F Two
Operating Manual
F Two Active Subwoofer
General description
The Genelec F Two is a very compact
active subwoofer designed to comple
ment up to ve Genelec G One or G Two
active loudspeakers as a .1 / LFE channel
subwoofer in a 5.1 system 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 conveniently controlled by
the wireless volume control provided with
the subwoofer. A wired volume control is
available as an option.
The F Two has integrated bass management for the two output channels which
directs frequencies below 85 Hz to the
subwoofer and higher frequencies through
the output connectors to the main loud
speakers. When using the subwoofer
for the .1/LFE channel of a multichannel
system, we recommend that bass manage
ment is done in the processor or receiver
and only the LFE channel is connected to
the subwoofer.

Installation
Before connecting the audio signals, ensure
that all equipment is switched o.
As the F Two contains its own amplier, no
separate power amplier is needed. Never
connect the F Two to the loudspeaker out-
puts of a power amplier, integrated amplier or receiver.
Please follow the steps listed below for a
succesful setting up of the subwoofer:
1. Check the contents of the shipment.
in addition to the subwoofer, there is a
wireless remote control, a mains cable,
an IR extension cable and a Quick Setup
Guide.
2. Pull out the battery insulating strip from
the underside of the remote control as
shown in gure 1. This strip insulates the
battery from the contacts on the remote
control during shipping and the remote
control does not function before it is
removed.
3. Place the subwoofer in its position.
4. Connect audio cables from your signal
source(s). You can connect up to two
digital audio sources and two analog
audio sources.
5. Connect the main loudspeakers to
the output connectors of the subwoofer.
You can use either balanced XLR or
unbalanced RCA connectors.
6. Set the “LEVEL +10” and “-10 dB”
switches on the subwoofer and main
loudspeakers according to Table 2 on this
manual.
7. Adjust the phase of the subwoofer as
instructed in this manual and the Quick
Setup Guide.
8. Use test recordings and familiar music
pieces to judge the sound balance. Use
the “SUBWOOFER LEVEL” rotary control
and the “BASS ROLL-OFF” dip switches
to ne-tune the balance. If this fails,
consider relocating the subwoofer.
Operating Environment
The F Two subwoofer is designed for
indoor use only. The ambient temperature
should be 15-35 °C (50-95 °F) and the rela

tive humidity 20-80 %. Condensation is not
allowed. If it has been stored or transported
in a cool environment, the product must be
allowed to warm up in its packing to the
ambient temperature before connecting
mains power.
Connectors
The F Two is equipped with both analog
and digital signal input connectors, that
can be used simultaneously to connect
up to four audio sources (two analog, two
digital). Switching between sources is done
with the Select button on the connector
panel or with the “<” and “>” buttons on
the remote control. The colour of the LED
light on the subwoofer enclosure indicates
which source is selected.
Analog Input Connectors
The F Two has two stereo inputs (3.5 mm
jack and L/R RCA connectors) and an LFE/
LINK RCA connector. The stereo inputs
are parallel, so you can connect two audio
sources at the same time, just play only
one of them at a time. The Select function
does not work between these two inputs.
The LFE/LINK input is used for the LFE

outputs are high pass ltered at 85 Hz (See
chapter Bass Management). Additionally,
the LINK RCA output provides a summed
signal of both channels. Use this connector
as a signal output to the next subwoofer
when you want to connect several sub
woofers together. See chapter “Using Multiple Subwoofers” for more information.
System Volume Control Connector
This connector allows connecting the
Genelec 9310A Wired Volume Control
which is available as an accessory. When
connected, the 9310A controls the volume
of the whole system, including the main
speakers.
IR IN Connector
If the F Two is used with an infrared type
remote control (see chapter Use with IR
Remote Controls) and the desired location
of the subwoofer does not allow an unob
structed line of sight to the receiver located
next to the LED in one of subwoofer’s feet,
the IR extension cable provided with the
subwoofer can be connected here. The
receiver end of the cable is then brought
to a location where the IR remote control
reception works conveniently, for instance
close to the IR receiver of a television set
when using the subwoofer and speakers
with a TV.

HT Mode
Turn this switch to “ON” when you connect a
sound source with its own volume control to
-
the analog inputs of the F Two. In this mode
the volume control of the F Two does not
have eect on the analog signals. However,
it works with the digital inputs, so you can
use them to connect other signal sources.

is no audio signal present, turning this
The Intelligent Signal Sensing (ISS) function monitors the audio signal fed to the
subwoofer. If there is no signal for approxi
mately 45 minutes, the function switches
the subwoofer to Standby mode, reduc
ing the power consumption to less than
0.5 Watts. When the signal resumes, the
subwoofer powers up again. There is a
slight delay in the automatic powering up.
In those environments where the subwoofer
is required to be on all of the time, the ISS

