er clockwise reduces the low frequency output, rotating the control clockwise increases it.
4. LO MID: Use this control to adjust the lower midrange frequency output level. Rotating the
control counter clockwise reduces the lower midrange frequency output, rotating the control
clockwise increases it.
5. HI MID: Use this control to adjust the upper midrange frequency output level. Rotating the
control counter clockwise reduces the upper midrange frequency output, rotating the control
clockwise increases it.
6. HIGH: Use this control to adjust the high frequency output level. Rotating the control count-
er clockwise reduces the high frequency output, rotating the control clockwise increases it.
7. CD INPUT: Use these RCA jacks to connect the output from a CD player or tape deck to
