DIGITAL EFFECT ENGINE
The following refers to Impact X models only.
32. Digital Effect Display
This 2-digital numeric display shows the program num-
ber that is currently applied to your EFX audio signal.
When you rotate the Program control, you can scroll
through different program numbers; however the dis-
play will revert back to the original program if a new
program is not selected within a few seconds. For a list
of available effects, please observe the Digital Effect
Table.
33. Sig and Clip Indicators
Located within the Digital Effect Display are Clip and
Sig LEDs. The Sig LED will light up when any signal
is received by the effect processor, and the Clip LED
will light up shortly before excessive signals are dy-
namically clipped. If the Clip LED lights up too often, it
may be advisable to turn down one or all EFX controls
on input channels to ensure the signal level is not too
high.
34. Program Control
This control is used to scroll through the various ef-
fects. Turning the control clockwise will allow users
to ascend into higher program numbers, and turning
it counter-clockwise will allow users to descend into
lower program numbers. Pushing this control will ap-
ply the new effect. When a tap-delay effect is selected,
pressing this control will allow users to select the tap-
delay time.
By pushing the button several times, the effect proces-
sor interprets the time between last two pushes and
remembers this as the delay time, until the button is
pushed again (this is kept, even after the power is
turned off). When the tap delay effect is selected, a
small LED will flash within the digital effect display win
-
dow at the selected intervals.
35. To Aux 1 and 2 Controls
These controls allow users to adjust the signal level
that is being sent from the Effects Engine to the auxil-
iary 1 and 2 mixing buses, the signal of which is suit-
able for connecting stage monitors, allowing artists or
engineers to listen to the music that is being played.
36. Mute Button
This button mutes the EFX channel, effectively stop-
ping the signal processed by the built-in Effects Engine
from being sent to the Main L/R mixing bus.
37. PFL Button
The PFL – or Pre-Fader Listen – button is pushed to
allow the signal of the Effects Engine to be sent to the
CTRL RM / PHONES mix. This allows easier tracking
of audio by sound engineers.
38. DSP Effects Fader
This 60mm fader will alter the signal level that is sent
from the Effects Engine to the Main L/R mix.