function can be disabled by setting the
“ISS” switch to the “OFF” position. Then
the subwoofer is continuously powered and
can be turned o using the power button on
the remote control or connector panel.
LED Off
This switch deactivates the status indicator
LED on the “foot” of the subwoofer.
Roll-Off
These two switches attenuate the subwoofer’s bass response. At 27 Hz the
attenuation levels are -2, -4 and -6 dB (both
switches “ON”).
Phase
These two switches provide phase adjustment for the subwoofer in -90 degree increments. See chapter “Phase Alignment”.
Link
This switch selects the analog inputs and
disables input channel selection. In addi
tion, it disables the remote control and sets
the subwoofer’s level to maximum. Set this
switch to “ON”, when using the subwoofer
as a “slave” in a multiple subwoofer system.
See chapter “Using Multiple Subwoofers”.
-
Level
These two switches allow adjusting the
subwoofer’s level by -10 dB or +10 dB,
providing level matching with different
main speaker models. See Table 2 for some
examples.
Subwoofer Level
This rotary adjustment adjusts the playback level of the subwoofer. The level is
increased by turning the adjustment clock
wise and reduced by turning it counterclockwise.
-
Select
This button allows signal input selection
between the two digital inputs and the
analog input and initiation of the match
ing procedure for IR remote controls (see
Matching IR Remote Controls).
-
Power
This button switches the subwoofer
between Standby and Power mode. Note
that this button does not completely dis
connect the subwoofer from the mains
power. If this is necessary, the subwoofer’s
mains cable must be disconnected. This
button can also be used for restoring the
-
factory settings by keeping it depressed for
10 - 15 seconds. This returns the volume
setting on the remote control to factory
level and deletes possible remote control
pairing and IR remote control matching.
Also the source selection returns to auto
matic, which is the factory setting.
-
Positioning In The Room
The placement of the subwoofer in the
room aects the overall frequency response
and sound level of the system dramatically,
as at low frequencies the effects of the
room are strong. Even a slight change in
the location of the subwoofer can cause a
marked dierence in the frequency balance
and often patient and methodical experi
mentation and testing is needed to nd the
optimum placement.
The placement will also aect the bass
roll-off rate and the phase difference
between the main loudspeakers and the
subwoofer. These eects can be compensated using the controls in the subwoofer
but we recommend that at rst you leave
the switches untouched and concentrate
on nding the position where the subwoofer
gives the smoothest response, and only then
use the controls to ne-tune the balance and
phase alignment between the subwoofer
and the main loudspeakers.
Start by placing the subwoofer close to the
center of the front wall. We recommend
a distance of less than 60 cm / 24” to the
wall. This position gives increased acoustic loading and sound pressure level due to
the proximity of the front wall and oor. Ideally the subwoofer and main loudspeakers
should be positioned symmetrically and at
an equal distance from the listening position.
If the frequency balance is not quite right,
try moving the subwoofer to the left or right
along the wall so that dierent room modes
are excited at dierent levels. Positioning
the subwoofer close to a corner will boost
the bass level at lower frequencies and may
cause asymmetrical spatial imaging.
-
ISSTM Autostart
The automatic power saving function ISS
(Intelligent Signal Sensing) can be activated
by setting the “ISS” switch on the connec
tor panel to “ON.” Automatic powering
down to standby mode happens after a
certain time when playback has ended. The
power consumption in standby mode is
typically less than 0.5 watts. Playback will
automatically resume once an input signal
is detected from any source.
-
Alternatively, the subwoofer can be activated by pushing any button on the remote
control.
There is a slight delay in the automatic
powering up. If this is undesirable, the ISS
function can be disabled by setting the “ISS”
switch on the connector panel to “OFF.” In
this mode, the subwoofer is powered on and
o using the remote control or the power
button on the connector panel.
The “ISS SENSITIVITY LOW” switch
lowers the triggering sensitivity of the
ISS function. This can be necessary if the
subwoofer “wakes up” even if there is no
audio signal.
TM
Setting The Playback Level
The “LEVEL +10 dB and LEVEL -10 dB”
switches and the rotary “SUBWOOFER
LEVEL” level adjustment can be used for
matching the subwoofer’s playback level
with the main loudspeakers (See Table 2).
Fine tuning can be done with the rotary
adjustment knob.
Setting The Bass Roll-Off
Switches
The acoustic response of the subwoofer
may have to be matched to the charac
teristics of the room and the positioning in
which it will be used (see Table 1). To adjust
the subwoofer to match these character
istics use the ‘’BASS ROLL-OFF’ control
switches located on the connector panel.
When all Roll-O switches are ‘OFF’, a at
anechoic response is obtained.
Setting The Phase Control
The effect of incorrect phase alignment
between the main loudspeakers and
the subwoofer is a drop in the frequency
response of the whole system at the main
loudspeaker / subwoofer crossover fre
quency. The phase dierence between the
main loudspeakers and subwoofer at the
listening position is dependent upon the
distance from the listener to the subwoofer
in relation to the main loudspeakers. To
avoid phase differences between the
left and right main loudspeakers and
the subwoofer, the subwoofer should be
placed close to the center of the front loud
speaker array.
Two phase matching switches allow compensation for incorrect phase alignment.
Four settings are provided between 0° and
-270°.

