I recently purchased this Crestron AV2 processor.  I had plans to replace the smaller processor in my home system so I replaced the aging power supply capacitors in the 24volt supply and also replaced the memory backup battery.  I decided to go a different direction on my system so I am selling this unit.  Please feel free to let me know if you have any questions.  The unit has been tested and functions well but due to its age it is being sold as-is with no returns.
