Orban Optimod FM 8500-FM/HD Digital Processor (with HD output)

This allows you to use the 8500FM's's built-in stereo encoder and composite limiter to drive the analog FM transmitter, ensuring no-compromise analog-channel loudness. If you defeat the 8-second delay, you'll find that the 8500's base throughput delay has decreased by almost 4 milliseconds compared to the 8400. This makes off-air headphone monitoring even more comfortable for talent. Of course, we've retained the 8400's "headphone monitor" output option, which now has a negligible 2-millisecond delay regardless of the processing structure on-air. We've also added the "ultra-low-latency" structure first introduced in Optimod-FM 8300. This structure yields about 3 milliseconds of throughput delay at the expense of lower loudness.

If you choose to use the 8500's superb DSP-based stereo encoder and composite limiter, be assured that they deliver an FM analog signal that is always immaculately clean and perfectly peak limited, with full spectral protection of subcarriers and RDS/RBDS regardless of the amount of composite limiting.
