The LOCi compensation and filter circuits are 

based upon a unique shunt topology. This 

topology is unlike conventional "state variable" 

filters in that only one signal path amplifier is 

employed. Compare this with conventional filter 

designs employing upwards of four to seven 

signal path amplifiers. Fewer amplifiers means 

greatly improved sonic integrity.  

 

LF filter points are preset to 20, 35, 60, 100, 

180, and 260 Hertz. High frequency filter points 

are preset to 1, 2, 3, 5, 8, and 12 kHz.  

 

(8) PEAK/SHELF SELECT SWITCH 

Pushbutton switch which selects LF and HF filter 

curve shape. When switch is depressed and LED 

is illuminated, EQ is shelving at 6 dB per octave. 

When switch is not depressed, EQ is peaking 

with a fixed "Q" of 1.0 about the center 

frequency selected. 

 

(9) BOOST/CUT CONTROL 

Four conductive plastic rotary potentiometers 

offering up to +10 dB of boost and -10 dB of 

cut. Boost/Cut potentiometer has 21 detented 

positions for accurate repeatability and session 

logging. 

 

(10) PRE EQ OUTPUT TRIM 

Variable output from the input to the filter and 

compensation circuits. A setting of '0' is unity 

gain. This is post preamp/switching circuits, pre 

compensation/filter circuits. 

 

(11) POST EQ OUTPUT TRIM 

Variable balanced output post 

compensation/filter circuits. A setting of '0' is 

unity gain. 

 

(12) POWER SWITCH "POWER" 

Rocker switch for switching AC line power on 

and off.
