High quality Dynamic Vocal microphone by Audix, model OM 1 with standard XLR cable. Vintage 1980s model, very rare. Tested and working, appears to have hardly been used. Manufacturer description: "The OM-1 is characterized with an elevated mid range for sharp, crisp vocals along with a slight bass proximity to enrich the over-all sound. The mic also handles very high SPL levels without distortion, has superior off-axis rejection and supplies maximum gain before feedback. A spring steel grill and all brass construction provide rock solid durability."
