Flexible & scalable playout server system

You can do it all and more with Spectrum™ X. Combine your file, baseband and transport stream ingest with integrated channel playout capabilities. You’ll have graphics, branding, DVE and live switching of baseband and compressed IP sources all in one server. Store and deliver your channels based on your business needs with Spectrum X.

The server systems come in several sizes to accommodate small to large channel counts and can adapt to storage capacity needs.

Integrated channel playout in all systems

Integrated channel playout functionality is present in all Spectrum X products. Signal chains that used to require multiple pieces of equipment can be collapsed into a single Spectrum X server.

Reach new levels of efficiency

Integrated functions are onboard graphics, master control switching, playout automation, subtitle insertion, audio mixing, delay service, audio watermarking and much more. 

Transition to IP workflows

By integrating SDI and IP I/O on the same chassis, Spectrum X also eases the migration to IP playout workflows, allowing broadcasters to transition away from baseband at their own pace.

Production & playout with Spectrum

The software-based server supports a broad range of SD and HD formats up to 1080p (3G) and ultra HD. You’ll get a flexible system that allows you to easily expand storage, add new codecs, CiaB functionality IP I/O and other advanced features. Move at your own pace when migrating to IP playout workflows by integrating SDI and IP I/O on the same chassis with Spectrum X.
