Bedrock Elite i9
Class 1 Sound Analyzer
Compliance-grade Class 1 precision with premium 1/2" free-field capsule (48 V phantom powered). Octave analysis, FFT, statistical logging, and environmental monitoring—configured and ready. No hidden upgrade costs.
Includes the Bedrock Elite Analyzer. Reporting and analysis software of this kind is typically sold separately, often for thousands of euros. With a Bedrock Elite instrument it is included — every module, no unlock fees. Try it in demo mode before you order, no serial needed. See the Analyzer →
The i9 is designed for professionals who expect questions and need analytical flexibility without configuration uncertainty. Fully equipped delivery avoids feature negotiation and upgrade dependency.
About this product
The Bedrock Elite i9 delivers Class 1 precision with the complete feature set professionals require—without the typical industry games of module restrictions and unlock fees.
Professional-Grade, Complete Delivery
Every i9 includes STIPA and Full STI measurement, octave analysis, statistical logging, and environmental monitoring. We don't believe in shipping instruments with artificial limitations just to create upsell opportunities.
