IMPROVEMENT TO THE CONTROL UNIT OF VEHICLE AUDIO / VIDEO DEVICE

摘要

PURPOSE: To easily select the function of a desired level by automatically simulating the present function through the emphasis and/or mutual attenuation of the function between setting levels and identifying the function. CONSTITUTION: The new operation of function selection control 6 guarantees a low pitch extent level adjusting function and a high pitch extent level adjustment function, and an appropriate program positioned in a control unit 10 operates on an adjusting circuit 12. A user recognizes the function and can change the pitch extent level between the levels which are set by adjustment control 5. At that time, the present function can automatically be simulated through the emphasis and/or the alternate attenuation of the function between the setting levels and a simulation means 11 makes the user identify the function. The means 11 controls reproduction 14 and 16 and the setting level and the selected function can be recognized by sound.
