Hi everyone,
Could do with a bit of guidance please, hope Ive got this in the correct section.
We're a Am-Dram group changing from Pc-Stage to QLC+ and want to also upgrade our old DMX-USB Adaptor.
I know the industry standard is Enttec, but was looking at "Nrpfell 512-Channel USB to DMX DMX512" as on well
known shopping sites.
Any opinions on the Nrpfell? Looks like it supports older Os versions, so is it's tech a bit old now also? Just going
on price really, but would be nice to future proof by having input & output. What controllers do you guys use?
And should we stick with USB or go Artnet?
Hope someone can help.
Which USB Controller

Please only use a fully supported adapter: https://www.qlcplus.org/features.html
The idea of stepping into Artnet ...
In the end everything will be converted to DMX (unless very complex and pricey fixtures - but you cannot daisy chain these - you need a feed to a switch for each in service)
It will make debugging way more complex (unless you have good knowledge about network topology, subnets, broadcast, routing, dual nic, etc...)
One DMX cable (universe) can hold 512 addresses and without splitter up to 32 fixtures.
non intelligent or intelligent interface
An intelligent interface has a processor aboard (among other specs like buffers etc) and takes care of the DMX timing autonomously. QLC+ just sends the instruction: channel 72, value 255.
Non intelligent interfaces depend on the processor power of the host to create a pulse train that will form a DMX message. QLC+ will instruct the driver and the processor of the host will compose the pulse train - this message is sent 1-1 on the DMX bus. If your processor is stressed out by other processes, there is a good chance that DMX timing will be off spec and the generated pulse train won't be validated correctly.
Budget wise this decision has an impact.
(And I cannot believe the Nrpfell is enabling 1024 parameters in Grand MA2 !! If so this would become very interesting
