How can I control the volume when streaming audio via BT/AUX on my Rumble digital amp?

1. Press the “MENU” button
2. Scroll “Encoder knob” to “BLUETOOTH”and press encoder
3. Scroll “Encoder knob” to “BT &  AUX VOLUME” setting and press encoder

Here you should see four settings:

a)HIGH

b)NORMAL

c)LOW

d)MASTER

When you select MASTER, The MASTER knob on the amp will control the volume of the streaming audio heard through the amp. Be advised that the MASTER knob also controls the volume of your guitar and you will need to balance the volume using the amp volume knob and/or the streaming device volume control.

The other three options are fixed levels and balancing the volume will have to be done from your streaming device. With the scroll wheel select either “HIGH”, “NORMAL” or “LOW” and then adjust the volume on your device to a desirable level.
