Control/power amplifier developed by the design philosophy of "shortening a
signal course as much as possible."
The original volume control
technology DIGM (Digital Intelligent Gain Management) is adopted.
The class A switch using a bipolar transistor is used for this volume,
without dropping the level of an incoming signal,The gain of amplifier
is controlled by changing a metal film air register, and the quality of
amplifier is raised by carrying out the digital control of the gain of
Volume control is
66 steps at a time at 1dB.
Moreover, by using a DIGM function, the digital
balance regulating function is realized and balance adjustment on either side
can be adjusted to +10dB per dB.
CEC has adopted the new generation LEF
circuit (Load Effect Free) developed uniquely, and consists of pure Class-A
single ended amplifier.
All the circuits serve as a full balance design
from the input stage to the output stage. Furthermore, the music signal on
either side is suppressing the mutual intervention between each circuit by
processing in the independent circuit, respectively.
Since the loudness
level of sound of the sauce in which Output voltages differ is united, the
selection which raises a gain of 6dB for every input system is possible.
In order to maintain high power also to complicated load, eight 15A
power transistors are adopted.
The toroidal transformer of 300W combined
with the capacitor with a capacity of 90,000 micro F and the new LEF circuit is
adopted as a power-source part.
The case and the volume knob have adopted aluminum extrusion molding, and, in addition to high stability etc.,
have heightened the cooling effect.
Moreover, the heat sink arranged
immediately under top covering is united with a case, it passes cooling a heat
sink and the air inhaled from the upper part of the back is discharged by the
fan from the center of the bottom.
The internal temperature control
system was carried, the sensor has detected the internal temperature of
amplifier, and the air current in a cooling device is controlled automatically
to keep internal temperature suitable.
Volume, an input change, the core
temperature of amplifier, etc. are expressed as two VFD displays.
