1. INPUT LEVEL CONTROL
Sets the incoming signal level to avoid clipping. If the “PK” LED
illuminates, lower the INPUT level.
8. LINK 1+2 SWITCH
This switch allows BOTH effect channels of the FX2 to process the INPUT 1
signal and combine BOTH effects at OUTPUT 1. When the LINK 1+2 button
is “IN”, the EFFECT 2 MIX control will also adjust the level of EFFECT 2
heard at the EFFECT 1 OUTPUT.
2. PEAK LED
The “PK” LED displays when the processor is being overloaded by too
much input signal. The LED should stop flashing when the INPUT level
control is reduced to prevent distortion.
9. LINK LED
Lights when the LINK 1+2 function is active.
3. MIX CONTROL
Adjust the MIX control for the amount of effect desired. “0” will have no
effects present. Gradually rotating the control towards 10 increases the
amount of effect while decreasing the direct signal level. When the LINK
1+2 button is “IN”, the EFFECT 2 MIX control adjusts the level of EFFECT 2
heard at both EFFECT 1 and EFFECT 2 OUTPUTs.
4. OUTPUT LEVEL CONTROL
Adjusts the overall output volume of the unit.
5. EFFECT
The EFFECT control selects which effect will be used and adjusts the
following parameters for the related effect:
(ECHO) REGENERATION - the number of times the echo is repeated.
(REVERB) DAMPING - How much high frequency ambience is present in
the reverb.
(CHORUS) REVERB LEVEL - Amount of background reverb present.
(FLANGE) SPEED - The speed of the flange “swelling”.
6. PARAMETER
The PARAMETER control adjusts the following parameters for the related
effect:
(ECHO) TIME - The delay time between repeats from 50ms to 500ms.
(REVERB) DECAY - How long it takes for the reverb to die out after the
original signal stops.
(CHORUS) DEPTH - How intense, or “thick” the chorus effect is.
(FLANGE) DEPTH - How intense, or “thick” the flange effect is.
7. MUTE
The MUTE switch will turn off the effects heard at the output. The direct
signal remains intact. (level determined by the MIX control) The LED
illuminates when the effects are muted.
10. POWER
Push this switch to the UP position to apply power to the unit. The
POWER LED will light to show the FX2 is on.
REAR PANEL
11. LINE CORD:
The exclusive built-in auto switching power supply allows you to connect
any voltage from 90 to 255v 50-60Hz. Use a 3-conductor line cord for
maximum safety. If the FX2 is to be plugged into a 2-prong outlet, use a
quality 3-to-2 prong grounded adapter. Do not defeat the grounding pin of
your AC line cord.
12. GROUND LIFT SWITCH:
This switch lifts the grounds on the inputs and outputs when depressed.
This is useful for getting rid of ground loops.
13. 1/4" INPUTS (EFFECT 1 AND 2):
This input will accept input signals from mixer sends, amplifier effects
sends, etc. The “tip” is the signal, the “sleeve” is the ground (shield).
When in LINK 1+2 mode, the EFFECT1 signal will be processed by both
EFFECT 1 and EFFECT 2.
14. FOOT SWITCH JACK:
Using a footswitch such as the Carvin FS-22 will allow you to mute
EFFECT 1 or EFFECT 2 remotely. The “tip” on the plug mutes EFFECT 1,
the “ring” mutes EFFECT 2, and the “sleeve” is the ground.
15. 1/4" OUTPUTS (EFFECT 1 AND 2):
This is the unbalanced output for the processor. Use this to return the
processed signal to channel inputs or effect returns on a mixer or to the
return on an amplifier effects loop. The “tip” is signal, the “sleeve” is
ground (shield). When in LINK 1+2 mode, both EFFECT 1 and EFFECT 2
will be heard at the EFFECT 1 OUTPUTS. The EFFECT 2 OUTPUT will
function normally.
FX2 Applications:
Effect Settings and Usage:
FIG. 1 shows a typical mixing board connection. This setup allows
multiple signals to be processed by a single effect channel. The FX2
INPUT is connected to a master EFFECT SEND of the mixer. The OUTPUTs
of the FX2 are connected to a master EFFECT RETURN of the mixer. The
MIX control should be turned fully clockwise to 10, or “WET” setting for
this type of setup. Complete a second hookup to the other channel of the
FX2 using a second set of SEND and RETURNS. Be sure the LINK 1+2
switch is “OUT”. Connecting the OUTPUTs of the FX2 to mixer input
channels instead of the returns of your mixer will allow even more control
over signal routing and enables you to use the mixer’s channel EQ to
enhance the sound of the effects.
The FX2 is capable of many effect variations. Start with the controls at
moderate settings and tailor your sound from there.
REVERB is the most common effect. Reverb can add both presence and
depth to a performance. A reverb with a short DECAY can make vocals
and instruments sound more dense and “alive”. Longer decay times have
a more dramatic effect and are best used in sparse musical atmospheres.
Too much reverb, especially with long decay times, can cause your sound
to be “washed out”.
ECHO is a combination of a DELAY and some REVERB. The ECHO
setting gives the impression of multiple “copies” of your sound reflecting
off a far away object. The TIME setting adjusts how far apart the “copies”
are and REGENERATION adjust how many “copies” are made.
CHORUS can have the effect of multiple instruments playing in unison.
Use the CHORUS to thicken your sound. Varying the setting of the
PARAMETER control will compliment different instruments in different
ways. The maximum setting won’t always sound best.
FLANGE gives a “swirling” or “tubular” sound and is great for making
musical parts stand out from the rest of a song. Deep, howling type
sounds often heard from an electric guitar are sometimes created with a
FLANGER. To get this type of sound, set the EFFECT control to the “F” in
FLANGE and set the PARAMETER control fully clockwise.
Connecting the OUTPUTs of the FX2 to INPUT CHANNELS of your mixer
enables you to use the mixer’s channel EQ to enhance the sound of the
effects and will allow even more control over signal routing. For full stereo
imaging, remember to PAN the stereo outputs to LEFT and RIGHT
respectively. If you use mixer channels as returns, leave the CHANNEL
SEND controls to the FX2 at “0” or feedback will occur.
FIG. 2 shows a typical guitar amp connection. Pushing IN the LINK 1+2
button will allow both EFFECT 1 and EFFECT 2 to be used simultaneously
in the same loop. The FX2 EFFECT 1 INPUT is connected to the effect loop
SEND of the amp. The FX2 EFFECT 1 OUTPUT is connected to the effect
loop RETURN. Dial in the amount of effect desired with the MIX controls
for EFFECT 1 and EFFECT 2. The FS-22 can be used to remotely choose
any combination of EFFECT 1 and EFFECT 2 by muting one effect at a time
or both effects.
