Marketing description

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.

Product features

• Full-metal small footprint body for rigidity, stability and elegance
  Every external panel - at the front, top and sides - is formed from high-grade aluminum 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.
• Fully balanced design
  By employing a fully-balanced circuit design from the input section to the output stage, the AP-505 keeps the audio signal as unadulterated as possible as it moves through the amplifier, the result being extremely low distortion levels and an excellent signal-to-noise ratio (assisted by the effective elimination of common-mode noise).
• Carefully selected components exclusively designed for hi-fi applications
  At the input stage, where sound quality is fundamentally defined, high-quality MUSES8820E dual op-amps are employed for both the XLR and RCA inputs. In the power supply section for the input stage, both the left and right channel rectifying circuits are completely independent from the power transformer onwards, and employ four high-capacity 4700μF capacitors on each channel, achieving clear soundstage separation between channels. At the XLR input section, a well-designed circuit delivers excellent signal integrity, thanks in part to the elimination of coupling capacitors that can often lose audio information as a signal travels through them.
• 'Pin-Point' feet for easy installation
  The AP-505 employs TEAC's patent-pending 'Pin-Point' feet. These comprise two separated metal sections in an integrated housing. One has a spiked top and is attached to the bottom of the chassis, the other is a basin-shaped base that hangs down from the spiked section, with a flange-shaped cup to simplify installation. As a result of the unique design, the 'Pin-Point' feet considerably minimize vibrations and resonance, by virtue of the fact that the unit is supported on just three points, with a very small surface contact area. This arrangement reduces mid and low frequency muddiness so improving the soundstage and enhancing fine sonic detail.
• Passive cooling design for silent operation
  It makes no sense to design an amplifier that delivers excellent sound to a pair of speakers but which itself generates distracting operating noise from a cooling fan. From the outset TEAC engineers were determined to use a circuit and layout that would allow sufficient natural cooling, one that would allow the creation of a compact but powerful amplifier which didn't need the help of a cooling fan.
