Fig. 2.2: Equalizer
(4) The F1220A features a 3-band sound control. Each band provides a maximum
boost/cut of 15 dB. At center position the equalizer has a flat response.
The upper (EQ HIGH) and the lower band (EQ LOW) are shelving filters that
boost and cut all frequencies above and below the crossover frequency.
The crossover frequencies of the upper and lower bands are at 12 kHz
and 80 Hz, respectively. The mid band (EQ MID) is a peak filter the center
frequency of which is at 2.5 kHz.

F1220A and carries the input signal with no processing applied. In this way,
you can route the signal to the input of another device (for example,
a second F1220A).

or appliance coupler is readily operable. Unplug the power cord
completely when the unit is not used for prolonged periods of time.

fuses with the same type. Please follow the instructions given in the
chapter “Specifications.”

connector. This cable is delivered with the F1220A. To avoid ground-loop
hum, loudspeakers and mixing consoles should be connected to the same
power circuit.
