120V Rail Technology:
120V Rail Technology is developed and manufactured to run on an operating voltage of 120 volts, which corresponds to twice that of discrete operational amplifiers and four-times that of semiconductor operational amplifiers. Technically especially in terms of dynamic range and headroom and sonically especially in reproducing the finest details and delivering a totally relaxed sounding audio experience. Music sounds absolutely natural and hearing fatigue is drastically reduced.
Features:
-
Variable bias tube compressor
-
Parallel dual tube circuit
-
Tube selection and pairing with Weigl Roe Test
-
Specially conceived Mu-Metal iron transformers
-
Feed-forward resistive vactrol-opto-isolator
-
Six different Rectifier settings available
-
Sidechain that allows you to choose between Off, four sidechain-filter presets or an external sidechain signal.
-
All functions can be adjusted via switches or, in the case of the Threshold, with a detented potentiometer
-
In Link mode, the Threshold, Tube Bias, Attack, Release, and Rectifier parameters, as well as the Sidechain EQs, are controlled with the right side (channel 2) of the unit.
-
Additional passive 120V equalizer with two presets
-
High Dynamic 120V operating voltage
-
Auto Bypass mode

Made in Germany
As a mastering compressor, IRON is inspired by the legendary vintage tube compressors à la Fairchild, Collins or Gates and has been developed in a way to give modern productions more energy and power with the advantages of the 120V technology.
Input & Output
Input and output levels are switchable in a control range of +/- 12dB. An increase of the input level leads to more intensive compression. When mastering full scale material, the reduction can be useful. The output is used to adjust the level ratios of input and output.
Attack & Release
The time parameters Attack and Release are switchable in six steps from Slow to Fast. The times vary depending on the rectifier circuit selected.
Side Chain EQs
With the side chain EQs, compression can be focused on frequency ranges. In addition to an inserted EQ, there are four internal EQ presets with a partly complex frequency response.
Rectifier
The tube stage is controlled by a rectifier circuit. There are six diode control characteristics generated by germanium, silicon and LED diodes or combinations thereof.
