The present invention comprises a system that provides a convenient and easy-to-use means for controlling audio input and output for recording. The system includes a first input adapted to receive a high fidelity microphone such as a low impedance microphone, and a second input adapted to receive a musical instrument. The system also includes at least two outputs, each adapted to transmit analog signals to an input of a sound card (30) of a computer (20), and electrical circuitry coupling the inputs to the outputs. More specifically, the system further comprises at least one additional input adapted to receive analog signals from an output of the sound card (30) and at least one additional output adapted to transmit analog signals to a receiver. The electrical circuitry couples the additional input to the additional output, and is operable to transmit analog signals from the first and second inputs to the receiver and to the input of the sound card (30). The electrical circuitry is further operable to resistively isolate the analog signals transmitted from the output of the sound card (30) from the input of the sound card (30).
