7. G: DIRECT EQ (OFF or ON): This turns on a stereo 3-band EQ
section on the DIRECT OUTs. Remember, this EQ curve will then
be present on all presets, and is usefull for making basic
corrections to speakers and rooms.
8. G: DIR BASS (-15 to +15 dB): Consult the MASTER EQ function
for a detailed explaination of these 7 eq parameters.
9. G: DIR BASS (20 to 135 Hz):
10. G: DIR MID (-15 to +15 dB):
11. G: DIR MID (31 to 6000 Hz):
12. G: DIR MID (0.1 to 2.5 OCT):
13. G: DIR TREBLE (-15 to +15 dB):
14. G: DIR TREBLE (2000 to 12.0k Hz):
15. G: STAGE EQ (OFF or ON): This turns on a stereo 3-band EQ
section on the STAGE OUTs. Remember, this EQ curve will then
be present on all presets, and is usefull for making basic
corrections to speakers and rooms.
16. G: STAGE BASS (-15 to +15 dB): Consult the POST EQ function
for a detailed explaination of these 7 eq parameters.
17. G: STAGE BASS (20 to 135 Hz):
18. G: STAGE MID (-15 to +15 dB):
19. G: STAGE MID (31 to 6000 Hz):
20. G: STAGE MID (0.1 to 2.5 OCT):
21. G: STAGE TREB (-15 to +15 dB):
22. G: STAGE TREB (2000 to 12.0k Hz):
23. G: VOLUME PEDAL (OFF or ON): This would normally be set to
ON, so that when you plug in an expression pedal to the VOL
PEDAL jack, the pedal will become active. However, if the circuitry
involved in reading the expression pedal were to fail, the volume
could be stuck to maximum attenuation, and since Volume is a
hidden parameter that can’t be adjusted, this parameter allows you
to turn OFF the VOLUME PEDAL, which sets the volume to full on,
allowing the unit to still be usable. It is recommended to use a
volume pedal with an audio taper pot, the resistance of which is not
critical, since the circuit is just reading the ratio of two voltages.
You will need a ‘Y’ cord which has a single ¼” TRS (tip-ring-sleeve)
jack at 1 end and two ¼” mono jacks at the other end, assuming
your volume pedal has separate IN and OUT jacks (sometimes
labeled INST and AMP). The ring of the VOL PEDAL jack supplies
3.3 volts DC to the IN jack on the pedal, and the tip of the VOL
PEDAL jack reads the wiper voltage on the OUT or AMP jack of the
pedal. If you connect them backwards you won’t damage anything,
but the volume change will be very abrupt from full off to full on in
the bottom part of the pedal travel. You should mark the ends of
the Y cord so that you know in the future which end connects to the
IN or INST jack on the pedal.
