TEAC AX505B Reference 500 Series Integrated Amplifier – Black

The AX505B is a stereo integrated amplifier with an A4-size footprint that produces 115W + 115W of output power.

We used a cool-running, energy-efficient TEAC tuned Ncore module by Dutch company Hypex in the power amplifier portion. Hi-Res audio information is reproduced with authentic energy and musical passion by its crystal-clear audio with low distortion and high Signalto-Noise ratio. The AX505B also features an integrated headphone amplifier that enables “ground independent” connections, enabling high-quality headphone listening. A pair of eye-catching level metres on the front panel track musical volume levels as they ebb and flow but they are admittedly more “eye candy” than a practical requirement. The presence of a well-damped volume control finished with a machined aluminium knob for precise volume adjustment further improves the user experience. The listener may concentrate on their music without being distracted by annoying fan noise thanks to a passive-cooling design that ensures absolutely silent operation.

You can enjoy all the advantages of high-end, Hi-Res audio, including DSD512 and PCM 768kHz content when you pair this cutting-edge stereo integrated amplifier with either the UD-505 or the NT-505 USB DAC/Network Player from TEAC.

Hypex’s Ncore Power Amplifier, Which TEAC Custom-Tuned

The Hypex Ncore power amplifier module at the heart of the AX505B’s exceptional performance and energy efficiency produces 115W+ 115W of output power from a compact unit. This isn’t your typical Ncore module; TEAC has painstakingly optimised it to offer the most musical expressiveness possible across the whole musical canon.

Parts That Have Been Carefully Chosen And Specifically Created For Hi-Fi Applications

Our experts carefully selected all essential parts from “built for hi-fi” ranges whenever feasible, starting with MUSE op-amps in the analogue section, which basically affects the amplifier’s sound quality.

Balanced XLR Inputs

The AX505B features two XLR balanced analogue audio inputs to lessen the amount of background noise that is picked up while an analogue audio signal goes down the connected line.

Circuit For A CCLC Headphone Amplifier For Optimal Linearity

The 4-pole headphone output jack of the AX505B additionally enables a “ground-separate” connection for optimal channel separation when using headphones. While coupling condensers are not used in the output stage of the CCLC (Coupling Capacitor-less Circuit) headphone amplifier circuit design. With less sonic coloration introduced during processing, your headphones will receive a more genuine audio signal.

A Power Transformer With A Toroidal Core And High Capacity

The AX505B uses Schottky barrier diodes in the rectifying circuit and a high capacity toroidal-core power transformer in the power supply section. Schottky barrier diodes have a benefit over conventional varieties in that they provide cleaner and more stable current, which lowers rectifier noise across the entire amplifier’s circuitry.

Design With Passive Cooling For Silent Operation

It is absurd for an amplifier to produce unnecessary operating noise from a cooling fan while providing outstanding sound to loudspeakers. Because of this, our engineers gave the AX505B’s circuit and cabinet design extra thought. They arranged the parts in a way that would allow for the natural removal of heat, resulting in a small but powerful amplifier that doesn’t need a cooling fan.

Full-Metal Construction For Rigour, Sturdiness, And Elegance

The top and side panels are fastened to the sturdy steel inner chassis in the same manner that the front panel is. Heavy parts used in this construction’s high standard aid in reducing mechanical vibration. The AX505B is a little device with an A4-sized footprint that easily fits into even the smallest of contemporary areas.

There Are Many Inputs For Optimum Adaptability

To enable the usage of interconnects with large plugs, connections are placed on the rear panel with a large pitch between them. Even if you initially use the AX505B as part of a pretty basic desktop PC audio setup, the three sets of RCA analogue inputs provide you the option to build a full-scale hi-fi system. Additionally, theAX505B has a set of screw-type speaker terminals with a wide pitch and diagonal offsets for simple wiring that can take high-grade AWG8 gauge cables and banana plugs.

An Intuitive Design For Simplicity Of Use

The AX505B utilises a conventional toggle to turn the amplifier on and off while using a volume control with a machined aluminium knob for accurate volume control in order to deliver a more tactile response. You may adjust volume in 0.5dB steps at moderate volumes with the remote control, which is topped with a stylish aluminium cover.

Dual Level Metres That Keep Tabs On Your Music’s Tempo

As volume levels vary, a pair of level metres that dance in rhythm with the music help give your music a visual dimension while reinforcing the amplifier’s significant aesthetic appeal. Depending on preference, a 4-step dimmer with the ability to turn off the metres or emphasise movement even more (by raising sensitivity by +20dB) can be used. By observing the position of the toggle-type power switch, you may identify whether the device is turned on or off from a distance even when the level metres are disabled and the lighting is off.
