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 dierent 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 than 1 W of 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 congured 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/amplier 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 certied Genelec dealers.

Connections

Before connecting signal cables, switch the

subwoofer amplier 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.

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 amplier unit and the

7382A subwoofer enclosure. There is a

corresponding connector on the reex port

end of the enclosure.

A 10 m (33.3 ft) cable is provided with the

so that its front panel light can not be seen.
All controls and calibration features included
in the 7382A SAM subwoofer are set using
the Genelec Loudspeaker Manager (GLM)
software. Two GLM Network connectors are

provided on the amplier for computer control.

These accept CAT5 or higher 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.

The main power connection supports a wide
mains voltage range (100-240 VAC, 50-60

Hz). This enables the RAM-SW amplier 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
filters are set in synchrony by the GLM
management network. This method is only
available in systems where GLM computer
management is used and with monitors
supporting this method. The subwoofer
crossover frequency can be adjusted from
50 Hz to 100 Hz.

The distributed bass management
supports three different signal cabling

congurations:

• 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

• 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 nd 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 (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’ denition 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 yellow warning
light appears, turn down the level.

Additional Information

Positioning the Subwoofer in a Room

The location of the subwoofer can affect
the frequency response and sound level
dramatically particularly when the room
acoustic effects are strong. Even small

changes in a subwoofer's location can

make a marked dierence in the frequency

response. To begin, place the subwoofer
near the front wall slightly offset from
the room center line. Often systematic
experimentation is needed to find the
location giving the flattest frequency
response at the listening location. Usually
the subwoofer is placed close to a wall as
this creates the highest output. Positioning
the subwoofer close to a corner will boost
the bass level at lower frequencies and may
also cause asymmetrical spatial imaging.

Measured from the subwoofer's driver the

recommended distance to a wall is less than

0.6 m (24 in). This avoids a loss of audio
level at low frequencies created by the audio

reecting o the wall and cancelling certain

frequencies radiated by the subwoofer.

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.

Do not cover the amplifier or place it in
a closed cabinet. The space must be

ventilated or suciently large to dissipate

heat so that the ambient temperature does
not rise above 35 degrees Celsius (95°F).
The reflex port opening on the enclosure
should have a clearance of at least 20 cm

(8 in) to ensure functioning of the reex port.

When the subwoofer is ush mounted in a

wall or cabinet, ensure unrestricted airow

in the reflex port and amplifier cooling.
Make the recess 20 cm (8 in) wider than the
subwoofer. Place the subwoofer to the right
side of the recess if the driver is facing the

room. This leaves sucient free space at

the reex port side. The height and depth of

the recess should not be much bigger than
what is needed as this may cause unwanted

acoustic eects.

Using Multiple Subwoofers

Multiple Genelec 7382A subwoofers can be
coupled together in high SPL applications.

The necessary cabling is dierent for digital

and analog signals. When subwoofers
are close to each other, the sound level
increases typically by 6 dB for each
doubling of the number of subwoofers.
When subwoofers are far from each other,
the total increase in the sound level can
be less. It is safe to assume the increase
is 3 dB for each doubling of the number of
subwoofers. Accurate understanding of the
increase in sound level requires acoustic
measurements.

Digital Cabling

Run a signal cable from the THRU AES/

EBU connector of the rst subwoofer in the

chain to the IN Digital connector of the next
subwoofer.
