Troubleshooting
If the sound is distorted: Try lowering the volume control of your sound source, musical instrument, or microphone. Also, try
to reduce the overall volume of Block Rocker Max using the Master Volume knob.
If there is too much bass: Try adjusting the tone or EQ control on your sound source to lower the bass level. This will allow
you to play the music louder before clipping (distortion) occurs. You can also control EQ using the free ION Block Rocker app
for iOS and Android.
If there is a high-pitched whistling noise when using microphones: This is probably feedback. Point the microphone away
from the speaker.
If there is poor AM reception: To adjust AM reception, move entire unit.
If you can't hear the microphone over the music volume: Turn down the music volume from your source.
If you can't play music from a flash drive: The USB ports are only for charging USB devices.
