I have a Technics SL1210 turntable, Nagaoka MP-110 and a Pioneer DJM 400 mixer/amp, focusrite scarlett soundcard

When recording a vinyl I noticed something odd in the spectrograph (Spek) which I use to ensure the recording is truly 96kHz shows that the signal from the DJM400 seems to peak at 38kHz

I pulled out a rip I had done months earlier using the same setup but instead of the DJM400 I had a numark DJ mixer.

Same track:
Numark


Pioneer DJM400:


Direct from SL1210 into Focusrite (RIAA curve applied in audacity and amplified 38db):



To me it seems the pioneer phono stage is so bad it is not hitting the signal that I was getting with the numark mixer.

I was going to buy this to temp solve the issue until I can buy a new mixer that I can trust:

Just been pointed out to me the Pioneer has a 'hum' which shows on the spectrograph at 33kHz. I cannot find out where this is coming from and I have not noticed this in any recordings.

I do remove noise and so on (but not on TEST wavs) so maybe thats why ive never seen it before on pioneer rips.

Either way I am thinking I should just get a better mixer with better phono connections.

Cany anyone recommend any other than Allan & Heath?




Of course the other arguement is does any of it matter anyway as human ear cant hear anything above 20kHz




my logic was always well I can see "audio" why not capture it?
