Stereo power amplifier designed on the assumption that cooperation with SC-5 and exclusive battery unit bb-5.
Even if the impedance of a speaker falls, the low-impedance drive design is practiced so that sufficient electric current can be supplied. Thereby, also in combination with the speaker of the low-impedance that an Integrated Amplifier will be brandished, the correspondence of a margin is always realized and powerful drive capacity has been acquired.
To input buffer amplifier and the power amplifier first rank, DC clean drive is possible.
Ability can be demonstrated by the combined use with battery power-source bb-5 for exclusive use.
A total of six NEW HDAM of a four-layers substrate structure is used.
This evolved further the high-speed voltage amplification module and HDAM by the original technology of a Marantz, and has gained the accelerating of a circuitry, the stabilization, and high S/N.
The output stage is using the RF large-sized power transistor by the parallel push pull.
The large-sized toroidal power transformer and the low double foil chemicon are used for a power-source part.
What can be set up at a 1dB step is adopted as an Attenuator.
High vibration suppression nature is secured to the chassis construction by the copper plating zinc die-casting chassis and the aluminum plate-mill panel.
