Teac AI-303 USB DAC Integrated Amplifier

Teac AI-303 USB DAC Integrated Amplifier

The Teac AI-303 combines a D/A converter, a headphone amplifier and an integrated amplifier in a compact full-metal housing. It handles digital and analogue sources and connects to a television via HDMI.

Connections and sources

• Digital inputs: HDMI (ARC/eARC, HDMI CEC), USB-C, coaxial and optical (Toslink)
• USB-C for PC/laptop as well as smartphones and tablets supporting USB Audio 2.0; automatic device detection. Connecting an iPhone requires an additional Apple USB adapter.
• Two pairs of LINE inputs (RCA) for CD players and analogue turntables with a built-in phono stage
• Subwoofer pre-out
• 4-pole headphone jack with separated ground for left and right channels; 3-pole plugs are compatible

Digital processing

• Supports DSD512 and PCM 384/32, and PCM 192/24 via HDMI
• Full MQA decoding via USB-C, HDMI, coaxial and optical
• Two digital filters plus x2Fs/x4Fs/x8Fs up-conversion; short-delay FIR filter and RDOT filter (Fluency theory)
• NOS mode (Non Over Sampling) with the RDOT filter and up-conversion switched off
• Dedicated SoC for digital processing including MQA decoding and digital filters
• Asynchronous USB mode with internal clock; "Bulk Pet" transfer with four selectable modes

Amplifier and volume

• Ncore power amplifier by Hypex
• Rated output 50 + 50 W (4 Ω) and 25 + 25 W (8 Ω), THD 0.03 %
• Signal-to-noise ratio 100 dB, frequency response 2–70,000 Hz, speaker impedance 4–8 Ω
• Analogue volume control with a resistive ladder-type attenuator on the board
• Headphone amplifier with CCLC design (Coupling Capacitor Less Circuit); crossfeed function via front control; output 220 mW + 220 mW (32 Ω, 1 kHz, THD 1 %, JEITA)

Wireless

• Bluetooth 4.2 with LDAC, LHDC, Qualcomm aptX HD, aptX, AAC and SBC; front LEDs indicate the active codec
• Multipoint connection with two devices at the same time (no simultaneous playback); up to 8 pairings

Housing and build

• Full-metal housing of aluminium/steel panels, with 8 mm aluminium plates on the sides
• Three-point "Stress-less Foot" supports made of milled steel
• Dimensions: 21.5 cm width, 6.1 cm height, 25.7 cm depth; weight 2.3 kg
• Power consumption 63 W

Included accessories

• Power cable
• Remote control RC-1337
• 2 × AAAA batteries
• User manual

Via HDMI with ARC/eARC and HDMI CEC, volume as well as power on/off can be controlled with the television's remote. The television's digital output must be set to "PCM" for this.

Safety information — Audio Everywhere

These notes apply to all HiFi devices and accessories sold by us.

Electronic devices (amplifiers, streamers, CD players, turntables)

Operate only in dry, enclosed indoor spaces. Avoid moisture, direct sunlight and extreme temperatures. Use only the specified mains voltage — do not overload power strips. Do not switch on devices with damaged cables or housings. Keep ventilation slots clear: at least 10 cm distance from walls and other devices. Place stably and securely — no open liquid containers nearby. Keep out of reach of children and pets.

Speakers

Place on a stable surface or suitable stands. No moisture, no direct sunlight. Operate only with matching amplifiers and correctly polarised cables. Do not use as a storage surface. Keep out of reach of children and pets.

Cables (speaker cables, RCA, power cables)

Use only for the intended purpose. Always pull by the plug, never by the cable. Avoid kinks, sharp edges and pressure from heavy objects. Replace visibly damaged cables immediately. Keep out of reach of children and pets.

Accessories (adapters, mounts, cleaning agents, styli, headshells)

Use only according to the manufacturer's instructions. No aggressive cleaning agents, no damp environments. Store small parts safely due to choking hazard. Mount accessories correctly to avoid damage or malfunction.

General notes

Read the operating instructions before use. No unauthorised repairs or opening of devices. Always contact a specialist service for technical problems. We are happy to answer any questions about safe use at any time.
