INTRODUCTION

Thank you for choosing Gallo Acoustics.
Please take the time to read and understand this guide thoroughly before installing your subwoofer. This will ensure that you achieve optimal performance without the risk of causing damage to your subwoofer, speakers, or amplifier.

RUN-IN PERIOD

Your Gallo Acoustics subwoofer utilizes proprietary technologies that only reach their optimum performance levels after a period of 60 – 80 hours of use. During this run-in process the loudspeaker driver will loosen up, the patented S2 fill material will settle, and your loudspeakers will develop the acoustic characteristics that are our signature.

ABOUT YOUR SUBWOOFER

Your TR-3D subwoofer uses many proprietary technologies to ensure the absolute best performance can be delivered. These contribute to an enhanced level of bass output, precision bass reproduction, and dynamic range not found in other subwoofers of similar price and size. Gallo Acoustics’ S2 technology is a simple yet powerful approach to enhancing low-frequency extension, whilst neutralizing internal resonance. This results in the woofer behaving as if it were in a larger enclosure, allowing deeper and more powerful bass than it ordinarily would produce. This technology can also be found in all Gallo Acoustics loudspeakers and is precisely the innovation that allows Gallo Acoustics loudspeakers to deliver surprisingly full-range sound from compact enclosures.

PLACEMENT

The placement of your TR-3D subwoofer within the room is not as critical as speaker placement, since frequencies of 80Hz and below are non-directional. However, there are several things you can do to help you achieve the best performance from your subwoofer.

• 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.
• The best performance is usually achieved by placing the subwoofer between your front speakers and facing the listening position.
• Placing near a rear wall will aid the bass response, however, avoid corner positioning if possible as this will result in uneven bass response throughout the room.
• Disconnecting your loudspeakers so you are only listening to bass playback will help as you try to find areas of the room where the bass is overpowering, or where the 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 AND CONNECTIONS

CONNECTIONS

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, the 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.
BASS BOOST
Allows for more convenient bass equalization, and increases bass volume in relation to the main speakers without adjusting any other controls.
POWER SWITCH
Set to either OFF or AUTO ON. When set to AUTO ON, the TR-3D 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 be preset to your country of use. However, you can adjust this if you move to a country where a different AC voltage is used. Note that you will also have to change the internal fuse to suit the AC voltage.
BYPASS/CROSSOVER
Activates the subwoofer’s built-in bass management or bypasses it. If your amplifier has bass control, like an AV receiver, then set to BYPASS, otherwise set to CROSSOVER.
HIGH LEVEL IN/OUT
The HIGH LEVEL IN is used to connect your amplifier to your subwoofer using speaker cables. You can then connect a pair of speakers to the HIGH LEVEL OUT. This will also activate the subwoofer’s built-in crossover, and protect the speakers from the lowest frequencies.
LINE IN/OUT
This is used to connect your TR-3D to your amplifier using a coaxial (RCA) cable. Connect the pre-out or LFE (SUBWOOFER) output on your amplifier to the LINE IN on the subwoofer. If required, you can connect the LINE OUT to your power amplifier.
POWER CONNECTOR
Plug the AC power cable here, and then into a mains supply, do this after all other connections have been made. Ensure that the AC SELECTOR is preset to the correct position for your country.
FUSE
The fuse protects the TR-3D subwoofer from abnormal power conditions. It’s located under a small cover in the subwoofer AC power socket. If the subwoofer fails to power, check this fuse and only replace with the types noted below :
115V AC Supply – T5A 250V fuse
230V AC Supply – T2.5A 250V fu|
2.1 SET UP
There are two options for connecting the subwoofer in a 2.1 system – either using the HIGH LEVEL IN or the LINE IN. The style of speakers and amplifier you are using will dictate which method of connection you will use.

When using Gallo Acoustics Micro or A’Diva speakers, or similar compact loudspeakers, use the following method. This will run the subwoofer and protect your speakers from the lowest frequencies – ensure your subwoofer is set to CROSSOVER mode.

• Using speaker cables, connect the speaker outputs on your stereo amplifier to the HIGH LEVEL IN on the subwoofer.
• Run the second set of speaker cables from the HIGH LEVEL OUT on the subwoofer to your loudspeakers.
• Adjust the subwoofer’s CROSSOVER to around 100Hz.  When music is playing, you can adjust the LEVEL control to match the subwoofer and loudspeaker volume.

If your speakers can handle a full-range signal, like our Strada 2 speakers, then you may wish to connect the subwoofer as follows. Ensure the subwoofer is set to CROSSOVER mode.

• Run speaker cables from your amplifier to your loudspeakers.
• If your amplifier has a pre-out, then this can be used to connect your amplifier to the subwoofer using a coaxial (RCA) cable.
• If there is no pre-out, then you can run a second set of speaker cables from your amplifier to the HIGH LEVEL IN of your subwoofer.
• 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 left 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 lines IN connectors on the subwoofer via a twin coaxial (RCA) cable.

• Make adjustments to your AV amplifier to ensure that the correct frequency range is being distributed to your satellite 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.

• Switch the subwoofer into BYPASS mode, as the AV amplifier will handle bass control and distribute the frequencies accordingly.
• When music or a film 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 setup instructions of these components.
