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: Pro-Ject Phono Box MM Amplifier - Black: Amazon.co.uk: Electronics the-sixth 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 :nervous: my logic was always well I can see "audio" why not capture it?
