Production Wireless Guide
Step 1: Run an FB-460B scan at your shoot location 1–2 weeks before production.
Step 2: Check the Channel Map tab. Green channels are open. Red channels are occupied by broadcast stations — do NOT use these.
Step 3: Leave one guard channel above and below each occupied channel.
Step 4: Assign your wireless mics to open channels, spacing at least 200 kHz apart for digital systems or 600 kHz for analog.
Step 5: Verify with a local RF scan on production day. Conditions can change.
