The head section is equipped with a combination of three heads for independent recording
and playback, enabling high-performance recording by optimizing the recording and
playback process, including the amplifier section.
The head adopts a PCOCC winding CA head.
This head uses CA (cobalt amorphous) as the core, which achieves both the ideal of a head
core with high electromagnetic conversion efficiency, accurate recording and playback of
micro signals, and resistance to wear. In addition, by taking advantage of the
non-crystalline amorphous structure, the core is laminated into 14 layers to increase
electromagnetic transmittance, reduce eddy current losses, and further improve
high-frequency characteristics.
In addition, in order to reduce micro-level signal distortion and transmission loss, 99.997%
PCOCC (single crystal high-purity oxygen-free copper), a high-efficiency transmission material,
is used for the internal winding.
The head block is supported by a zinc alloy die-cast head base.
Unlike ordinary metal plates, the high mass prevents minute vibrations from being transmitted
to the head. In addition, due to its excellent durability such as temperature changes, it always
maintains accurate head position and azimus angle, and has the reliability to maintain
excellent high-frequency and phase characteristics over a long period of time.
The mechanism adopts a closed-loop dual-capstan system.
In this system, two sets of capstan and pinch rollers on both sides of the head keep the
tape tension constant from the beginning to the end of the winding, and the stable head
touch isolates harmful micro-vibrations transmitted to the tape.
This mechanism has been further brushed up, and the frequency distribution of the pinch
roller diameter is slightly different from the left and right poles, so that the effects of periodic
fluctuations in rotation are mutually canceled. The capstan surface is also etched on the order
of sub-microns, which greatly increases the grip of the tape and prevents slipping.
The capstan motor shaft is equipped with a high-precision large flywheel to increase the
inertial mass to reduce the occurrence of rotational unevenness.
It uses an anti-static cassette stabilizer, which strongly crimps the entire cassette half to the
holder head to thoroughly suppress vibration. Combined with a rigid cassette holder and
a triangle cassette support system, it suppresses the resonance of the mechanism system.
The stabilizer part adopts TEAC's unique anti-static structure.
A special highly conductive pad on the half-crimped part emits static electricity, which
greatly reduces the occurrence of problems.
The cassette holder part adopts a triangle cassette support system.
In this method, three protrusions are provided on the holder part, and the tape support is
less rattling than the conventional 4-point support method.
In addition, special vibration damping rubber is added to the holder bed and the half is
crimped from both sides to achieve a more thorough vibration isolation structure.
The cassette lid is made of aluminum material weighing 200 g and 6 mm thick, making the
entire holder part more massive.
In addition, the resin holder part is five times stronger than conventional materials, and is made
of a special polymer material with large internal losses and excellent vibration damping
properties, and is integrated with a 1.6mm thick steel plate to strengthen it.
The front panel is made of 5mm thick solid aluminum.
The internal structure adopts a separate block structure.
In this method, the running mechanism, amplifier system, running system, and power supply
section are completely separated by an internal frame, and the volume, mechanism,
and display parts are also fully shielded to eliminate mutual interference between circuits.
The chassis structure adopts a high-rigid chassis.
The main body is installed on the bottom chassis that supports the bottom, and the side chassis
on both sides and the two internal frames connecting the front and rear are rigidly constructed.
In addition, the inverted U-shaped top panel is firmly integrated with these frames with 10
screws, which gives it a high degree of rigidity.
In particular, the two internal frames are a kind of beam structure, which strengthens the
whole body.
The tape running mechanism part is fixed to the mechanism-only chassis, which is independent
of the bottom chassis.
This significantly increases rigidity by forming a double structure with the bottom chassis,
blocking external vibrations and suppressing the transmission of micro-vibrations inherent in
the mechanism to the interior.
To achieve the 3S (Soft, Smooth, Silent) tradition of TEAC, we use a three-motor system and
a power load/ejection system that efficiently controls each section of the capstan, reel, and mechanism.
The recording volume control adopts a master volume + L/R balanced volume configuration
to enhance the operability. In addition, level fluctuations and phase changes due to
volume position are greatly suppressed.
In addition, it is equipped with an ultra-precise custom-made unit of measuring instrument
grade, and by inserting resistors and other high-quality parts, it is highly accurate to link with
the memory display value from ∞ to 0dB, enabling precise control.
In addition, the knob adopts high-grade specifications of machined aluminum.
It is equipped with Dolby S as a noise reduction system.
This method is based on the Dolby B/C and introduces the principle of Dolby SR for
professional use, and achieves a noise reduction effect of 24 dB in the high frequencies and
10 dB in the low frequencies.
In addition, high-precision signal processing technology suppresses the breathing
phenomenon unique to NR systems.
The recording margin is expanded by setting the recording standard level of Dolby B/C/S NR
to DIN 250 nWb/m.
In addition, the 150 kHz high-bias recording circuit suppresses interference with high-frequency
signals and prevents characteristic degradation.
It is equipped with a Dolby HX Pro that improves high-frequency recording characteristics.
The regenerative amplifier adopts a full-stage mono all-DC configuration with a two-power
direct coupling system.
In addition, the head amplifier section has a DC configuration that eliminates input
coupling capacitors to improve low-frequency noise, phase characteristics, and linearity.
It is equipped with a left-right independent calibration mechanism that can be fine-tuned
to the optimal bias value and level (sensitivity) of the tape.
This feature automatically switches the meter scale and can be precisely adjusted by means
of the built-in oscillator.
The power supply is equipped with a large transformer and a large electrolytic capacitor to
ensure a stable and spacious supply.
In addition, the mechanism system and the recording and playback amplifier system are
completely separated from the windings, making it possible to supply power with minimal
mutual interference.
It has a wide-scale (-40dB~+10dB) peak level meter.
In addition, it uses a high-precision linear time tape counter that displays the tape running
fee in time.
The display ON/OFF switch is installed on the remote control.
It adopts an OFC power cord with polarity indication.
It is equipped with a CD direct input, allowing for purer recordings directly connected to the input.
It is equipped with a CPS automatic song selection function (15 songs) that allows you to head
out like a CD player.

you can specify Stop, Play or Play-Pause.
It is equipped with a CD level check function that can be used to set the recording level.
