OUR PART # SPLIRON
The SPL IRON ("Model 1520") is a Mastering Compressor designed by SPL designer Wolfgang Neumann, featuring a tube architecture and Vari-Mu-operational principle, built atop SPL's now-famous 120 Volt Rail technology found in their best offerings. 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 "AirBass" and "Tape roll-off" as additional timbre-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.
