Description
 
DC Integrated Amplifier of a Low-TIM design.

The three-step hardwired-connection SEPP output type is used for the equalizer stage handling the delicate signal from a cartridge. Furthermore, it had the outstanding low-noise property and FET of the Marantz requests for price quotations which arranged the pair property thermally and electric nearly perfectly is adopted.
Moreover, the good thing of a property is selected carefully and supplied to the equalizer element.

The good BAX type of a property is used for tone amplifier. It has not only BASS-TREBLE but the MID control.
Furthermore, Low can change a variable span to 2kHz -> 10kHz with a TURN-OVER switchpoint at 500Hz -> 100Hz.
Moreover, it is the interlock with a TAPE-EQ switchpoint, and a tone correction is possible also in the source under sound recording.

In the main-amplifier part, super high fT-Tr borne by the crystal of an LSI process technology and a RF power transistor technology is adopted as dealing with Low-TIM. It is the newest power transistor of a Marantz requests for price quotations which is excellent in a RF property and a switching characteristic, and has an amplification performance of a margin to a super-high region.
And the power transformer is made into each pre & power with the special purpose. Furthermore, the mass type of 15000 micro Fx4 of a Hi-Fi design is especially adopted as a power transformer at the capacitor using a large-scale right-and-left independent-source scheme. This has realized the output of 150W+150W by a low distortion called 0.01% or less of a distortion.

To the deck of A, the independent sound recording of the source completely different from an AUX termination to each two decks can be carried out at the deck of a phono input and B, listening to FM music.

Since the impedance of a cartridge and the impedance of amplifier match correctly, five steps can be chosen with man-month type, and four steps of input impedances can be chosen with MC type.

Substantial equipment, such as an energy sensor protection network original with a Marantz which does not spoil high S/N ratio type MC head amplifier / musicality.
