If a shock transient is occurring, the device blocks audio signal access to the amplifier. The audio signal goes through a delay line to allow processing time for detecting a shock transient and switching the shock transient audio signal out of the path to the amplifier. The delay may be variable. The device may be integral to the amplifier or may plug into a microphone jack of the amplifier, allowing use with legacy amplifiers. In an embodiment, the device may store safe, predetermined audio signals to send to the amplifier during, and in place of, a shock transient."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Amplifier-based microphone shutoff system","description":"An amplifier-resident device for protecting amplifiers and loudspeakers from shock transient audio signals from dropped microphones that may use either an amplifier control signal from the microphone ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9706301","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
