System Description
The Genelec 7380A SAM subwoofer
integrates easily into environments based on
analog or digital interfacing. The 7380A even
introduces outstanding GLMâ„¢ features to the
lower octaves of monitoring systems based
on main speakers from a dierent vendor.
The 7380A is designed for precise monitoring
of multichannel analog audio signals and
stereo AES/EBU signals. Multichannel AES/
EBU signals can be monitored by using the
9301A multichannel digital audio interface
device connected to the subwoofer.
The subwoofer can be fully set up
using the controls built into the unit. The
7380A can also be precisely 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 7380A
consumes less than 2 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. When the ISS is active
you can have your monitoring system ready
for action at all times.
Package content
Each subwoofer is supplied with a mains
cable, one 5 m GLM network cable and an
operating manual.
Genelec Loudspeaker
Managerâ„¢ (GLMâ„¢) Software
And GLM User Kit
The GLM software gets the most out of
7380A 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 and monitors o.
Analog inputs 1 to 7
The 7380A 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 using the
+10 dB DIP Switch or in the GLM software.
AES/EBU input
One AES/EBU digital audio XLR input is
available on the 7380A 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 7380A 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.
Analog Output 1 to 7
Analog balanced XLR connectors connect
the subwoofer to monitors.
The 7380A SAM subwoofer supports two
bass management methods. Depending on
the chosen bass management method, these
analog outputs carry either unltered copy of
the inputs (SAM distributed crossover) or a
high-pass ltered signal (xed crossover).
The xed crossover is set to 85 Hz. The
SAM distributed crossover method allows
the subwoofer crossover to be adjusted in
the GLM software from 50 Hz to 100 Hz.
See chapter "Bass Management" for
details.
LFE Out
The analog LFE Out is a copy of the signal
at the analog LFE In. Typically, the LFE Out
is used in connecting to the LFE In of the
next subwoofer when multiple subwoofers
are used together.
Link Out
The sum of the analog inputs 1 to 7 is
available at the analog Link Out. The Link Out
is used in connecting to the next subwoofer
when subwoofers are used together while
using analog signals. See chapter "Using
Multiple Subwoofers."
Link In
The analog Link In accepts the signal from
the analog Link Out. The Link In input is used
when multiple subwoofers are used together
while using analog signals. When the Link In
is connected, the analog inputs 1 to 7 should
not be connected.
See chapter "Using Multiple Subwoofers."
OUT1 / Test 1
The analog OUT1 / Test 1 output XLR passes
a test tone for aligning the phase of the
subwoofer with a monitor.
This test tone has a frequency of 85 Hz
when the 7380A SAM subwoofer is set up
using the controls built into the subwoofer.
The test tone is enabled with the DIP Switch
labeled Test Tone. For more details on the
use of this output, see the section ‘Manual
Phase Alignment Method’.
OUT2 / Test 2
This analog output XLR is reserved for future
use.

AES/EBU Out
The AES/EBU Out is a bit-to-bit copy of
the digital audio signal on the AES/EBU IN.
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.
This can create a 2.1 digital audio stereo
monitoring system.
Bypass
The Bypass input accepts a 6.3 mm tip-ring-
sleeve (TRS) or tip-sleeve (TS) plug. This
plug supports a contact open/close switch
device. Connecting the TIP to the SLEEVE
activates the bass management bypass.
When the bass management bypass is
active, the subwoofer only reproduces the
LFE signal and the outputs bypassed to the
monitors are exact copies of the inputs.
The Bypass switch is intended to be used
when the subwoofer is set up using the
controls built in the subwoofer.
The GLM software control enables also
bypassing the bass management and oers
a wider set of controls and adjustments.
When the GLM is used, the TRS bypass
control is not needed.
GLM Management Network
All controls and calibration features included
in the 7380A SAM subwoofer can be set using
the Genelec Loudspeaker Manager (GLM)
software. Two GLM Network connectors are
provided on the subwoofer for computer
control. These connectors 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.
Mains Power Input
The main power connection supports a
wide mains voltage range (100-240 VAC,
50-60 Hz). This enables the 7380A SAM
subwoofer 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.

management methods: the centralized bass
management method and the distributed
bass management method.
