprietary
‘Pinpoint Foot’ (patent number: JP4075477). Vibrations have
been suppressed effectively and high rigidity has been achieved.
Aesthetics and Integrity of the System
Achieved by Rounded Form
Adding the C-02 will provide an aesthetic integrity to the system.
The front, top and side panels along with the front corners are
made of thick aluminum. The rounded shape of the top panel
and the corners, where there are no screws at all, are inherited
designs from the separate component system of the ESOTERIC
flagship line.

Audio expression, symphonic beauty, artistic passion, a spatial concert hall feel and the excitement of the
audience. Esoteric’s Master Sound Works is an audio product concept that recreates all of the music
information in original master recordings with the most state of the art technology available today.
C-02
A Preamplifier Deeply Involved in Musical Expression
Reaching the Ultimate Height in Analog Audio Technologies,
the C-02 Invites You to the New World of Sonic Impressions
The ESOTERIC’s “Master Sound Works” series welcomes the new stereo
preamplifier, the C-02. A reference model developed to be the most important
component for creating sounds integrative for the system. Preceded by the
acclaimed "K Series", the SACD players boasting seamless stress-free sound, the

design found its culmination in the P-02 and D-02 with their musically evolved
sonics. The C-02 is now being launched to demonstrate the ultimate height of
ESOTERIC’s analog audio technologies which produce musical expression never
Dual-Mono Design for RightLeft Independence
before experienced.
The dual-mono design enables the C-02 to have two sets of
power supply circuits (including two sets of power transformers)
for each of the right and left channels. This was done in order to
eliminate any mutual interference between the channels and to
prevent noise being introduced from the power line. Pure and
clean amplification is the great outcome.
A Fully-Balanced Configuration Gives
an Excellent S/N Ratio
Stereo Linestage Preamplifier
C-02
Signals are received through the fully-balanced input buffer
amplifier design for an individual input system and maintains this
balanced transmission at low impedance so that all inputs can
remain free from common mode noise. This fully-balanced
configuration increases the purity of signal transmission and
provides an absolutely excellent S/N ratio.
ESOTERIC-QVCS
ESOTERIC-QVCS (*) is a volume control system, which takes full
advantage of this unit's pure signal paths. By turning the volume
knob, the gain variable volume of all the four circuits – right and
left channels, positive and negative powers – are activated. In
this way, this system keeps audio signals independent (from
right to left and from positive to negative), so that sounds are
reproduced clearly with good channel separation and accurate
phase characteristics. Furthermore, the deletion of cabling from
the audio board to the volume device radically shortens the
audio signal path and minimizes sound deterioration. As a result,
the C-02 now reproduce sounds that are perfectly suitable for
the name ‘reference model.’
* QVCS: Quad Volume Control System
Low Noise Operation
The control board for the entire ESOTERIC-QVCS is physically
separated from the audio circuit and also electrically isolated
using a photo coupler. The circuit design has also taken measures
to make sure that microcomputer noise is not introduced into the
audio path. This is accomplished by disabling the microcomputer
until a function is initiated by the user.
Low Rectifier Noise, Low Impedance,
High Response Power Circuit
(Five Transformers)
P R O U D LY M A D E I N T O K Y O
Five different transformers are used (one for each of the five
different power sources) - the input and the output amplifiers for
both the right and the left audio paths, and the control section –
combined with large capacitors make this extremely low
impedance and high response power circuit possible. For better
resolution and S/N ratio, the rectifier circuit incorporates the parts
and components a reference model deserves. As an example, the
use of SiC (silicon carbide) Schottky barrier diodes which have
higher speed and lower noise than normal Schottky barrier diodes.
ESOTERIC-HCLD (*)
ESOTERIC’s Own Output Buffer Circuit
with Fortified Current Transmission
Dramatically Enhances the Driving Performance
of the Power Amplifier
Looking at the subtleties of the signal transmission between
preamplifier and power amplifier, the ability of the component to
transfer current efficiency determines the overall quality of the
system. The preamplifier plays a significant role in this
relationship. Serving as a line driver, it should fully drive the
power amplifier to its maximum level to thoroughly convey
music signals that can include such a broad range of music
expression from pianissimo to fortissimo. What is required here
is high performance via high speed current transmission.
For the purpose of attaining the ultimate performance of the
C-02 as a line driver, the output buffer amplifier circuit uses high
quality materials and has its own board separate from the input
stage. The output buffer circuit provides the high current output
performance necessary. Its slew rate, representing response
speeds of 2,000 V/microsecond – is incredibly fast. Since this
buffer circuit is provided to each RCA output terminal and to the
hot and cold pins of the XLR output, the instant current supplied
gets maximized. The C-02 reenacts the breathtaking reality of
music whose dynamism tended to disappear in older systems
during smaller current transmissions between the preamplifier
and a power amplifier.

Extraordinary Usability
• Gain per input is widely adjustable with a precision of
+/-18 dB = 0.5 dB per step. This reduces volume variations
from source to source.
• Volume balance between the right and left channels is
adjustable with a precision of +/-6 dB = 0.5 dB per step.
• The output phase invert function allows an output that is
appropriate for the power amplifier used. In addition,
it is possible to individually determine a source-specific output
phase and to easily implement phase management
for the system.
• Unbalanced output (RCA), balanced output (XLR)
and RCA + XLR simultaneous output are the options.
• RCA-2 terminals are provided to switch between normal line
output and AV through output. This function allows you to
connect AV preamp to the C-02, sharing the same front
two-channel speakers (and its dedicated amplification system)
between music and surround movie applications.
• Source equipment names can be programmed into the system
using the remote controller.
• Display dimmer, mute, auto-display-off functions
are also available.
