ATC Electronics

Studio-derived control, engineered for musical truth

ATC Electronics Range Introduction

ATC designs electronics with the same philosophy as its loudspeakers:
neutrality, stability and control come before features or flavour.

ATC electronics are engineered to:

• preserve timing and dynamics

• remain stable under real-world loads

• operate reliably over decades

At Authentic High End, we present ATC electronics as reference tools, equally suited to studio-inspired and uncompromising domestic systems.

What Defines ATC Electronics

Current & Stability First

ATC designs its electronics around:

• real current capability

• conservative, linear operation

• predictable behaviour with demanding loudspeakers

There is no intentional voicing or sonic seasoning.

Fully Analogue Where It Matters

ATC electronics feature:

• fully analogue signal paths

• no DSP or digital manipulation

• minimal circuitry for maximum signal integrity

Digital functionality is added only when it does not compromise performance.

Professional Reliability

ATC’s studio heritage translates into:

• robust power supplies

• excellent thermal stability

• long-term serviceability

These are components designed to be used daily, not replaced quickly.

ATC Integrated Amplifiers

ATC SIA2-100

The SIA2-100 is ATC’s most compact integrated amplifier.

• Fully analogue integrated design

• High-current output stage

• Designed to drive ATC passive loudspeakers

• No DAC, no phono stage

It delivers ATC’s amplification philosophy in a clean, space-efficient one-box solution.

ATC SIA2-150

The SIA2-150 builds on the SIA2-100 platform with increased power and current reserves.

• Fully analogue signal path

• Greater dynamic headroom

• Enhanced loudspeaker control

It is the preferred choice when simplicity must meet higher system demands.

ATC Preamplifiers

ATC SCA2

The SCA2 is ATC’s reference line-level preamplifier.

• Fully analogue design

• Precision volume control

• Extremely low noise floor

Its role is singular: manage sources and gain without sonic influence.

ATC CA2

The CA2 is ATC’s reference preamplifier with balanced topology, designed for maximum signal integrity.

• Fully analogue preamplifier

• Balanced and single-ended connectivity

• Designed to partner ATC power amplifiers

The CA2 sits at the heart of ATC’s highest-performance passive systems.

ATC CDA2 Mk2

The CDA2 Mk2 is ATC’s reference CD player with integrated DAC and analogue output stage, and can function as a digital source and control component.

• High-quality disc transport

• Integrated digital-to-analogue conversion

• Can directly drive ATC power amplifiers

In many systems, the CDA2 Mk2 replaces a traditional preamplifier.

ATC Power Amplifiers

ATC P2

The P2 is ATC’s high-power stereo power amplifier.

• High continuous current delivery

• Designed for larger rooms and demanding loudspeakers

• Maintains ATC’s neutrality and control

ATC P1

The P1 is ATC’s mono power amplifier, intended for maximum performance.

• True mono architecture

• Maximum channel separation

• Exceptional dynamic headroom

Used as a pair, P1 amplifiers form ATC’s no-compromise amplification solution.

Listening Character Across ATC Electronics

Across all ATC electronics, listeners can expect:

• absolute bass control

• stable, unforced dynamics

• zero tonal emphasis

• long-term listening comfort

ATC electronics do not add excitement — they remove uncertainty.
