System Description
The Genelec 7382A SAM subwoofer is
designed for professional use and integrates
easily into environments based on analog or
digital interfacing. The 7382A even introduces
outstanding GLM™ features to the lower
octaves of monitoring systems based on
main speakers from a dierent vendor.
Multichannel AES/ EBU signals can be
monitored by using the 9301A multichannel
digital audio interface device connected to the
subwoofer.
The 7382A is intended to be calibrated
to the monitoring room acoustics using
the Genelec Loudspeaker Manager (GLM)
computer software. The GLM software
runs on Mac OS and Windows computers
and enables detailed acoustic calibration
permanently inside the subwoofer. It is
also possible to use the GLM software as
a monitoring management system for more
than 30 SAM monitors and subwoofers.
In its power save mode, the 7382A
consumes less power. Energy saving
Intelligent Signal Sensing (ISS) can
automatically put the subwoofer into a
power save mode when audio has been
absent for a selected time. Upon sensing an
input signal, the subwoofer wakes up to full
operation. The time before entering the ISS
power save mode can be congured using
the GLM software.
Package content
Each subwoofer is supplied with an
individually calibrated RAM-SW amplifier
unit. If several 7382A subwoofers are used
in the same system, it is very important
not to mix the subwoofer/amplier pairs. A
mains cable, a 10 m (33.3 ft) Speakon signal
cable, one 5 m GLM network cable and this
operating manual are also included.
Operating Environment
This subwoofer is designed for indoor use
only. The permissible ambient temperature
is 15-35 degrees Celsius (50-95°F) and
relative humidity 20 – 80% (noncondensing).
When the product has been stored or
transported in a cool environment and is
taken into a warm room, wait about one
hour before opening packing to prevent
condensation of humidity before connecting
to mains power.
Genelec Loudspeaker
Manager™ (GLM™) Software
And GLM User Kit
The GLM software gets the most out of
7382A and tailor-ts it to your room. GLM
is available for download free of charge at
www.genelec.com/glm. Check in from time
to time to take advantage of 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 certied Genelec dealers.
Connections
Before connecting signal cables, switch the
subwoofer amplier and monitors o.
Analog Inputs 1 and 2
The 7382A SAM subwoofer accepts
balanced XLR inputs. These are the outputs
typically provided in a console or a monitor
controller. The maximum balanced audio
signal level is +24 dBu.
LFE In
A dedicated XLR input is provided for the
analog LFE signal. The bandwidth for a signal
fed to the LFE input is 120 Hz. The LFE input
sensitivity can be set the same as for the
main channels or at +10 dB relative to the
main channels. This feature is set in the GLM
software.
IN Digital
One AES/EBU digital audio XLR input is
available on the 7382A subwoofer. This can
take a stereo digital audio signal.
Multichannel digital audio monitoring is
possible with the 9301A interface device.
The 9301A connects to the digital audio
input in the 7382A subwoofer and expands
the number of digital audio inputs to four
XLR digital audio inputs. This supports a 7.1
audio system, including an LFE channel. For
more subs not playing the same signal, e.g.
Table 1. Recommended cable gauges for
dierent lengths of signal cable.
in large immersive installations with bass
management of surround channels, one
9301A is required per 7382A.
Analog Output 1 and 2
Analog balanced XLR connectors connect
the subwoofer to the monitors.
These analog outputs carry an unltered
copy of the inputs. The subwoofer/main
monitor crossover is adjusted in the GLM
software from 50 Hz to 100 Hz in 5 Hz
increments.
See chapter "Bass Management" for
details.
THRU AES/EBU
The THRU AES/EBU is a bit-to-bit copy of
the digital audio signal on the IN Digital. This
output can be used for digital sharing of the
audio between subwoofers in the case where
multiple subwoofers are used. This output
can also be used for distributing a stereo
digital audio signal to monitors, creating a
2.1 digital audio stereo monitoring system.
Subwoofer Connector
This Speakon connector is used for
linking the RAM-SW amplier unit and the
7382A subwoofer enclosure. There is a
corresponding connector on the reex port
end of the enclosure.

1) Additional subwoofers of the same type may be required in a larger room with bass heavy program
material.
2) Subwoofers are not necessarily required for a 1236A installation as these monitors are already full
range. For immersive systems, subwoofers can be used to reproduce the LFE channel.
Table 2. Recommended subwoofer/main monitor combinations.
A 10 m (33.3 ft) cable is provided with the
subwoofer. See Table 1 for recommended
minimum gauges for different lengths of
cable. Four pole cable is recommended. The
cable connectors are connected pin to pin,
with 1+ and 2+ in parallel, same as 1- and 2-.
