Each channel features independent high and
low output level controls and a crossover
frequency rotary control, which covers a wide
range (250hz to 6khz). All three outputs have
a 30 cycle low cut switch to eliminate low-end
rumble. The subwoofer features an independe n t
o u t p u t level & rotary control for frequencies in
the 50hz to 250hz range.
