Introduction
Congratulations and a thank-you for the purchase of this Genelec 7300 series subwoofer. This manual addresses setting up and using the Genelec 7360A and 7370A subwoofers. These subwoofers are designed to integrate easily into all environments, both those using analog audio as well as those using digital AES/EBU audio. Genelec 7360A and 7370A subwoofers are designed for precise monitoring of multichannel analog audio signals and stereo AES/EBU signals. Multichannel AES/EBU signal can be monitored by using the 9301 multichannel digital audio interface device connected to the subwoofer.
Energy saving Intelligent Signal Sensing (ISS) can be turned on to put the subwoofer automatically into a standby state when audio signal has been absent for a selected time. In the standby mode the product consumes less than one Watt of power. Upon sensing an input signal the subwoofer automatically wakes up to full operation. The wait until entering the ISS power save
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.
Installation
Each subwoofer is supplied with a mains
cable, one 5 m GLM network cable, mains
cable, and an operating manual. Before connecting switch the subwoofer and
monitors o.
Connections
Seven balanced XLR input/output pairs
are available for analog signals (see Figure
1). There is a dedicated LFE In and LFE Out. The Link In and Link Out connectors can be used to for daisy-chaining multiple subwoofers with minimum cable count. In addition to these analog signal connectors, digital audio in and out connectors supporting AES/EBU format are available. The digital out connector can be used to daisy chain multiple subwoofers while digital audio is being used.
Multichannel AES/EBU signal can be monitored by using the 9301 multichannel
digital audio interface device connected to the subwoofer.
Two CAT5 (RJ45) GLM Network
connectors are available for computer
control using the Genelec Loudspeaker
Manager (GLM) software.
Bypass connector supports a ¼ in
jack switch-operated subwoofer bass
management bypass function when the xed
85 Hz subwoofer crossover is used.
The mains input supports a wide mains voltage range (100-240 VAC, 50-60 Hz) and enables the subwoofer to be plugged in anywhere globally. If the mains power is provided with a generator, inverter or certain lower-quality UPS devices, we recommend filtering of the mains power voltage harmonics and taking care that the voltage supply is stable.
Bass Management
Bass management splits the signal from each input into low and high frequency components. Signal content below the crossover frequency is reproduced by the subwoofer and signal content above the crossover frequency is reproduced by the monitors connected to the outputs of the subwoofer.
The 7360A and 7370A offer two bass management methods:
Centralized bass management
This method builds both the highpass and
the lowpass lters in the subwoofer and can
be used in all setups, with or without GLM
control. A xed 85 Hz crossover lter for the
analog main channels is default for manual use.
In this method all analog signal cables are routed through the subwoofer's IN/ OUT connectors to the respective main monitor
s.
Distributed bass management
In this method the lowpass lter is applied
in the subwoofer and the highpass lter in
the monitor, and these are set in synchrony
using the GLM control network. This method
is only available in systems where GLM is
used.
The GLM software enables adjusting the
subwoofer/monitor crossover from 50 Hz to
100 Hz when distributed bass management is used.
The distributed bass management
supports three different signal cabling
congurations:
All channels routed through the
subwoofer's IN/OUT connectors to the respective monitors.
Y-cables from the source to the subwoofer's IN connector and the monitor's signal input.
Signal sources with dual outputs for each channel.
Using With GLM™
Control Network
Subwoofers are fully compatible with
Genelec Loudspeaker Manager GLM™ and
the proprietary Genelec monitor control network and Genelec SAM monitors. Using
the GLM control method unleashes the full
room compensation power in the subwoofer, with 20 parametric room compensation
lters. This level of room compensation detail
is only available when the GLM is used. Use
with the GLM™ network is described in the
DSP System Operating Manual.
System setup
Although the subwoofer can be used without
the GLM™ software and control network,
they only reach their full potential when
set up and calibrated using the GLM™
software. Genelec Loudspeaker Manager
GLM™ and the proprietary Genelec
monitor control network offer automated acoustic equalization and alignment for any reproduction system from simple stereo to
very complex 3D immersive setups including
also one or more subwoofers. GLM setup is
fast and accurate and can precisely address the typical narrow-band low frequency mode resonances of a room. The settings can be controlled with a computer or be permanently stored in the monitors to make the setup available at all times even when a computer is not in use. Genelec recommends setting
up SAM monitoring systems using GLM. You
can nd a detailed description of the setup
and the use of GLM™ in the GLM™ System
Operating Manual.

Using Without GLM
Cabling
The 7300 series subwoofers can be easily set
up using the xed 85 Hz analogue crossover
filter. This fixed crossover filter is on as
a factory setting and highpass filters the analogue outputs on the subwoofer. When
using this method, run each signal cable rst
to the subwoofer. Then, run the respective output to the monitor. This monitor feed
signal is highpass ltered at 85 Hz.
When using the LFE signal, run the LFE
signal to the subwoofer LFE in connector.
When daisy-chaining multiple
subwoofers, run a cable from the Link Out
connector the next subwoofer’s Link In
connector. When using the LFE signal, also
Phase Difference: 270°
Phase Difference: 90°
run a cable from the LFE Out to the next
subwoofer’s LFE In.
