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.

(7) +  (8)   The LINK OUTPUT is directly connected to the inputs of the 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).

◊The POWER switch does not fully disconnect the unit from the mains. To disconnect the unit from the mains, pull out the main cable plug or appliance coupler. When installing the product, ensure the plug or appliance coupler is readily operable. Unplug the power cord completely when the unit is not used for prolonged periods of time.

(12)You can replace fuses at the FUSE SWITCH of the F1220A. Always replace fuses with the same type. Please follow the instructions given in the chapter “Specifications.”

(13)The mains connection is established using a cable with an IEC mains 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.
