The TDX-1 is a compact and powerful DSP based audio-processing unit, ideally suited to fixed
installations and live applications, where it combines the functions of multiple conventional products
in a compact 1U of rack space. For ease of use the TDX-1 is supplied pre loaded with the most
common configurations of our product ranges that require or benefit from the use of a system
