SP25 Prisma, SPA25 Prisma, and SC15 Prisma MK2 October Updates
Prisma firmware updates described below will be released this week, 16-18 October, for SP25 Prisma, SPA25 Prisma, and SC15 Prisma MK2.
Change logs are available below for each model, but in general, the update adds features and provides bug fixes, while noting the following:
The update for SC15 Prisma MK2 is for that version only, and not the original version, as it primarily effects the DSP systems added to the later model.
The SP25 Prisma and SPA25 Prisma updates add support for Control4, Crestron, and ELAN (Nice) control systems, with the drivers available under the Support tab of each of those models product pages or on the Downloads and Documents page of the website.
The Prisma firmware update is automatic, being automatically downloaded and installed into any internet connected Prisma device.
To confirm that the firmware update has taken place, go to the “What are the latest Prisma firmware versions?” FAQ page at this link.
If the update has not taken place in your unit shortly after the date shown in the latest firmware update table, you can manually initiate an update by selecting “Restart” in the settings menu or by rebooting by turning off and then back on using the AC mains power switch on the back panel.
This will cause the Prisma device to do a full systems check, including checking for any new firmware updates, which will be installed if any are available.
Do allow a good ten minutes (it should not take this long, but just to be on the safe side) for this full process to take place, being sure not to use the component during this process so that it can be completed without interruption.
If for some reason it is interrupted and gets stuck, simply restart, or reboot again.
Roon Ready certification for SP25 Prisma and SPA25 Prisma models is next up, noting that due to improvements being made to testing procedures and the relocation of testing facilities after Harmon’s acquisition of Roon extended delays in the testing and certification process are being experienced. We have been informed that the process for both models is now fully underway and will keep you informed of all progress as we continue work to have it available as soon as possible.
