variety of headphones. The high-current output design allows it to easily drive
headphones with a wide impedance range and the line and preamp outputs
allow you to connect to an external amplifier or a set of powered speakers.
To prevent damage to your hearing, do not listen to music at excessive
volume levels. Turn down the volume before connecting headphones.
Avoid prolonged use of headphones.
Keep away from water or moisture of any kind. Do not use in dusty
Do not open or attempt to repair this amplifier. Always use the included AC
power adapter or an exact replacement.
If you cannot hear sound, check the following:
Double check all connections to ensure that they secure.
Double check the source and destination routing.
