7The concept : Instantaneous

current delivery capability

Even if amplifier have the same power specifications, their performance may not be the same due to a difference in current delivery capability.

The delivery capability of power amplifier depends on how instantaneous the current supply is.

That’s why the power supply for the MA-9S2 was completely revamped to give it a truly instantaneous current supply capability that has been increased three times as much compared to any Marantz product designed before.

7Fully balanced monaural power

amp

To minimize the influence of strong “kick back current” occurring from the loudspeaker system, the circuit for the power amp consists of two amplifiers giving a voltage gain amp of 23dB, in a push-pull balanced construction, for the final buffer amp of 6dB.

7HDAM SA

The feedback impedance of the Current Feedback circuit was reduced to its minimum to make it faster.

We developed a new Hyper Dynamic Amplifier Modules (HDAM), a separated module operating as a buffer for the amplifier.

7Choke input system

The power supply of the voltage gain amplifier’s adopted choke input system has few ripples and is durable with load changes. This can prevent noise from the amplifier as well as reduce noise from the primary winding, resulting in a clean power supply.

7Ultra low impedance amplifier

The buffer amplifier’s power supply block, which supports the high current delivery capability, uses a capacitance input system to realize very low impedance.

The new developed toroidal power transformer, the low impedance electrolytic capacitors, the very large gauge internal wiring, and the thick pattern PWB all contribute in supplying the required power.
