Quiet on headphones

(1/1)

TwistedGenetics:
Hi

My preenfm2 R6 is quiet, I really notice this when using headphones. Is this normal?

Cheers

Xavier:
Do you use the regular audio jack for your headphones ?
What PCB version do you have ?

Please read that and let me know if that helps.

Hi Xavier

Is the preenfm2 (latest board R6)

I’m using a Jack to headphone adapter see attached picture.

If I set the other 3 instruments to 0 voices this is as loud as it gets. If I set them to 3 each it gets quieter which what I would expect?

The loudest I get it is one instrument set to one voice but then it still not as loud as say my volca fm or craft synth both running off batteries.

Megalomidiac:
These are no headphone jacks on the PreenFM but line level jacks. Without amplification they will be quiet.

served:
Yes thats normal. DAC doesnt have enough power to drive headphones. Its ment only for 10k line levels. Your headphones are low resistance and are pulling down the level.
