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 drives a wide range of speakers, delivering a mean pianissimo, fortissimo and everything in between. In other words, it properly reproduces the dynamics of real music.
Stability and Elegance
The front, top and side panels are made from high-grade aluminum alloy and firmly attached to the robust steel inner chassis. This method of construction helps reduce the transmission of mechanical vibration and ensures that every single element inside the unit performs at its best. Thanks to its convenient A4-size, the AP-505 is very space-efficient and easily fits into modern interiors. This is in stark contrast to most conventional bi-amp/BTL-capable power amplifiers, which are usually bulky, full-width units.
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
The amplifier employs high-quality MUSES8820E dual op-amps 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 and use four high-capacity, 4700μF capacitors on each channel (8 in total), achieving clear soundstage separation between channels. 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.
Toroidal Power Transformer
The AP-505 employs a high capacity toroidal-core transformer with Schottky barrier diodes in the rectifying circuit. Unlike conventional diodes, Schottky barrier diodes reduce rectifier noise, leading to a cleaner supply and a more stable current delivery.
