Product Description

ATC SIA2-100 Integrated Amplifier is compact at 2/3 width yet delivers high output power and excellent resolution with an integrated DAC suited to driving small to medium speakers and styling that assures seamless integration with other equipment.

ATC Legacy

SIA2-100 is the newest addition to ATC’s formidable range of top-performance audio electronics and speaker systems made for studio and hi-fi purposes.

One-box Design

SIA2-100 is built to partner the CD2 as a compact separates system and passive stereo loudspeakers. The versatile one-box design for DAC and pre/power amplification has the capability to generate 2 x 100W.

Noise Reduction

SIA2-100 works hard to prevent noise and distortion. The power amps use ATC’s circuit topology that has been refined over the past three decades. Lateral Mosfets in a mutual source structure provide lowest distortion with a broad frequency response. A peak limiter shields the drivers in case of an overdrive. Intermodulation and cross-talk defects are reduced due to discrete power supplies for the pre and power amp sections.

Discrete Design

ATC’s discrete analogue principle and local PS regulators provide maximum functional platform for the SIA2-100’s on-board AKM DAC and USB receiver. The USB input processes PCM sample rates from 44.1 to 384 kHz, while also decoding DSD sources at single rate DSD64 and double rate DSD128. Distortion measures on all inputs are below 0.001%.

Connectivity

SIA2-100 has two pairs of stereo line inputs on RCA phono sockets with a 3.5mm jack socket on the front, a digital SPDIF optical Toslink and coaxial input on an RCA phono socket and USB B input. There is also a pair of stereo power amp outputs on 4mm binding posts and headphone output on a 6.35mm jack socket.

Control

Select input via a push button on the front panel and adjust output volume via a precision Alps potentiometer. Each function on the SIA2-100 is duplicated on the ATC remote control handset supplied. The SIA2-100 chassis is built to be sturdy, rigid and well damped with precision-cut 12mm aluminium front panels finished in brushed and anodised ‘titanium’ silver.

Headphone Amplifier

The SIA2-100 hosts a headphone amplifier and a 3.5mm aux input with greater sensitivity, more suited to connecting with portable audio devices. Both circuits are designed for lowest noise and distortion levels. The headphone amplifier is inclined in class A and can drive a range of 32 to 600 ohms headphones.

Key Features

- Dual line-level analogue inputs
- Three digital inputs: USB, Coaxial, TOSLINK
- Premium AKM 32-bit DAC
- Supports up to 384kHz PCM and native DSD256 (or DSD128 via Mac)
- ATC Discrete MOSFET Output Stage with 100W/Ch
- Headphone amp featuring discrete output stage.
- Handmade in England
