Compatibility Hint

This product has been designed as a replacement of the following two units:

- GV202 (dual splitter with TTL Input)

- GV203 (dual splitter with HTL input)

The new GV204 model is fully compatible to the previous models with all functions,

connections, dimensions and technical specifications. Merely the successor model provides an
additional DIL switch to set the input format to either TTL or HTL level, which allows to replace
both parent models by just one new model.

Moreover, GV204 provides a few technical upgrades (e.g. higher frequencies), resulting in

increased quality without affecting the compatibility.
