Very Nice JBL Synthesis SDEC2500 digital EQ. This digital equalization unit is an excellent choice for anyone that wants to dramatically improve the sound of their home theater system. Set however does require some skill, a lap top and the JBL SYNTHESIS calibration kit. Kit not included. This item is meant for the very serious enthusiast or a professional. Unit was pulled from a system and replaced with a 4000. Unit powers up and was working at the time of the swap. But since it is used electronics it is being sold as is. THIS ITEM WILL NOT BE RELISTED. If there are no offers or offers, then it will be pitched. So if you want it, buy it, offer on it, offer or do something other than watch because it will not likely come back around. Happy offerding!!!!
