Hi there,
yesterday, I worked with a Mackie Onyx 4880.
I think, you all know it: aprox. $5500 48 mono channels etc.
Website says:
Onyx Mic Preamps
123dB total dynamic range
-129 dBm Equivalent Input Noise
0.0007% Total Harmonic Distortion
and now the funny thing: it says for real
You can read that on: http://www.mackie.com/products/onyxseries/preamps.html
Alright, I was interested on how they did it.
So I opened the device and check the mic-channels.
I began to cry (you can ask a friend of mine).
They're using NJM2068 OPAs and cheap 2SA-Yapan transistors.
It's even theoretically impossible to reach 0,0007% THD because the NJMs have 0,001% at 100% ideal values and this is laboratory only!!
It's a big marketing-fake.
About the "-129.5 dBm Equivalent Input Noise" ... yeah, you could reach this, if you make a short circuit!! But in "real life", you can reach about -110dBm - again only if everything is 100% ideal.
I informed the consumerism / consumer protection, since it is a big fraud on customer. Something like that I've never seen a long time.
What do you think about it?? I am REALLY upset and angry!!!
Best,
Tobias
