Turn on the HA15 by depressing the front panel power switch. The power 

LED will illuminate to let you know the power supply is properly seated.

ImPoRTAnT noTe

As the HA15 is designed to work with all types of headphones 

or varying impedances. It incorporates a powerful amplifier that 

is capable of damaging your hearing if you are exposed to loud 

music for an extended period of time.  As we have no control 

over the impedance of the headphone you are using, it is your 

responsibility  to  ensure  that  listening  levels  are  kept  under 

control and that you follow the health and safety guidelines in 

your community.  We do not recommend headphones be used 

by children unless they are carefully monitored by a parent or 

guardian.  The use of ear-buds is not recommended.
