Peak LED indicator
Lights when the o u t p u t exceeds 6dB before a clipping level is reached. For m i n i m u m noise, a d j u s t t h e

so the LED can come on occasionally. When t h e LED s t i l l lights up even if t h e i n p u t level

Highpass filter switch
A t t e n u a t e s the f r e q u e n c y c o m p o n e n t lower t h a n 40Hz at the r a t e of 12dB per octave in the IN position.
Lowpass filter switch
A t t e n u a t e s the f r e q u e n c y c o m p o n e n t higher t h a n 12kHz at t h e r a t e of 12dB per octave when IN.
Equalizer switch
Placing t h e switch in the IN p o s i t i o n causes the equalizer LED i n d i c a t o r
to t u r n on, and provides t h e
frequency response a d j u s t e d w i t h t h e EQ sliders ,
b a n d w i d t h controls and
c e n t r e f r e q u e n c y
controls
. With the switch in the OUT position, t h e equalizer LED goes out and t h e f r e q u e n c y response
is flat j u s t as t h e EQ sliders
allow for a f l a t response when set to "0".
Input level control
Adjusts the input level w i t h i n range of -12dB to +12dB. A d j u s t i n g the control so the peak LED i n d i c a t o r

Bandwidth controls
Adjust a bandwidth. ("Q" is a d j u s t a b l e w i t h i n range of 1.5 t o 8.)
