The USB-2CH from After Later Audio is a stereo AD/DA converter in Eurorack format. The module is connected to the computer via the more stable USB-B connection and thus enables the integration of a stereo signal in the modular system and recording in the computer. You can select whether the module works in standard or insert mode using the rear panel Jumper . The former allows a stereo signal to be sent and received via USB, while the insert mode sends the stereo signal to the computer and outputs a copy at the outputs. This is useful if the recording track is required elsewhere in Patch . The USB-2CH can be combined with the ALA modules Bartender, DVCA, Cast Iron, and Mingles, among others. By connecting the rear input and output pins, the sound is sent/received to the next module.
