The Spectra SP-ASI is an Entry-Level MPEG-2 encoder with ASI output. It is ideally suited for very cost-sensitive applications where good picture quality and easy simple controls are required.

The unit includes analog inputs for left/right Audio and differential SUB-D audio, composite and Y/C Video inputs and RS-232 monitoring output. The transport stream is available at double buffered ASI outputs.

The Spectra ASI encoder is housed in a rugged compact 19" 1U rack chassis for any Environmental Conditions.

The SP-ASI is the perfect component for any digital headend multi-channel application, mobile contribution such as sport and news gathering via microwave or satellite links and any other broadcast and professional application where quality but also budgetary considerations are important.
