AP701B
Dual mono power amplifier with fully balanced structure
and two custom-made Hypex Electronics Ncore power amplifier modules.
The unconstrained dynamics of sound awakens fundamental instincts. The NEW AP-701 merges all of the elements desired in a power amplifier at a high level, creating a new standard.
Independent left/right high-capacity toroidal core power supply transformers, discrete buffer amplifiers and two Ncore modules provide a complete dual-mono structure from input to output.
Moreover, the input stage of each channel has a fully balanced design, so the dynamism of input signals is amplified as is, maximizing the innate performance of the speakers.
The cabinet is primarily comprised of 3mm-thick heavy metal plate but has flexible structure to control vibration.
By incorporating joints with suspension functions, the vibration frequency of the entire device is controlled to reproduce open and vibrant sound.
Complete dual mono design includes power supply
With two toroidal core power supply transformers and two Ncore modules, the extravagant circuitry has a complete dual mono structure from input to output. A dual mono structure, in which the channels are each completely mono, prevents interference between the left and right signals and achieves outstanding channel separation. This enables rich audio reproduction that provides a larger sound stage and more three dimensional sound.
High output with a practical maximum of 260 W + 260 W*1 / 170 W + 170 W*2
Hypex Ncore power amplifier modules realize both high efficiency and high audio quality. These two amplifier modules, which were tuned and designed specifically for TEAC, drive the speakers without losing any of the original musical expression, from delicate pianissimo to powerful fortissimo.

Vibration control from flexible structure
The front, side and rear panels are secured with 3mm-thick heavy sheet metal as the primary material. Then, joints that provide suspension are used at the junctures of the front, side, rear and top panels. This enclosure with a flexible structure controls the vibration of the entire device to allow open and vibrant sound reproduction.
Fan-free design achieved with effective ventilation system
Despite the high output of this power amplifier, a fan-free design has been realized with circuit board placement calculated for airflow and precise layout of air inlets and outlets. Heat dispersion is increased by attaching the amplifier modules directly to the bottom panel. Along with the fin structure of the side panels, this reliably abates internal heat.
Extensive design for vibration control
A floating structure keeps the transformers, which can easily cause vibration, detached from the bottom panel. The form of the side panel fins, which provide heat dispersion, have been adjusted to eliminate vibration.
In order to suppress vibrations that affect audio quality thoroughly, the TEAC original pin-point feet that utlize a new mechanism are attached to the bottom panel with appropriate allowance, while a number of screws that fix the circuit boards to the chassis is minimized.
Numerous features for audio quality
The durability of input circuits is ensured by including slits between each connector. In addition, direct wiring without connectors is used from the input circuits to deliver input signals to the discrete buffer circuits without losing any of their clarity.
Low-profile body creates new potential in living spaces
A reduction in height, as well as the chassis depth, enables more freedom of placement. Whether in the living room or a workplace, you can use them to drive your favorite speakers as you like.
