  • Dual mono design throughout the system
  • Clean signal amplification with fully balanced input stage design
  • Two independent high capacity left/right spiral core power transformers
  • Discrete buffer amplifiers used in the input stage
  • Three easy-to-install support feet (patent numbers 4075477 and 3778108)
  • Two linked VU meters showing musical pulse, with four dimmer levels and two sensitivity settings
  • Fanless design to minimize noise
  • 12V trigger in and through for power sync

Dual mono design
With two spiral core power transformers and two Ncore modules, the deluxe circuit has a full dual mono structure from input to output. A dual mono structure, in which the channels are completely monophonic, prevents interference between the left and right signals and achieves excellent channel separation. This allows for rich sound reproduction that provides a larger sound stage and three-dimensional sound.

High efficiency with maximum 260 W + 260 W * 1 / 170 W + 170 W * 2
Hypex Ncore power amplifier modules achieve both high performance and high sound quality. These two amplifier units, which were specially tuned and designed for TEAC, drive the speakers without losing any of the original musical expression, from delicate pianissimo to powerful fortissimo.
*1 4Ω *2 8Ω

Vibration control
The front, side and back panels are fixed with 3mm thick heavy sheet metal as the main material. Joints that provide suspension are then used at the joints of the front, side, back and top panels. This enclosure with a flexible structure that controls the vibration of the entire device to enable live sound reproduction.

Fanless design is achieved with an efficient ventilation system
Despite the high efficiency of this power amplifier, a fanless design has been implemented by placing a circuit board that calculates the airflow through its inlet and outlet layout. Heat dissipation is increased by connecting the amplifier units directly to the bottom panel. Combined with the structure of the side panels, this reduces internal heat.

Extended design for vibration control
A floating construction keeps the transformers, which can easily cause vibrations, detached from the lower frame. The shape of the side panel fins, which provide heat dissipation, has also been tuned to eliminate vibration.

Other functions
  • Trigger input for power synchronization with other devices
  • Great VU meters
  • Switch meter dimmer
  • Toggle meter gain
  • Stereo/bi-amp switching
