Listening Tips
For maximum sound quality, use a line level source, or turn your audio player’s volume up very high
(75%+). Volume should always be controlled from the amplifier.
You should hear
no noise
from C5 with your audio player disconnected. Every amplifier is tested to
ensure proper operation. If noise is present or audio is significantly distorted at all volumes, try a
different input cable.
This amplifier can produce dangerously loud music. Be sensible and listen safely:
