The Mosconi Atomo 2 is a compact 2-channel Class D amplifier rated at 220W RMS (2 x 100W RMS at 4 ohm, or 1 x 220W bridged), part of Mosconi's Atomo range. Measuring just 86 x 65 x 34mm, it suits small hi-fi builds or boosting a factory head unit.
Key specifications
- Channels: 2, Class D
- Power at 4 ohm: 2 x 100W RMS or 1 x 220W bridged
- Power at 2 ohm: 2 x 110W RMS
- Filter: off / high pass / low pass, 80Hz, 12dB/oct
- Input range: 0.4 to 5 Vrms (low level), 1.6 to 20 Vrms (high level)
- Start&Stop compliance: yes
- External fuse: 1 x 15A
- Dimensions: 86 x 65 x 34mm
- Weight: 275g
Mosconi Atomo 2
The Atomo line builds on the digital technology developed in the Mosconi Pico range to deliver efficient, high-quality amplification in a mini format.
The compact dimensions make it well suited to small hi-fi systems or as a straightforward upgrade for factory radios where space is limited.
Features
- Extremely compact 2-channel Class D amplifier
- Wide input voltage range: 0.4–5 Vrms (low level) / 1.6–20 Vrms (high level)
- Inputs flexibly configurable (floating/fixed ground, switchable load resistors)
- Remote detection (BTL)
- High pass / low pass filter
- Inputs designed to Molex industry standard (Micro-Fit)
