Play audio from nearly any source with the Airpulse A300 Bluetooth Speaker System. This system has optical, digital coaxial, balanced stereo XLR, USB Type-B, and stereo RCA inputs, plus Bluetooth connectivity with aptX for wireless connectivity with your compatible devices. The speakers consist of a 6.5″ mid-woofer and an aluminum ribbon tweeter to provide full-range audio at up to 80W per channel to fill your space with sound.
All connectivity is via the powered right speaker, which connects to the passive left speaker with the included speaker cable. A remote control, optical cable, stereo RCA cable, and stereo RCA to 1/8″ adapter are all included for instant connectivity.
The A300 cabinet is built with 25mm thick rigid MDF with cherry wood veneer finished in a satin lacquer. Internal bracing supports and stabilizes the drivers and helps minimize cabinet resonance. To further reduce sound coloration, the cabinet interior is fully lined with 36mm thick waved sound absorption material. The oval shaped vent tube in the A300 is carefully designed to minimize wind noise. The internal wiring is made by TRANSPARENT for enhanced accuracy and minimal signal loss.
The horn-loaded ribbon tweeter of the A300 inherits the mechanism of the tweeter in the Airpulse 7001 near-field monitor speaker. The ribbon diaphragm is designed for high sensitivity, superb transient response, extended frequency range, and well-defined resolution.
The mid-woofer is a 6.5″ driver with an anodized aluminum alloy cone suspended in a heavy-duty, rigid cast magnesium alloy frame. The Proprietary Aluminum Alloy Cone (PAAC) of the mid-woofer was designed from analysis of all types of cone geometry and materials using a Klippel Laser Doppler Interferometer. It features a large underhung motor structure with a high-gauss neodymium magnet and a 50mm diameter edge-wound, copper-clad aluminum ribbon voice coil to gain maximum linear excursion and control that also reduces the weight of the driver, allowing the speaker to have a fast transient response as well as total loss-modulation distortion.
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. The cooler running temperature of the voice coil also has the added benefit of a more reliable loudspeaker, since a cooler voice coil means less chance of speaker failure.
For uncompromised performance, the A300 mid-woofer uses a rigid cast-magnesium alloy frame. Its rigidity 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 leads to increased dynamics and power handling, and ultimately, a satisfying musical experience.
The entire digital system is built on a multi-core signal processor the XMOS XU216, a 16-core powerful audio processor based on XMOS xCore200 architecture, which boasts to have up to 2000 MIPS processing horse power. With its unique parallel structure, it is well equipped 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 amplifier section of the A300 is composed of three TAS5754 Class D amplifiers from Texas Instruments. This component combines a high input sample rate support and a high output PWM carrier frequency to help achieve low background noise and distortion. The up-to 192 kHz input sample rate support guarantees the entire link of digital processing run without any change of sample rate of the signal. Its 768 kHz output PWM carrier frequency twice the 384 kHz of other Class-D amplifiers is even more suitable to drive the high-sensitivity ribbon tweeter. Each channel’s mid-woofer is driven by one TAS5754 connected in parallel bridge mode. The third TAS5754 is connected in bridge mode for the left and right channel ribbon tweeters.
The analog front end uses Texas Instruments components. With their configuration, the chipsets work at 96 kHz, offering a frequency response up to 40 kHz. The wide-range input frequency response helps guarantee thorough signal acquisition at very low distortion. To avoid cross-talk between the two analog ports, the A300 uses a relay instead of a semiconductor switch.
The SPDIF receiver is the Texas Instruments PCM9211, which supports up to 216 kHz input sample rates. With a very low output jitter, the unpacked audio signal can be delivered to the XMOS processor with virtually zero loss.
The USB audio interface supports the UAC2 audio application and an input sample rate of up to 192 kHz. This audio application effectively avoids signal degradation and dynamic range loss due to the computer’s onboard DAC and provides a new method for high-definition audio playback. The Bluetooth audio receiver is built on Qualcomm’s Bluetooth 5.0 chipset, which supports aptX decoding and offers enhanced audio playback quality over SBC Bluetooth.
The A300 comes with a wireless remote control used for taking control of your sound. You can switch between inputs easily from the comfort of your seat. UPC: 812417031047
