An ultra-compact stereo power amplifier, powered by Hypex Ncore technology, designed to enable Bi-amping, or use in BTL (Bridge Tied Load/Bridged) mode.

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 of output power in stereo/bi-amp modes and 250W 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.

Latest Hypex Ncore amplifier technology, tuned by TEAC

The AP-505 employs a high-performance, energy-efficient Hypex Ncore power amplifier module which produces 130W + 130W in stereo/bi-amp modes or 250W in BTL mode. The module, which has undergone extensive listening tests before being carefully tuned and tweaked by our engineers, easily drives a wide range of speakers, delivering anything from a pianissimo to a fortissimo, and everything in between. In other words, it properly reproduces the dynamics of real music.

Not only for conventional stereo mode with 130W + 130W of output power, this compact unit also provides versatile speaker drive modes, Bi-amp and BTL modes by deploying a couple of AP-505 units side by side. The Bi-amp mode drives woofer and tweeter independently, while the BTL modes produces 250W of output power in each channel.

Full-metal, small footprint body for rigidity, stability and elegance

Every external panel – at the front, top and sides - is formed from high-grade aluminium alloy, firmly attached to the robust steel inner chassis. This method of construction helps reduce the transmission of mechanical vibration, ensuring that every single element inside the unit is allowed to perform at its best. Thanks to its convenient A4-sized footprint, the AP-505 easily slots into modern interiors where space-efficiency is important, such as on a desktop. This is in stark contrast to most conventional bi-amp/BTL-capable power amplifiers which are usually bulky, full-width units.
