Features of This ProductFeature 1: Complete Separation of the Right and Left GND Channels

We have applied the complete GND separation technology incorporated in the P-3 preamplifier to A-3 thathas a power amplifier circuit. Originally, how to ground the GND of a power amplifier that handles high current
to the chassis was a key design issue, and there was no precedent for ungrounded GND. However, theungrounding of the power amplifier’s enclosure was achieved through the simple non-NFB circuit, optimized
artwork design, minimization of high current loops, elimination of inductance components, and other factors.
This led to the birth of the integrated amplifier A-3 featuring completely separated left and right GNDs.
Furthermore, by separating the control signals of the selector, volume, protection circuit, and other relays witha photocoupler, we achieved complete GND separation that takes capacitance and inductive components into
consideration. The three-dimensional sound field space and spaciousness are the new frontiers of integrated
amplifiers.

Feature 2: Single Push-pull Output StageFor the output stage, we have adopted the single push-pull SEPP circuit using the TO-3 (metal can type)bipolar transistor that is used in M-3. It can play blur-free music at the correct timing, supporting from ultra-low
to ultra-high frequencies. The heart-stirring music playback is achieved by single push-pull which does not
spoil micro-time axis accuracy.

Feature 3: Four-stage Darlington Configuration with Super-powerful Driver and Pre-driver

To drive the TO-3 (metal can type) transistor easily, ultra-powerful TO-3P transistors are used in the driver aswell as in the pre-driver. Ensuring perfect current supply all the way to the bottom end without regard to hfe
fluctuation at high currents makes it possible to achieve deeply expressive and groovy sounds.

Feature 4: New Type-R Circuit Adopted

For voltage amplification, we have newly developed the high-gain-to-GND single-stage Type-R amplification
circuit. Naked foil resistors are used generously for all resistors that are involved in amplifier operation.

Feature 5: GND Switching Selector

The selector that disconnects the connection up to GNDs was an important part of P-3. This is also adopted
in A-3. It eliminates sound quality degradation caused by GND loops that occur when many playback devices
are connected. The RSR custom relay, being the highest grade relay, is adopted as the relay.

Feature 6: Resistor-switching Volume

We have adopted the resistor-switching balanced volume which is the simplest control method and is least
likely to decrease freshness of the sound source. Of course, RSR custom relays and naked foil resistors areused throughout this design. This is the highest-grade volume conceivable.

Feature 7: GND Anchor

The GND in the left and right channel power supply units is grounded to the left/right-side metal that is insulated
by ceramic washers. We have adopted a special enclosure structure that serves as a GND anchor. A sense of
openness and low-end grip are achieved at a high level.

Feature 8: Super-strong Power Transformer

Two 700VA unimpregnated toroidal power transformers are used on the left and right for the power amplification.
In addition, three power transformers, including the control system power transformer, are packed into one
enclosure. They are all mounted vertically so that the magnetic field lines are parallel to the board.

12

Feature 9: High-speed non-NFB Power Supply

For the rectifying capacitor, we have adopted a specially-selected low magnification foil filter capacitor of only
470uF featuring high-withstand voltage and low capacitance. We have adjusted the number of the capacitors to
be used in order to optimize the capacitance, thereby reducing the load on the power transformer. This further
improves real regulation of the ultra-powerful power transformer. For the rectifier diodes, we have adopted SiC
diodes of the latest specifications with enhanced allowable inrush current. This is the most powerful and highspeed power supply configuration conceivable. In addition, two unsecured large power relays with excellent
sound quality are used independently as power switches for the two main power transformers. In other words,
the Power Switch on the front panel is dedicated to the control system sub-transformer. Having an independent
power switch for each power transformer, which is a high current contact point, is extremely crucial for soundquality.

Feature 10: Heat Sink That Also Serves as Copper Bus Bar

Lightweight, small copper plates are used for the main heat sink. This heat sink also serves as a bus barthat supplies power to the TO-3 (metal can type) transistor, and the terminals of the TO-3 (metal can type)transistor penetrate the bus bar and are connected directly to the board underneath. Thus, we eliminatedwiring which is a drawback of the TO-3 (metal can type) transistor to overcome instability caused by the
inductance component while eliminating sound quality degradation that is caused by insulation sheet damping
on the device. The physical independence of the heat sink from the chassis also has a profound effect on thesound quality, creating a sense of freedom and transparency. Furthermore, in A-3, the power supply board andamplifier board are connected by a bus bar heat sink which also serves as a structural component to form ablock. It is truly a “four birds with one stone” heat sink.

Feature 11: Unsecured Structure

The amplifier block, terminals, AC inlet, top cover, and bottom cover are all unsecured. We especially focusedon the amplifier block by adopting the three-point lateral sliding structure using titanium sliders. While escaping
from the harmful vibration of the power transformer, it also releases its own intrinsic vibration.

Feature 12: Volume Bypass Feature

For an XLR system and an RCA system, volume bypass can be set by fixing the gain at 22dB. By connecting
the output of an AV preamplifier, it can be used as an AV power amplifier.

Feature 13: Multiple-unit Connection Feature

Using a 3.5Φ stereo mini-plug cable, multiple units can be linked (simultaneous control of volume and otherfeatures is possible). By setting a leader and followers, all followers can follow the state of the leader. In
addition, the follower can differentiate between the leader’s and the follower’s volume. This function enables,for example, volume control in a multi-amp configuration with digital channel dividers after DA conversion. Of
course, the floating GND of the control system eliminates problems such as GND loops caused by coupling.

Feature 14: REC OUT Feature

REC IN/REC OUT terminals are provided to connect an open reel deck or a digital recorder. For these terminals,
you can use XLR or RCA cables.

Protection Pads for Transport

About Installation

When unboxing this product, be sure to remove thetransport cushions. With the cushions left attached,
the intended sound quality of this product cannot be
fully enjoyed.

When this product is installed on your shelf or audiorack with the spike pins attached, the supplied spikereceiving board can protect the installation surface
from scratching.
Using the setting spacers along with the spikereceiving board ensures that there is space between
the installation surface and the spike-receiving board.
With that space, the air hole of the spike-receiving
board can be utilized. This can further improve thesound quality.
The setting spacers can also be used alone as spikereceivers.
