The SW200 LPAM Audio Processor

Schlockwood's SW200 is a comprehensive audio processing system for Part 15 Low Power AM (LPAM) broadcasting and ham radio applications.  Functions include gated-AGC, variable pre-emphasis, multiband com-pression/limiting, program equalization, asym-metrical peak control and a sharp cutoff filter.

The 2021 production run of SW200s has sold out.  We normally make only one run a year, but because this last run sold out so fast, we are planning a second one.  Look for availability in November, 2021.

Thanks for your interest in the SW200!

Please note:

We welcome factory-direct sales of the SW200, and will be instituting changes in our sales strategies that will make direct sales easier.  In the meantime we strongly encourage purchase through our eBay listing, which will be linked here when active.

As the public turns increasingly to Internet sales with home delivery, the instance of 'porch piracy' has become rampant in many areas.
  eBay purchases feature eBay Buyer Protection that indemnifies both buyer and seller from most shipping losses.

All orders placed directly with the factory will be promptly quoted individually, and must bear the added modest expense (just our cost) of insurance for the full amount of the sale and a signature upon delivery.  Thanks for your understanding toward our mutual protection.
