Frequently Asked Questions - TSS-SUB750 INFINITY

How do I connect the TSS-SUB750 to my receiver?

Use the Line-Level (LFE) Inputs on the subwoofer. Connect a single RCA cable from your receiver's subwoofer output to either the L or R input. Set the LFE/Normal Switch to 'LFE' if your receiver has a Dolby Digital or DTS processor, or to 'Normal' if not.

What is the correct phase setting for my subwoofer?

The Phase Switch can be set to 0° or 180°. Adjust it to maximize bass output at your listening position. Experiment with both settings to determine which provides the best integration with your main speakers.

How do I adjust the crossover frequency?

Use the Crossover-Frequency Adjustment control on the rear panel. For smaller satellites, set it higher (120Hz-150Hz); for larger speakers, set it lower (50Hz-100Hz). This control is bypassed when the LFE/Normal switch is set to LFE (crossover handled by receiver).

Why is my subwoofer not turning on?

Check that the Power Switch is set to ON and the AC cord is plugged into a live outlet. The subwoofer enters Auto Standby (red LED) after 10 minutes without signal; it will power on (green LED) when a signal is detected. If still off, verify input connections.

How do I set the subwoofer level for best performance?

Start with the Subwoofer Level Control at minimum, then gradually increase while playing bass-rich content. Adjust until the bass blends seamlessly with your main speakers without overpowering them. Aim for a natural, balanced sound.

What does the LFE/Normal switch do?

The LFE/Normal Switch selects the input mode. Set to 'LFE' when using a Dolby Digital or DTS receiver/processor (the receiver handles the crossover). Set to 'Normal' when using a receiver without such processing; the subwoofer's internal crossover then becomes active.

Can I place the subwoofer in a corner?

Yes, corner placement can enhance bass output due to boundary reinforcement. However, it may cause boomy or uneven bass. Experiment with different locations, including corners and along walls, to find the smoothest response in your room.

How do I clean the subwoofer?

Use a soft, dry cloth to wipe away dust or fingerprints. Do not use any liquids or cleaning agents, as they may damage the finish or internal components.

What does the auto standby feature do?

The Auto On/Standby feature automatically switches the subwoofer to standby (red LED) after approximately 10 minutes of no audio signal to save power. It instantly powers back on (green LED) when a signal is detected. You can leave the power switch on during normal use.

What crossover setting is recommended with Infinity satellite speakers?

For Infinity Total Solutions satellites, a crossover setting of 100Hz - 120Hz is recommended. Ensure the LFE/Normal switch is set to LFE if using a Dolby Digital/DTS receiver, which will then control the crossover.

PLACEMENT

Since the installation of a subwoofer can be somewhat more complicated than installing full-range speakers, it is essential that you read this section very carefully prior to connecting the subwoofer to your system. Should you have questions relating to your installation, it is advisable to call either your dealer or Infinity's Customer Service Department for advice.

The performance of the subwoofer is directly related to its placement in the listening room and how you align the subwoofer with its satellite speakers. Setting the volume of the subwoofer in relation to the left and right speakers is also of critical importance because it is essential that the subwoofer integrate smoothly with the entire system. Setting the subwoofer's volume level too high will result in an overpowering, boomy bass. Setting the volume level too low will negate the benefits of the subwoofer.

Here are several additional facts on installation that may prove useful. It is generally believed by most audio authorities that low frequencies (below 125Hz) are nondirectional and, therefore, placement of a subwoofer within any listening room is not critical. While in theory it is true that the larger wavelengths of extremely low frequencies are basically nondirectional, the fact is that, when installing a subwoofer within the limited confines of a room, reflections, standing waves and absorptions generated within the room will strongly influence the performance of any subwoofer system. As a result, the specific location of the subwoofer becomes important, and we strongly recommend that you experiment with placement before choosing a final location.

Placement will depend upon your room and the amount and quality of bass required (for example, whether or not your room permits placement of the subwoofer near either satellite).

Before deciding where to best place your speakers, survey your room and study Figures 1 and 2.

Figure 1. In this overhead view of a typical installation, the powered subwoofer provides bass for effects and music.

A Few Suggestions

We recommend that you do not operate your speakers or subwoofer with the bass, treble and loudness controls set to full boost. This will place undue strain on your electronics and speakers and could damage them.

The volume control setting on your processor/preamp or receiver is not a specific indication of the overall loudness level of the speakers. The only important consideration is the loudness level at which the system can be played, regardless of where the volume control is set.

Always turn down the volume control setting on your processor/preamp or receiver when changing a cassette or CD, or switching inputs to AM or FM operation. Excessively loud transients (clicks or popping sounds) can damage the satellite speakers and possibly the subwoofer.

Important!

Whenever changing cables, pulling plugs, etc., ALWAYS TURN OFF ALL EQUIPMENT, including the subwoofer.

SUBWOOFER CONNECTIONS

If you have a Dolby® Digital or DTS® receiver/processor with a low-frequency-effects (LFE) or subwoofer output:

Set line-level/LFE switch to "LFE."

