The level adjustment, the signal processor, on the AV central processing unit

摘要

It designates that it does mechanical in the operating member the adjustment of the output level which it cannot actualize, with intuitively know operation as topic. As for AV processor 30 of this invention, on touch panel TP, paralleling to the specified track 62, output level GUI it indicates adjustment possible hueda F by making handler move 61. When the optional position on tracked 62 with the operation of the user is appointed with the point, to the optional position PB which is appointed from the portable start position PA which is in the position of handler 61 before the particular appointing, spending the movement requirements time which is decided beforehand, it makes handler move 61 at fixed speed.
