Doug Fleenor Design's DMX512 isolators with amplifiers are considered some of the best products available for the distribution of lighting control signals. Isolators are used to eliminate ground loops and to provide protection from electrical storms, mis-connections, and equipment failures.  With the exception of our Inline Isolator, all Doug Fleenor Design isolators with amplifiers may be used as line amplifiers to boost the signal from as little as 0.2 volts to full DMX output levels. Portable, rack, and wall mount units are available.

Pandemic Availability Notice

Please Note: Due to unprecedented raw material and component shortages for finished goods throughout our industry, lead times for items that aren't currently in stock are longer than normal and cannot be guaranteed at present. Equipment needed by a firm date must be noted at time of order. While VLS cannot guarantee delivery by those dates, we will work with our suppliers to do everything possible to meet deadlines. We apologize for the inconvenience and appreciate your patience.

Same Day Shipping Cutoff time
 
(Due to Pandemic-related availability issues, this policy is currently suspended)

Online orders received by noon Eastern time typically ship the same day. If your delivery due date is critical please note your due date in the order messages at checkout, and then contact us.

Why Noon? Well, while we stock quite a few items in our warehouse, many items we have dropshipped by our vendors. They need time to process the order, so to ensure that we can get the order to the vendor and give them enough time to ship it out the same day, we need to get the order to them as early as possible in the day.

Shipping Rating

Please also note that the shipping rates for many items we sell are weight and dimension based, as this is the method that FedEx and UPS use to rate the package's cost to ship.

Returns Policy

We understand things happen and items occasionally need to be returned. To make things as hassle-free as possible, we have dedicated pages about our Returns Policy (what’s eligible to be returned) and our Return Process (how to go about returning eligible items)
