A. SHELVING/ BELL SWITCH – This switch toggles between Shelving and
Bell shape. When the switch is pressed, the Bell shape is active.
B. OFF – When the FREQ . rotary switch is in the OFF position, the band is
not engaged (i.e. the filter circuit and the LEVEL control are inactive).
However, the audio signal still travels through the discrete circuit and the
audio transformers.
C. FREQ. – This rotary stepped switch determines the frequency point for
each band. The frequency points for each band are as follows:
Band 1 : OFF, 45Hz, 65Hz, 100Hz, 180Hz, 330Hz, 470Hz
Band 2: OFF, 180Hz, 220Hz, 270Hz, 330Hz, 390Hz, 470Hz, 560Hz,
680Hz, 820Hz, 1kHz, 1.3kHz
Band 3: OFF, 1.2kHz, 1.5kHz, 1.8kHz, 2.2kHz, 2.7kHz, 3.3kHz, 3.9kHz,
4.7kHz, 5.6kHz, 6.8kHz, 8.2kHz
Band 4: OFF, 3.3kHz, 4.7kHz, 6.8kHz, 10kHz, 15kHz, 23kHz
D. LEVEL – Each band has a high quality continuously variable
potentiometer that controls the amount of gain or attenuation (+/- 12dB).
E. HI-Q/ LOW-Q SWITCH – This switch controls the sharpness of the peak
or dip and it toggles between High Q and Low Q. When the switch is
pressed, the High Q is active.
F. IN – This switch toggles between the active (LED ON) and bypassed
(LED OFF) modes. Since the unit employs a bypass relay system, no
audio signal passes through this switch. Instead, the IN switch is a DC
voltage switch that controls the relays’ state.
