Informations
Product description
Handcrafted in Brecey, France, the Atoll IN50 Signature is an entry-level audiophile integrated amplifier built on an analog-first philosophy. Rather than cluttering the base model with digital extras, Atoll prioritizes top-tier discrete components, muscular power delivery, and effortless modular upgrades.
Core Highlights
-
MOS-FET Output Stage: Employs a single push-pull MOS-FET configuration per channel for a dynamic presentation that combines tube-like warmth with sharp transient speed.
-
Pure Analog Circuitry: Features double-sided nickel/gold-plated PCBs and high-grade MKP coupling capacitors across a fully discrete signal path.
-
Flexible Connectivity: Outfitted with dual pre-outs (perfect for subwoofers or bi-amping) and a dedicated BY-PASS input to run the amp as a standalone power amplifier in home theater setups.
-
Premium Build Quality: Houses an ALPS motorized volume potentiometer behind a sleek, 4 mm brushed aluminum faceplate.
-
Modular Expansion Options: Keeps the base model purely analog while offering dedicated internal slots for optional add-ons:
-
Phono Cards: P50 (MM) or P100 (MM/MC) internal phono stages.
-
Digital DAC Cards: DA100 (Optical/Coaxial) or DA200 (Optical/Coaxial plus USB-B with PCM/DSD support and Bluetooth).
