OPTIMOD 8700i LT is a light version of Orban’s flagship processor 8700i. It offers the same versatile five-band and two-band processing for both analog FM transmission and digital media (DAB+/HD Radio/Streaming) This 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 OPTIMOD 8700i LT can be also upgraded later on to a fully-featured OPTIMOD 8700i. This upgrade will add the DANTE AoIP interface, the Streaming Monitor Output and the Xponential Loudness™ algorithm.

OPTIMOD 8700i Audio Processor with Xponential Loudness™

For both analog FM transmission and digital media (DAB and HD radio/streaming), the 8700i provides 2-band as well as 5-band audio processing structures

With its Multipath Mitigator phase corrector, multipath distortion can be reduced without compromising the stereo separation. Orban’s MX limiter technology lowers distortion, improves transient punch, and minimizes preemphasis-induced high frequency loss. Other features include the Dante interface which provides dual-redundant AoIP with AES67 support, digital MPX interface, a built-in streaming server for monitoring purposes, dual redundant power supplies, and safety bypass relays for carefree 24/7 operation.

The new XPN-AM Audio Processor is based upon an AM-optimized version of Orban’s MX limiter technology that was first introduced in the Optimod-FM 8600. This revolutionary limiter technology provides an unprecedented combination of loudness, cleanliness, crispness, speech intelligibility, and coverage. Additionally, XPN-AM’s design incorporates everything Orban has learned in 42 years of AM processing experience, starting with the original Optimod-AM 9000 back in 1977. 


Compared to other AM processors, the ability of Orban’s XPN-AM processor to generate greater density with lower distortion can significantly reduce power consumption with Modulation Dependent Carrier Level (MDCL) equipped transmitters. Early field tests show upwards of a 20% power savings is achievable. Depending on MDCL transmitter settings, broadcasters can maximize coverage, minimize power consumption while keeping existing coverage, or split the difference.
