TEAC Reference700 Series 2000x1000


Ap 701 b interior

Complete dual-mono design including 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.

N core logo

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.

Ap 701 chassis

Vibration control from a 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 with an 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.

Vibration control design

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 utilize a new mechanism are attached to the bottom panel with appropriate allowance, while a number of screws fix the circuit boards to the chassis is minimized.

High-Performance Audio Quality

Slits are cut between each connector to ensure input circuit durability. In addition, direct wiring without connectors is used from the input circuits to deliver signals to the discrete buffer circuits without losing any of their clarity.
