General description
F Two Active Subwoofer
The Genelec F Two is a very compact
active subwoofer designed to complement
up to five Genelec G One or G Two active
loudspeakers or a pair of the slightly bigger
G Threes. Linked together two F Two’s
can also be used with G Fours. The F Two
extends the system’s bass response down
to 27 Hz and integrates perfectly with the
main loudspeakers in any environment. The
playback level for the whole system is con-
veniently controlled by the wireless volume
control provided with the subwoofer. A wired
volume control is available as an option.
The F Two has an integrated bass manage-
ment for the five main channels which directs
the frequencies below 85 Hz to the subwoofer
and higher frequencies through the output
connectors to the main loudspeakers.
Installation
Before connecting the audio signals, ensure
that all equipment is switched off.
Pull out the battery insulating strip from
the underside of the remote control as
shown in figure 1. This strip insulates the
battery from the contacts on the remote
control during shipping and the remote con-
trol does not function before it is removed.
The subwoofer is equipped with six RCA
signal inputs (L, R, C, LS, RS and LFE/LINK
IN) and two balanced XLR inputs (LEFT,
RIGHT). These allow connecting the F Two
to a variety of line level audio sources with
either unbalanced RCA or balanced XLR
type audio connectors. Suitable sources are
preamplifiers, computer sound cards, port-
able audio players, “PRE OUT” connectors
on a Home Theater receiver, etc.
The output section of the subwoofer con-
tains corresponding L, R, C, LS and RS RCA
connectors for the main loudspeakers, a
LINK OUT RCA connector for linking multiple
subwoofers together and two balanced male
XLR connectors (LEFT, RIGHT).
The L and R RCA inputs and outputs are
working in parallel with LEFT and RIGHT
XLR inputs and outputs.
As the F Two contains its own amplifier, no
separate power amplifier is needed. Never con-
nect the F Two to the loudspeaker outputs of a
power amplifier, integrated amplifier or receiver.
Connecting a stereo system
Connect the audio signal cables from your
source to the corresponding input connec-
tors. The F Two offers both balanced and
unbalanced signal routes. For stereo signals,
use either the LEFT and RIGHT XLR inputs
or the L and R RCA inputs. Next, connect
the subwoofer to the main loudspeakers with
RCA or XLR cables from the corresponding
output (OUT) connectors on the subwoofer
to the signal inputs of the main loudspeakers.
You can also connect an unbalanced
source to the RCA L and R inputs and use
the parallel LEFT and RIGHT XLR output
connectors as outputs. This provides bal-
anced signal from the subwoofer onwards,
and facilitates easy connection to main loud-
speakers with XLR inputs, such as the G
Three or G Four.
Connecting a
surround system
The F Two has an integrated crossover net-
work for the five main channels which directs
the frequencies below 85 Hz to the subwoofer
and higher frequencies through the output
connectors to the main loudspeakers. When
using a surround sound processor, select a
loudspeaker setting “Large” for the channels
routed through the subwoofer.
Connect the five main channel signal RCA
cables from the signal source to the RCA
input connectors L, R, C, LS and RS.
The LFE channel of the preamplifier or
processor can be connected to the LFE IN/
