SPL DynaMaxx RPM RackPack Module Details

The SPL DynaMaxx RPM, part of the SPL RackPack modular system series, is probably is the most consequent interpretation of a “set & forget“ compressor concept. In keeping with the SPL design philosophy, it incorporates many features not found on standard compressors, and a unique control system makes is surprisingly easy to use. The DynaMaxx also offers a de-compression mode which may be used to counter the effects of overcompression in previously processed source material.

Why is DynaMaxx so different? Though auto attack and release functions are nothing new, in the DynaMaxx design, the time constants are automated in a very musical way. DynaMaxx optimizes all time constants in real time during processing so that the compression characteristics are continually matched to the source material.

The DynaMaxx circuitry actually uses two of the excellent THAT 2181 VCAs in SPL’s Double VCA-Drive mode configuration, which doubles the operating range while increasing transparency and reducing distortion. Another benefit of the DynaMaxx circuitry is that high compression ratios do not affect high frequency detail – high amplitude, low-end bass can be controlled without introducing pumping or other negative side-effects. Similarly, complex stereo sources can be processed easily and very musically.

The DynaMaxx has numerous applications in recording and mixing, as well as for live applications, and because of the level of intelligent processing within the unit, there are only two controls to adjust per channel, making operation very intuitive.

SPL DynaMaxx RPM RackPack Module Options

Lundahl I/O Transformers

The Input and Output 1 stages may be transformer-balanced if. Otherwise, all inputs and outputs are balanced electronically. Output 2 cannot be fitted with a transformer. It is actively decoupled and allows for the input signal to be split into two output signals.

As an option, the DynaMaxx RackPack module can be fitted with input and output transformers from Lundahl. The transformer options can only be ordered by purchase, a later upgrade is not possible.

Information On Lundahl I/O Transformers

• Transformers have a pleasant sound characteristic, especially the low end sounds rounder and more full-bodied. The top end benefits from a softer and silky atmosphere without being emphasized.
• Further advantages are aspects of improved operational safety: galvanic insulation excludes the transmission of damaging currents.
• Electromagnetic, high frequency or digital interferences have no influence on the signal quality, hum potentials are cancelled out.
• From our listening experience we can recommend Lundahl I/O transformers in any case, and their improved operational safety is an advantage that cannot be overestimated in any critical or complex studio, broadcast or sound reinforcement installation.
