Designed and manufactured in France, the Atoll Electronique AM100 Signature is a high-performance stereo power amplifier engineered around dual-mono topology and Class A/B discrete circuit design. It delivers clean dynamic headroom, exceptional instrument separation, and the characteristic warmth associated with MOS-FET output stages.

Key Architecture & Highlights

  • Dual-Mono Power Supply: Incorporating two independent 340 VA toroidal transformers ensures complete channel separation, preventing power sag under high dynamic demands and maintaining a dark background with precise soundstaging.

  • MOS-FET Output Stages: Polarized in Class A/B, MOS-FETs yield a tube-like warmth in the midrange while preserving high-speed transients, tight bass grip, and extended high-frequency response.
  • Flexible Operating Modes: Equipped with an internal switch to bridge the unit into a mono power block. It can be deployed as a single stereo unit, in a dual-mono setup (two AM100 units), or for bi-amplifying bi-wireable speakers.
  • Connectivity & Control: Includes standard RCA stereo inputs, pass-through RCA stereo line outputs ( simplifying bi-amping configurations), gold-plated binding posts, and a standard 12V trigger input for auto-powering alongside an Atoll preamplifier (e.g., PR200 Signature or PR300 Signature).
  • Build Quality: Features a heavy-gauge steel chassis equipped with a 4 mm brushed aluminum front panel, available in black or silver.
