Integrated Amplifier TEAC AI-503

- The AI-503 is an integrated amp and USB DAC that supports inputs up to 11.2MHz DSD and 384kHz/32-bit PCM. The DAC/preamp, which is the heart of the unit, follows the same design concept of our UD-503 and adopts a dual-mono circuit design that is fully balanced. Separate VERITA AK4490 D/A converters - made by Asahi Kasei Microdevices Corporation - are used for the left and right channels. In addition to a USB digital input (for Windows/Mac computers), optical/coaxial digital input and RCA analog input, we have also enabled high-resolution wireless audio listening by including a LDAC-compatible Bluetooth receiver. Furthermore, with a combined 3.5mm optical digital/stereo mini jack on the front panel, the unit supports wired, as well as wireless, input from DAPs.

Features

- DAC with a dual-mono configuration that supports resolutions up to 11.2MHz DSD and 384kHz/32bit PCM.

- Separate VERITA AK4490 D/A converters made by Asahi Kasei Microdevices Corporation used on left and right channels.

- Bluetooth receiver that supports LDAC/Qualcomm aptXTM (as well as AAC and SBC).

- Filter type can be switched, choosing from 2 DSD digital filters, as well as 4 PCM filters and off mode.

- Two built-in high-precision dedicated clocks for 44.1kHz and 48kHz signals and their multiples (enabled during USB asynchronous transmission).

- TEAC-QVCS high-precision volume control circuit with fully-balanced structure.

- High-output Class-D power amplifier (made by ICEpower a/s).

- Headphone amp with discrete, push-pull circuit and a maximum output of 280mW+280mW (TEAC-HCLD circuit).

- Ground connection supported by 3.5mm 4-pole stereo headphone jack (combined with regular 3.5mm stereo mini type).

- High-capacity toroidal-core power transformers.

- Pair of RCA analog input jacks.

- Volume-controlled pair of RCA analog output (pre-out) jacks.

- USB/coaxial/optical digital inputs (one each on back panel).

- Combined round optical digital/3.5mm stereo mini jack (on front panel).

- Dual analog level meters with adjustable brightness.

- Low-energy consumption design and automatic power-saving function.

- All-metal enclosure provides both vibration resistance and a stylish appearance in an A4-page-sized footprint that can fit on a desk.

- Dedicated remote control included.

- IEC inlet.

- Compliant with RoHS.
