EFFECTS PROCESSOR
Effects Type Selection LED.
8 Green LED’s show one of 16 effects types available. If the Bank LED is off the
green LED’s will show one of 1 to 8 on the effects list (or off if no LED’s are
lit), if the Bank LED is on the green LED’s will show which of effects types 9 to
16 is selected. For effects types 1 to 5, the green LED will blink in time with
the tempo of the delay time.
The green LED’s also display the level of the parameter adjustment when the
TAP button is held down. The more LED’s that illuminate, the more the pa-
rameter is increased in value or intensity.
Bank LED.
The Bank LED illuminates when one of the effects type 9 to 16 is selected. If
the Bank LED is on, then the green LED will show which effect is selected from
the list.
SEL Buttons.
The SEL buttons select the type of effect. They also adjust the parameter of the selected
effect when the TAP button is held down.
TAP Button.
The TAP button is used in two ways. If one of effects types 1 to 5 are selected then the
TAP button can be used for adjusting the frequency or tempo of the delay parameter.
If the TAP button is held down, the SEL buttons then become parameter adjust buttons to
increase or decrease the level of the parameter assigned to the selected effect.
AUX 1 & 2 Send controls.
These controls send the effects processor output signal (and the external effects return on
ST4) to the Aux buses 1 & 2, either in mono or stereo depending on the under-panel se-
lector switch (described on Page17).
These send controls are commonly used to add some reverb or effect onto the Aux 1 & 2
buses that may be used for stage monitoring or foldback.
The overall level from these send controls will be affected by the fader and the Mute
switch, so the effect can be quickly cut from the monitors if required (for announcements
etc).
Balance control.
The Balance control varies the relative levels between the left and right channels.
Mute Switch
Mutes the effect signals to the main L R and the Aux buses. The Footswitch jack socket
can also be used to mute the effects signal.
PFL Switch & PK! LED
The Pre-Fade Listen switch takes a mono sum of the stereo effects signals from before the
fader and mute switch. When pressed the signal will appear on the L R meters and be fed
to the headphones circuit for monitoring.
The PK! LED illuminates dimly to indicate the PFL switch is pressed, and brightly to indi-
cate the effects signal is within 5dB of clipping
Fader
The 100mm fader affects the level of the effects signal to the left & right buses and Auxes
1 & 2. There is 10dB of gain at the top and the unity gain position is marked by “0”.
