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.
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 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.
