hI-rES auDIO DESIGNED BY PHIL JONES
horn loaded ribbon tweeter
The A80 Horn Loaded ribbon tweeter is the same as the A100's. The thin aluminium ribbon diaphragm has a high sensitivity, superb transient response , extended
frequency range and well-refined resolution.
It meticulously formulated horn shape produces directional and optimized high frequencies from the ribbon tweeter, so they are aimed at the listeners,
minimizing unwanted effect from room reflection.
4.1 inch aluminium cone
33mm vc mid-woofer
The mid-woofer is a 4.5 unit with a hard anodized aluminium alloy cone suspended in a heavy , ultra heavy cast magnesium alloy frame.
The proprietary aluminium 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 30mm diameter voice coil is unusually larger than most loadspeakers of this size. It has been shown that larger voice coils have less power
compression because they run at a cooler operating temperature.
Distortion signal processing
The entire digital system is built on a multi-core signal processor XMOS XU216, a 16-core
powerful audio processor based on XMOS xCore200 architect, which is proud of having up to
2000MIPS processing horse -power
Full digital amplifier
The power amplification part is built with 2 pieces of TAS5754 Class-D amplifier from Texas
instrument. The up-to 192KHz input sample rate support guarantees the entire link of
digital processing run without any change of sample rate of signal. It's 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.
Bluetooth V5.0 with aptx
The Bluetooth audio receiver is built on Qualcomm's Bluetooth V5.0 chipset, which supports APT-X decoder, and offers a far better audio playback quality than what a traditional Bluetooth
SBC codec can present
Transparent internal wiring
The A80 uses TRANSPARENT audiophile grade speaker cable made in the USA for internal wiring. Signals are transferred with utmost accuracy and minimum loss.
With these cables, you are brought a step closer to music.
Back panel control
The volume of the subwoofer can be adjusted by the master volume control. A80's independent treble and bass adjustment function can help the user to easily set the brightness of highs-frequency and the amount of bass according to the size of the room.
The USB digital audio interface on the A80 supports UAC2 audio application which can hold an input sample rate up to 192 KHz. This audio application effectively avoids signal degradation and dynamic range loss due to the PC audio DA.
