Cautions on handling
Advanced UHC-MOS Single Push-pull Circuit
The new generation UHC-MOS FET is employed for the power
amplifier output stage.
The steady current is scaled up from 30 A to 70 A and the
instantaneous current from 120 A to 210 A.
The operation stability affected by the temperature fluctuation is
improved by using the dual FET selected first stage for the voltage
amplifier stage. Furthermore, the phase property is stabilized up to
the high range by using the cascade bootstrap circuit.
Power Supply
To make the most of the Advanced UHC-MOS Single Push–pull
Circuit, this powerful power supply consists of a LC mount twin
transformer, schottky barrier diodes that have 50% more current
capacity compared to the conventional ones, and a custom block
type capacitor that is tuned for high-quality sound.
Flat Amp
A FET output flat amplifier of a full discrete configuration that
has a high-quality local stabilizer power supply is included in the
preamplifier section.
Phono Equalizer
Even a user who is particular about analog records is satisfied
because the Phono Equalizer circuit for the FET input supports
MM/MC.
Power Amp Direct
A Power Amp Direct input that can also be used for a standalone
power amplifier is equipped, useful for combining with the audio
system and home theater system, etc.
Pre Out
A Pre Out connector is equipped that can extend the system’s
possibility by using another power amplifier to drive a bi-amplifier
with a speaker that supports the bi-wiring or adding a subwoofer
to upgrade the system.
Mechanical Ground
A chassis that has 6 discrete blocks shielded for each signal level
and a foot made of high density materials pursue the Mechanical
Ground concept, eliminating the influences caused by external
vibration and preventing vibration of the transformer, the internal
vibration source, from being transmitted to the amplifier circuit.
•Before turning the power on
Check once again that all connections are correct and that there are
no problems with the connection cables.
•Power is supplied to some of the circuitry even when the unit is
set to the standby mode. When going on vacation or leaving home
for long periods of time, be sure to unplug the power cord from the
power outlet.
•About condensation
If there is a major difference in temperature between the inside of
the unit and the surroundings, condensation (dew) may form on
the operating parts inside the unit, causing the unit not to operate
properly.
If this happens, let the unit sit for an hour or two with the power
turned off and wait until there is little difference in temperature
before using the unit.
•Cautions on using mobile phones
Using a mobile phone near this unit may result in noise. If that
occurs, move the mobile phone away from this unit when it is in use.
•Moving the unit
Turn off the power and unplug the power cord from the power
outlet. Next, disconnect the connection cables to other system units
before moving the unit.
•About care
•Wipe the cabinet and control panel clean with a soft cloth.
•Follow the instructions when using a chemical cleaner.
•Benzene, paint thinner or other organic solvents as well as
insecticide may cause material changes and discoloration if brought
into contact with the unit, and should therefore not be used.

v See overleaf
Connections for all compatible audio signal format is described in
this operating instructions. Please select the types of connections
corresponding to the equipment you are connecting.
NOTE
•Do not plug in the power cord until all connections have been
completed.
•When making connections, also refer to the operating instructions of
the other components.
•Be sure to connect the left and right channels properly (left with left,
right with right).
•Do not bundle power cords with connection cables. Doing so can
result in humming or noise.
•Do not turn up the volume without a turntable connected to the
PHONO input terminals. Doing so will cause humming or noise.
n Cautions on playing SA sources:
When regular speakers not compatible with SA sources (DVD
Audio discs, Super Audio CDs and other sources, including
treble components above the audible range), set the properties
of the player (DVD Audio player, Super Audio CD player, etc.)
for use with regular speakers (or amplifiers).
The speakers may be damaged if the volume is set too high
when playing SA sources. For instructions on player settings,
refer to the operating instructions included with the player.
Cables used for connections

Connecting the speakers cables
Carefully check the left (L) and right (R) channels and + (red) and –
(black) polarities on the speakers being connected to the unit, and be
sure to connect the channels and polarities correctly.
Peel off about 10 mm of sheathing

from the tip of the speaker cable, then
either twist the core wire tightly or
apply solder to it.
Turn the speaker terminal

counterclockwise to loosen it.
Insert the speaker cable’s core wire to

NOTE
•Connect the speaker cables so they do not stick out of the speaker
terminals. The protection circuit may be activated if the wires touch
the rear panel or if the + and – sides touch each other (vpage5
“Protection circuit”).
•Never touch the speaker terminals while the power supply is
connected. Doing so could result in electric shock.
