F One Active Subwoofer
General description
The Genelec F One is a very compact
active subwoofer designed to complement
Genelec G One or G Two active loudspeakers. The F One extends the system’s bass
response down to 35 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 One 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 loudspeakers. When using the subwoofer for the
.1/LFE channel of a multichannel system, we
recommend that bass management 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 off.
As the F One contains its own amplifier, no
separate power amplifier is needed. Never
connect the F One to the loudspeaker outputs of a power amplifier, integrated amplifier 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 figure 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.
6. Adjust the phase of the subwoofer as
instructed in this manual and the Quick
Setup Guide.
7. 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 fine-tune the balance. If this fails,
consider relocating the subwoofer.
Operating Environment
The F One subwoofer is designed for
indoor use only. The ambient temperature
should be 15-35 °C (50-95 °F) and the relative 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 One is equipped with both analog
and digital signal input connectors, that
can be used simultaneously to connect
Figure 1. Removing the battery insulating strip
from the remote control
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 One has two stereo inputs (3.5 mm
jack and L/R RCA connectors) and an LFE
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
input is used for the LFE (.1) signal in a
2.1 or 5.1 channel sound system. The LFE
input has a 120 Hz low pass filter, so it is
not suitable for full frequency range signals.
Digital Input Connectors
The F One has two digital signal input connectors, one coaxial and one optical, that
accept stereo PCM format digital signal. You
can connect two digital sources and switch
between them using the Select function.

nformation.
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 One 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 unobstructed 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.
If the Intelligent Signal Sensing (ISS) function switches the subwoofer on when there
is no audio signal present, turning this
switch to “ON” reduces the triggering sensitivity of the function.
ISS
The Intelligent Signal Sensing (ISS) function monitors the audio signal fed to the
subwoofer. If there is no signal for approximately 45 minutes, the function switches
the subwoofer to Standby mode, reducing 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 off 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 below 35 Hz.
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”.
Subwoofer Level
This rotary adjustment adjusts the playback level of the subwoofer. The level is
increased by turning the adjustment clockwise 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 matching 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 disconnect 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 automatic, which is the factory setting.
Positioning In The Room
The placement of the subwoofer in the
room affects 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 difference in the frequency balance
and often patient and methodical experimentation and testing is needed to find the
optimum placement.
The placement will also affect the bass
roll-off rate and the phase difference
between the main loudspeakers and the
subwoofer. These effects can be compensated using the controls in the subwoofer
but we recommend that at first you leave
the switches untouched and concentrate
on finding the position where the subwoofer
gives the smoothest response, and only then
use the controls to fine-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 floor. 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 different room modes
are excited at different levels. Positioning
the subwoofer close to a corner will boost
the bass level at lower frequencies and may
cause asymmetrical spatial imaging.
ISS TM Autostart
The automatic power saving function ISS
(Intelligent Signal Sensing) can be activated
by setting the “ISS” switch on the connector 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 ISSTM
function can be disabled by setting the “ISS”
switch on the connector panel to “OFF.” In
this mode, the subwoofer is powered on and
off 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.
Setting The Playback Level
The rotary “SUBWOOFER LEVEL” level
adjustment can be used for matching the
subwoofer’s playback level with the main
loudspeakers.
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 loudspeaker array.
Two phase matching switches allow compensation for incorrect phase alignment.
Four settings are provided between 0° and
-270°.
Coarse Phase Correction
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 different 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.

Setting The Bass Roll-Off
Switches
The acoustic response of the subwoofer
may have to be matched to the characteristics of the room and the positioning in
which it will be used (see Table 1). To adjust
the subwoofer to match these characteristics use the ‘’BASS ROLL-OFF’ control
switches located on the connector panel.
When all Roll-Off switches are ‘OFF’, a flat
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 frequency. The phase difference between the

Matching IR Remote
Controls
The F One subwoofer can be used with
most IR remote controls, providing convenient use with, for instance, the remote
control of a TV set when connected to it
via a fixed level digital signal input. Turn the
subwoofer upside down so you can easily
reach the “Select” button on the subwoofer’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 actuate 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 approximately two seconds. This saves the settings 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
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 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, 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 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.

