Equipment Care

 Use included rubber bumpers to avoid scratches.
 Always insert cables with care, and avoid cable strain to maximize audio jack life.
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:
