SMProAudio Q DI, a compact Value series of audio products has received a major revision in terms of appearance and performance. Upgraded to include SM Pro Audio’s E-Series circuit design improvements, the Q-DI delivers high quality audio in a stylish compact format. E-Series circuit design, component selection, and manufacturing offer an additional level of quality to the already successful DI4V. The unit is housed in a stylish extruded aluminium external chassis that can be rack-mounted using SM Pro Audio’s RM-1 single unit rack-mount adaptor. One unit can be mounted in the centre of the rack, or two units side by side. Robust connectors are provided for all inputs and outputs.
