Mosconi ATOMO 1 by Gladen
The Mosconi ATOMO 1 is a 1-Channel Amplifier from Gladen in a compact format measuring 86 x 65 x 34 mm and weighing 280 g, with a black anodized surface. Output power is 1 x 205 W RMS at 4 Ohm (250 W @ 16 V) and 1 x 350 W RMS at 2 Ohm, with a minimum load of 2 Ohm using a music signal. Input range is 0.4–5 Vrms (Low-Level) and 1.6–20 Vrms (High-Level). Inputs are flexibly configurable (floating/fixed ground, switchable load resistors) and remote detection in BTL mode. Onboard filter can be set to OFF or Lowpass with 12 dB/Oct and 80 Hz. Power supply is 10–16 V, unregulated push-pull DC-DC converter, fuse rating 1 x 20 A, efficiency > 75 %, thermal shutdown at 93 °C. Start&Stop compatible and available in 12V and 24V versions. Low/High Level inputs via Micro-Fit, speaker output and power connection via Mini-Fit.
