Enjoy incredible purity of sound and power efficiency with the AP701 Stereo Power Amplifier in black from TEAC. The AP701 employs a fully-balanced dual-mono structure from input to output, preventing interference between the left and right signals to achieve outstanding channel separation. It features two custom Hypex Ncore power modules, powered by independent toroidal transformers, delivering 125W RMS power at 8 Ohms or 230W RMS at 4 Ohms. The chassis, feet, and internal build structure are designed to minimize or eliminate all vibration and the fan-free ventilation system further reduces any unwanted noise. For the ultimate hi-fi setup, combine two AP701s in bi-amp mode to separately amplify high and low as well as left and right.
Complete Dual-Mono Design Including Power Supply
With two toroidal core power supply transformers and two Ncore amplifier modules, the extravagant circuitry has a complete dual-mono structure from input to output. This structure, in which the left and right channels are each completely mono, prevents interference between the 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 170W per Channel at 8 Ohms
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. NCORE technology combines the stability of Universal class-D amplifiers with improved load-independence, lower distortion, and lower output impedance which amounts to a performance that can be classified as 10 times better than its predecessor.
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.
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 are attached to the bottom panel with appropriate allowance, while the number of screws that fix the circuit boards to the chassis are minimized.
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.
