Audio Database


This pre-main amplifier inherits the design philosophy and advanced circuit technology of the PM14SA and PM-17SA, and is designed for next-generation audio.

The pre-power independent configuration brings out the regenerative capability of the current feedback type preamplifier.

The preamplifier section uses a current feedback type preamplifier with high drive capability and low noise / high slew rate, ensuring high speed and dynamic range for next-generation audio.
In addition, the pre-out terminal is mounted, and bi-amplifier drive is also possible in cooperation with SM6100SA.

A current feedback type is also used in the power amplifier section to increase the speed.
Power devices use L, A, P, and T with superior high-frequency characteristics.

A speaker terminal made by WBT is adopted for the speaker terminal, and banana plug and Y lug are also supported.

The Rec out output from the CD has a dedicated Rec buffer amplifier.

Equipped with a CD direct input that is directly connected from the input to the preamplifier section via a dedicated relay.

Equipped with tone control and loudness.

An inlet type AC cable is used.

It comes with a system remote control and can also operate Marantz DVD players, MD recorders and CD recorders.
