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 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. For more subs not playing the same signal, e.g.

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 unltered
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 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 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 amplier 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
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 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
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.

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’ 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
