Genelec 1237A and 1238A Operating Manual
Introduction
Congratulations and a thank-you for the pur-
chase of this Genelec Smart Active Monitor-
ing (SAM) Series DSP monitor loudspeaker.
This product should be set up using the
fully automatic process in the Genelec Loud-
speaker Manager GLMā„¢ software. There are
no setup controls on the ampliļ¬er panel.
This manual describes the basic setup of
the monitor for use with the GLM software, as
well as use in the Stand-alone mode without
the GLM software in use or permanently con-
nected for computer control.
Each monitor is supplied with a mains
cable, one GLM control network cable, and
an operating manual.
System
The Genelec 1237A and 1238A are three-way
monitoring systems for medium sized control
rooms. They perform well as free-standing
monitors as well as ļ¬‚ush-mounted in control
room walls. They are suited for recording, ļ¬lm
and video post-production, broadcast moni-
toring as well as for mastering.
The unique Directivity Control Waveguideā„¢
(DCWā„¢) technology by Genelec provides
excellent stereo imaging and neutral fre-
quency response even in difļ¬cult acoustics.
With program material at a 2 meter listen-
ing distance, the fast low distortion ampliļ¬ers
drive a stereo system to peak sound levels
in excess of 122 dB SPL (1237A) or 124 dB
SPL (1238A).
The 1237A and 1238A are fully compatible
with Genelec Loudspeaker Manager GLMā„¢
and proprietary Genelec control network.
They can be used with 8200-series SAM
monitors and 7200-series SAM subwoofers
in the same network.
Drivers and Cabinet
Construction
The 1238A reproduces low frequencies with
a 385 mm (15 in) woofer in a 110 litre bass
reļ¬‚ex enclosure. The 1237A features a 305
mm (12 in) woofer in a 65 litre bass reļ¬‚ex
enclosure. Both monitors use the same pro-
prietary 130 mm (5 in) direct radiating mid-
range driver, and a 25 mm (1 in) metal dome
tweeter, both acoustically loaded by the pro-
prietary Directivity Control Waveguide. All
drivers are magnetically shielded.
Amplifiers and Signal
Processing
The 1237A and 1238A use the RAM-L ampli-
ļ¬er unit. The RAM-L is mounted with vibration
absorbers in the rear of the monitor enclo-
sure, and can also be detached and mounted
to a 19 inch rack. Digital signal processing
in the RAM-L ampliļ¬er unit is done with high
precision algorithms, and includes driver
and ampliļ¬er overload protection. The room
response compensations include highly ļ¬‚ex-
ible parametric ļ¬lters, level alignment, and
acoustic delay compensation. These allow
accurate matching to all console output sec-
tions and room acoustics.
Mounting Considerations
Place monitors so that their acoustic axes are
aimed towards the listening position (see Fig-
ures 1 and 2). Place monitors with left-right
symmetry and at an equal distance from the
listening position. Acoustic reļ¬‚ections from
objects close to monitors and the listening
position can cause colouration and blurring
of the sound image. Symmetrical positioning
of reļ¬‚ective objects maintains good stereo
imaging. When sofļ¬t (ļ¬‚ush) mounting, the
wall surface should extend to the monitor,
forming a continuous surface.
Minimum Clearances
The minimum clearance is 5 cm (2 in) behind,
above and on both sides of the monitor, when
the RAM-L ampliļ¬er is mounted on the enclo-
sure. The ambient temperature around the
ampliļ¬er must not exceed 35 degrees Cel-
sius (95Ā°F). When sofļ¬t mounting, sufļ¬cient
ventilation should be a arranged behind the
monitor. This may require forced ventilation
around the RAM-L ampliļ¬er.
When the RAM-L ampliļ¬er is mounted
in a 19 in rack, the minimum free space
is 1U both above and below the ampliļ¬er
and both sides of the ampliļ¬er fully open
to enable free movement of air. Use the
included rack mount front plate to ensure
sufficient space above and below the
ampliļ¬er.
