TEAC AI-501DA Integrated Amp

Impressive Power in a Small Footprint

The powerhouse of TEAC's 501 series, the AI-501DA integrated amplifier features 192kHz USB digital audio inputs, low power consumption, a BurrBrown PCM5102 D/A Converter, USB connectivity, Class-D ABLETEC Norway amplifier and a toroidal-core power transformer for a virtually unmatched small-system solution. 

After months of technical research for an amp with high-quality sound and high output power, but low power consumption, the ALC0180 Digital Power Amplifier module, manufactured by ABLETEC, Norway, was decided on to compliment the AI-501DA. Delivering a maximum of 90W per channel of output power at a maximum 55W of power consumption, users are able to enjoy powerful sound without hesitation. This next-generation integrated amplifier consumes only 10W in idling mode, and 0.2W at power-saving standby mode.

Features:
  • 90W/ch at 4 ohms
  • Supports up to 24bit/192kHz USB & Coaxial S/PDIF
  • Supports up to 24bit/96kHz Optical S/PDIF
  • Internal 32bit processing BurrBrown PCM5102 DAC
  • Toroidal-core Power Transformer
  • Schottky Barrier diodes for power supply circuits
  • Dual analog level meters with dimmable backlight
  • Headphone amplifier that employs two operational amplifiers

Fully Digital Path via USB Cable
Just connecting a USB cable between any Mac/Windows-PC and the AI-501DA, a variety of audio formats can be transferred in a fully digital manner. Once the driver software is installed, your playlist iTunes or Windows Media Player turns into part of your high-quality audio system. This allows 24bit/192kHz data transfer mode reduces jitter noise while the digital data travels along the USB cable.

BurrBrown PCM5102 D/A Converter
The AI-501DA employs the highly celebrated BurrBrown PCM5102, allowing 32bit processing across the USB audio input, Optical and Coaxial digital inputs. Parts were carefully selected for the analog circuits. The unit utilizes high-quality operational-amplifiers and electrolytic capacitors already proven on previous high-end models.

Large Capacity Toroidal-Core Power Transformer
An over-sized Toroidal-core power transformer helps deliver high-quality sound without sacrificing energy-efficiency and the unit's compact dimensions. Conventional diodes produce rectification noise that negatively affects the sound of other units. To combat this, TEAC installed Schottky Barrier Diodes to supply a cleaner internal current and reduce rectification noise.

High-Quality Headphone Output
The AI-501DA is also designed for headphone listening, as well as speaker listening. An exclusive operational amplifier is employed on each channel. Conventional hi-fi systems only use a single operational amplifier for both channels.

No Cooling-Fan for Quiet Operation
Effort to eliminate the signal to noise ratio and ensure high-quality audio playback mean nothing with a noisy cooling fan. To reach both goals of attaining high performance and compact dimensions, TEAC carefully arranged the inner-workings to eliminate the need of a fan. There are two parameters that conflict with efficient heat dissipation, the circuit design and chassis design. After careful strategy, effective placement of potential heat-generating components allows this high-performance compact amplifier to operate without a cooling fan.

Full-Metal Construction and Small Footprint
Not only the front panel, both side and top panels are made of aluminum and attached to a robust steel chassis. These heavy parts eliminate vibrations, and allow all internal circuits to always perform under stable conditions. An A4-size body allows users to place the unit in small spaces. The AI-501DA defines a new standard that fits all modern interior with great space-saving design and a timeless presence.

Numerous Inputs and Outputs
The AI-501DA provides sufficient number of audio inputs allowing users to integrate full-scale hi-fi systems with both exsting and future expansions. The device is equipped with two optical inputs and one coaxial input, along with two analog (two stereo) audio inputs. A set of large biding-post speaker terminals accommodates high-grade speaker cables up to AWG8 grade. A detachable AC cable with a 3-polar socket allows user to upgrade to a high-grade AC cable.

Well-Designed User Interface
A firm-torqued volume with a machined aluminum knob, and toggle type main power switch give the user assured operation. The remote control with aluminum face gives the unit an elegant appearance and very precise volume control, paces of approximately 1.5dB. To help contribute to the musical atmosphere is the classiest characteristic of the AI-501DA, the dimmable backlight, and dual analog meters.
