Powerful and Precise Class A/B Amplifier
Even difficult to drive loudspeakers will sound effortless with the high-current, dual-device amplifier in MODEL 50. By using two parallel output transistors per channel rather than one, MODEL 50 delivers substantially higher current to loudspeakers than previous models in this class. This technique results in sound that is more effortless, dynamic, and lifelike than models typically found in this price range.
Six Analog Inputs
With a collection of available analog inputs, MODEL 50 can accept audio from myriad source components and includes upgraded connectors for CD and Phono inputs.
MM Phono
A built-in moving magnet phono stage is perfectly tuned to reveal details in your vinyl you never knew existed.
Subwoofer Out
Want more bass? Simply connect a powered subwoofer to the dedicated RCA output.
Stereo Preamp Out
MODEL 50 grows with you. Stereo preamp outputs leverage discrete HDAM design with external amplification.
Five-Year Warranty
Marantz is built with care. A five-year parts and labour warranty protects your investment in the Most Musical Sound.
Current Feedback Amplification
Current feedback amplification is a well-known, Marantz-original circuit technology, thoughtfully designed to match the requirements of hi-res music for wide-bandwidth, high-speed reproduction. Marantz current feedback amplifiers reduce the need for phase compensation by minimizing negative feedback. This simplifies the signal path and results in excellent transient response and superb sonic transparency across the full bandwidth. Unlike conventional voltage feedback topology, current feedback also makes the power amplifier capable of driving difficult loudspeaker loads, meaning MODEL 50n is the ideal amplifier for a very wide range of loudspeakers.
Hyper Dynamic Amplifier Modules (HDAM-SA3)
While many brands claim unique engineering in sensitive and analog circuits, most use commonly available integrated op-amps in critical signal paths. Those op-amps can compromise audio integrity and limit design ingenuity. Marantz developed an entirely unique replacement for integrated circuits using ultra-high-quality discrete components. Marantz HDAM circuitry outperforms traditional op-amps both in the listening room and the laboratory. Very high-speed signal handling dramatically improves bandwidth. Clever amplification design minimizes distortion and ideal layout silences noise. Ultimately, the flexibility a fully discrete solution provides us the freedom to engineer the ideal basis for extraordinary performance. MODEL 50n utilizes the upgraded HDAM SA-3.
Marantz Musical Phono EQ
Since our first product, the Audio Consolette, we’ve maintained our commitment to vinyl with the Marantz Musical Phono EQ stage. This version of Marantz Musical Phono EQ uses two-stage amplification, allowing less gain per stage for lower distortion. MODEL 50 combines Marantz HDAM technology with JFETs in the input stage, providing high input impedance that eliminates the need for AC coupling capacitors and vastly simplifies the signal path, dramatically improving the signal purity overall.
High-Precision E-Vol Electronic Volume Control
MODEL 50 uses an ultra-precise electronic volume control system that adjusts both the circuit gain and the output voltage. This system maintains high dynamic range and limits noise across a far broader volume range than traditional systems. More traditional integrated amplifiers use basic potentiometers which can suffer from poor channel balance and increasing noise and distortion over time.
