Advanced UHC-MOS Single Push-pull Circuit
The UHC-MOS FET is employed for the power amplifier output stage.
The steady current is 70 A and the instantaneous current is 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.
0
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 high current capacity, and a custom
block type capacitor that is tuned for high-quality sound.
0
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.
High performance
0
Equipped with a USB-DAC function to support playback of high-
resolution sound sources
This unit supports the playback of high resolution audio formats such as
DSD (2.8/5.6/11.2 MHz) and PCM files up to 384 kHz/32 bits. It
provides high quality playback of high resolution files into this unit from a
computer via USB-B connection.
0
DIGITAL AUDIO IN connectors (COAXIAL/OPTICAL)
You can play back PCM signals up to 192 kHz/24 bits by inputting digital
audio signals from an external device into this unit.
0
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.
0
External Pre-amplifier Input
A EXT.PRE IN (External Pre-amplifier 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.

This connection limits the effects of signal interference between the high range speakers (tweeters) and low range speakers (woofers), allowing you to
enjoy high quality playback.
When bi-wiring with bi-wireable speakers, connect the mid and high range terminals to SPEAKERS A (or SPEAKERS B), the low range terminals to
SPEAKERS B (or SPEAKERS A).

Connecting a playback device
You can connect turntables, tuners, CD players and network audio players to this unit.
If you set this unit’s input source to “PHONO” and you accidentally increase the volume without having a turntable connected, you may hear a hum noise
from the speakers.
NOTE
0
The earth terminal (SIGNAL GND) of this unit is not for safety grounding
purposes. If this terminal is connected when there is a lot of noise, the noise can
be reduced. Note that depending on the turntable, connecting the ground line may
have the reverse effect of increasing noise. In this case, it is not necessary to
connect the ground line.
0
The PHONO input terminals are equipped with a short pin-plug. Remove this plug
to connect a record player. Store the removed short pin-plug in a safe place so as
not to lose it.

Explanation of terms
DSD (Direct-Stream Digital)
One of the audio data recording methods, it is the signal aspect used to
store audio signals on a super audio CD, and is Δ-Σ modulated digital
audio. It is configured of an array of single bit values at a 2.8 MHz
sampling rate.
Sampling frequency
Sampling involves taking a reading of a sound wave (analog signal) at
regular intervals and expressing the height of the wave at each reading in
digitized format (producing a digital signal).
The number of readings taken in one second is called the “sampling
frequency”. The larger the value, the closer the reproduced sound is to the
original.
Linear PCM
This is an uncompressed PCM (Pulse Code Modulation) signal. This is the
same system used for CD audio but uses 192 kHz, 96 kHz, and 48 kHz
sampling frequencies on Blu-ray Disc or DVD and provides higher
resolution than CD.

Speaker impedance
This is an AC resistance value, indicated in Ω (ohms).
Greater power can be obtained when this value is smaller.
Source direct
Playback with higher fidelity to the source becomes possible, as input
audio signals are output by bypassing the audio quality-control circuits
(BASS/TREBLE/BALANCE).
Protection circuit
This is a function to prevent damage to devices within the power supply
when an abnormality such as an overload, excess voltage occurs or over
temperature for any reason.
If a malfunction occurs in this unit, the power indicator blinks red and the
unit switches to standby mode.
