Marantz SR-1100 49,800yen(around the 1980 time)

audio-video surround amplifier which carries the Dolby prologic.

The Dolby prologic circuitry is carried and, in addition to two fronts, the power amplifier part has 4 amplifier stream compositions of rear 1ch and center 1ch.
Two speaker output-terminals of rear are carried, support five speakers, and support the Dolby prologic system without extension of the amplifier for centers as it is.
Moreover, the center channel can choose the phantom when not using Normal for small speakers, the wideness for the speakers more than a medium size, and a center speaker.

Two kinds of surround modes, a matrix and a hole, other than the Dolby prologic are carried.
The matrix utilizable for the hole mode which adds the reverberation of a concert hall to the usual 2ch sources, such as compact disk, the live source, a sport of LD, etc. is carried.

The super bus circuit which is a graphic equalizer type bass reinforcement circuitry is carried, and a bass play can be improved.

Three audios and the contact button of four audio videos are carried.
Moreover, the S terminal is also carried in LD, VTR1, and TV.

The side panel of the vibration proof structure adopted as PM-80 etc. is adopted.
Moreover, two colour variations, black and gold, occurred.

Learned pre coded type remote control is attached, and the elementary operation of ST700BS or other Marantz products is possible. Moreover, the remote control code of television by other manufactures or the elementary operation of a videocassette recorder is registered.
