The products shown here are being manufactured, sold and supported by ADD COMMUNICATIONS in Sydney – Australia.

This is an operation independent of Emona Electronics Pty. Ltd. and Emtron Industries, Sydney.

The reason our product is branded Emtron is our long association with Emtron Industries, in designing, manufacturing and servicing the DX- range of linear power amplifiers, but these are two completely different operations.
