With new features like a fine TRIM control, switchable microphone input impedance, signal presence LED, intelligent protected switching of front combi-XLR input connector and Neve’s clever Audio Processing Input design, the 1073LB takes your 500-series rack to the next level. Simply install into an empty slot in your compatible 500-series rack, connect your microphone or line level signals and inject that legendary sound into your audio creations.
