Designed by Legendary speaker engineer Phil Jones, the all new A100 compact desktop or stand-mount speakers features a custom made 5” aluminum cone woofer. The perfect combination of Hi-Res digital audio processing technology and an aesthetic of understated elegance creates a High-Fidelity audio system with intoxicating sound quality and visual appeal.
The A100 continues to use AirPulse’s unique horn-loaded 3″ aluminum ribbon tweeter and a proprietary 5” aluminum chassis low-distortion bass / mid-range driver. They are housed in an 18-mm thick high-strength MDF cabinet finished with attractive piano black or red lacquer. The cabinet is well-damped and braced to eliminate resonance and vibration. The well-known TRANSPARENT® cable is used in the A100 for internal connections to ensure minimum signal loss. The active speaker has a high efficiency Class D amplifier with digital signal processing (DSP) system, powered by an efficient power supply.
The system in the A100 supports multiple inputs, including Bluetooth, Analog RCA, Digital Coaxial, Optical, USB and RCA Subwoofer outputs. Frequency response ranges from 52 Hz to 40 KHz. It supports Hi-Res high-quality audio playback, and has obtained a Hi-Res official certification.
3″ Horn-Loaded Ribbon Tweeter
5″ Aluminum Cone Low-Distortion Mid-woofer
The Mid-Woofer is a 5” unit with a hard-anodized aluminum alloy cone suspended in a heavy, ultra rigid cast magnesium alloy frame. The Proprietary Aluminum Alloy Cone (PAAC) of mid-woofer was designed from painstaking analysis of all types of cone geometry and materials using a Klippel Laser Doppler Interferometer.
The 35mm diameter voice coil is unusually larger than most loudspeakers of this size. It has been shown that larger voice coils have less power compression because they run at a cooler operating temperature. Sonically this means a more realistic dynamic representation of the music. It is dynamics in music that gives it emotion and exhilaration. The cooler running temperature of the voice coil also has the side benefit of a more reliable loudspeaker since cooler voice coil means much less chance of speaker failure.
Most loudspeakers use round copper wire in the voice coil but we use a far better single layer edge-wound copper clad aluminum ribbon. Ribbon voice-coil wire gives more electrical conductor in the magnet gap and increases efficiency, power handling and lowers distortion.
It features with a under-hung voice-coil with a high power neodymium motor (magnet) to provide a high magnetic flux to cover the whole voice coil of the loudspeaker. This type of magnet structure completely energizes the whole voice coil with allowance for extreme cone excursion giving far better bass and considerably less inter-modulation distortion.
For un-compromised performance, the A100 woofer uses a hyper-rigid cast-magnesium alloy frame. Its rigidity greatly reduces speaker coloration; and its material helps to dissipate heat efficiently from the voice coil much faster than a typical steel speaker frame, which all in combination leads to increased dynamics and power handling and ultimately, a satisfying musical experience rarely gained from a system of this size price range.
The A100 cabinet is built WITH 18-mm thick high-strength MDF finished with attractive piano lacquer. To further reduce coloration, the cabinet interior is fully lined with professional waved sound absorption material.
The oval shaped vent tube in the A100 is carefully designed to minimize wind noise (chuffing).
TRANSPARENT Internal Wiring
The A-100 uses TRANSPARENT® audiophile grade speaker cable made in the USA for internal wiring. Signals are transferred with utmost accuracy and minimum loss. With these cable, you are brought to step closer to music!
The entire digital system is built on a multi-core signal processor XMOS XU216, a 16-core powerful audio processor based on XMOS xCore 200 architect, which is proud of having up to 2000 MIPS processing horse-power. With its unique parallel structure, it is perfectly made for timing-sensitive signal process like audio, especially audio with high sample rate. The dual clock structure at the output stage effectively avoids signal modification between different sample rates, and can further reduce signal distortion.
The power amplification part is built with 2 pieces of TAS5754 Class-D amplifier from Texas Instrument. This component is one of a handful of Class-D amplifiers in the market which combines high input sample rate support and high output PWM carrier frequency. These two charactereristics are essential to achieve low background noise and low distortion. The up-to 192 KHz input sample rate support guarantees the entire link of digital processing runs without any change of sample rate of signal. Its 768 KHz output PWM carrier frequency, twice to 384 KHz of traditional Class-D amplifier, is even more suitable to drive the high sensitivity ribbon tweeter. One TAS5754 is connected in bridge mode for left and right channel woofer and the other amp is connected in bridge mode for left and right channel ribbon tweeters.
The analog front end uses top-of-the-line components from Texas Instrument. With special configuration, the chipset work at 96 KHz to offer a frequency response up to 40 KHz. The wide range input frequency response guarantees thorough signal acquisition with very low distortion. To avoid cross-talk between the two analog ports, A100 uses a relay instead of semiconductor switch.
The SPDIF receiver PCM9211 is also from Texas Instrument, which supports input sample rate up to 216 KHz. With very low output jitter, the unpacked audio signal can be delivered to XMOS processor with zero loss.
The USB audio interface supports UAC2 audio application. A100’s USB interface supports an input sample rate up to 192 KHz. This audio application effectively avoids signal degradation and dynamic range loss due to the PC audio DAC, and provides a new way of high definition audio playback.
The Bluetooth audio receiver is built on Qualcomm’s Bluetooth V4.1 chipset, which supports APT-X decoder, and offers a far better audio playback quality than what a traditional Bluetooth SBC codec can present.
The system reserves a sub woofer signal output in case of situation that needs low frequency rendering with strong bass. Volume of the subwoofer can be adjusted by the master volume control
AirPulse™ A100 Active Wireless Speaker system is a perfect combination of uniquely designed conventional loudspeaker and digital system of XMOS. Meticulous tuning work enables the A100 to accurately reproduce any type of music. Its XMOS integrated USB function makes life much easier, you can play high-quality sound sources without compression and then enjoy lossless hi res music.
A100’s independent treble and bass adjustment function can help the user to easily set the brightness of high-frequency and the amount of bass according to size of the listening environment.
