Stereo power amplifier developed based on the
tradition of the Marantz of employing the highest power device efficiently
completely in the optimal operation and the best circuitry.
The nakedness property is sharply raised by using a super
high fT (90MHz) power transistor for the circuitry of a whole page push pull
perfect DC stream composition.
The Low-TIM design original with a Marantz
which banishes a TIM by low NFB-ization was put into practice, and AB class
output quality from Loule Bell to the maximum output has been obtained.
In the power-source part, the interference between channels and between
stages is suppressed by carrying the mass transformer which made the sub- side
the right-and-left perfect separate volume structure in power amplification
stages, and also carrying an exclusive transformer also in the voltage amplification stage.
Furthermore, powering capacity with the stable margin
is secured by reliable stream compositions, such as adoption of filter capacitor
15,000micro-Fx4 excellent in the RF property.
oxygen-free-high-conductivity-copper line of a high purity is adopted as all the
included lead wire for the drawer line of a transformer.
direct speaker termination which does not pass a contact is carried apart from
the subspeaker termination in which 1 / 2 changes are possible.
energy sensor type which detects an excessive output and always suppresses the
signal of a drive transistor in a safety area is adopted as a protection
It is the design focused on musicality which opens an output wide and does
not interrupt a performance.
High precision peek meter and a traditional sub panel are
carried in the front panel, and it has become the design stored in the mahogany
