PURE ships in two hardware generations. Neither replaces the other, and the right pick depends on the DSP to be used, and the controls you need.
Gen1 and Gen2 differ in how they control volume. Gen1 adjusts volume through the DSP’s wired analog remote-control input. It therefore requires a DSP adapter matched to the processor which is included in the sale.
Gen2 requires no DSP adapter, as it performs volume attenuation internally before it delivers the digital SPDIF signal to the DSP. This broadens the range of compatible processors and frees the DSP’s remote input for accessory digital controllers like Helix's Conductor or Director, for example.
Retaining the wired remote architecture means Gen1 can also support integrated subwoofer-level control, unlike Gen2. Additionally, Gen1 is able to take advantage of DSP's with adjustable loudness contours while Gen2 cannot.
Which Generation is right for you depends on the features you prioritize:
Get Gen1 if you want subwoofer level control capability from your head unit, and/or intend to use your DSP's programmable loudness contour. Just make sure you have a compatible DSP first.
Get Gen2 if you want to be able to use DSP brands like Audison, or any other than uses digital-only remote control interfaces.
IMPORTANT NOTES:
Make sure to add the correct PURE model option above that matches your particular DSP make and model.
PURE comes with a two-foot pigtail harness. If you prefer an extended length harness, add this upgrade to your order.
