Frequently Asked Questions - SL 30 INFINITY

How do I connect the Infinity SL 30 speakers to my amplifier?

Use speaker wire to connect the amplifier's positive and negative terminals to the corresponding binding posts on the speakers. Ensure proper polarity for best sound.

What is the recommended amplifier power for the SL 30?

Infinity recommends an amplifier with 20 to 150 watts per channel for optimal performance. Avoid underpowered amps that may cause clipping.

Can I use the SL 30 as a center speaker in a home theater setup?

The SL 30 is designed as a bookshelf speaker for stereo or surround sound. For a center channel, consider a dedicated center speaker for better dialogue clarity.

What is the impedance of the Infinity SL 30?

The nominal impedance is 8 ohms, making it compatible with most receivers and amplifiers.

How should I position the SL 30 speakers for best sound?

Place them at ear level when seated, away from walls to avoid bass boom. Angle them slightly toward the listening position for optimal imaging.

Does the SL 30 have a built-in subwoofer?

No, the SL 30 is a full-range bookshelf speaker. For deep bass, pair it with a separate subwoofer.

Can I remove the speaker grille?

Yes, the grille is removable. Gently pull it off to access the drivers. Reattach by pressing it back into place.

What type of speaker wire should I use?

Use 16-gauge or thicker speaker wire for runs up to 50 feet. Ensure the wire is properly stripped and connected securely.

Why is there no sound coming from my SL 30 speakers?

Check connections, amplifier power, and that the correct source is selected. Also verify the speaker wire is not damaged or shorted.

How do I clean the Infinity SL 30?

Wipe the cabinet with a soft, dry cloth. For the grille, use a vacuum with a brush attachment on low suction. Avoid liquids and harsh cleaners.

UNPACKING

Inspect your speakers carefully after unpacking. If they have been damaged in transit, call your dealer or the

trucking firm that delivered them, for instructions on how to file a claim.

POSITIONING FOR AUDIO

Proper positioning of the speakers within the listening room is of primary importance in order to achieve the best possible sound. Room reflections, furniture placement, heavy draperies, window reflections and so on, can influence sonic quality, balance and the stereo image. It is essential to experiment with different locations to determine which placement offers the best overall balance and imaging.

For the best stereo effect, the speakers should be placed at least 7-10 feet apart. At times, angling the speakers

slightly inward toward the listening position will add to overall spaciousness and deliver a more realistic sound stage. Try to avoid placing the speakers directly against the wall, or in corners of the room because this may sacrifice depth of image and create excessive boominess. If you must place the speakers higher than ear level, tilt them downward to direct the tweeters toward your ears. For optimum performance, bookshelf speakers should be placed either on a bookshelf, a pedestal, or wall-mounted.

POSITIONING FOR HOME THEATER

There are a number of ways to position the speakers for proper playback in a home theater installation. If the speakers are positioned properly for home theater they will be suitable for audio and video playback.

The left and right front speakers should be placed alongside the TV monitor; however, they should be at least 24" away to prevent color smearing. A center channel speaker can be placed on top of the TV monitor or placed on the floor below the TV, tilted upward toward the listener for maximum sonic impact.

A subwoofer's primary location should be on the same line with the left or right front speaker. If bass response is not adequately deep, then the subwoofer may be moved closer to a wall, or for maximum bass, moved into a corner.

The rear speakers can be placed alongside, or behind the listener's position. Final placement will depend on room acoustics, availability of space and listener's preference. Many listeners do not like having a sound source coming directly from behind. Placing the rear speakers on the

side and slightly to the rear may provide a more balanced surround sound field.

Study this drawing to help determine the placement that best suits your needs.

CONNECTING THE SYSTEM

Make sure all equipment is turned off before making connections.

Connect your power amplifier to your speakers by using heavy gauge (#16, 14 or heavier) wire with polarity coding. The side of the wire with a ridge or other coding should be considered plus (+). The speakers must be connected in phase (both woofers always moving in the same direction at the same time) and every precaution must be taken to insure proper in-phase hookup (see diagram). If the speakers are out of phase (one speaker moving outward while the other moves inward) the

result will be cancellation of bass frequencies and a floating effect preventing instruments and vocalists from stabilizing in their proper perspective.

SETTING THE AUDIO SYSTEM CONTROLS

Never operate your audio system with the equalizer, tone and loudness controls set to maximum boost. This will place undue strain on the amplifier and could also result in damage to the speakers.

The position of the volume control setting is of little consequence in judging the amount of power a system generates. Loudness is a function of audio gain, which in itself is unimportant to the user. 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 of your system completely when changing a record or switching inputs from phono or CD to FM, etc. Excessively loud transients, which can result from a dropped stylus on a record or from improperly designed switches, can result in severe damage to your speakers.

Furthermore, when changing wires, pulling plugs, etc., always turn off all the equipment to prevent transients from entering the speaker. Use caution, and your speaker will repay you with many years of trouble-free service.

ACOUSTIC FEEDBACK

If, after connecting your system you find the bass response to be boomy (or lacking in tightness and solidity) or if the bass driver cones produce excessive movement, the cause can usually be attributed to acoustic feedback – vibrations from the speakers reaching a turntable and tone arm, creating a resonance. In turn, this vibration is fed back to the electronics and speaker. Since SL Series speakers extend to very low frequencies, isolating the turntable from vibrations becomes an important procedure.

The turntable should be placed on a heavy, solid support

located as far from the speaker as possible. At times, using a shock mounted base helps reduce vibration pickup. If after trying various methods to reduce acoustic feedback the phenomenon still exists, contact your dealer for assistance.

NOTE:

CD players are also susceptible to acoustic feedback and should be mounted on solid supports to isolate them acoustically. Another method to isolate the CD player is to mount it on four rubber or plastic legs which have a predetermined amount of elasticity.

Your Infinity speaker cabinets are covered with a high quality vinyl which requires very little maintenance. Dust the enclosures with a damp cloth, or a name brand

furniture polish. The grilles may be cleaned by using a vacuum cleaner on the low power setting.

IN THE EVENT OF TROUBLE

Note that you can use your amplifier's two channels of information for simple trouble-shooting. If the sound quality is distorted, listen to each speaker separately to check if the fault is present in both. If it is, then the trouble is likely to be elsewhere in your system. If the fault is in one channel only, reverse the outputs from your amplifier to the speakers (right-to-left and left-to-right). If the distortion moves to the other channel, the fault is not in the speaker. (This technique may also be used to locate a fault between the signal source and pre-amp/receiver and/or between preamp and power amp(s). If you have been unsuccessful in locating the specific source of trouble (or if you have located it, but have been unable to correct it), make inquires in the following order.

Consult the Authorized Infinity Dealer where you purchased the system. Infinity Dealers are audio specialists and can be of great assistance.
