How to use the Notch Filter
First plug your guitar into an amp or PA through the Venue D.I. and turn the volume
up to the point where it begins to feed back or where a particular note rings out
louder than the others. Then, allow the guitar to feedback a little as you slowly turn
the notch knob from left to right. When the knob reaches the position of the problem
frequency the feedback will suddenly stop.
G. Clip Meter
The Clip meter gives you a visual tool to help set the appropriate amount of gain for
your instrument. The ideal headroom is achieved when the yellow LED is lit consistently
and the red LED blinks occasionally while playing at your loudest level.
H. Gain
This feature is one of the most important keys to achieving optimum sound quality
and signal-to-noise ratio. Too little gain will adversely effect your tone and could
create additional noise. Too much gain will overdrive the input of the preamp causing
distortion. Use the clip meter to set the appropriate gain.
How to Determine the Ideal Gain Setting
Begin with the gain knob on the Venue D.I. in the counter-clockwise position. Turn
the knob clockwise as you strum the guitar until the red LED at the top of the clip
meter barely begins to flash at the loudest playing level. If the red LED comes on
strong continuously while you play, you will most likely hear some distortion coming
from the guitar signal. The meter is located in the signal path just after the EQ and
just before the FX loop. You will need to reset your gain for the optimum level if you
change the EQ settings.
