IRON
An amazing sound from an all-original analog design
When SPL released the IRON mastering compressor, it became an instant icon. Their goal was to create a compressor that provided a pleasant, melodic-sounding, transparent compression, inspired by the vintage compressors of the radio era. But, they wanted it to be versatile enough to adapt perfectly to the needs of modern mastering studios. The resulting 25 lb, 4RU tube compressor was an immediate hit in top mastering studios around the world.
Inspired by tube classics, packed full of 21st century innovations
The IRON set a new benchmark by taking the sonic virtues of legendary vintage tube compressors and adding on modern innovations, including a parallel dual tube circuit, rectifier mode switching, flexible attack and release settings, and a High Dynamic 120V operating voltage.
Like two tube compressors in one
Unlike traditional Vari-Mu designs, which use a single tube for compression, IRON employs a unique dual circuit topology. A specially designed Mu-Metal iron transformer splits the signal between two distinctly different tubesāa 12AX7/ECC83 and a 12AU7/ECC82āeach with a slightly different compression curve and feel. These two separate tube compression circuits are run in parallel, and then recombined to taste for a uniquely flexible approach to tube compression.
Far more control than any vintage Vari-Mu compressor
The IRON includes sidechain filters, and Attack and Release parameters that have six different settings ranging from Slow to Fast. These times vary according to the Rectifier circuit selected. Each of the six different Rectifier settings make use of different diode combinationsāGermanium, Silicon, LED, and mixed for even more tonal variation. This added control means that mastering is not the only domain where the IRON sets new standards. It can also be used to process subgroups or individual signals, like vocals, bass, guitar, strings and more.
True analog modeling with the power of TMT
The SPL Iron is a TMT plugin, based on the patented Tolerance Modeling Technology by Brainworx. TMT gives you the most realistic analog sound in the box by offering multiple plugin channels with realistic analog tolerances in the components of the circuit modeling. Additional digital-only features include a monomaker, stereo width control, MS processing and more, making the plugin even more powerful than the original.
