SPL Iron Mastering Compressor v2 - All Black  From SPL

IRON v2 sports three new features

1. Side Chain Insert

Balanced Side Chain Inserts are now standard using send and return XLR sockets instead of Side Chain Inputs with TS sockets only. That makes it easy to add an equalizer of choice into the control voltage path to create individual filter curves to focus the response of the compression to certain frequency ranges.

2. Side Chain EQ filter curves

IRON v2 features changed EQ presets which makes operation faster and more intuitive.

Position 1       Off

Position 2 EQ1                  Lowpass

Position 3 EQ2                  Highpass

Position 4 EQ3                  Bandpass

Position 5 EQ4                  Special (special filter curve by Developer Wolfgang Neumann)

Position 6 Ext.                  Create individual filter curves with an external EQ

3. Tubes

IRON v2 is now equipped with Wathen CryoTone™ 12AX7-WCM Long Plate tubes.

These are the perfect match to the parallel connected 12AU7 tubes in its circuit, which results in an improved sound and longevity.

The IRON mastering compressor is not a copy of a classic unit, but rather an original concept in itself. Our goal was to conceive a compressor that provided a pleasant, melodic-sounding, transparent compression, inspired on the vintage compressors of the radio era. And we wanted it to be versatile enough to adapt perfectly to the needs of modern mastering studios.

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.

• 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
