Teac A-H01 Integrated Amplifier & USB DAC - Black
HK$ 3,063.00

Experience unparalleled sound straight from your computer. Compact High-Performance/High-Output Amplifier The amplifier circuitry uses the 50Asx2 by Bang & Olufsen ICEpower of Denmark. High efficiency conversion allows compact dimensions despite high-output (60W + 60W) – power comparable to full-size amplifiers. Energy efficient design minimizes power consumption (34W) compared to the approximately 85W consumed by conventional products (45W + 45W). Expandability and Input/Output Connector Options Belying it's Compact Dimensions Despite its compact dimensions, the A-H01 offers the full range of connection outputs a listener would except of an amplifier designed for use in PC-based audio setups, including two digital inputs (one coaxial and one optical) and two analog inputs, in addition to a USB port (for connecting to a Pc). The speaker connections are large binding post accommodating cables up to Awg8. The speaker connectors also support Banana plugs and a subwoofer pre-out terminal. A headphone jack lets users enjoy audio late at night, in spaces with neighbors close by or other situations where speaker playback might disturb others. Built-in Burr-Brown Pcm5102 DAC for a High Performance and a Broad Range of Digital Audio Sources The A-H01 uses a Burr-Brown Pcm5102 Dac. After installing the appropriate driver, listeners simply connect a Windows or Mac computer via a USB cable to ensure a digital signal path all the way to the Dac, transforming the iTunes or other media players into high quality audio devices. The A-H01's specifications will satisfy even the most fastidious of audiophiles, including support for audio sources of up to 24bit/192kHz and asynchronous Usb. High-Performance Components that Measure up to Full-Size Amplifiers A-H01 incorporates a motor-driven volume knob and an aluminum front panel. Other components, including the large binding post speaker terminals and 3-pin power socket, are the same size as those found on full-size amplifiers. These design decisions ensure ease of use and secure connections, they also suggest the no-compromise approach taken in designing this compact audio unit. Fan-Less Design for Refined Quietness Efforts to eliminate signal noise for high-quality audio playback mean nothing with a noisy amplifier fan. To achieve the dual goals of high performance and compact dimensions – two parameters that conflict with efficient heat dissipation – circuit design and chassis design emphasized the selection and effective placement of potential heat-generating components to allow this high-performance compact amplifier to operate without cooling fans.

Once the driver software is installed, your playlist iTunes or Windows Media Player turns into part of your high-quality audio system. This allows 24bit/192kHz data transfer mode reduces jitter noise while the digital data travels along the USB cable. BurrBrown Pcm5102 D/A Converter for a Variety of Digital Sources The Ai-501Da employs the highly celebrated BurrBrown Pcm5102, allowing 32bit processing across the USB audio input, Optical and Coaxial digital inputs. Parts were carefully selected for the analog circuits. The unit utilizes high-quality operational-amplifiers and electrolytic capacitors already proven on previous hig-end models. Large Capacity Toroidal-Core Power Transformer An over-sized Troidal-core power transformer helps deliver high-quality sound without sacrificing energy-efficiency and the unit’s compact imentions. Conventional diodes produce rectification noise that negatively affects the sound of other units. To combat this, Teac installed Schottky Barrier Diodes to supply a cleaner internal current and reduce rectification noise High-Quality Headphone Output Processed by an Exclusive Operational Amplifier on Each Channel The Ai-501Da is also designed for headphone listening, as well as speaker listening. An exclusive operational amplifier is employed on each channel. Conventional hi-fi systems only use a single operational amplifier for both channels. A Full-Metal Construction and Small Footprint for Any Desktop Set-up Not only the front panel, both side and top panels are made of aluminum panels and attached to a robust steel shassis. These heavy parts eliminate vibrations, and allow all internal circuits to always perform under stable conditions. An A4-size body allows users to place the unit small spaces. The Reference 501 series defines a new standard that fits all modern interior with great space-saving design and a timeless presence. No Cooling-Fan, for Quiet Operation Effort to eliminate the signal to noise ratio and ensure high-quality audio playback mean nothing with a noisy cooling fan. To reach both goals of attaining high performance and compact dimentions, Teac carefully arranged the inner-workings to eliminate the need of a fan. There are two parameters that conflict with efficient heat dissipation, the circuit design and chassis design. After careful strategy, effective placement of potential heat-generating components allows this high-performance compact amplifier to operate without a cooling fan. Well-Designed User Interface A firm-torqued volume with a machined aluminum knob, and toggle type main power switch give the user assured operation. The remote control with aluminum facia gives the unit an elegant appearance and very precisive volume control, paces of approximately 1.5dB. To help contribute to the musical atmosphere is the classiest characteistic of the Ai-501Da, the dimmable backlight, and dual analog meters.

Audio, Speaker, and Headphone Amplifiers Hong Kong

To truly appreciate and understand a great pair of hi-fi speakers or headphones require the user to have more than just the speakers or headphones themselves. Aside from having a keen sense of sound, the listener would also need to have the proper equipment to power the speakers or headphones. This is because these higher end high fidelity speakers and headphones typically have a higher power requirement compared to lower end headphones or headphones that are mainly targeted towards the average consumer.

A Power Boost to your Audio

Audio amplifiers function as their name suggests: they amplify power. These devices channel more power through to your headphones or speakers, filling up the gaps in power where your source – where the sound comes from, usually your computer or TV – is unable to deliver enough power to your equipment. When there is not enough power to power a pair of headphones or speakers, the sound comes out soft and difficult to hear; it can also affect the sound of your equipment as it is unable to bring out the full potential of your headphones or speakers.

There are several easy ways to roughly tell if your speaker or headphones require an amplifier. On the packaging of headphones, you will see a term ‘Impedance’ on the specification list. A common headphone will have a very low impedance ranging from 8 to 16 ohms, which can be powered by your computer and smartphones easily, but typically anything more than that could do with a little help from an amplifier.

Speaker Amplifiers Hong Kong

Most common everyday speakers, especially those meant for computers, are called ‘active speakers’; this means that the speakers come with a built-in amplifier. For those that require an external amplifier are called passive speakers, and are usually much better in sound. Speaker amplifiers such as those from Yamaha or Denon usually take up a little bit more space because it is usually made to power very large passive speakers at home. Pairing the right speakers with the right amplifiers can properly unlock the full potential of your speakers for maximum enjoyment.

Headphone Amplifiers Hong Kong

Headphone amplifiers generally have two different uses: those set at home for listening on much higher-end headphones, and the portable ones for the headphone listeners on the road. Home headphone amplifiers from makers such as Sony are similar to the speaker amplifiers, being large and requiring a direct-current power.

Portable Amplifiers Hong Kong

Portable ones come in various sizes, from being as small as an iPod Nano to a larger size as that of a smartphone – Fiio, in particular, is a brand that makes a number of these. Portable amplifiers are powered by a battery and is commonly attached to digital music players or smartphones to provide an additional boost in power for listening to music on the go.
