Prime brings the sound of a live acoustic space to your productions using six prime-numbered early reflections. Based on a classic studio technique attributed to Steve Albini, Prime carefully places staggered reflections to create both stereo depth and a sense of physical space—without relying on a conventional reverb tail. WHAT YOU'RE HEARING Prime simulates a Live Room environment with Untreated Wood surfaces. Six short reflections are distributed across the stereo field, giving your sound a sense of dimension and placement. TRY IT ON • Drums: Add the feeling of a live recording room to close-miked sounds. • Vocals: Give a dry recording a sense of space without a long reverb tail. • Guitars & Synths: Add subtle stereo dimension and acoustic character. PRO TIP Prime outputs 100% reflections when switched on. Place it on a stereo effects return and blend the return with your original track. LOVE PRIME? EXPLORE PRIME PRO. One room is just the beginning. Prime Pro unlocks the full acoustic engine: • 7 room environments, from Closet to Arena • 8 surface materials, from absorbing Fabric to reflective Metal • 56 unique combinations of space and character From intimate recording spaces to massive industrial reflections, Prime Pro gives you complete creative control.
