Introduction
Congratulations and a thank-you for the purchase of this Genel-
ec SAM system. All Genelec SAM systems are designed to in-
tegrate easily into the digital production environment. There are
several ways to configure and operate SAM systems for a wide
variety of high quality audio applications. The SAM monitors
also have analog inputs, making them versatile and intelligent
replacements for standard analog monitors.
This manual addresses the setup and use of the 8240A, 8250A,
8351A and 8260A SAM monitors in stand-alone mode without
the Genelec Loudspeaker Manager GLM™ and the proprietary
Genelec monitor control network. Use with the GLM™ is de-
scribed in the GLM™ System Operating Manual.
System
Genelec 8240A, 8250A, 8351A and 8260A are designed for
precise monitoring of 24 bit/192 kHz AES/EBU digital audio sig-
nal or line level analog audio signal. They are fully compatible
with Genelec Loudspeaker Manager GLM™ and the proprietary
Genelec monitor control network, and Genelec 7260A, 7270A
and 7271A SAM Subwoofers, but can also be used indepen-
dently of these. The 8240A, 8250A, 8351A and 8260A feature
high SPL output, low colouration and broad bandwidth in a small
enclosure size. They are suitable for a wide variety of tasks,
such as near field monitoring, mobile vans, broadcast and TV
control rooms, multichannel sound systems and home studios.
The Minimum Diffraction Enclosure™ (MDE™), advanced Di-
rectivity Control Waveguide™ (DCW™) and Minimum Diffrac-
tion Coaxial (MDC™) technologies provide excellent frequency
balance even in difficult acoustic environments.
Amplifiers
The amplifier unit is mounted in the rear of the monitor enclosure.
The unit incorporates special circuitry for driver thermal overload
protection. Variable input sensitivity allows accurate level match-
ing to console output section.
Setting Up the GLM™ Control Network
Although the
8240A, 8250A, 8351A and 8260A 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. The setup is fast and consists of the following steps:
1. Run a CAT5 (RJ45) cable from the monitor control network
to the next monitor (see Figure 1).
2. Run the final cable to control network input of the GLM
Adapter device.
3. Connect the GLM Adapter device to your computer USB
connector. The cable
is a part of the GLM User Kit
.
4. Place the Genelec measurement microphone at the listen-
ing location of the engineer, on a stand, with the microphone
pointing upwards and the microphone top at the height of the
engineers ear in normal working position. The microphone is
a part of the GLM User Kit.
5. Run the microphone cable to the microphone input in the
GLM Adapter device.
6. Download GLM software at the Genelec web site (www.
genelec.com). Install the GLM software.
7. Follow the GLM software instructions to measure and set
up your monitors.
8. If you plan to not use a computer for controlling the moni-
tors, use the GLM software to write the setting into the moni-
tors (“Store the Settings”).
Using the Monitors in Stand-Alone Mode
When the monitors are not connected to a Genelec monitor con-
trol network, they operate in the stand-alone mode. However, set-
tings made with the Genelec Loudspeaker Manager software can
be saved into each monitor and applied even when the network
is disconnected by setting switch 1 “STORED/MANUAL CON-
TROL” on switch group 2 of each monitor to position “STORED.”
All issues concerning use with the network are explained in detail
in the System Operating Manual provided with the GLM™ Loud-
speaker Manager software kit.
Connections
Each monitor is supplied with a mains cable, one 5 m GLM net-
work cable and an operating manual. Before connecting up, en-
sure that the mains switch is off.

“MAINS INPUT” Connector
Connect the mains supply to this connector.
“DIGITAL IN AES/EBU” Connector
Use this female XLR connector for AES/EBU formatted digital
audio input signals. This input is selected automatically when a
valid digital audio signal is present, and overrides the analog in-
put.
Depending on the digital hardware, transmission of a 192 kHz
sample rate is achieved using a double speed, single channel/
cable interface. This is called dual-wire mode. In this case one
cable per channel is used and no channel selection is required.
Dual-wire mode is automatically detected by the input stage.
If the digital source device has a volume fader that controls the
digital level, it may be advantageous to lower the level control
either on the computer interface or on the monitor’s back panel
controls, which in turn will force the use of more of the digital [bit]
resolution in the volume control.
If the digital inputs are used, all audio outputs are referenced to 0
dBFS (digital Full Scale, the largest level that may be represent-
ed in the AES/EBU signal). These monitors produce 100 dB SPL
at 1 meter in free space for a digital input signal of –30 dB FS.
“DIGITAL THRU AES/EBU” Connector
This male XLR carries an unaltered copy of the digital signal fed
into the “DIGITAL IN AES/EBU” connector. It can be used for
daisy-chaining up to four monitors together.
“ANALOG IN” Connector
Use this connector for analog audio signals. The maximum input
level is +7.0 dBu RMS on models 8240A and 8250A and +22.0
dBu RMS on models 8351A and 8260A. When A/D converter
input clip occurs the front panel light turns momentarily red, indi-
cating the overload condition.
“CONTROL NETWORK” Connectors
Use these RJ-45 sockets to connect the monitor to the propri-
etary Genelec Loudspeaker Manager™ (GLM™) network only.
This connector is not Ethernet LAN compatible. Do not connect
to Ethernet LAN.
“12 V REMOTE” Connector (8260A only)
You can set up remote controlled powering up and down of the
8260A with 12 V voltage connected to this connector. The mini-
mum current needed to actuate this function is 70 mA.
Front Panel Warning Light
Normally the light on the front panel of a SAM monitor is green,
indicating that the monitor is in normal operational mode.
The overload light (red) is activated by several events:
•  exceeding the maximum input range of the analog input
•  the digital input level is less than 0.1 dB from the digital full
scale
•  exceeding the output capacity of the power amplifier
(clipping in the power amplifier) and thermal
overload of the power amplifier or drivers (thermal
protection has activated)
•  an error is detected in the AES/EBU audio data
If a red warning light appears, turn the analog source down! If
the levels are already modest and a digital signal is being used,

layout but without the 12 V trigger voltage connector.
