Returning to factory settings
GLM settings stored in a 9301B can be
erased by keeping the power switch
depressed for more than 10 seconds before
releasing it again. This returns the 9301B to
its factory settings. After this, GLM software
should be used to recongure the 9301B.
Operating Environment
The 9301B is designed for indoor use
only, and the permissible ambient room
temperature is 15-35 degrees Celsius (50-
95°F) with a relative humidity of 20% to 80%
(noncondensing). If the 9301B has been
stored or transported in a cool environment
before entering a warm room, please wait
between 60 minutes before unpacking it,
as this will prevent harmful condensation.
Sufficient cooling must be ensured to
keep the 9301B within optimal operating
temperatures. No minimum clearance for
ventilation is needed around the interface.
Maintenance
There are no user serviceable parts inside
the 9301B. Maintenance or repair must only
be performed by Genelec certied service
personnel.
Guarantee
Genelec guarantees the 9301B for two
years against manufacturing faults or defects
that alter performance. Refer to the reseller
for full sales and guarantee terms.
Safety Considerations
The 9301B has 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 Genelec certified service
personnel.
• The enclosure must not be opened.
• Do not use this product with a mains
cable or mains outlet without a protective
earth (potential-equalising) connection, as
doing so may result in personal injury.
• To prevent fire or electric shock, never
expose the unit to water or moisture.
• Do not place objects filled with liquid,
such as vases, on or near the 9301B.
• The 9301B is never completely
disconnected from mains power unless
the mains cable is removed from the
device or the mains outlet.
Compliance to FCC Rules
This device complies with part 15 of the
FCC Rules. Operation is subject to both of
the following two conditions:
• This device may not cause harmful
interference.
• This device must accept any interference
received, including interference that may
cause undesired operation.
Note: This equipment has been tested
and found to comply with the limits for a
Class B digital device, pursuant to part
15 of the FCC Rules. These limits are
designed to provide reasonable protection
against harmful interference in a residential
installation. This equipment generates, uses,
and can radiate radio frequency energy
and, if not installed and used in accordance
with the instructions, may cause harmful
interference to radio communications.
There is no guarantee that interference will
not occur in a particular installation. If this
equipment does cause harmful interference
to radio or television reception, which can
be determined by turning the equipment o
and on, the user is encouraged to try and
correct the interference by one or more of
the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the
equipment and receiver.
• Connect the equipment into an outlet on
a circuit dierent from that to which the
receiver is connected.
• Consult the dealer or an experienced
radio/TV technician for help.
Modications not expressly approved by the
manufacturer can void the user’s authority to
operate the equipment under FCC rules.

Setting up a 9301B in GLM:
• Select the ‘Input Signal Type’ for the
monitor Group to be ‘AES/EBU Digital’.
Then 9301B devices become active in
the group. Set the ‘AES/EBU Digital Input
Mode’ for all the connected 7300 Series
subwoofers to ‘Multichannel’.
• Select the AES/EBU inputs to enable
them.
• In the ‘LFE Channel’ drop-down, select
the AES input and subframe that carries
the LFE channel audio.
• Select the ‘+10 dB’ setting in the
subwoofer configuration if the LFE
channel audio requires a 10 dB boost
relative to the main audio channels.
When all 9301B units in the system are set to
‘Group O’ state, the ‘AES/EBU Digital Input
Mode’ in all 7300 series subwoofers switch
the AES/EBU digital stereo audio input to a
standard stereo audio input.
Acoustic calibration
To acoustically calibrate your setup, x the
measurement microphone included with
your GLM Kit onto a microphone stand
so that the microphone points upwards,
then place the microphone at the listening
position with the top positioned at the
listener’s ear height.
Follow the steps in GLM software to
calibrate your entire system. The calibration
process starts after you create a new group
preset using ‘File’ | ‘New’ menu item. An
existing group preset can be calibrated by
selecting the ‘Group Preset’ | ‘Calibrate’ meu
item.
If you wish to disconnect the computer
after calibration, save GLM calibration onto
monitors, subwoofers and 9301B interfaces
in your system. The settings can be stored
using GLM software menu item ‘Store' |
'Store the Current Group Settings’. Note
that monitors and subwoofers have a switch
that enables stored settings. This switch
must be set to ON for operating the system
with the stored settings. After removing the
GLM network cable and powering the 9301B
and monitors o and on again enables the
stored settings. We strongly recommend
using GLM software and keeping the GLM
network connected for the full exibility of
the monitoring system.
