Marantz MODEL 50 Stereo Integrated Amplifier - Black

The Marantz MODEL 50 is a two-channel integrated amplifier built around a Class EEEngine topology, offering a straightforward high-fidelity amplification option for dedicated stereo listening setups. With six analog inputs and a clean signal path, it serves listeners who prioritize source flexibility and low-distortion performance over digital feature sets.

Output is rated at 100 watts per channel into 8 ohms and 70 watts into 4 ohms, with total harmonic distortion measured at 0.02%. Frequency response spans 5 Hz to 100 kHz, dynamic range reaches 112 dB, and the signal-to-noise ratio is 112 dB within the audible range. The unit operates on AC 120V/60Hz and occupies a 3U rack slot at 17.4 x 16.7 x 5.1 inches.
