Gecko In.YJ2 QSC

Andi’s Top Tip – If you are looking for a replacement Gecko Spa Pack and you are finding that the product part number is not an exact match – don’t worry. What is important is the model, for example In.YJ or In.YE etc etc. The additional numbers will more than likely be an upgraded system firmware on the Spa Pack so it is unlikely you would find the exact match if you are replacing an older model. Just make sure you match the model In.YJ, YE etc etc.