耐心,以及科学的实验和测试,能帮助您找到
最佳的摆放位置。
如 果 没 有 输 入 信 号,待 机 模 式 中 的 超 低 音
音 箱 仍 被 智 能 休 眠 功 能 激 活 。将 此 开 关 拨
至“O N”可 以 降 低 智 能 休 眠 功 能 的 触 发 灵
敏度。
超低音音箱的摆放位置也会影响低频下限以
及全频音箱与超低音音箱之间相位差。使用音
箱上的音色控制开关可以对上述问题进行补
偿,但我们建议您先将开关置于默认状态,专
注于找到超低音音箱频率响应最平直的位置
放置,然后再用音色控制开关调整音色、平衡
以及全频音箱与超低音音箱之间的相位。
降低智能休眠灵敏度
智能休眠
智能休眠功能会监控超低音音箱的输入信
号。
如果大约45分钟没有检测到输入信号,该
功能将会把音箱切换到待机模式,从而将功
耗降低到0.5瓦以下。
当输入信号恢复时,音箱
将被自动唤醒。自动唤醒的过程会稍有延时。
某些使用场景中要求超低音音箱一直处于工
作状态,则可以通过将智能休眠(ISS)开关拨
到“OFF”
,禁用智能休眠(ISS)功能。
音箱将会
保持在工作模式下,可使用遥控器或者接口面
板上的电源按键将其关闭。
LED关闭
此开关将禁用超低音音箱“脚”上的状态指
示灯。
低频滚降
这两个开关可衰减超低音音箱35Hz以下的低
首先,将超低音音箱靠近前墙中点放置,我们
建议超低音音箱与前墙的距离不超过 60 厘
米/ 24英寸。
由于这个位置靠近前墙和地面,这
样放置可以提高声学负载以及声压级。理想状
态下,超低音音箱和全频音箱都应该在房间中
对称放置,并且到听音者的距离相等。
如果频率均衡不合适,可以尝试将超低音音箱
放在沿墙面偏左或偏右的位置,激发不同的房
间模式。如果将超低音音箱靠近墙角放置,可
能会导致低音过重现象,造成声像不对称。
智能休眠自动启动
通过将接口面板上的智能休眠(ISS)开关拨
到“ON”
,可以激活智能休眠(ISS)功能。
当输
入信号停止播放一定时间后,音箱会自动进
入待机模式。
待机模式下的功耗通常小于0.5
瓦。
一旦从任意输入源检测到输入信号,音箱
将自动恢复工作。
此外,还可以通过按遥控器上的任何按键来启
动音箱。
自动唤醒的过程会有短暂延迟。如果不需要
此功能,可以通过将智能休眠(ISS)开关拨
到“OFF”
,禁用该功能。在此模式下,可使用遥
控器或者接口面板上的电源按键来开启和关
闭音箱。
“降低智能休眠灵敏度(ISS SENSITIVITY
LOW)”拨档开关可以降低智能休眠功能的触
发灵敏度。此功能在以下情况可能需要被打
开:即使没有输入信号,待机模式中的超低音
音箱仍被自动激活。
设置回放音量
超低音电平旋钮可用于调节超低音音箱和全
频音箱回放音量的平衡(注意,该旋钮仅改变
超F One的音量,不能控制全频音箱的音量)。
设置低频滚降开关
(Bass Roll-Off)
超低音音箱的声学响应与房间的声学特性和
摆位有关(参考表1)。
为了使超低音音箱与这
些因素相适应,可以使用接口面板上的“低频
滚降”开关。
所有的滚降开关默认处于关闭状
态,此时可在无反射声的消声室中获得平直的
响应。
设置相位控制
全频音箱与超低音音箱之间因距离不同而导
致的相位差,如果不经过校准,会导致回放内
容在全频音箱与超低音音箱的分频点处产生
抵消。
这种现象,源于听音者与全频音箱和超
低音音箱的距离差。为了避免左右声道与超
低音音箱的相位差,超低音音箱应该放置于
靠近前方音箱连线中点的位置。
两个相位匹配开关可以补偿不正确的相位耦
合,提供 0° 到 -270° 四档选择。
相位校准粗调
在超低音音箱的输入接口接入一个音频信号
发生器,在超低音音箱对应输出接口上连接
一只全频音箱。如果两只全频音箱到听音位
的距离不同,选择距离听音位较近的那只。
将信号发生器的频率调到 85Hz ,使超低音
音箱和全频音箱同时播放这一信号。如果没
有 音 频 信 号 发 生 器,也 可 以 使 用 一 段 含 有
70Hz 到 100Hz 的音频测试文件代替。您可
以在www.genelec.com 下载到合适的音频
测试文件,在某些智能手机中也能找到类似
的测试信号。

• 接下来,LED闪烁蓝色表明选择遥控器上
的“音源选择”按键。
• 黄色LED表明选择“静音”按键。
• 紫红色LED表明选择“电源”按键。
如果您不想让遥控器“学习”上面列出的所
有指令,短按音箱“选择”按键可以跳过一个
步骤。如果要中断整个过程,请按住“选择”
警告!
此设备可以产生超过 85dB 的声压级,这可
