The AP-701 stereo amplifier merges all of the elements desired in a power amp at a high level, creating a new standard.

Features

  • Two Ncore power modules made by Hypex Electronics B.V. And tuned especially for this model
  • High output with a practical maximum of 260 W + 260 W (4 Ω) / 170 W + 170 W (8 Ω)
  • Dual mono design throughout entire system
  • Clean signal amplification realized with a fully balanced design at the input stage
  • Two independent left/right high-capacity toroidal core power supply transformers
  • Discrete buffer amplifiers used in the input stage
  • Three supporting pinpoint feet that are easy to install (patent numbers 4075477 and 3778108)
  • Two linked VU meters which show musical pulse; with four dimmer levels and two sensitivity settings
  • Fan-free design to minimize noise
  • 12V trigger in and through for power synchronization

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.

High Output

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 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.

Perfectly-Sized to Fit Anywhere

A reduction in height, as well as the chassis depth, gives you more placement options. Whether in the living room or home office, you can use this power amp to drive your favorite speakers as you like.
