placed close to the center of the front loud-
speaker array.
Two phase matching switches in the
crossover allow compensation for incorrect
phase alignment. Four settings are provided
between 0° and -270°.
Coarse phase
correction method
Connect an audio frequency signal genera-
tor to a signal input on the subwoofer which
has a main loudspeaker connected to the
corresponding “OUT” connector. 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.
Toggle the -180°
phase switch ‘ON’
and ‘OFF’ and set
it to the position
which gives the
lowest sound level
at the listening
position.
Next toggle the
-90°phase switch
‘ON’ and ‘OFF’,
and again set it to
the position which
gives the lowest
sound level.
Finally, set the
-180°phase switch
to the opposite set-
ting.
Using the F One 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 One 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 One 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 approxi-
mately 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 One 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 One 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 approxi-
mately 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 One has an integrated protec-
tion function that automatically reduces
the playback volume to a safe level if the
subwoofer is overloaded. This function
overrides commands given with the remote
control. If this occurs frequently, reduce the
playback level until the subwooofer func-
tions normally.
Matching the remote control
to the subwoofer
When shipped, the remote controls delivered
with F One subwoofers will function with any
other F One subwoofer as well. If this is not
desirable, for instance when there are sev-
eral F One subwoofers in the same prem-
ises, and the user wishes to avoid the situ-
ation 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 pow-
ering 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 temporar-
ily switch off the subwoofer. The white 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 sec-
onds 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 One units.
