SPL IRON Mastering Compressor

The SPL IRON (Model 1520) is a completely new and unique Mastering Compressor crafted by SPL designer Wolfgang Neumann, featuring a tube architecture and a Vari-Mu-operational principle, built atop SPL's now-famous 120 Volt Rail technology found in their best offerings.

So, to be clear - The SPL Iron is not a copy or tribute piece; IRON is something completely new. So, buckle up... Right out of the gate, no less than SIX rectifier settings for the detector circuit are available, as well as four distinct filters present in the side-chain signal path. Tube Bias settings (Low, Mid, High) are available per each channel. As if these features aren't enough, they are joined by features such as "AirBass" and "Tape roll-off" as additional tibre-shaping tools. The controls for Attack, Release, Ratio, Input and Output are designed as a rotary switch, as it is typical for effect units to be used in mastering.

One unique feature to IRON is the "Audition" function which allows you, once engaged, to set a time interval at which IRON will engage the bypass relays so you can have a truly objective perspective on how IRON is compressing and coloring the audio. No more moving around to patch in and pull the patch cables - or doing anything other than simply listening. Well done, Wolfgang.

IRON is a wonderful and complex sounding compressor which can provide a multitude of approaches to applying finishing touches individual tracks, subgroups, or full mixes to cement the work. And as the name should imply, there is quite a bit of heft and weight that IRON can apply to your sound.

Thus, the IRON combines not only the sonic virtues of legendary vintage tube compressors with the advantages of the High Dynamic 120 V operating voltage in a single unit. It also sets a new benchmark in terms of tube compressor technology, with the innovative implementation of a parallel dual-tube circuit.

What We Think

"I was recently introduced to the SPL IRON Mastering Compressor by Sascha from SPL. It's physical presence is commanding to say the least. IRON is a bona fide compression toolkit which features compression and tonal shaping tools never before implemented in a mastering quality compressor. Granted it may take a little while to fully explore all of the features and sonic possibilities that the SPL IRON is capable of, but thankfully, it sounds phenomenal at it's most basic settings. If maximum tweakablility is your thing, then IRON is your compressor."
