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
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.
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.
