Introduction
Congratulations and a thank you for the purchase of this Genelec
Smart Active Monitor (SAM) system. This manual addresses
the stand-alone setup and use of the 8340A and 8350A SAM
monitors. These monitors can also be set up and used with
the Genelec Loudspeaker Manager GLM™ and the proprietary
Genelec monitor control network and software, offering much
more versatile acoustic settings and features. Use with the
GLM™ is described in the GLM™ System Operating Manual.
All Genelec SAM systems are designed to integrate easily
into all professional environments, supporting both standard
analog line level audio and AES/EBU formatted digital audio
signals.
The 8340A and 8350A are suitable for professional monitoring
tasks demanding high precision and reliability of monitoring.
The Minimum Diffraction Enclosure™ (MDE™) and advanced
Directivity Control Waveguide™ (DCW™) technologies
provide excellent frequency balance even in difficult acoustic
environments.
Each monitor is supplied with a mains cable, one 5 m GLM
network cable and an operating manual.
Energy saving Intelligent Signal Sensing (ISS™) can be turned
on to put the monitor automatically into a deep sleep state
where the product consumes less than one Watt of power.
Upon sensing an input signal the monitor automatically wakes
up to full operation. The wait until entering the ISS power save
can be configured using the GLM software. When the ISS is
active you can have your monitoring system ready for action
at all times.
System setup using GLM™ Control
Network
Although the 8340A and 8350A can be used without the
GLM™ software and control network, they only reach their
full potential when set up and calibrated using the GLM™
software. Genelec Loudspeaker Manager GLM™ and the
proprietary Genelec monitor control network and software
offer automated acoustic equalization and alignment for any
reproduction system from simple stereo to very complex
3D immersive audio setups including also one or more
subwoofers. GLM setup is fast and accurate. The settings can
be controlled with a computer or be permanently stored in the
monitors to make the setup available at all times even when
a computer is not in use. Genelec recommends setting up
SAM monitoring systems using GLM. You can find a detailed
description of the setup and the use of GLM™ in the GLM™
System Operating Manual.
The setup is fast and consists of the following steps:
•  Connect a CAT5 (RJ45) cable between each monitor (and
subwoofer) and finally to the control network input of the
GLM Adapter device (see Figure 1).
•  Connect the GLM Adapter device to computer USB
connector.
•  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 of the
engineer’s ear. The microphone is a part of the GLM User Kit.
•  Connect the microphone cable to the microphone input in
the GLM Adapter device.
•  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 your monitors.
•  If you plan to not use a computer for controlling the
monitors, use the GLM software to write the setting into the
monitors (use menu item “Store | Store the Current Group
Settings…”).
While the GLM network is disconnected the settings stored
using the Genelec Loudspeaker Manager software can be
selected in use by setting the STORED switch ON.
Setup without using the GLM
When GLM is not available, you can use the settings on the
monitor for system setup. These settings are limited but provide
the basic acoustical calibrations and input selection. To use this
method, set the STORED switch OFF.
Connect the MAINS INPUT to the mains supply. These
products support any mains voltage globally (100-240 VAC,
50-60 Hz) so they can be plugged in anywhere. If the mains
power is provided with a generator, inverter or certain lower-
quality UPS devices, we recommend filtering of the mains
power voltage harmonics and taking care that the voltage
supply is stable.
The ANALOG IN connector is used for analog audio signals. The
maximum input level is +25 dBu. These monitors produce 100
dB SPL sound level at 1 meter in free space for an analogue
input signal of -6 dBu.
The DIGITAL IN AES/EBU female XLR connector is for AES/
EBU formatted digital audio input signals. This input is selected
automatically when a valid digital audio signal is present.
Analog input is selected when the AES/EBU signal input is
disconnected. The AES/EBU input supports two channels in a
single cable). When the digital source device controls the digital
output level, it may be advantageous to lower the level on the
monitor’s controls, which will enable the use of a higher digital
signal level with more digital resolution. With digital inputs the
audio is referenced to 0 dBFS (dB relative to the digital full scale,
the largest level that can be represented in the AES/EBU signal).

These monitors produce 100 dB SPL sound level at 1 meter in
free space for a digital input signal of –30 dBFS. The DIGITAL
OUT male XLR carries an unaltered copy of the digital signal fed
into the digital in connector. This enables daisy-chaining up to
four monitors.
The CONTROL NETWORK RJ-45 connectors are used with
Genelec Loudspeaker Manager™ (GLM™) network. These
connectors are not Ethernet LAN compatible. Do not connect
to Ethernet LAN.
Stand-Alone Control Functions
Bass Roll-Off Control
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.
Desktop 160 Hz
The desktop low frequency control (switch 5) attenuates the
bass frequencies around 160 Hz by 4 dB. This feature is de-
signed to compensate for the boost often occurring at this fre-
quency range when the monitor is placed upon a meter bridge,
table or similar reflective surface.
Bass Tilt Control
The Bass Tilt control switches (swiches 3 and 4) offer three at-
tenuation levels for the bass response below 800 Hz, usually
necessary when the monitors are placed near room boundaries.
The attenuation levels are -2 dB, -4 dB and -6 dB.
Treble Tilt Control
Treble Tilt control allows adjusting the treble response above 5
kHz by +2 dB, -2 dB or -4 dB, which can be used for correcting
an excessively bright or dull sounding system or to compensate
for high frequency level loss if the monitor is placed behind a
screen.
LED Disable
This switch shuts off the front panel LED light.
ISS
This switch activates or deactivates the ISS automatic power
saving function.
The default time for ISS activation is 60
minutes, but can be adjusted in GLM.
Digital
The Digital switch selects the digital audio channels on the
AES/EBU. Turning both switches on reproduces the sum of the
A and B channels. A 6 dB of attenuation is applied to avoid
overloading the monitor. If the AES/EBU cable is operated in
dual-wire mode, the monitor detects this automatically and the
channel selection switches have no effect.
Level
The Level switches scale down the monitor output level in 10 dB
steps. The effects of these switches add up and combine with
the effect of the rotary level adjustment control. The combined
total setting range is 42 dB.
Stored
Stored switch selects the use of the controls on the monitor’s
back panel or the settings stored inside the monitor memory
using the GLM system calibration software. Setting the Stored
switch to OFF position selects the settings defined by the
monitor’s own controls. Setting the Stored switch to ON position
selects the use of internally stored GLM settings. Using the
