3. Operation
Use the Monitor/Aux output of a mixer to route the audio signal to the F1220A.
When using the monitor mix with more loudspeakers, route the audio signal of
the first F1220A to the next speaker via the LINK output. The volume level of each
F1220A is adjusted with the respective LEVEL control.
3.1 Connecting signal sources
With an F1220A and a microphone, you are able to master small PA tasks with
minimum effort. The F1220A can also be used with equipment which include
LINE outputs, such as keyboards, playback devices (for example, CD players)
and mixers with AUX Send outputs.
Connecting a signal source
•
Turn the LEVEL control fully to the left.
•
Connect the signal source to the MIC/LINE input.
•
Turn on the F1220A.
•
Turn the LEVEL control slowly to the right until you have reached the desired
volume level. The CLIP LED helps you in this case. The LED should only light
up at signal peaks, but shouldn’t glow continuously.

Caution: risk of feedback!
◊
Don’t let the microphone’s most sensitive side (front) face the
loudspeaker. Make sure to keep sufficient distance between the
microphone and the loudspeaker when using the F1220A.

3.2 Connecting multiple F1220A speakers
If you want to use the same monitor mix on bigger stages, simply increase the
number of stage monitors. For example, connect two F1220A monitors via the
LINK output. Either a microphone or line signal can be routed to the first F1220A.
Connecting to an active loudspeaker
•
Connect the LINK output of the first loudspeaker with the LINE input of the
second loudspeaker.
3.3 Using F1220A as keyboard amplifier
Usually guitar and bass guitar players have amplifiers which allow them to be
heard when playing on stage—even when a monitor system is being used.
These amps have enough power to be used on smaller stages. However, it’s quite
a different matter for the keyboardists because they normally won’t use
instrument amplifiers.
It is possible to connect a keyboard directly to the F1220A. In case you want to
hook up two keyboards, use a submixer, such as the MicroMIX MX400, to join
both signals and then connect the mixer’s output to the LINE input of the F1220A.
Route the Aux/Monitor signal coming from the main mixer to the submixer so
that you can hear your band members as well (see fig. 3.1).
3.4 Notch filter
A notch filter cancels a narrow frequency band of the signal being used.
Typical interferences, such as feedback and rumble, are found close to the
signal and are therefore easily filtered out.
To pinpoint the interfering frequency, activate the filter and slowly turn the
FREQUENCY control from the left to the right.

We recommend using our proven FEEDBACK DESTROYER PRO FBQ2496
feedback suppressor for signals with line level should continuous
feedback problems occur. For line- or microphone-level signals,
we recommend our SHARK DSP110 signal processor.
