FF – 4.2 INTRODUCTION
The features and layout of the FF-4.2 were determined in collaboration with leading
loudspeaker manufacturers Funktion One.
The FF-4.2 has 4 channels; each channel has two inputs selectable by a push switch. There
is also a fifth input which is the console microphone input.
The FF4.2L has linear faders and the FF4.2R has rotary, both versions can have internal or
external power supply, external power supply versions are denoted by a suffix “P”.
Channel 1 is switchable between low impedance microphone and stereo balanced line
input. Phantom power is available for the microphones (recessed switch) and gain
adjustment (recessed). Channels 2 to 4 are switchable between a stereo line input and a
phono (RIAA) input.
Each channel has a gain control, 4 band “full kill” EQ, selectable variable frequency high
and low pass filters, 2 x AUX switches, cue switch, channel fader and 12 LED level
indication plus clip LED.
The variable frequency high pass filter is adjustable from 20Hz to 2Khz; the variable
frequency low pass filter is adjustable from 20Khz to 2Khz.
Channel 1 has a compressor selected by a switch, the compressor threshold is indicated by
an LED and the threshold and ratio may be adjusted by recessed pots in the base of the
unit. The compressor acts on both Mic and balanced line inputs.
Channel 1 MIC is on a separate MIC buss, there is a recessed switch in the base of the unit
that allows the MIC buss to be included in the booth or post booth (as the console MIC).
Channel 1 is not assignable to cross fader; channels 2 – 4 are assignable to cross fader.
The cross fader has a fader curve control located just above the cross fader.
Console MIC is upper right on the FF4.2 and includes recessed phantom
power switch and recessed gain trim. There is volume control, 3 band EQ
(+5dB to -26dB); MIC ON/OFF switch and cue switch on the front panel.
The master output is balanced stereo on XLR’s, master level is indicated on
a stereo 12 LED meter with volume control below the meter. There is an
insert (stereo jack) in the master output enabled by a push switch.
The booth output is also balanced stereo on XLR’s, the booth level is
indicated on a stereo 12 LED meter with volume control below the meter.
There is also a balance pan control and mono select switch for the booth.
The AUX 1 and AUX 2 outputs are both balanced stereo on dual jack
sockets with a level control on the front panel.
There are two headphone outputs (1/4” jack and 3.5mm jack) with volume
control and cue balance pots; there is also a split switch and pre/post EQ
switch (pre EQ is also pre high pass and low pass filter).
There is also a balanced stereo zone output with connection for remote
zone control panel (remote panel not included), the zone output may be
switched to mono via recessed switch.
There is also record output on phono sockets, switchable (recessed)
mono/sub bass balanced output and remote mute connection.