When the RAM-L is mounted on a table,
shelf or similar solid surface, there must be a
free space of at least 250 mm (10 in) above
and 10 cm (4 in) on both sides of the ampli-
ļ¬er. Free air ļ¬‚ow must be possible in the front
side of the ampliļ¬er.
Set-up and Use
Monitor calibration and setup
The 1237A and 1238A are set up using the
GLM software. The setup is fast and consists
of the following steps:
1. Run a CAT5 (RJ45) cable from the mon-
itor control network to the next monitor.
2. Run the ļ¬nal 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 micro-
phone at the listening location of the engi-
neer, 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 micro-
phone 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 monitors, use the GLM
software to write the setting into the
monitors ("Store the Settings").
Recommendations for
AES/EBU Audio
For a digital input signal of ā€“30 dB FS, the
1237A and 1238A monitors will produce a
100 dB sound level (SPL) at 1 meter distance,
in free space. The sensitivity of the monitor
system is set using the GLM software.
It is advantageous to keep the maximum
incoming digital audio signal level high, near
to 0 dBFS. It may be useful to lower the inter-
nal GLM level control. This enables maintain-
ing high digital resolution in the digital source.
Single-wire mode of AES/EBU is the
default and the older dual-wire mode is auto-
matically detected if used at the source.
The standard AES/EBU cable carries two
channels of audio, called A and B. As a default,
ā€œDIGITAL THRU AES/EBUā€ Connector
This output carries an unaltered copy of
the digital audio signal and can be used for
daisy-chaining the signal up to three addi-
tional SAM monitors or subwoofers.
ā€œANALOG INā€ Connector
The maximum input level of the analog input
is +25.0 dBu. The analog input must not be
overloaded, otherwise distortion will result.
When the maximum input is exceeded, the
enclosure front panel light turns red, indicat-
ing the overload.
The sensitivity of the monitor system is
set using the GLM software. Coming from
the factory, the analog input is set to the
highest sensitivity, resulting in a sound
output of 100 dB SPL for a -6 dBu analog
input signal.
ā€œCONTROL NETWORKā€ Connectors
The RJ-45 sockets connect the monitor to
the proprietary Genelec Loudspeaker Man-
agerā„¢ (GLMā„¢) network. Do not connect to
Ethernet LAN.
ā€œLoudspeaker Connectorsā€ Group
These connectors are used when the RAM-L
ampliļ¬er is mounted separately in an equip-
ment rack.
1. ā€œLEDā€ Connector
This RJ-45 socket is a connection for
the front panel warning LED.
2. ā€œWooferā€ Connector
A standard four-pole Speakon cable
connects to the woofer.

both A and B subchannels are reproduced by
the monitor. GLM software is used to set up
the monitor to speciļ¬c channel assignments.
RAM-L Amplifier
Power Button
The power button in the middle of the RAM-L
ampliļ¬er front panel controls several functions.
A short press of the power button turns
RAM-L on or off. Turning on, the power button
light ļ¬‚ashes rapidly, and lights on steadily
when the turn-on has been completed.
Testing modes are explained later in this
manual.
Setting ISSā„¢
The Intelligent Signal Sensing (ISS) puts the
monitor to a power-saving stand-by mode
automatically. The factory setting for ISS is
"OFF." The ISS can be activated using the
GLM software (see Figure 5). When ISS is
active, if no audio signal is sensed during
the selected time, the monitor powers down.
The monitor will power up again once a
signal is detected. The ISS setting is applied
to all ISS-enabled monitors in the currently
selected Setup.
Connections
ā€œMAINS INPUTā€ Connector
Connect to the mains supply.
ā€œDIGITAL IN AES/EBUā€ Connector
The monitor defaults to reproducing an
analog input signal. The digital audio AES/
EBU input is selected automatically when a
valid digital audio signal is presented. Use
GLM software to deļ¬ne the AES/EBU sub-
frame to monitor.
