AiOS is a new kind of music system for a new generation. What does that mean? Simply put, music lovers and audiophiles alike have many more choices today when it comes to how they listen to music. As a music system with 150 watts of Class AB power, AiOS combines sources and inputs designed around this new age. AiOS is also fully MQA Certified, but unlike other MQA products to date, AiOS will playback any MQA sample rate up to 16x. This means despite the original sample rate of the MQA file, the MQA decoder will extrapolate the file to either a 705.6 or 768 kHz sampling rate for stunning realism and studio quality sound. For non-MQA files, AiOS can stream or playback native PCM files up to 32 bit 384 kHz (.WAV files up to 768 kHz), plus DSD 64, 128, 256, and 512. Connect AiOS to your home network (Wi-Fi or Ethernet) and stream all of your digital music stored on your networked computer(s) or NAS drive(s) with simple plug N play UPnP, DLNA, and SMB connectivity. Also, available through your home network connection are integrated internet music streaming services, Spotify, TIDAL, vTuner, and others being added. For those that may find a home network connection too intimidating, AiOS allows you to insert a SD Card into the front SD Slot. You can also use a USB flash drive or USB hard drive loaded with digital music files directly to AiOS’ three USB-A inputs, all without a computer or network connection for direct playback! How about Bluetooth? Today, Bluetooth is ubiquitous and AiOS can certainly connect to your smartphone or tablet using the latest Qualcomm aptX© Bluetooth technology. However, AiOS has an extra trick up its sleeve. AiOS can SEND any of its selected sources to Bluetooth enabled headphones or speakers for a completely wireless music system. Place AiOS anywhere to add beauty and elegance to any room or décor and don’t fuss over unsightly wires when paired to a set of Bluetooth enabled speakers.
Speaking of beauty and elegance, AiOS is visually transformative. With the touch of a button, AiOS can change its backlit keys/buttons and center LCD display (together or individually) to six different preset colors including one custom color preset, or adjust any color as you see fit within the entire color spectrum. As if the all-aluminum gunmetal gray chassis and side panels (standard) weren’t handsome enough, AiOS offers five additional side panel color options to ensure AiOS can create the perfect blend of sight and sound to match both your lifestyle and décor choices within any setting.
Finally, AiOS includes multiple analog and digital inputs and outputs, including subwoofer output, preamplifier output, and more! Whether using AiOS as a secondary music system, or as the centerpiece of your home entertainment system, AiOS is right at home within a metropolitan condominium setting, office, bedroom, game room, dormitory, or any room or setting for the design conscience music lover.

MQA (Master Quality Authenticated)
MQA is a technology that captures the full magic of an original studio performance. Using pioneering scientific research into how people hear, MQA delivers master quality audio in a file that’s small enough to stream or download – the days of sacrificing quality for convenience are over.

Master Quality Authenticated (MQA)
The AiOS includes MQA technology, which enables you to play back MQA audio files and streams, delivering the sound of the original master recording. This ensures that MQA-encoded audio files and streams sound exactly like the source. ‘MQA’ (Green Dot) indicates that the unit is decoding and playing an MQA stream, and ‘MQA Studio’ (Blue dot) denotes provenance to ensure that the file and sound is approved by the artist, producer, and or original engineer.
