Using the F Two subwoofer
When the subwoofer is powered up or after
being disconnected from the mains supply,
the power indicator LED blinks and the
subwoofer stays muted for approximately
seven seconds. This is normal and after this
the LED lights up and playback begins.
The delay allows matching the remote
control to a specific subwoofer unit (see
chapter “Matching the remote control to the
subwoofer” below). This is only necessary
when there are several F Two subwoofers
within the range of the remote control (in
adjacent rooms, for instance) and the user
wishes to avoid the situation that more than
one subwoofer reacts to the commands
given by the remote control.
The playback volume can be adjusted with
the “+“ and “-“ buttons on the remote control
(see Figure 3). The LED on the subwoofer
connector panel blinks while the adjustment
is being done and stops blinking when the
minimum or maximum level of the adjustment
range is reached.
The F Two can be muted by a short push
on the POWER/STANDBY button. A new short
push on the POWER/STANDBY button or the +
button resumes playback. The power indicator
LED blinks approximately once per second to
indicate that the subwoofer is in “mute” mode.
Pushing the “-“ button while the subwoofer is
muted reduces the volume setting.
Switch the F Two to stand-by mode by
pushing and holding the POWER/STANDBY
button down until the power indicator LED
switches off. Respectively, the subwoofer
powers up again with a push on the POWER/
STANDBY button.
The F Two is equipped with an automatic
signal sensing function that switches the
subwoofer to stand-by mode if no signal is
present in the audio input for approximately
one hour. The subwoofer resumes playback
automatically when it detects an audio signal
being fed into any of the input connectors.
Alternatively, the subwoofer can be activated
by pushing any button on the remote control.
Automatic protection function
The F Two has an integrated protection func-
tion that automatically reduces the playback
volume to a safe level if the subwoofer is
overloaded. This function overrides com-
mands given with the remote control. If this
occurs frequently, reduce the playback level
until the subwoofer starts to function normally.
Matching the remote control
to the subwoofer
When shipped, 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 subwoofers 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. This can be done during the seven
second delay in powering up that follows after
connecting the subwoofer to the mains supply.
1. Disconnect the power supply from the
mains connector for a moment and recon-
nect it or use the power switch to temporarily
switch off the subwoofer. The power indicator
LED will start blinking indicating the seven
second delay.
2. During the delay, first 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 power indicator LED on the subwoofer
stops blinking. This indicates that matching
is completed.
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.
Using multiple subwoofers
The Genelec F Two subwoofer is equipped
with a LINK OUT connector to provide an
easy way of coupling two or more subwoof-
ers together in high SPL applications, for
instance when using the subwoofers with
Genelec G Four active loudspeakers. Con-
nected as described below, the “master”
subwoofer controls the volume of all sub-
woofers linked to it through this connector.
Connect an RCA cable from the LINK OUT
connector of the “master” subwoofer to which
the main loudspeaker channels are con-
nected, to the LFE / LINK IN connector of the
other, “slave” subwoofer and turn the LINK IN
dip switch on the “slave” subwoofer to “ON”.
In the LINK IN mode, the subwoofer level is
automatically set to maximum and the “slave”
subwoofer does not react to volume control
commands given with a remote control. It
only follows the volume adjustment 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 sub-
woofers give an SPL increase of 9.5 dB and
four subwoofers 12 dB compared to a single
subwoofer.
The rotary “SUBWOOFER LEVEL” adjust-
ment knob should be turned counter-clock-
wise to the next line mark on its scale. Phase
and Bass Roll-Off adjustments should be
done individually for each subwoofer in the
