Tapco MIX.220FX Owner's Manual - Internal Effects

INTERNAL EFFECTS
The internal effects circuit receives a mono signal
from the FX bus, and it outputs a stereo signal onto
the main mix buses.
The input signal is controlled by the MASTER
FX AUX SEND knob [27] and the FX INPUT LEVEL
knob [35], while the outputs are controlled by the FX
RETURN [31] knob.
Inside the processor, the analog audio is
converted to digital, this is processed by the internal
DSP effects processor, and the result converted into
a stereo analog signal.
33. Internal Effects Select Knob
The internal effects processor has 16 great
preset effects to enhance your sound, confuse
cats, and upset hamsters, if that is your idea of
fun. Each has been carefully modeled to represent
standard effects. Note that the effects output mutes
momentarily when changing effects.
34. VARIATIONS
As you rotate this control from position 1
through 16, the “strength” of the effect increases.
For example, if using a reverb effect, a low number
produces a short reverb time, and a larger number
produces a longer reverb time.
35. FX INPUT LEVEL
This knob allows you to adjust the signal level
going into the internal effects processor. As a general
rule, adjust the FX INPUT LEVEL knob until you just
barely see the FX OL LED [36] blink. This will give
you the best signal-to-noise ratio for the effects
signal.
36. FX OL
This LED indicates when you are approaching the
clipping point for the digital effects processor. If you
see the FX OL overload light blinking frequently, turn
down the FX INPUT LEVEL knob until it just turns off
during the louder passages, riffs, chords, yells, etc.
37. FX MUTE
Press this switch in to mute the internal effects
processor, and so prevent its output from appearing
on the main mix or stage monitors. The LED next
to the FX MUTE switch reminds you whenever the
processor is muted.
Use FX MUTE if you are not using the internal
effects, or use it to quickly compare between the
effective effect of effects and the effect of no effects.

38. ALT 3-4 Master Faders (Mix.0FX)
These faders control the level of the signals sent
to the ALT 3-4 OUTS [53]. Remember, channels are
routed to the ALT 3-4 OUTS when their MUTE/ALT
3-4 switch is pushed in (Mix.220FX only).
39. SUB 1- Master Faders (Mix.60FX)
These faders control the level of the signals sent to
the SUB OUTS [54]. All channels that have their Sub
1-2 assign switch [17] pushed in appear at the SUB
OUTS (Mix.260FX only).
The ALT 3-4 and SUB 1-2 signal is off
when the faders are fully down, the
“U” marking is unity gain, and fully up
provides 10 dB of additional gain. If
you are using the two ALTS or SUBS
as a stereo pair, make sure that both
faders “ride” together to maintain the
left/right balance.
40. SUB ASSIGN TO MAIN MIX
Switches (Mix.60FX only)
One popular use of the subgroups
is to use them as master faders for a
group of channels on their way to the
MAIN MIX. Let’s say you’ve got a drum
kit using several channels and you’re
going to want to adjust the overall
volume of just the drums with two
master faders. Just un-assign these
channels from the MAIN MIX, reassign
them to subgroups 1-2, engage the
SUB ASSIGN TO MAIN MIX LEFT on
subgroup 1 and SUB ASSIGN TO MAIN
