Hello,
I've acquired new amps for my rig and would like some help setting up limiters. Amps/cabs are as follows: 2 x PKN XE-6000 (3650@4ohm, 1.7Vrms sensitivity) 1 x PKN XE-2500 (1300@4ohm, 1.4Vrms sensitivity) 2 x Void Stasys 218 (2400w) 2 x Void Stasys Phil (1600w, 100w) LMS is Ultradrive. Skipping the LMS for a second, I've come up with the following figures: STASYS 218: STASYS PHIL LF: STASYS PHIL HF: Do the "Max Voltage" figures look good and should those be the ones I plumb into the PKNs for limiting? Can anyone help with limiter settings to use within the Ultradrive? Input will be digital straight from DJM900nxs. Cheers! Edited by freddymendez - 24 November 2016 at 12:14pm |

message U Victor on here, he seems to know everything about PKN, I'm sure he would help you out.

to be fair i have read a lot about PKN and seen UViktor all over those
posts, I think a lot of what he says may appear to be bashing but is
likely due to translation.
i have an interest in PFC since mainly I will run from generators and want to squeeze as much power from them as possible. it's no secret that those Inukes, sae, non PFC style amps can suck up big current whilst only being able to make use of a small portion of it. that's what i'd like to avoid. i've heard various SAE myself, I've spoken to the authorised warranty repairer in the UK, and if i;m quite honest if they had PFC then i'd have a rack of them :) |

I'd just use the limiters on your DSP frankly, the amp limiter shrinks the actual output no? Headroom is what you want.

Yes voltage is correct but its rms voltage, i think the pkn lmiters are set at peak voltage so x by 1.414 to get peak voltage.
I think some of the the new SAEs are power factor corrected, not the 4 channels though.

Personally, I wouldnt bother setting the limiter on the PKN's for the subs.
Power rating on those is 2400W AES/RMS Program power would be 4800W, and I find the program power a more relevant figure for setting amp limiters. This does depend on the crest factor of the material you are playing of course, but for 'typical' music, you will want all 3650W the PKN can deliver. I use the XD6000 to run a 2x18" sub, loaded with a pair of 18TBX100s, which would also be 2400W - I run the XD6000 at full steam, and just use the limiter on the DSP to keep the amps out of peak. Dont forget also that PKN use the 8:32 EIAJ power rating (same as most other people) - which although a 'real' power rating it tends to give a higher short term power output figure than from an equivalent 'old school' amplifier. This means it's great for handling dynamics with peaks of 3650W handled effortlessly and cleanly, but you wont get 3650W continuously. Edited by Andy Kos - 24 November 2016 at 8:19pm |

Thanks, I'll keep the limiter off for the 218s, And I'll use Timebombs suggestion to set limiters for the Phils LF & HF. Previous bass amp was infinite 8 which although good will also suffer from poor power factor (and thus can only use a smaller amount of the already limited power that is available) - I was aware that the 3650w rating would not be continuous, so I used Lewis' calculation from amp meet three: http://www.abeltronics.co.uk/amptesting/amp-meet-three.php Which should mean that continuous output (2700w as per that test) should be over and above that of the inf 8? Thanks for help |
