A pair of nearly invisible woofers in the 8341A are placed acousticallycoaxially with the midrange/tweeter drivers to create a three-way
system with all drivers having their acoustical axes in the same
position. This creates an ideally working point source radiator.

System Characteristics
Each 8341A is supplied with one mains power cable, one
5-meter GLM network cable and this operating manual.
The Genelec 8341A is suitable for professional monitoring
applications calling for very high precision and reliability.
It combines many remarkable Genelec technologies toprovide point source benefits with directivity control over an
extraordinarily wide audio bandwidth.

Genelec Loudspeaker Manager™ (GLM™)
Software And GLM User Kit
The GLM software gets the most out of 8341 and tailor-fits it toyour room. GLM is available for download free of charge at www.
genelec.com/glm. Check in from time to time to take advantageof new features, or consider using the cloud-based version. A
GLM User Kit comprising the necessary hardware, including the
GLM Adapter and measuring microphone is needed for building
and operating the GLM network. This kit can be purchased at all
certified Genelec dealers.

Minimum Diffraction Coaxial (MDC™)
The minimum diffraction coaxial driver is comprised of a powerful
midrange driver combined with a tweeter driver extending toultrasonic frequencies. This unique arrangement eliminates orminimizes acoustic diffraction sources that typically exist in
coaxial drivers and produces a flat frequency response both on
the acoustical axis and at all off-axis directions.
The 8341 may be oriented either horizontally or vertically andis intended for near-field listening where the influences of theroom can be mostly minimized. Typical distances can vary from
1 meter or less to 3 meters depending on room size and SPL
requirements.

Directivity Control Waveguide (DCW™)
The 8341A has an unusually large directivity control waveguide
extending over the whole front face of the enclosure. The
midrange driver cone also forms a part of the directivity control
waveguide for the tweeter. From behind the waveguide, twowoofers radiate audio through two openings in the enclosure
front. This unique design enables directivity control of all audio
frequencies down to low bass.

Smart Active Monitor (SAM™)
Genelec SAM technology can improve the reliability and accuracyof monitoring. Smart Active Monitors have several parametricnotch and shelving filters that can be tuned automatically using
the Genelec Loudspeaker Manager (GLM) software to exactlycompensate for colorations generated by room acoustics. This
enables SAM monitors to sound neutral and achieve accuratestereo imaging in all acoustical environments.

Audio Inputs
The 8341A’s audio inputs are designed to integrate easily into all
professional environments, supporting balanced line level analog
and AES/EBU format digital signal. The maximum analog input
level is +25 dBu (13.7 Vrms or 19.5 V peak). Set to the maximum
sensitivity, an analog input signal of -6 dBu produces 100 dB SPL
sound level at 1 meter in free space. A -30 dBFS digital audio
input level produces 100 dB SPL level at 1 meter in free space.
Note that 0 dBFS refers to the largest possible digital input value.
Analog input is selected when the AES/EBU signal input is notconnected. The AES/EBU format digital audio input is selected
automatically when a valid digital audio signal is present. Please
note that this digital audio signal may be silence. This automatic
audio signal input selection can be overridden when the 8341A
is controlled with the GLM network, enabling flexible selection ofeither input.
When using a digital audio source with adjustable level, it
may instead be advantageous to lower the output level of the
8341A using the monitors on-board rear panel controls. This
enables the use of a higher source output level with more digital
resolution, while taking full advantage of 8341’s impressively low
self generated noise.
The AES/EBU input supports two channels of audio in a single
cable. The DIGITAL OUT male XLR connector carries an unalteredcopy of the digital input signal. This enables daisy-chaining of up
to four monitors. The proper digital channel can be selected using
DIP switches or GLM.

