The Gladen ATOMO 2 is a 2-Channel Amplifier with compact dimensions of 86 x 65 x 34 mm and a black anodized housing surface. The amplifier operates with an input voltage of 10–16 V and utilizes an unregulated push-pull DC-DC converter topology with 1 x 15 A fuse and 75% overall efficiency. The RMS power at 14.4 V includes 100 W x 2 at 4 Ohm, 110 W x 2 at 2 Ohm, and 220 W x 1 bridged at 4 Ohm, with T.H.D. values of 0.3% at 4 Ohm and 0.5% at 2 Ohm and a minimum load of 2 Ohm with music signal. Onboard filters are available as OFF, high-pass, and low-pass with 12 dB/Oct and 80 Hz crossover frequency, the bandwidth is 5 Hz – 40 kHz (-3 dB at 10 W). The low-level input sensitivity is 0.4–5 Vrms, high-level is 1.6–20 Vrms; the inputs are designed as Molex Micro-Fit, speaker and power connections as Mini-Fit. Flexible input configurations include floating/fixed ground and switchable load resistors, the low-level input impedance is 15 kOhm, high-level 21 Ohm (dummy load with jumper), the ground reference (only low level) is open – 21 Ohm. Features include remote detection (BTL), automatic turn-on only high level (BTL source), start & stop compatibility, mute delay of 3 s, and turn-on/turn-off thresholds of 9 V / 6 V. Additional values: quiescent current 0.1 mA, idle current 0.47 A at 14.4 V, thermal shutdown threshold 93 °C (± 5%), and weight 275 g; available in 12 V and 24 V versions.
