Optimod-FM 8600 HD
Optimod-FM 8600 is Orban’s flagship processor and the next step beyond the OPTIMOD-FM 8500. Featuring versatile five-band and two-band processing for both analog FM transmission and digital media, the 8600 provides the industry’s most consistent sound, track-to-track and source-to-source. This consistency allows you to create a sonic signature for your station with the assurance that your signature will stay locked in, uniquely branding your sound.
The Orban Optimod-FM 8600-HD has the same processing technology as the Optimod-FM 8600. The HD version comes with a digital output for digital signal such as DAB or FMeXstra.
Summary
Dramatically improved peak limiter technology decreases distortion while increasing transient punch and high frequency power handling capacity. Compared to the FM-channel peak limiter in Optimod-FM 8500, the new peak limiter typically provides 2.5 to 3 dB more power at high frequencies, which minimizes audible HF loss caused by preemphasis limiting. Drums and percussion cut through the mix. Highs are airy. “Problem material” that used to cause audible distortion is handled cleanly.
While this design offers about the same loudness as 8500 processing, its main goal is to make FM analog broadcasts more competitive with the cleanliness, punch, and open high frequencies of the digital media against which FM analog transmissions now battle. The FM loudness wars were so 20th-century; in the 21st century the new foe is digital media. Thanks to its fresh, crisp sound, the 8600 helps level the playing field between analog FM and its ever more aggressive digital-only competitors.
Like the 8500 the 8600 offers parallel processing for digital channels like HD Radio that simulcast the program material on the FM analog channel. Except for the AGC, the analog FM and digital radio channels are independent and separately adjustable. The digital radio channel features a new peak limiter that uses some of the same new technology as the peak limiter in the FM analog processing channel.
The 8600 offers 8500-style processing too. This allows broadcasters to run favorite 8500 presets if they wish. Because the input/output delay of the new peak limiter is too long to permit talent to monitor off-air on headphones, 8500 processing is useful for remotes and outside broadcasts where off-air headphone monitoring is desired and the 8600’s low-delay monitor output cannot be brought to the talent.
Some customers in countries enforcing ITU-R 412 MPX power limits have requested the ability to apply MPX power gain reduction after the clippers so that the texture of the processing can include more “clipper sound.” The 8600 offers this option.
