TEAC announces an ultra-compact stereo power amplifier “AP-505” Powered by Hypex Ncore technology


TEAC Corporation (TOKYO:6803)(head office: Tama, Tokyo, President & CEO: Yuji Hanabusa) will release new Stereo Power Amplifier the AP-505.

Product Name Model Release Date
Power Amplifier AP-505 June 2019



The AP-505 is a versatile stereo power amplifier based around a high-performance, TEAC-tuned, Hypex Ncore power amplifier module, housed within a compact and elegant case.

Capable of operating in bi-amp and BTL (Bridge Tied Load/Bridged) modes, in addition to conventional stereo operation, the AP-505 produces a maximum 130W + 130W (@4Ω) of output power in stereo/bi-amp modes and 250W(@8Ω) in BTL/bridged mode. At its heart is an Ncore power amplifier module, made by Hypex of the Netherlands and specially tuned by TEAC's R&D team, for superlative sound quality.

As for the exterior, lightweight aluminum-alloy panels cover a robust steel chassis. A pair of large level meters add visual interest when the amplifier is in action, while TEAC's patent-pending ‘Pin-point’ feet, located at three strategic positions on the underside, add incision to the sound, helping to create a more detailed and stable stereo image.