Power Management
The 8341A mains power input supports any mains voltage globally(100-240 VAC, 50-60 Hz). It can be plugged in anywhere in theworld and will always deliver the maximum output power to thedrivers even when the mains voltage fluctuates. If mains power isprovided with a generator, inverter or lower-quality UPS device, we
recommend filtering out harmonics from the mains power voltage.
The energy saving function Intelligent Signal Sensing (ISS™)
puts the monitor automatically into a deep sleep state when
no input signal is present. The device then consumes less than
one watt of power. Upon sensing an input signal, the monitor
automatically awakens. The wait time until entering the powersaving state can be configured using the GLM software. WhenISS is active, you can leave your monitors on at all times and havethe monitoring system immediately ready for action. The default
wait time when ISS is enabled using the ISS DIP switch is 60
minutes.

Setup Using The
GLM™ Control Network
Although the 8341A can be used without the GLM software andcontrol network, it can only reach its full potential when set up
and calibrated using GLM software, running on a Mac or PC.
Genelec therefore recommends setting up the 8341A
and other SAM monitors using GLM. You can find a detailed
description of the setup and the use in the GLM System
Operating Manual.
The GLM software and the proprietary Genelec monitor
control network offer automated acoustic equalization and

alignment for any reproduction system from mono over stereo
to complex 3D immersive audio setups, including also one ormore subwoofers. GLM includes AutoCal, an expert algorithm
built on data from thousands of professional listening rooms.
Setup with the GLM User Kit consists of the following steps:
1. Connect a CAT5 (RJ45) cable between each monitor (andsubwoofer) and finally to the control network input of the
GLM Adapter device (see Figure 1).
2. Connect the GLM Adapter device to computer USB connector.
3. Using a microphone stand, place the Genelec measurement
microphone at the listening location with the microphone
pointing upwards and the microphone top at the height ofthe engineer’s ear. The microphone is a part of the GLM
User Kit.
4. Connect the microphone cable to the microphone input in
the GLM Adapter device.
5. Download the GLM software at the Genelec web site (www.
genelec.com). Install the GLM software and follow the

instructions in the software to measure and set up yourmonitors.
6. If you plan to not use a computer for controlling themonitors, use the GLM software to write the settings into
the monitors (use menu item “Store | Store the Current
Group Settings…”).
The GLM network may also be used for monitor control switching between sets of loudspeakers, solo, mute, invoking
calibrated levels etc. - or settings can be permanently stored in
all monitors for a static and predictable setup. If so, a computeris only needed for the setup.
If the network is disconnected, settings stored using the GLM
software can be enabled by setting the DIP switch “Stored” to ON.
The CONTROL NETWORK RJ-45 connectors are used for
the GLM network. These connectors are not Ethernet LAN
compatible. Do not connect to an Ethernet LAN.

Setup Without Using The GLM
When GLM is not available, you can still adjust the 8341A for
placement in a room by using the DIP switches on the back of themonitor. Settings are more limited but nevertheless provide thefundamental equalizers to compensate for the acoustical effectsof the listening room, input selections and input sensitivity. To use
this method, ensure that the GLM management network is notconnected and set the DIP switch “Stored” to its OFF position.

Stand-Alone Control Functions
Bass Roll-Off Control
The Bass Roll-Off control attenuates the monitor’s output near
the cut-off frequency. Attenuation levels of -2 dB, -4 dB or -6 dB(both switches ON) can be selected by combining settings on
one or more switches. This setting may be needed to control thebass level in spaces with strong low frequency reverberance.

Figure 5. Symmetrical layout and keeping the acoustic axis clear
from obstructions minimizes reflection surfaces and maintains
accurate localisation because reflections are symmetrical.

placement positions.

Bass Tilt Control
The Bass Tilt control switches offer three attenuation levels forthe bass response below 800 Hz. The attenuation levels are -2
dB, -4 dB and -6 dB (both switches ON). This control is usuallynecessary when the monitors are placed near room boundaries
such as at the wall or close to a room corner.

