Airpulse A100 Plus Active Speakers

A100 produces 10w×2 RMS for tweeters and 40w×2 RMS for woofers using TI TAS5754 digital amplifiers. The amps operate at ultra-high 768khz PWM frequency for low distortions. Each speaker has a rear-facing bass reflex port for better bass extension. The port is rounded smoothly to achieve low turbulence and high velocity, thus provide better sound performance. The cabinets are made of 18mm MDF with piano glossy finishing, which can minimize unwanted resonances. The interior of A100 is lined with professional-grade sound absorption materials to reduce coloration. Internal wiring is produced by TRANSPARENT to lower signal loss in transmission. The result is full and three dimensional sound with each detail well defined.

A100 comes with an XMOS processor that supports Digital Signal Processing (DSP) for active crossover. Comparing to traditional passive crossover networks, active digital crossovers done in DSP can better distribute sound frequency to tweeters and woofers in a more effective manner but cost more. Benefited by the cooperation with Edifier, the largest Chinese loudspeaker manufacturer, Airpulse managed to offer DSP at an entry-level price range of traditional HiFi. It also comes with Dynamic Range Control that can minimize distortion when volume changes.

XMOS of A100 supports USB asynchronous mode up to 192kHz. Via the asynchronous USB input, the amount of digital data transferred in the frame can be controlled and avoid distortions caused by high levels of jitters.

The A100 is equipped with both digital and analog inputs. TI BurrBrown PCM9211 and PCM1802 digital ADC chips together with the XMOS processor are used for AUX, RCA, USB, Optical inputs. Located on the rear panel of the A100 speakers are three knobs for treble, bass and volume adjustments. There is also a wireless remote for you to control the bookshelf speakers while sitting in chairs comfortably. The latest Bluetooth 5.0 provide premium sound quality. You can easily identify which input your speakers are set to via the LED status indicator on the front. Feel like needing more bass?
