Yamaha recently released new versions of firmware for our PM5D and DSP5D digital mixing systems. The new firmware brings the PM5D up to Version 2.27 and the DSP5D to Version 1.27.
Your current versions of Studio Manager (2.3.1, 2.3.0) and Editors (2.2.5) will still work with your PM5D and DSP5D unless you're upgrading from firmware Version/s 2.22/1.22 and lower.
Instructions and information on properly upgrading your unit can be found online via the links below. Be sure that you've backed up your PM5D and DSP5D before loading the new firmware as your current data will be intilized during the firmware update process.
