SE PA-100 | Stereo Power Amplifier

Powered by HGBT technology (High Gain Bandwidth Technology) and high-performance bipolar transistors, the SE PA-100 is a precision analog stereo amplifier engineered for very low output impedance, very high damping factor, and exceptional control across the audible range. With 2 × 120 W RMS into 8 Ω, it is designed for use with the SE NF-3 and SE MF-4, SE MF-4S, and can also drive the SE MF-2.1 in many applications.

The SE PA-100 is a precision stereo amplifier built on Strauss HGBT (High Gain Bandwidth Technology) architecture. Its output stage uses bipolar high-performance transistors to achieve very low output impedance (0.003–0.006 Ω), resulting in damping factors exceeding 2800 at low and mid frequencies. The regulated power supply supports international AC mains voltage, while the 10 mm aluminum housing acts as a fully grounded thermal block with pure convection cooling. The design prioritizes low noise, minimal distortion, and maximum current delivery for demanding loudspeaker loads.
