Description
 
Single channel amplifier which carries a volume.

Three input terminals including compact-disk direct position are carried. Moreover, though it is small, it is M-50. Two speaker interconnections are possible at one set.

Carrying the high cut row cut-off filter, and using it as exclusive amplifier of a Sub woofer with combination and a noise cut of Dolby surround are possible.

A 2t griddle is used for a sole plate, and the thing made from a sintered alloy used by A-10IBM PCN II and A-10dBASE III is adopted as an insulator.
