Customers often contact us to find out if their Arrow audio interface is able to send control voltages (CV) directly out to external analog synthesizers.
For this to work, the line outputs must be DC coupled. Luckily, almost all of our Apollos including Arrow do have DC coupled line outputs that are suitable for this application.
The only Apollo that does NOT have DC coupled outputs is the original Apollo (silver), currently named Apollo Firewire.
All other Apollo models feature DC coupled outputs and are suitable for sending control voltages to your external analog synthesizers.
