Rogue Audio Atlas Magnum III Power Amplifier

Ultralinear mode provides 100 watts per channel for maximum power and punchy, detailed dynamics. Triode mode reduces the output to 60 watts per channel, offering a smoother, warmer, and more intimate sound signature.

The amplifier features a user-friendly bias adjustment system. You can easily monitor and calibrate the bias using the integrated meter and controls, ensuring your tubes operate at peak performance without needing professional service.

Yes, the Atlas Magnum III includes dedicated output taps for both 4-ohm and 8-ohm speakers. You should connect your speakers to the corresponding terminals on the back to ensure optimal power delivery and impedance matching.

The slow start feature gradually powers up the amplifier to protect the internal components and extend the lifespan of the vacuum tubes. This prevents the electrical stress that can occur during a sudden, full-power startup.

With 100 watts per channel in Ultralinear mode and a massive power supply, this amplifier is capable of driving a wide range of speakers, including those with lower sensitivity. However, always check your speaker's impedance requirements to ensure they are compatible with the 4 or 8-ohm output taps.

The Atlas Magnum III uses a complement of two 12AX7s, two 12AU7s, and four KT120 power tubes. These were selected to balance high-fidelity transparency with the classic harmonic richness expected from a high-end tube amplifier.
