INTRODUCTION
Thank you for choosing Gallo Acoustics.
Please take the time to read and understand this
guide thoroughly before installing your RoomSub.
This will ensure that you achieve optimal
performance without the risk of causing damage to
your subwoofer, speakers or amplifier.
ROOMSUB FRONT ROOMSUB BACK
RUN-IN PERIOD
Your Gallo Acoustics RoomSub utilises technologies
that only reach their optimum performance levels
after a period of 20 - 40 hours of use. During this
run-in process the loudspeaker driver will loosen-up,
and your subwoofer will develop the acoustic
characteristics that are our signature.

PLACEMENT
The placement of your RoomSub subwoofer within
the room is not as critical as speaker placement, since
frequencies of 80Hz and below are non-directional. This
allows you to place the subwoofer wherever you want
in the room.
• Ensure that the PHASE control is used properly.
As a general rule, if the subwoofer is in front of the
listening position have the PHASE control at 0º.
If the subwoofer is behind the listening position,
then set the PHASE to 180º.
• Disconnecting your loudspeakers so you are only
listening to bass playback will help as you try to
find areas of the room where bass is overpowering,
or where bass is lacking.
Another tactic would be to select several positions that
will suit the aesthetics of the room, and try each
position in turn to see which position provides the best
response. The settings of the subwoofer can then be
tailored to suit the position.

CONTROLS
CROSSOVER
The CROSSOVER control is variable from 50Hz to
180Hz. In simple terms, the subwoofer will play all
frequencies below the CROSSOVER setting.
LEVEL
The LEVEL control sets the volume of the subwoofer
in relation to the main speakers. Once set, volume
will climb and decrease along with your main system
volume.
PHASE
The PHASE control allows you to adjust the phase
of the subwoofer relative to the main speakers. This
helps when positioning the subwoofer - in general, if
the subwoofer is in front of the listening position have
the PHASE set to 0º. If the subwoofer is behind the
listening position, then set the PHASE to 180º.
POWER SWITCH
Set to either OFF, AUTO or ON. When set to AUTO,
the RoomSub will automatically detect a signal from
the source amplifier and, in turn, will power up the
subwoofer. It will also return to its standby mode
automatically when the source is no longer detected.
AC SELECTOR
This should already be set to the voltage used in your
country. It can be adjusted should you wish to a use
this product in a country where a different AC voltage
is used. Please note that the internal fuse should be
changed to suit the new AC voltage.
CONNECTIONS
LINE IN/OUT
This is used to connect your RoomSub to your
amplifier using a coaxial (RCA) cable. Connect the
subwoofer pre-out or LFE (SUBWOOFER) output on
your amplifier to the LINE-IN on the subwoofer.
POWER CONNECTOR
Plug the AC power cable here, and then into a mains
supply, do this after all other connections have been made.
USB CONNECTOR
This can be used to power external equipment such
as a wireless signal receiver. The USB connector can
output a maximum of 1 amp at 5 volts.
FUSE
The fuse protects RoomSub from abnormal power
conditions. If the subwoofer fails to power, check
this fuse and only replace with the type noted below:
110-120V AC Supply - T4AL/250V fuse
220-240V AC Supply - T2AL/250V fuse

2.1 SET-UP
When using your RoomSub in a 2.1 set-up, connect as
follows :
• Run speaker cables from your amplifier to your
loudspeakers.
• If your amplifier has a dedicated subwoofer output,
then this can be used to connect your amplifier to
the subwoofer using a single coaxial (RCA) cable.
Connect to the L/LFE LINE-IN on the subwoofer.
• If your amplifier has pre-outs, then this can be used
to connect your amplifier to the subwoofer using a
set of coaxial (RCA) cables. Take care to ensure you
have the left and right connected correctly
• On the subwoofer adjust the CROSSOVER to
around 100Hz, once the system is playing music,
you can adjust this to suit your loudspeakers
performance capabilities.
• When music is playing, you can adjust the LEVEL
control to match the subwoofer and loudspeaker
volume.

MULTI-CHANNEL SET-UP
When using a multi-channel surround sound system, first
ensure that you are familiar with your amplifier’s functions
to ensure that the correct mode and settings are applied.
• Identify your AV amplifier’s SUBWOOFER or LFE output.
Connect this to the L/LFE LINE-IN on the subwoofer
using a coaxial (RCA) cable.
Please note - You can use a Y-splitter to split the signal
into both left and right LINE-IN on the subwoofer.
Alternatively, some amplifiers have two LFE (SUBWOOFER)
outputs, which allows direct connection to both LINE-IN
connectors on the subwoofer via a twin coaxial (RCA) cable.
• Make adjustments on your AV amplifier to ensure that
the correct frequency range is being distributed to your
speakers and subwoofer.
For Gallo Acoustics Micro and A’Diva loudspeakers, use a
small speaker setting on your amplifier, to protect the
loudspeakers from the lowest frequencies.
• Turn the crossover dial to its maximum, as the AV
amplifier will handle bass control and distribute the
frequencies accordingly.
• When audio is playing, adjust the LEVEL control so
the subwoofer volume matches the satellite speaker
volume.
Consult both your AV amplifier and loudspeaker owner’s
guides for more detailed set up instructions of these
components.
