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 loudspeak

ers. 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 manage-

ment 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 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 amplier, no

separate power amplier is needed. Never

connect the F One to the loudspeaker out-

puts of a power amplier, integrated ampli-

er 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.

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 ne-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 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 One 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 One has two stereo inputs (3.5 mm

jack and L/R RCA connectors) and an LFE

RCA connector. The stereo inputs are par

allel, 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 lter, so it is

not suitable for full frequency range signals.

Digital Input Connectors

The F One has two digital signal input con-

nectors, 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 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.

Functions And Controls

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 One. In this mode

the volume control of the F One does not

have effect on the analog signals. However,

it works with the digital inputs, so you can

use them to connect other signal sources.

ISS Sensitivity Low

If the Intelligent Signal Sensing (ISS) func-

tion switches the subwoofer on when there

is no audio signal present, turning this

switch to “ON” reduces the triggering sen

sitivity of the function.

ISS

The Intelligent Signal Sensing (ISS) func-

tion 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 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 sub-

woofer’s bass response below 35 Hz.

Attenuation levels are -2, -4 and -6 dB

(both switches “ON”).

Phase

These two switches provide phase adjust-

ment for the subwoofer in -90 degree incre-

ments. See chapter “Phase Alignment”.

Subwoofer Level

This rotary adjustment adjusts the play-

back level of the subwoofer. The level is

increased by turning the adjustment clock

wise and reduced by turning it counter-

clockwise.

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 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 experi

mentation and testing is needed to nd 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 compen-

sated 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 acous-

tic loading and sound pressure level due to

the proximity of the front wall and oor. Ide-

ally 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

VOLUME

POWER

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

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 acti-

vated 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

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.

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-Off 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 difference 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 com-

pensation for incorrect phase alignment.

Four settings are provided between 0° and

-270°.

Coarse Phase Correction

Method

Connect an audio frequency signal gen-

erator 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 gen-

erator 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.

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 setting.

Matching IR Remote

Controls

The F One 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

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, 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.

低频滚降

这两个开关可衰减超低音音箱35Hz以下的低

音部分。可以获得-2dB, -4dB以及-6dB（两个

开关均设为ON）的衰减量。

相位

这两个开关以90度的增量为超低音音箱提供

相位调节。

超低音音量

此旋钮可调节超低音音箱的回放音量。顺时

针旋转为增大音量，逆时针旋转为减小音量。

选择

此按键用于在两个数字输入和模拟输入之间

进行切换，还可用于配对红外遥控器（请参阅

配对红外遥控器）。

电源

此按键可使超低音音箱在待机和工作模式之

间切换。请注意，此按键不会完全断开音箱电

源。如需断电，必须断开音箱的电源线。按住

此按键10-15秒钟，可使音箱恢复出厂设置。

该操作会将遥控器上的音量恢复为出厂设

置，并删除可能储存在音箱内的遥控器配对

记忆和红外遥控器配对记忆。信号源的选择

也会返回到出厂状态下的自动选择。

超低音音箱的摆放位置

由于低音受房间声学的影响较大，因此，超低

音音箱在房间中的摆放位置会影响整个系统

的频率响应以及音量。有时，稍许改变超低音

音箱的摆位，即可产生显著的频率响应变化，

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。

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。

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

红外遥控器匹配

F One超低音音箱可与大多数红外遥控器配

合使用，例如，将电视机的数字音频输出（通

常是光纤，且音量不可调）接入F Two，而后通

过电视机遥控器控制音响系统的音量。将超

低音音箱倒置，这样您就可以轻松地操作超

低音音箱接口面板上的“选择（Select）”按键，

并且可以看到超低音音箱“脚”上的LED指示

灯状态。红外接收器位于LED中。请注意，音

箱随机附送的射频遥控器上的“选择”按键无

法提供红外配对功能。

配对步骤如下：

• 按住超低音音箱上的“选择（Select）”按

键，直到 LED状态指示灯开始闪烁红色。

• 按遥控器上“增大音量”功能的按键，直到

LED停止闪烁。对于某些遥控器，多次点击按

键更容易匹配。

• 此时LED闪烁绿色，表示可以选择“减小音

量”的按键。请重复执行上述步骤。

• 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”

按键大约2秒钟。这将保存目前为止已做的

设置。如果您不想保存设置，请按住电源键2

秒钟。这将删除到目前为止已做的所有配对

设置。如果要更改已配对的按键，只需重新

配对即可。

射频遥控器配对

随机附送的遥控器可以控制任意一只F One超

低音音箱。如果不想随意配对，比如用户需要在

同一个环境下使用多只F One超低音音箱，且希

望每个遥控器只控制一只音箱，遥控器可以与特

定的F One配对。

1. 长按超低音音箱上的“电源”和“选择”按键，

直到LED开始闪烁白色。

2. 当LED闪烁时，先按住遥控器上的音量“+”

按键，然后按住音量“-”按键。同时按住两个

按键几秒钟，直到超低音音箱上的LED状态

指示灯停止闪烁。这表明配对已完成，配对操

作结束。

此时，超低音音箱仅响应已配对的遥控器发出

的命令，已配对的遥控器不能与其它F One音

箱一起使用。当在LED闪烁时取消配对操作，

请按住超低音音箱上的“电源”按键2秒钟。如

果您希望完全取消配对，请按住超低音音箱上

的“ 电源 ”按键 10秒钟。

请注意：当本地WIFI网络和射频遥控器在相同

的频率下工作时，有可能会导致射频遥控器工

作异常。在这种情况下，我们建议使用红外遥

控器。
