<P>PROBLEM TO BE SOLVED: To automatically adjust an attenuator of a patch destination channel in response to gain adjustment of an input port. <P>SOLUTION: The digital mixer includes a plurality of input ports whose gain is adjustable and a plurality of input channels for processing signals, and a signal of each input port is assigned to optional input channels via input patches. Each input channel is provided with the attenuator, which can control a level of the signal received at a concerned channel. The gain of the concerned input port is updated in response to gain adjustment of a certain input port (step S1), when an automatic gain adjustment function of an i-th input channel being a patch destination of the concerned input port k is activated (steps S2 to S4), the value of the attenuator of the i-th input channel is automatically adjusted to cancel a change in the gain (step S5). This processing is applied to all input channels being patch destinations of the input port k (steps S6, S7). <P>COPYRIGHT: (C)2007,JPO&INPIT |
