The unit runs at 115, 220, or 240 volts, selected by a voltage selector on the rear panel.
All power supply electrolytics have been replaced and the unit has a new fan. All settings are stored in battery backup RAM; the unit has a fresh battery. All the internal ribbon cables have been replaced with new ones. The front panel is in good condition but the corners and rack holes have some dings and rash.

AMS effects units show up at least once a week on ebay. Why should you buy yours from Studio Electronics?
1. Reburb and testing: every AMS that we sell has been been thoroughly serviced and tested. Any marginal components are replaced and the 10 or so all important ribbon cables are replaced with new ones. The unit is thoroughly tested and then run for several days. The power supplies are thoroughly serviced and checked. (Normally we charge $800 for this service.) An AMS purchased from us has been given a new lease on life and is likely to be trouble free for many, many years.
2. Marginal parts: Since we refurb so many AMS’s, we know what to look for. If the fan runs slow we know the unit will run hot, and we replace it with the exact same, quiet running part. If a switch is bent or noisy or if pot is faulty, we replace it. If an PC card connector is worn, we replace it. If a fastener is missing from the top or bottom cover, we replace it.
3. Function and specs test: most AMS sellers on ebay don’t check all the features of these machines. Before listing this DMX on ebay we checked lock in, loop editing, the mix functions, etc.
4. Support: if something goes wrong, we’ll get you taken care of quickly. Our shop stocks hundreds of spare AMS boards and keeps several working units on hand. Next week or next year, if there’s a problem, call us. We’ll be glad to help you out, and will do so quickly.
