Silicon transistor power amplifier with the output of 40Wx2.
An internal specification is almost the same as SE408S.
In SE408S, the fraction which was a front-view panel is a rear panel, and it has a structure which the cover attached to the overall, and has a structure in which an equalizer board appears from the acrylics part of the center of a whole surface panel.
The rear panel serves as a design as which the radiator of the transistor also served.
The scheme called Energizer is adopted.
A printed-wiring board is in the interior by this scheme, and it is this substrate,several kinds of circuitries are prepared according to the speaker system of JBL, and it has also become an equalizer with which a dumping factor a model number -- also controls the frequency characteristic including power amplifier and a loudspeaker in an ideal property by reputting.
It is in order to insert in SE408 for having been in the enclosure backplane of some loudspeakers of JBL.
