Control amplifier announced as a flag ship model of
The dual chassis as which C100 was adopted is inherited, an
analog circuit is concentrated on a lower chassis, and the power supply system
and the control system have composition stored on a top chassis.
composition separated the analog circuit from the noise of a power source or a
control system, and the cross interferencee is eliminated.
The full balance circuit is carried and all the stages until it results
in an input - an output have balance composition.
Moreover, not only in an amplifier
circuitry but an input switchover, volume control, etc., each channel arranges
the component to which the property was equal at + and - side.
individual power circuit is installed in each amplifier part, and it has become a double product line from each power source to the signal circuit.
connection of the monolithic ceramic condenser is carried out to the
electric-field capacitor of the power source, and the decoupling of the power
source is ensured over the audio band and RF spectrum.
Moreover, the double
shielding by copper and iron was adopted as the power transformer, and it has
prevented the noise resulting from a transformer mixing in a signal.
After plating a relay switchpoint with gold, the high-definition relay
with the contact plated with the ruthenium made into the highest as a rhodium
and a contact material is adopted as it. Furthermore, enclosure of inert gas
prevents a contact from corroding, and the robustness is improved.
The phone equalizer circuitry is carried.
In this circuitry, gain of the open loop is made into high level, and the Low-noise-izing is attained by suitable NF circuitry.
Moreover, the input transformer only
for MC cartridge is carried, a silver wire is used for a coil, and it is stored
by the independent mu factor metal shielding.
It is possible to carry
the input level matching functionality, to set the volume for every input as
memory, and to arrange each level.
A balance stream composition is put
into practice also in the volume control stage, and the high precision
logarithmic attenuator section by a total of four microprocessor controls of a
right-and-left channel is respectively installed in + and - side,The common
noise, the distorted removal, and the exact tracking precision were attained, and 213 steps of a 0.5dB unit of measure are realized with an error of ±0.05dB
Furthermore, taking advantage of the merit of a processor control,
it is selectable about three control patterns, and the whole dynamic range is
covered with two rotations, and it covers with Fast by one rotation at Slow. And
in VRV, a volume curve equal to the usual volume potention meter is drawn.
Moreover, there are the two modes also in a balance control, one it1 is
equivalent to 1dB, and there are Slow of the 1dB step which turns a knob slowly, and Fast which turns quickly and obtains a big transition.
The balance amplifier of a discrete is behind the volume control stage, and each pair is
driving the balance output on either side.
The setup menu facility is
carried and it is the intensity control of a display device,The source trim
which arranges a full word or a compaction window, and each input level for the
selection source, source turning on and off which skips an input selection, a
volume control mode selection, a balance control mode selection, a control pass
through, and remote control mode selection are possible.
The control-pass-through circuitry is carried and the audio signal of each
front right and left from a home theater processor carries out through
of C200 as it is.
The extra audio output for two or more amplifier speakers is
The control jack in which power on/off of power amplifier etc.
is possible is carried from C200.
The muting circuit which cancels the
noise at the time of on/off is carried.
Input / output connector has adopted gilding.
When the reset function is carried and the lockup of the microprocessor
is carried out, it will be reset if it continues pushing a red power button 2
seconds or more.
When the rocker switch is carried and it does not use a
system for a long period of time, the value proofread to non-volatile memory is
The multifunctional remote control which can be used also
for the compact disk player and FM/AM tuner made from a mac is attached.
