Episode notes
Peak Limiting Before Compression
- Spectra's C610 limiter separates peak limiting from compression so peaks are removed before average-level compression begins. This prevents pumping and lets you raise average level without distortion for more perceived impact.
610s Dumped Then Rescued
- Thousands of 610 units were sold to radio stations and cable head-ends because the limiter improved fidelity and protected transmitters. Many early units were discarded in the 1990s until engineers rediscovered their headroom benefits.
RMS Clipping Preserves Harmonics
- Spectra circuits clip by RMS (power supply saturation) rather than hard peak clipping, preserving harmonics and producing a musical overdrive. That RMS clipping explains the desirable 'fat' character when pushed hard.
