AJA HELO Plus 4-Channel Audio Option License

As shipped, HELO Plus streams and records a single stereo pair. This license expands that to four channels, two stereo pairs, which is what a dual-language job needs: an ice hockey game can carry the home commentary in English on one encoder and the away commentary in French on the other, from one box.

It also changes what the unit can pull from an SDI feed. With the option active, any of the four embedded stereo pairs (channels 1 and 2, 3 and 4, 5 and 6, 7 and 8) can be selected as either of the HELO Plus audio sources for streaming and recording, so a mixed program feed with multiple audio services no longer needs an external de-embedder. The feature was introduced with HELO Plus v2.0 firmware and can be purchased in the unit's web UI or applied as a license key.
