Ever since its beginning, Accuphase has been researching
and accumulating considerable expertise in the domain ofanalog records. The C-27 in 2008 and the C-37 in 2014 are
the fruits of labor at that time.
But now, the new C-47 is moving on to another level with a
MC cartridge-dedicated balance input, it realizes the balance
connection with the analog record player.
In this balanced connection, applying the latest Accuphasetechnologies, the entire path for the signals from input
connectors to the output is a fully balanced construction.
Together with the C-47, which made a great deal of progresswith the latest noise reduction technologies, and fully
expresses what’s great about any phono cartridges, enjoy
the new discovery and impressions of analog disc playback.

It brings an elegant atmosphere with natural wood grain
finished side panels.
**The former model C-37 used the velvet-coated iron plate .
The numeric display for Load impedance is newly added.
**No numeric display in C-37

In MC connection, the 200Ω setting is newly added.
**3Ω setting is deleted.

C-47 has a MC type cartridge-dedicated balanced input, and
3 of pairs of line input connectors.
It can memorize each input’s individual function settings.

3Complete separation design with individual toroidal powertransformer and all circuit boards from power supply circuit toequalizer amplifier circuit for left and right channel.
Amplifier circuits are mounted on glass fluorocarbon PCboard.
C-47 is equipped with Low flux leakage & high-capacity
toroidal transformers and ultra low noise power supply
circuits consisting of 8 electrolytic capacitors of 15000μFcapacity.

4C-47 applies the latest technologies which are used in C3850 or E-800 for ultra low noise characteristics, and realizes
the fully balanced constructions. Also, the instrumentation
amplifier topology contributes achieving the fully balanced
input at both MC/MM connections.
The head amps are optimized with depending on the type ofcartridge, this also helps to show the ultra low noise
performance.

5The signal paths among the circuits are shortened as muchas possible and all amplifiers located on the same PC-Board
brings out the best electrical performance and sound quality.
The PC-Boards are glass fluorocarbon substrate which isexcellent in the high-frequency characteristics and the heatresistance.

C-47 shows astonishing low noise and THD(Total HarmonicDistortion) characteristics.
This performance can be said to be a World-Champion-Classquality.

C-47 guarantees RIAA deviation only ±0.3dB with selected
high-precise capacitors and resistors.

The most of MM type cartridges have static shield at power
generator, and the static shield is connected to the negative
polarity side of either channel.
If MM type cartridges are set to the balanced connections,
The noise amount at positive polarity side and negative
polarity side inside the cartridge is varied.
The noise cancelling effect at balanced input amp cannot be
occurred, therefore MM’s Balanced connection is opened tothe noise influence rather than line connection.
