The silver AI-501DA-S Integrated Amplifier with USB Streaming from TEAC features 192 kHz USB digital audio inputs and low power consumption of 55W. The BurrBrown PCM5102 D/A Converter, USB connectivity, Class-D ABLETEC Norway Amplifier, and a toroidal-core power transformer included with this amplifier make it a key component for the 501 series or any other 2-channel audio system.
Integrated Class-D Amplifier by ABLETEC, Norway
With high-quality sound and high output power but low power consumption, the ALC0180 Digital Power Amplifier module, manufactured by ABLETEC, Norway, complements the AI-501DA-S Amplifier. Delivering a maximum of 90 + 90W output power at a maximum 55W power consumption, users are able to enjoy powerful sound. Furthermore, this next generation integrated amplifier consumes only 10W in the idling mode and 0.2W in the power-saving standby mode.
Fully Digital Path via USB Cable allows 192 kHz High-Resolution Audio Playback
Just connecting a USB cable between any Mac / Windows PC and the AI-501DA-S Amplifier, 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 becomes a part of your high-quality audio system. This allows 24-bit / 192 kHz data transfer that reduces jitter noises while the digital data travels along the USB cable.
BurrBrown PCM5102 D/A Converter for a Variety of Digital Sources
The AI-501DA-S Amplifier employs the BurrBrown PCM5102 D/A Converter, allowing 32-bit processing across the USB audio input, and optical and coaxial digital inputs. The parts were carefully selected for analog circuits. The unit utilizes high-quality operational amplifiers and electrolytic capacitors.
Large Capacity Toroidal-Core Power Transformer
An over-sized toroidal-core power transformer helps deliver good 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 has installed Schottky Barrier Diodes to supply a cleaner internal current and reduce rectification noise.
High-Quality Headphone Output Processed by an Exclusive Operational Amplifier on Each Channel
The AI-501DA-S Amplifier is also designed for headphone and speaker listening. An exclusive operational amplifier is employed on each channel.
No Cooling Fan for Quiet Operation
To reach both goals of attaining high performance and compact dimensions, TEAC carefully arranged the inner workings to eliminate the need of a noisy cooling fan, thereby eliminating the signal to noise ratio and ensuring good quality audio playback. There are 2 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.
A Full-Metal Construction and Small Footprint for Any Desktop Set-Up
The front, 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. It defines a new standard that fits all modern interior with a space-saving design.
Large Number Input / Output Allow Users to Integrate a Full-Scale Hi-Fi System
The AI-501DA-S Amplifier provides sufficient number of audio inputs allowing users to integrate full-scale hi-fi systems with both existing and future expansions. The device is equipped with 2 optical inputs and 1 coaxial input, along with 2 analog (2 stereo) audio inputs. A set of large biding post-speaker terminals accommodates high-grade speaker cables up to the AWG8 grade. A detachable AC cable with a 3-polar socket allows the 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 gives the user assured operation. The remote control with aluminum facial gives the unit an elegant appearance and precise volume control, paces of approximately 1.5 dB. Dual analog meters with dimmable backlight contribute to the musical atmosphere.
