E 111
E 112
Equalizer LED indicator
Allows adjustment of frequency response by using the EQ sliders , bandwidth controls and Centre
frequency controls while the LED remains lit. The frequency response is flat regardless of the position
of the EQ sliders when the LED is extinguished. Select either of the frequency modes with the equalizer
switch
Peak LED indicator
Lights when the output exceeds 6dB before a clipping level is reached. For minimum noise, adjust the
input controls so the LED can come on occasionally. When the LED still lights up even if the input level

Highpass filter switch
Attenuates the frequency component lower than 40Hz at the rate of 12dB per octave in the IN position.
Lowpass filter switch
Attenuates the frequency component higher than 12kHz at the rate of 12dB per octave when IN.
Equalizer switch
Placing the switch in the IN position causes the equalizer LED indicator to turn on, and provides the
frequency response adjusted with the EQ sliders , bandwidth controls and centre frequency
controls . With the switch in the OUT position, the equalizer LED goes out and the frequency response
is flat just as the EQ sliders allow for a flat response when set to "0".
Input level control
Adjusts the input level within range of -12dB to +12dB. Adjusting the control so the peak LED indicator
may occasionally light up reduces noise generated in the E 111 and E 112 equalizers. When the peak

EQ sliders
Provide 12dB of boost or cut at each of the 10 frequencies, which are centred at ISO 1 octave increments
from 31.5 to 16 kHz.
Bandwidth controls
Adjust a bandwidth. ("Q" is adjustable within range of 1.5 to 8.)
Centre frequency controls
Adjust the centre frequency within range of 1 octave.
