PURPOSE:To allow the user to adjust the separation preferably by designing the separation of two channel information sources for recording free of adjustment to obtain a natural spread of sound field in terms of hearing feeling. CONSTITUTION:Two channel L, R information of a record disc signal source 1 as an analog recording medium is applied to one input of adders 2, 3 and also to level controllers 5, 4. A control signal adjusting externally the attenuation factor is applied to the controllers 5, 4, and each channel information adjusted for the level by the controllers 5, 4 is applied to the other input of the adders 2, 3, and the output of the adders 2, 3 is applied to a disc recorder 7 for recording. In case of reproduction, the adders 2, 3 and the level controllers 5, 4 are used, allowing the user to adjust freely a natural spread of sound field in terms of hearing feeling. |
