Audio:
Q) Does Spectra support Dolby Atmos audio?
A) With a 16-channel audio license, it can support the 12 channels required by Dolby Atmos. However, Spectra cannot transmit the Atmos audio metadata.
Q) What audio codecs does Spectra support?
A) PCM (uncompressed) which has a per-channel bitrate of 768kbps, AAC (128kbps), and GSM and CIF codecs at the low end. PCM and AAC allow separate channels, GSM and CIF are mono codecs that mix all channels together. (If set for 6 channels, for example, the output of GSM and CIF encoding would be 6 channels in which each channel is the sound of all 6 channels mixed together.)
Troubleshooting:
Q) Why is the Encryption tab blank?
A) Encryption requires an additional license. Please contact Streambox Sales: sales@streambox.com
Q) Why am I seeing a blue screen with No signal displayed?
A) Check the Source page to make sure the appropriate Capture Driver/Source is selected. Also check the Features page to ensure the appropriate license is active.
Q) Why is my source not on the Capture Driver dropdown (on the Source page)
A) Spectra only polls available sources when it first loads so it is best practice to load Spectra after you source is loaded (e.g., Premiere Pro, DaVinci Resolve, Media Composer) or plugged in (e.g., Ultrastudio Recorder). Hardware with multiple inputs will list them separately, e.g. the Decklink 8K Pro has 4 inputs and will list 4 inputs to choose from, so be sure to try them all.
