Product description

Capable of 5.6 MHz DSD Native Playback

• • USB input port allows DSD native playback, which converts 5.6 MHz DSD files directly into analog signals without the requirement of first converting it to PCM
  • Supports both the ASIO2.1 and DoP (DSD over PCM) conversion methods
  • Using the AI-301DA in conjunction with the Teac HR Audio Player high-resolution playback software (available for free download on the Teac website), you can explore the world of high-resolution digital audio, including 5.6 MHz DSD or 32-bit/192 kHz PCM files, without struggling to have to understand complex settings

Asynchronous-Mode-Capable USB Input

• • When receiving digital audio signals from a computer via USB cable, the unit can operate in asynchronous mode, controlling the timing of the input signal using the UD-301's internal clock
  • With asynchronous transmission over USB, signal compromising jitter is effectively eliminated, allowing digital audio signals to be transmitted in a pure, unadulterated state

Coaxial and Optical Digital Inputs Offer Versatility

• • Besides its USB audio input, the AI-301DA comes with S/PDIF inputs for versatile compatibility
  • The coaxial digital input supports up to 24-bit/192 kHz while the optical digital input supports up to 24-bit/96 kHz digital audio

Wireless Playback at High Sound Quality via Bluetooth Using the aptX Codec

• • Supports the aptX codec, which offers wireless playback capability via Bluetooth hardware
  • The codec also offers low latency and an error recovery function, both crucial features for achieving high-quality audio performance
  • Memory capacity for up to a maximum of eight Bluetooth device pairings

Burr-Brown PCM1795 DAC

• • Burr-Brown PCM 1795 D/A converts 5.6 MHz DSD or 32-bit/192 kHz PCM digital data into analog form
  • The analog signal, which is derived from huge digital audio data files, delivers a finely etched sound

ICEpower Class-D Amplifier Circuit

• • Based on the class-D amplifier manufactured by ICEpower
  • Converts a high-resolution sound source into high-definition speaker signals using a feedback loop between a hybrid feedback controlled oscillating modulator (HCOM), which faithfully amplifies the signal, and a multivariable enhanced cascade control (MECC)
  • 60W + 60W (4Ω) amplifier creates very little heat, eliminating any need for a cooling fan, thus affording a quiet environment that's optimal for music appreciation

CCLC Circuits with Headphone Amplifier

• • 100mW + 100mW output (at 32Ω load) headphone amplifier uses CCLC (Coupling Capacitor Less Circuit) technology
  • Eliminates the negative impact of capacitors on sound quality, providing full low-frequency sound and a responsive headphone listening environment

Well-Engineered Aluminum Enclosure, Compact Proportions

• • Features 8.5" wide casework which allows greater freedom in positioning the amplifier
  • External highlights include aluminum panels and a motor-driven volume knob with smooth tactile feel
  • The solid enclosure, underpinned by the metal chassis, is impressively inert, minimizing the effects of vibration on the unit's sound quality

Simple Operation with Auto Power On

• • Auto Power On function automatically switches on the unit's power when it senses a digital signal input
  • When the amplifier is connected to optical digital audio output from a television set, just switching on the television turns on the power of the AI-301DA, enabling instant output of high-quality sound without having to adjust any other settings

Combine with the Separately Available LS-301 Speakers to Create a Simple High-Resolution System

• • The AI301-DA Amplifier can be combined with LS-301 coaxial speaker (available separately), which is specifically developed to match it to create a high-resolution sound system
  • AI301-DA also features a subwoofer pre-out plug so that the equally compact 2.1-channel LS-WH01 satellite/subwoofer system (available separately) can be used along with the amplifier

Other Features

• • Screw-type speaker terminals (banana plugs, 8 AWG gauge cable compatible)
  • Three-pin IEC AC socket for power
  • Customized remote control included
  • Auto Power Save function
