Abstract: A digital signal processing amplifier device has a programmable “drag and drop” digital signal processor (DSP), a power supply connected to the DSP and a modular or integral audio amplifier, all housed in a chassis. The amplifier is able to amplify and transmit a signal from the programmable DSP to an output device. To create an audio design, a user, via means of a computer which is in communication with the programmable DSP, may select and assign audio elements to create a virtual audio design. The computer and related software create a set of instructions from the virtual audio design and the instructions are transmitted from the computer to the programmable DSP. The DSP executes the instructions to modify an input signal to provide an output signal, and the output signal is then transmitted by the amplifier to an output device.
