Product Description
The Marantz Model 50 Integrated Amplifier is the best value integrated amplifier in the range. It has an output of 70 watts per channel and features the Marantz current-feedback power system. Additionally, the HDAM-SA3 circuit design will drive your speakers with total control.
The amplifier is a class A/B unit for optimal efficiency. Moreover, there are many analogue inputs including a MM phono input. The case has a modern look with symmetry and a tooled aluminium front panel.
Class A/B power amplifier
The power amplifier in the Marantz Model 50 Integrated Amplifier is a class A/B unit and will reveal details in the music you may have missed before. Class A/B is a combination of Class A and Class B. Class A normally has a single output device and hence has no crossover distortion.
However, it is extremely inefficient and needs a huge power supply to provide enough output. On the other hand, Class B is much more efficient but can suffer from crossover distortion. This tends to be more noticeable at low volume levels.
As a result, Class A/B was developed. This uses Class A at low volume levels but gradually changes to Class B for higher outputs
Analogue simplicity
Analogue reigns supreme in the Marantz Model 50 Integrated Amplifier. There is no digital circuitry that can interfere with the analogue purity of the design. Having digital circuits in an integrated amplifier may be convenient but it can also degrade the sound unless the circuity is isolated from the analogue circuits. As a result, the Marantz Model 50 Integrated Amplifier has no internal digital systems.
Beautiful case design
The Marantz Model 50 Integrated Amplifier has a modern design but is timeless in its symmetry and simplicity. The volume and source select knobs balance the design while the traditional bass and treble controls sit in the middle. Moreover,
The porthole display lets you see the volume setting at a distance. The machined aluminium from the panel offers a touch of class and luxury. There is also an ultra-precise volume control that always maintains channel balance.
Excellent connectivity
Beginning with the MM phono input, there is a mass of connectivity with the Marantz Model 50 Integrated Amplifier. The RCA phono input sockets are ultra-premium and further apart than usual to accommodate large plugs. Six line-level analogue inputs are available and there is a tape loop.
Other features include an always-on preamp output for connection to an external amplifier. There is also a subwoofer output and a power amp input that bypasses the tone controls.
This can be used to connect a variable output source. Lastly, there are two sets of speaker terminals so that you can use a second pair of speakers in another room.
Phono input
The phono input is suitable for moving magnet cartridges with an output of around 5mV. Moving coil cartridges have a much lower output at less than 1mV. As a result, you may need an external preamp for MC cartridges. However, there are plenty of spare inputs to connect a preamp.
