SPL-IRON

The IRON Mastering Compressor is a variable-bias limiter/compressor from the basic concept. Through the integration of new technologies, this concept gets significantly improved.

IRON works on the principle of the bias controlled remote cutoff tube. Sharp-cutoff tubes with a steeper characteristic are parallelly connected to these.

Depending on the level of the signal amplitude, one or another tube is in charge for signal processing/limiting. The positive result is a well-balanced sound and more controllable settings of the parameters.

All four tubes in the IRON are a specially matched set to the overall system.