Control Switches
BASS ROLL-OFF controls compensate for
the very low frequency boost, reducing the 20 Hz level in 4 dB steps. The settings add to a total of 12 dB attenuation. Setting both
switches to "OFF" obtains a at response.
PHASE switches can put the subwoofer in phase with a selected main monitor. Incorrect phase alignment can cause a drop in level at the crossover frequency. See chapter "Setting the Phase Switches."
Digital LFE switch selects the low pass frequency for the subframe selected to
reproduce LFE (see "LFE CHANNEL" below).
The frequencies are 85 Hz for "OFF" and 150 Hz for "ON."
LFE CHANNEL A/B selects which subframe
carries the LFE signal. "ON" for A, "OFF" for
B. If A is selected for LFE, the B subframe is
assumed to carry main channel audio.
LFE +10 dB function adds +10 dB of gain. See chapter "Using the LFE +10 dB function."
LEVEL switches scale down the subwoofer output level. The switch settings add up and combine with therotary level adjustment control.
TEST TONE switch activates the 85 Hz test tone used for calibrating the phase. See chapter "Setting the Phase Switches."
ISS switch activates the signal sensing automatic energy saving function.
STORED switch selects the settings stored inside the memory of the subwoofer and settings made by the subwoofer's controls.
The stored settings are set using the GLM
Loudspeaker Manager Software and the GLM control network and provide superior
functionality compared to subwoofer's own controls.

Power up the system and set the TEST TONE switch to "ON." Now you can hear an 85 Hz test signal from the subwoofer and the main monitor connected to the center channel output.
Setting the Phase Switches
Incorrect phase alignment between main monitors and subwoofer causes a drop in the frequency response of the whole system at the crossover frequency. Figure 3
shows the eect of phase dierence to the
frequency response.
The phase dierence between the main
monitors and subwoofer at the listening position depends on the position of the subwoofer, so the phase adjustment should be done only after the preferred position is found and subwoofer and monitor levels
have been aligned. GLM software control
adjusts the phase automatically, but if GLM
is not available, the following manual phase matching can be applied.
Manual Phase
Adjustment Method
Genelec 7360A and 7370A subwoofers are equipped with a built-in 85 Hz frequency test tone generator for phase alignment. The test tone generator is connected to the subwoofer's "TEST 1" output. Connect temporarily the monitor to this output for manual phase alignment.
1. Toggle the -180° phase switch on and o,
and set it to the position which gives the lowest sound level at the listening position.
2. Next toggle the -90° phase switch on and
o, and again set it to the position which
gives the lowest sound level.
3. Finally, set the -180° phase switch to the opposite setting and deactivate the test signal. The phase adjustment is now complete.
Using the LFE +10 dB
Function
Dolby Digital and DTS encoding formats
present the LFE channel with +10 dB gain
relative to the main channels. Surround sound decoders may automatically add +10
dB of LFE gain to restore the level balance.
The “LFE +10 dB” function can add the
+10 dB of gain to the LFE channel in the
production stage if it is not already done by the source connected to the monitoring
system. Switching the “LFE +10 dB” switch
to the “ON” position activates the function.
If the LFE output is at a 10 dB higher level
than other (non-LFE) channels, this switch
should be set to “OFF”.
The “LFE +10 dB” function should not be
used in the following cases:
• If the +10 dB LFE gain is already
implemented by another device, for
example, a surround sound processor
or the output matrix of a mixing console.
When producing an audio format
that does not require the use of +10 dB
gain on the LFE channel.
Additional Information
Positioning Subwoofer in 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 at the front wall slightly offset from the room center line. Often methodical
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 usually 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). Cancellations from the wall are then avoided.
Operating Environment
These subwoofers are designed for indoor use only. The permissible ambient temperature is 15-35 degrees Celsius (50-95°F) and relative humidity 20% to 80% (noncondensing). When the product has been stored or transported in cool environment and is taken into a warm room, wait 0.5-1 hours before opening packing to prevent condensation of humidity before connecting to mains power.
Minimum Clearances
Do not cover the grille or place the subwoofer so that there is less than 0.1 m (4 in) of free space in front of the grille.
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). Make sure that the
space under the subwoofer allows air ow.
Thick carpets may block ventilation needed
for cooling the electronics. The reex port
opening should have a clearance of at least
7.5 cm (3 in) to ensure functioning of the
reex port.
Flush Mounting
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 7.5 cm (3 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 needed for ventilation as this may cause
unwanted acoustic eects.
Maintenance
There are no user serviceable parts inside the subwoofer. Maintenance or repair must
only be done by a Genelec certied service.
Guarantee
Genelec guarantees the subwoofers for two years against manufacturing faults or defects altering performance. Refer to the reseller for full sales and guarantee terms.
Safety Considerations
The 7360A and 73700A have been designed in accordance with international safety standards. To ensure safe operation, the following warnings and precautions must be observed:
Servicing and adjustment must only be
performed by a Genelec certied service.
The subwoofer enclosure must not be
opened.
Do not use this product with a mains cable or mains outlet having no protective earth (potential equalizing) connection as doing so may result in personal injury.
• To prevent re or electric shock, do not
expose the product to water or moisture.
• Do not place objects lled with liquid, such
as vases, on the subwoofer or near it.
• The amplier is not completely
disconnected from the mains power unless the mains cable is removed from
the amplier or the mains outlet.
• Free ow of air behind and around the
