10. CD INPUT: Use these RCA jacks to connect the line level (or headphones) output of a CD player, tape deck or rhythm machine to the amplifier. The inputs to these jacks are summed into a mono signal which is fed into the BA115HP/BA210�s power amplifier. The signal level from these jacks is adjusted by the amplifier�s Master control (#8). If the signal from the source connected to these jacks is too strong, use the output level control on the source to adjust the signal to obtain the proper level for a good mix. 11. TUNER: Use this electronic tuner to tune your instrument. A complete description of the tuner is located on page 6. 12. HEADPHONES: Use this jack to listen to the amplifier through a pair of stereo headphones. The internal speaker is disconnected when the headphones jack is used.
13. BAL. LINE OUT: This jack supplies a post-eq, balanced line level signal for connecting to a house sound board, recording unit or external amplifier. 14. POWER: Use this switch to turn the amplifier on or off. The adjacent LED will illuminate when the amplifier is turned on. 15. AC LINE CORD: (rear panel, not shown) This grounded power cord is to be plugged into a grounded power outlet, wired to current electric codes and compatible with voltage, power, and frequency requirements stated on the rear panel. Do not attempt to defeat the safety ground connection. 16. HF LEVEL CONTROL: (cabinet back, not shown): Use this control to adjust the output level of the high frequency driver. With the control fully counter clockwise, there is no output from the high frequency driver. The high frequency driver output increases as you rotate the control clockwise.
