DIGITAL PROCESSING ARENA
Delay: Highlight the third box from the left to select the "Delay" and press the "edit" knob down to ad-
just the amount of delay desired. You can select the "Lib" button to save the current adjustments to the
library or to load from the library. The delay is most often used when remote speakers are set up away
from the regular Main speakers. The number of ms of delay needed is close to the distance in feet plus
20 ms (so that a remote speaker located away from the Mains by 100 feet will need a delay of approxi-
mately 120 ms). This should normally be done in the "Dual Mono" output mode.
This delay is very useful in the "Stereo" mode for adding delay to compensate for the distance between
the backline amplifiers and the front Main speakers. It is probably best to set this in relationship to the
loudest (peak) sound coming from the backline (usually the snare drum). If the snare drum is 12 feet
from the front of the stage, start with about 12 ms of delay plus 10 - 30 ms for the Haas effect (so be-
tween 22 and 42 ms or to taste). By adjusting the backline to the FOH Main speakers, a sort of focus
will take place. The audience will hear the sound as though it is coming from the band itself and not so
much coming from the PA ... a good thing to do!
Limiter: Selecting this function sets a limiter on the L/R outputs of your FX mixer. This helps to prevent the
mixer from clipping as well as overdriving the rest of the output chain. Press "edit" to adjust the parameters
of the output limiter. The threshold should probably be adjusted to max (+10 dB) and the mode adjusted
to "soft knee" in most cases. 50 ms of Attack and 500 ms of Release time are good starting points but may
be adjusted as necessary. If you are "hearing" this limiter actually work, then you are probably driving too
hard and should back off. This limiter is not intended to be a "sonic shaper" (use the "compressor" function
in the "Effects" processors). You may "save" or "load" from the library as necessary.
Digital I/O:
The digital I/O section of the FX mixer consists of the Utility and USB functions.
UTILITY
Screen Adjustment: Turn knob to adjust the contrast of the screen. You may also choose to invert the
screen colors. Press the "save" button to keep your adjustment or "back" to ignore.
Change Security Settings: The user can lock out others from changing effect, output or digital I/O
presets by selecting the appropriate check boxes. Once a box is checked, a password will be required to
make a change to that setting.
Change Password: A password may be set by
turning the left encoder knob to select a char-
acter for each of the four placeholders. Once
you have selected the characters, press the
"enter" button and validate your choice. This
password will now be necessary for making
changes to any of the settings that have been
selected in the "Security Settings" above. This
password will also be necessary to do a factory
reset.
Restore Factory Settings: Resets all param-
eters to factory settings and will erase all user presets and passwords.
USB
The FX2 mixer console allows the user to record or play back MP3's directly to/from a thumb drive placed
in the USB A port. Note the USB B port directly streams audio in or out and is treated as a "sound card"
by the computer. How you treat this output will depend on the computer you use and the software you
are running to control it. Only one USB output may be connected at a time, and the USB B cable must
be disconnected before a device in the USB A port is accessed, and vice versa.
