ABSTRACT:
An analog-digital interface device is provided, which is configured to be housed within or removably coupled with an analog mixer, to thereby form a digital-output analog mixer. The analog-digital interface device includes analog-digital conversion circuitry and digital transmission circuitry that convert analog audio from the analog mixer to digital format for transmission along a digital transport interface to an external digital computing device, such as a PC or MAC computer. In one embodiment, the analog audio can be tapped from any one or more points along a signal path of the analog mixer and sent to the analog-digital interface device. In another embodiment, the analog-digital interface device is further configured to receive digital signals back from the external digital computing device, convert them to analog signals, and return them to the analog mixer at any one or more points along a signal path of the analog mixer.