GLM Management Network
All controls and calibration features included
in the 7382A subwoofer are set using the
Genelec Loudspeaker Manager (GLM)
software. Two GLM Network connectors
are provided for computer control. These
accept CAT5 or higher category cable (RJ45
connector). Standard CAT cables can be used.
The GLM management network runs a
proprietary protocol. This is not an Ethernet
connection, do not connect to an Ethernet
network.
LED Connector
This connector allows linking a remote status
indicating light if the amplier unit is placed
so that its front panel light can not be seen.
Mains Power Input
The mains power connection supports a
wide mains voltage range (100-240 VAC,
50-60 Hz). This enables the RAM-SW
amplier to be plugged in anywhere globally.
When the mains power is provided with a
generator, inverter, or certain lower-quality
UPS devices, we recommend ltering power
to remove harmonics and ensuring the
voltage supply is stable.
Bass Management
Bass management divides the input audio
signal into low frequency and high frequency
content at the subwoofer crossover frequency.
The signal content below the crossover
frequency is reproduced by the subwoofer.
The signal content above the crossover
frequency is reproduced by the monitors.
In the distributed bass management
method used in the 7382A system, the
monitors and the subwoofer receive full
banwidth audio signal and the filtering is
done separately inside each monitor and
subwoofer. The lowpass and highpass lters
are set in synchrony by the GLM management
network. This method is only available in
systems with GLM computer management
and with monitors supporting GLM. The
crossover frequency can be adjusted from
50 Hz to 100 Hz in 5 Hz increments.
The distributed bass management
supports three different signal cabling
congurations:
All channels are routed through the
subwoofer's IN/OUT connectors to the
respective monitors.
• Y-cables split each signal to the
subwoofer's IN connector and the
monitor's input.
• Signal sources with dual outputs for each
channel, one going to the subwoofer, the
other going to the monitor.
Use With GLM Control
Network
The 7382A SAM subwoofer is fully
compatible with Genelec Loudspeaker
Manager GLM software, the proprietary
Genelec monitor management network, and
all Genelec SAM monitors.
Managing the 7382A SAM subwoofer
using GLM software control unleashes
the full power of room compensation in
the 7382A SAM subwoofer, enabling 20
parametric room compensation lters. This
powerful room compensation functionality
is only available when the GLM is used.
Detailed information on the use with the
GLM network is presented in the GLM
System Operating Manual.
System Setup
The 7382A SAM subwoofer reaches its full
potential when set up and calibrated using
the GLM software. Genelec Loudspeaker
Manager GLM and the proprietary Genelec
monitor management network oer
• automated acoustic equalization
individually for every monitor and
subwoofer
• automated level alignment
• distance (acoustic time-of-ight)
calibration
• aligning of the subwoofers for bass
management
for any reproduction system from stereo
to complex 3D immersive setups, including
one or more subwoofers. GLM setup is
fast and accurate. It can precisely address
the typical narrow-band low frequency
modal resonances and radiation loads
of a room and offers precise frequency
response compensations. The settings
can be controlled with a computer or the
settings can be permanently stored in the
monitors and subwoofers, to make the
setup available at all times even when
the computer is not in use. Genelec
recommends setting up SAM monitoring
systems using the GLM. You can find a
detailed description of the setup process
and the use of GLM in the GLM System
Operating Manual.
The setup using GLM is fast and consists of
the following steps:
• Connect a CAT5 or higher category
(RJ45) cable between each monitor (and
subwoofer) and nally 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 GLM Adapter device to the
computer USB port using cable included
in the GLM User Kit.
• 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 system.
• If you plan to not use a computer for
controlling the subwoofer, use the GLM
software to write the setting into the
subwoofer (use menu item “Store | Store
the Current Group Settings…”).
With GLM software active and controlling
the 7382A SAM subwoofer, the use of
analog and digital inputs is controlled by
the GLM software entirely. In the software
‘Input Type’ in the ‘Group’ denition sets
this. The GLM software allows you to select
and switch between the analog and digital
audio inputs.
If GLM control is not used, an AES/EBU
digital audio signal will override analog
signal. This means, if a valid digital audio
clock is detected, the digital audio is
selected over the analog audio.
When the GLM acoustic settings have
been stored in the 7382A SAM subwoofer
and are active, the input is selected by the
‘Group’ settings in the GLM software when
the settings are stored.
RAM-SW Power Switch Light
When used without a connection to the
GLM software, the light on the power
switch on the RAM-SW is green, indicating
normal operational mode. A red colour
indicates amplifier clipping and yellow
indicates thermal overload. If the red or
