12: Volume control - Used to set the level of the signal in connected earbuds. 13: Battery LED - This LED lights red when battery level is low and the battery needs to be replaced. 14: Balance control - Adjusts the relative levels of the two signals arriving at the EarAmp stereo input (see #2 on page 4). When set at the center 12 o�clock position, both signals are presented to connected earbuds at equal strength. When the EarAmp� is operating in �Stereo� mode (that is, when the 2 CH/Stereo switch [see #6 on page 5] is set to �Stereo,�) turning the balance control clockwise increases the relative amount of right channel signal (that is, the signal in your right ear) and turning it counterclockwise increases the relative amount of left channel signal (that is, the signal in your left ear). When the EarAmp� is operating in �2 CH� mode (that is, when the 2 CH/Stereo switch [see #6 on page 5] is set to �2 CH,�) both channels are internally mixed to mono and routed to both earbuds. In 2 CH mode, turning the balance control clockwise increases the relative amount of right channel signal (though it will be heard in both ears) and turning it counterclockwise increases the relative amount of left channel signal (again, heard in both ears). 15: Belt clip - Use this to clip the EarAmp� to your belt for convenient operation.
