DC-Coupled Outputs - CV/Gate Voltage Control
Most audio interfaces are traditionally designed with what is called 'AC-coupled outputs', where capacitors are used to filter out any extreme low frequencies.
Whilst these frequencies are generally considered undesirable for audio - eating into headroom and potentially causing damage to other equipment - one instance where DC-coupling remains desirable is the world of modular synthesizers, where static or slow-moving signals are used for control over various parameters such as pitch note values or LFOs.
On selected RME interfaces line-level outputs are fully DC-coupled, allowing for the sending of control voltages (CV) or Gate information to modular synthesizers (such as the popular Eurorack and Moog/MOTM/Synthesizers formats) and other studio hardware.
