octave filter employs a transitional Thompson - Butterworth response for the best combination of passband flatness
and time domain response. LED indicator illuminates amber when active.
7. MIC / LINE switch -
This switch selects which input feeds the EQ/COMP section - either the microphone preamplifier
input (MIC IN from the rear panel XLR or the front panel HI-Z TRS input), or the balanced XLR LINE IN on the rear
panel. The LINE IN input is after the mic preamp section and is the direct input to the EQ/COMP section. In either
scenario, the mic preamplifier is always active.
8. LOW GAIN (EQ section) -
This knob controls the amount of cut or boost applied to the selected low frequency, from
-12dB to +12dB.
9. LOW FREQ -
This knob selects the frequency of the low band EQ, from 20 Hz to 750 Hz.
10. LOW frequency EQ type switch -
This switch selects the low EQ response mode between shelving and peak .
11. MID GAIN (EQ section) -
This knob controls the amount of cut or boost applied to the selected mid frequency, from
-12dB to +12dB.
12. MID FREQ -
This knob selects the frequency of the mid band EQ, from .5kHz to 4kHz.
13. MID Q -
This knob controls width / sharpness of the mid EQ control, with a range from .5 (the widest, with the most
effect on adjacent frequencies) to 5 (the sharpest, with the least effect on adjacent frequencies).
14. HIGH GAIN
This knob controls the amount of cut or boost applied to the selected high frequency, from -12dB to
+12dB.
15. HIGH FREQ -
This knob selects the frequency of the high band EQ, from 3kHz to 20kHz.
16. HIGH frequency EQ type switch -
This switch selects the high EQ response mode between shelving and peak
17. EQ IN SWITCH -
This switch activates the EQ circuit. The LED above the switch illuminates when the EQ is active, turns
off when deactivated. This switch controls a gold contact relay.
18. EQ/COMP Peak LED -
displays peaks within 6dB of internal clipping in the line section.
19. EQ>COMP / COMP>EQ -
This switch selects the order of the EQ and Compressor circuits.
20. TRESHOLD -
This knob sets the minimum level at which the compressor circuit is activated, with a range of +15dB to
-15dB.
21. ATTACK (ms) -
This knob sets how quickly (or slowly) the compressor circuit attenuates the incoming signal.
22. RELEASE (sec) -
This knob sets how quickly (or slowly) the compressor circuit releases the attenuation of the incoming
signal.
23. RATIO -
The ratio control determines the input/output ratio for signals above the threshold level. Higher ratios result