Treble Tilt Control
The Treble Tilt control allows adjusting the high frequency
response above 5 kHz by +2 dB, -2 dB or -4 dB, which canbe used for correcting an excessively bright or dull sounding
system or to compensate for the high frequency level loss whenthe monitor is placed behind a screen.

LED Disable
This switch shuts off the front panel LED light.

Desktop reflection compensationISS

The desktop low frequency control attenuates the bass
frequencies around 160 Hz by 4 dB. This feature is designed tocompensate for the boost occurring often when the monitor isplaced upon a meter bridge, table or similar reflective surface.

This switch activates or deactivates the ISS automatic powersaving function. The default time for ISS activation is 60 minutes,
but the time can be adjusted in the GLM software.

Table 2. Monitor front panel light indications summary

DigitalThe Digital switch selects the digital audio channels on the
AES/EBU. Turning both switches on reproduces the sum of the
A and B channels. When both channels are selected 6 dB ofattenuation is applied to avoid overloading the monitor.

Level
The Level switches reduce the monitor output in 10 dB steps(-10 dB, -20 dB and with both switches set to ON, -30 dB). The
effects of these switches combine with the effect of the rotarylevel adjustment control. The total setting range is 42 dB.

StoredThe Stored switch selects between the application of theabove listed controls on the monitor’s back panel and applying
the settings stored inside the monitor memory using the GLM
calibration software. Setting the Stored switch to the OFF position
selects the settings defined by the monitor’s controls. Setting theStored switch to ON position selects the use of internally stored
GLM settings and the adjustments on the monitor have no effect.

Operating Environment
This product is designed for indoor use only. The permissible
ambient temperature is 15-35 degrees Celsius (50-95°F) andrelative humidity 20% to 80% (non-condensing). To prevent
condensation of humidity, after the product has been stored
or transported in a cool environment and is then taken into a
warm room, wait 0.5-1 hours before opening the packaging andconnecting to the mains power.
Sufficient cooling around the 8341A must be ensured. The
minimum clearance behind, above and on both sides of themonitor is 50 mm (2 in). If the product is installed in a recess,the space must be ventilated sufficiently to dissipate the heat.

Mounting And Placing Monitors
Mounting Options
The vibration insulating Isolation Positioner/Decoupler™
(Iso-Pod™) table stand allows tilting of the monitor. The
stand spring can be attached to three mounting points on
the 8341A enclosure, allowing the Iso-Pod to be used on
one vertical and two horizontal positions. With horizontal
positioning, the Iso-Pod must be at it’s furthest forward
position (See Figure 6).

Figure 6. Placing the Iso-Pod stand when the monitor is used inhorizontal position.

Aim the monitor so that its acoustic axis points towards thelistening position (see Figure 4). Place the monitors symmetricallyat equal distances from the listening position. If possible, place
the listening position on the left-right centerline of the room(see Figure 5). When a monitor is placed far away (1.0-2.2 m,
3-7 ft) from the acoustically hard wall behind the monitor, an
acoustic reflection from the wall may cause cancellation of low
frequencies and reduce the bass output.
Minimize reflections by placing the monitors away fromacoustically reflective surfaces. Acoustic reflections fromobjects like desks, cabinets and computer monitors cancause unwanted coloration and blurring of the sound image.
Putting the monitors on stands behind and above a mixing
console usually improves the response over placing monitors
on a meter bridge. Symmetrical positioning of the soundreflecting objects maintains a balanced soundstage (seeFigure 5).
A wide variety of ceiling and wall mounts are available
through your Genelec dealer. Genelec 8341A can be fitted with
König & Meyer monitor mounts using two M6 x 10 mm threadedholes on the enclosure back. There is an M10 x 10 mm threadedhole in the base of the monitor. Do not use the M10 thread for
mounting the monitor on a microphone stand. Monitor stands
typically have an incompatible 3/8 in UNC thread. Consult the
Genelec Accessories Catalogue at www.genelec.com or yourlocal distributor/dealer for information.