If your receiver/processor does not contain a Dolby Digital or DTS processor but has a subwoofer output:

Set line-level/LFE switch to "Normal."

NOTE: If your receiver/processor has only one sub out, you may use either the L or R input.

OPERATION

Surround Modes

When using the TSS-SUB750 in a Dolby Digital or DTS home theater system, make sure all speakers are set to "Small". When using the TSS-SUB750 as part of a Dolby Pro Logic* home theater system, make sure the receiver's center channel mode is set to "Normal."

Some Dolby Digital-equipped receivers/processors offer different setup options for each source or surround mode, e.g., CD-stereo, videotape, Dolby or Pro Logic. In each case, follow your equipment's instructions to ensure that the subwoofer output is turned on and that the speakers are set to "Small" in each mode.

Power On

Plug your subwoofer's AC cord into a wall outlet. Do not use the outlets on the back of the receiver.

Initially set the Subwoofer Level Control 1 to the "MIN" position.

Turn on the subwoofer by pressing the Power Switch ⑥ on the rear panel.

Turn on your entire audio system and start a CD or movie soundtrack at a moderate level.

Auto On/Standby

With the Power Switch 6 in the ON position, the LED on the front panel will remain lit in red or green to indicate the On/Standby mode of the subwoofer.

RED = STANDBY (No signal detected, amp off)

GREEN = ON (Signal detected, amp on)

The subwoofer will automatically enter the Standby mode after approximately 10 minutes when no signal is detected from your system. The subwoofer will then power on instantly when a signal is detected. During periods of normal use, the Power Switch ^6 can be left on. You may turn off the Power Switch ^6 for extended periods of nonoperation, e.g., when you are away on vacation.

Adjust Level

Turn the Subwoofer Level Control ^① up about half way. If no sound emanates from the subwoofer, check the AC-line cord and input cables. Are the connectors on the cables making proper contact? Is the AC plug connected to a "live" receptacle? Has the Power Switch ^⑥ been pressed to the "On" position? Once you have confirmed that the subwoofer is active, proceed by playing a CD or DVD. Use a selection that has ample bass information.

Set the overall volume control of the receiver/processor to a comfortable level. Adjust the Subwoofer Level Control ① until you obtain a pleasing blend of bass. Bass response should not overpower the room but rather be adjusted so there is a harmonious blend across the entire musical range. Many users have a tendency to set the subwoofer volume too loud, adhering to the belief that a subwoofer is there to produce lots of bass. This is not entirely true. A subwoofer is there to enhance bass, extending the response of the entire system so the bass can be felt as well as heard. However, overall balance must be maintained or the music will not sound natural. An experienced listener will set the volume of the subwoofer so its impact on bass response is always there but never obtrusive.

Crossover Adjustment

The Crossover Adjustment Control 4 determines the highest frequency at which the subwoofer reproduces sounds. If your main/satellite speakers can comfortably reproduce some low-frequency sounds, set this control to a lower frequency setting, between 50Hz and 100Hz. This will concentrate the subwoofer's efforts on the ultradeep bass sounds required by today's films and music. If you are using smaller speakers that do not extend to the lower bass frequencies, set the Crossover Adjustment control to a higher setting, between 120Hz and 150Hz.

NOTE: This control will have no effect if the LFE/Normal Switch ② is set to LFE. If you have a Dolby Digital or DTS receiver/processor, the Low-Pass Frequency is set by the receiver/processor. Set the LFE/Normal Switch ② on the subwoofer to LFE. Consult your owner's manual to learn how to view or change this setting. A setting of 100Hz – 120Hz is recommended when using the TSS-SUB750 with Infinity Total Solution satellites.

Phase Control

The Phase Switch ③ determines whether the subwoofer speaker's piston-like action moves in and out with the main speakers, 0°, or opposite the main speakers, 180°. Proper phase adjustment depends on several variables such as room size, subwoofer placement and listener position. Adjust the phase switch to maximize bass output at the listening position.

Final Positioning

After correctly connecting the TSS-SUB750 system and verifying that both the subwoofer and all satellite speakers are playing, it is time to optimize the system for your particular listening room. Earlier, you placed the subwoofer in its general location. Finding the exact location for optimal performance sometimes only involves moving the speakers up to a few inches in any direction. We urge you, therefore, to experiment with placement, if possible, until your speakers deliver their full potential.

MAINTENANCE AND SERVICE

The satellite and subwoofer enclosures may be cleaned using a soft cloth to remove fingerprints or to wipe off dust.

All wiring connections should be inspected and cleaned or remade periodically. The frequency of maintenance depends on the metals involved in the connections, atmospheric conditions, and other factors, but once per year is the minimum.

If a problem occurs, make sure that all connections are properly made and clean. If a problem exists in one loudspeaker, reverse the connection wires to the left and right system. If the problem remains in the same speaker, then the fault is with the loudspeaker. If the problem appears in the opposite speaker, the cause is in another component or cable. In the event that your TSS-SUB750 ever needs service, contact your local Infinity dealer or Infinity directly at 1.516.674.4INF (USA only) or www.infinitysystems.com for a service center near you.