Method
Connect an audio frequency signal generator to a signal input on the subwoofer
which has a main loudspeaker connected
to the corresponding “OUT” connector.
If the loudspeakers are placed at differ
ent distances from the listening position,
choose the loudspeaker that is nearer.
Set the generator to 85 Hz. If a signal generator is not available, it is possible to use
an audio test recording which has a test
frequency in the range 70 Hz to 100 Hz.
Suitable test signals can be downloaded at
www.genelec.com and found in some smart
phones.

Matching IR Remote
Controls
The F Two subwoofer can be used with
most IR remote controls, providing con
venient use with, for instance, the remote
control of a TV set when connected to it
via a xed level digital signal input. Turn the
subwoofer upside down so you can easily
reach the “Select” button on the subwoof
er’s connector and the status indicator LED
on the subwoofer’s foot is visible. The IR
receiver is located in the LED. Note that the
“Select” buttons on the RF remote control
provided with the subwoofer do not actu
ate the matching.
The matching procedure is as follows:
• Keep the “Select” button on the
subwoofer depressed until the status
indicator LED starts blinking red.
• Choose the button on the remote
control that you want to actuate “volume
up” function. Keep it depressed until the
LED stops blinking. With some remote
controls pressing the button multiple
times works better.
• Now the LED blinks green, indicating
that the button for “volume down” can be
selected. Follow the procedure described
above.
• Next the LED blinks blue for selection of
the button for “Select” button.
• Yellow LED indicates the selection of
“Mute” button.
• Magenta LED indicates the selection of
“Power” button.
A short press on the “Select” button allows
you to skip a step in the procedure, if you
do not want to “teach” all the commands
listed above. If you want to interrupt the
procedure, press “Select” for approxi
mately two seconds. This saves the set-
-
tings made so far. If you don’t want to
save the settings, press the Power button
for two seconds. This will also delete the
matching settings done by that point. If you
want to change the matched buttons, just
redo the matching process.
Matching The RF Remote
Control To The Subwoofer
The remote controls delivered with F Two
subwoofers will function with any other F Two
-
subwoofer as well. If this is not desirable, for
instance when there are several F Two sub
woofers in the same premises, and the user
wishes to avoid the situation that more than
one subwoofer reacts to the commands
given by each remote control, the remote
controls can be matched to operate only one
subwoofer.
-
1. Press and hold down the “Power” and
“Select “ buttons on the subwoofer until the
LED starts blinking white.
-
-
2. While the LED is blinking, rst press
and hold down the volume “+“ button on
the remote control and then the volume “-“
button. Keep both buttons pressed for a few
seconds until the status indicator LED on the
subwoofer stops blinking. This indicates that
matching is completed and the matching
operation ends automatically.
Now the subwoofer should only respond
to commands given by the matched remote
control, and respectively, the matched
remote control should not work with other
F Two units. For cancelling the matching
operation while the LED is blinking, press
and hold down the ”Power” button on the
subwoofer for two seconds. If you wish to
undo a matching completely, press and hold
down the ”Power” button on the subwoofer
for ten seconds.
NOTE: In some cases the local WiFi
network can cause problems with the RF
remote control, if they operate on the same
wavelength. We recommend the use of an IR
remote control in these cases.
Using Multiple Subwoofers
The Genelec F Two subwoofer is equipped
with an LFE/LINK output connector to pro
vide an easy way of coupling two or more
subwoofers together in high SPL applica
tions, for instance when using the subwoofers with Genelec G Four active loudspeakers. Connected as described below, the
“master” subwoofer controls the volume
of all subwoofers linked to it through this
connector.
Connect an RCA cable from the LINK connector of the “master” subwoofer to which
the main loudspeakers are connected, to the
LFE / LINK connector of the other, “slave”
subwoofer and turn the LINK dip switch on
the “slave” subwoofer to “ON”.
In the LINK mode, the subwoofer volume
is automatically set to maximum and the
“slave” subwoofer only reacts to the power
on/off commands given with a remote
control. It follows the volume adjustment
and source channel selection done in the
“master” subwoofer.
When two subwoofers connected in this
way are positioned close to one another,
bass level increases by 6 dB. Three subwoofers give an SPL increase of 9.5 dB and
four subwoofers 12 dB compared to a single
subwoofer.
The rotary “SUBWOOFER LEVEL” adjustment knob should be set in the same position as that of the “master” subwoofer unless
the subwoofers are placed in very dierent
positions acoustically, for example one in
a corner and one far from corners. In such
case, it is advisable to measure the loudness
of each subwoofer separately and adjust
them individually for correct balance.
Phase and Bass Roll-O adjustments should
be done individually for each subwoofer in the
chain, especially if they are not placed close
together. To check the phase alignment for
the “master” subwoofer switch o the “slave”
subwoofer and follow the instructions given in
the previous sections.
To adjust the phase alignment of the
-
-
“slave” subwoofer, you need to switch o
the “master” subwoofer, connect a signal
cable from one of the “slave” subwoofer’s
output connectors to the corresponding
loudspeaker and switch the LINK switch to
“OFF”. This eectively changes the “slave”
to “master” mode and the phase adjustment
can be carried out. Return the connections
and LINK setting on the “slave” subwoofer
back to the “ON” setting after completing
the adjustment.
