Monitor – hearing noise and adjust

If you heard the noise floor when you turn the volume up while using the AR1.
It is because the noise floor was lifted when you turn up the volume, this will not affect your recording or playing on the amp/speaker. Suggest solution is to turn down the headphone volume.
If the noise still appears after turning down the volume, please contact for more assistance.
