PURPOSE:To provide the acoustic effect adding device for providing acoustic effects, which does not depend on the flow of signals, when using the device while performing cascade connection to digital signal processors(DSP). CONSTITUTION:At output terminals O1 and O2 for outputting acoustic signals to which the acoustic effects are added, to the outside, digital audio output circuits 3 composed of logic circuits are provided for electrically disconnecting external circuits connected to the output terminals O1 and O2 and the internal circuits of the devices so as not to generate the trouble of short-circuiting a power source and the ground even when the plural output terminals O1 and O2 are connected in common, and an output can be selectively extracted from any one of DSP even without providing selector circuits at the output terminals O1 and O2. |
