EXCELLENT CONDITION These units have VERY FEW HOURS on them, as I only used them for a 2 month project and then placed them in storage back in 2012 (and they have been in storage ever since). They never left the house and are in perfect working condition. Very little wear and tear (see photos).
Comes with the user manual and power cord.
Similar unit selling on for $942 CDN + shipping:
I have two of these units available. Selling for $600 CDN each.
Will ship anywhere in North America (buyer pays $20 handling each + shipping)
Please see my other listings for more equipment, lights, cables and graphic EQ’s / RTA’s
