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.
