DiGiGrid Q features 1/4-inch and 3.5mm outputs, so it can accommodate any headphones up to 600ohm. It has four monitoring input options to suit all users: XLR for professional use, Ethernet to connect to a SoundGrid network, analog for consumer audiophiles, and Bluetooth for a fun and fast experience working directly with your digital music collection. The interface integrates seamlessly with any other SoundGrid product, should you wish to expand your network and add a high-end headphone amp to your studio's live room, vocal booth, control room, or live FOH or monitors setup.
