The Atoll MA100 is a two-channel power amplifier designed with a dual mono architecture using discrete components for excellent stereo separation and dynamic range. It delivers 60 W per channel into 8 ohms and 80 W per channel into 4 ohms, with the ability to bridge into a monoblock delivering up to 150 W at 8 ohms. The amplifier features a custom 170 VA toroidal transformer power supply with 16,600 µF total capacitance, MOS-FET output transistors, and class A/B operation. It has a robust metal chassis with a 4 mm aluminum front panel and gold-plated screw terminals for speaker connections. Inputs include 2 RCA jacks and a 12 V trigger input for remote power control. The MA100 is known for its distinctive sound profile with deep bass, lush midrange, and extended yet smooth highs, making it ideal for pairing with premium bookshelf speakers. It is compact, measuring 320×230×83 mm and weighing 4 kg, suitable for small stereo or multi-room systems. The amplifier is handcrafted in France and available in black or natural aluminum finishes.