Front Panel Light
Normally, the light on the front panel is green, indicating normal
operational mode. Red and yellow colours are used to indicate
special situations. See Table 2.

Use With Subwoofers
In situations requiring deeper fundamental response or
multichannel bass management, Genelec recommends
using the 7300 series subwoofers. For more detailed system
configuration and matching products, please consult the on-line
Genelec Product Selection Tool at www.genelec.com.

Maintenance
There are no user serviceable parts inside the monitor.
Maintenance or repair must only be done by Genelec certified
service personnel. The monitor enclosure must not be opened.
Opening the monitor may lead to loss of the individual monitor
factory calibration and damage to components.

5Safety Considerations
Although the 8341A has been designed in accordance withinternational safety standards, to ensure safe operation andto maintain the monitor under safe operating conditions, thefollowing warnings and precautions must be observed:• Servicing and adjustment must only be performed bycertified Genelec service personnel. The monitor enclosuremust not be opened.
• Do not use this product with an unearthed mains cableor a mains connection without the protective earth contact
as this may lead to personal injury.
• To prevent fire or electric shock, do not expose the unit
to water or moisture.
• Do not place any objects filled with liquid, such as vaseson the monitor or near it.
• Note that the amplifier is not completely disconnectedfrom the AC mains service unless the mains power cord isremoved from the monitor loudspeaker or the mains outlet.
• Free flow of air behind and around the monitor isnecessary to maintain sufficient cooling. Do not obstruct
airflow around the monitor.

此时设置功能相对有限，仅能提供输入选择、灵敏度调整，以及基础的房间声学补偿设置。如需使用此模式，请确保GLM网络断开，同时将“Stored”DIP开关调至OFF状态。

单机控制功能低频滚降（Bass Roll-Off）控制

低频滚降（Bass Roll-Off）可以衰减低频截止点附近的低频。
使用一个或多个低频滚降DIP开关，可以获得 -2dB、-4dB以及-6dB（两个开关均设为ON）的衰减。
在低频混响较强的环境中，可能需要启

调音台表桥、桌面或类似反射面上时，使用该设置可以补偿这种摆
位带来的低频隆起。

低频搁架（Bass Tilt）控制

低频搁架（Bass Tilt）为800Hz以下的低频响应提供三种衰减设

置：-2dB、-4dB以及-6dB（两个开关均设为ON）。通常当音箱靠近房间边界时，如靠近墙或靠近角落，需要启用此设置。

高频搁架（Treble Tilt）控制

高频搁架（Treble Tilt）为5kHz以上的高频提供+2dB、-2dB和-4dB

三种设置。
当音响系统的高频过分明亮或暗淡时，或者音箱置于透
声幕后导致高频衰减时，需要启用此设置进行补偿。

0.5到1小时后再开箱使用。

侧方需留有最小50毫米（2英寸）的净空。如果音箱采用嵌入式安装，需保证有效的通风以供散热。

音箱的安装和摆放安装选项

Iso-Pod™桌面隔震音箱垫可以调节音箱的俯仰角度。
音箱垫的导

轨可以安装于音箱背板后三个不同安装点，实现水平和垂直摆放。
当音箱水平摆放时，Iso-Pod必须固定在导轨的最远端（见图6）。

音箱的声轴需指向听音位置（见图4）。将音箱对称摆放，确保每只音箱与听音位置等距。
如果可能，将听音位置设置在房间左右的中轴线上（见图5）。当音箱距离其后方的实墙1.0-2.2米时，墙面的反
射会造成低频的抵消，减少低音输出。

将音箱远离声学反射面放置以减弱反射声的影响。桌面、柜体、电
脑显示器等带来的反射声会造成不良的声染色以及声像定位模糊。
将音箱用支架放置在调音台后上方，通常会比放置在调音台表
桥上更理想。
另将声反射物体对称摆放，可以获得平衡的声像定位（见图5）。
