Infinity 475a Features

Class D Subwoofer Amps
Efficiency is the benefit of the Infinity Reference Series Class D subwoofer amplifiers. A higher percentage of the power the amp extracts from the car’s charging system is converted into output to the speakers, and less is wasted as heat. That is really important if you’re trying to provide power to a 1000-watt amplifier. Class D technology turns the analog input signal into a series of pulses that can be amplified more efficiently by transistors used as switches, rather than valves. They’re either on and operating at their most efficient level, or they’re off. The pulses are converted back into an analog signal by an output filter.

CEA-2006-Compliant
All Infinity amplifiers are tested in accordance with CEA-2006, which provides a testing procedure to help customers compare amplifiers accurately–apples to apples. Specs are based on industry-accepted standards, rather than on the whims of amplifier companies’ marketing departments. Look for the CEA-2006 logo when comparing amplifiers, to be sure you’re getting the power you’re paying for.

Audiophile-Quality Full-Range Amplifiers
Class AB full-range amplifiers offer audiophile quality performance and the best compromise between efficiency, low distortion, maximum available headroom and output power.

Amps That Don’t Break
Infinity amplifiers are tested according to the strictest and most demanding reliability-testing regimen ever designed for car audio amplifiers. They are shaken, baked, frozen, dropped and shocked–all while they’re operating. When they’ve passed all these tests, they are tested again. The result is a series of amplifiers that just don’t break.

DBO Bass-Optimization Circuit
provides superior control and adjustability, compared to traditional bass-boost. DBO is a 2nd order high-pass filter that can be adjusted between 20Hz and 80Hz. The boost (or Q) adjustment boosts the signal above the highpass filter frequency. Used with a sealed box, it can help to increase output for more “fun” if it’s set to about 45Hz. If it’s used with a vented box, it should be set at or slightly below the tuned frequency of the box. That will prevent woofer unloading, and provide more output at the frequency where the box is tuned and the woofer’s excursion is minimized–where it can handle more power.

Onboard Electronic Crossovers
Reference Series amplifiers include 2nd order (12dB/octave) slopes and are continuously variable from 32Hz to 200Hz.

Variable Bass-Boost
Provides up to 12dB of boost at 50Hz in the Reference Series full-range amplifiers.

Direct-Connect Terminals
Eliminate the need for additional solder-on or crimp-on terminals and provide an easy and reliable connection for power, ground and speaker wires.

Full-Range Preamp Outputs
Eliminates the need for signal splitters.

Wireless Headphones for TV Listening: Comparing TV Ears & the TV Listener J3

Posted: 08 Jun 2011 04:58 AM PDT

Wireless Headphones for TV Listening: Comparing TV Ears & the TV Listener J3

There are many reasons that we might need to purchase a set of wireless headphones. One of us may be starting to lose our hearing & “arguing over the TV volume” is no way to spend an evening. Or, we want to watch TV in bed, but don’t want to disturb our spouse who needs to get up early the next morning. Whatever the reason, both the TV Ears & the TV Listener J3 passed the quality test.

But, here are 10 things to consider when choosing which wireless headphones are the right choice for you:

Price: When choosing electronics, we want to get the best quality possible without breaking the bank. Both of these models retail reasonably for under 0, but the Unisar TV Listener is slightly more affordable with a suggested retail of .99.

Infrared Signal vs RF Signal: Other wireless headphones that utilize a radio frequency signal provide the advantage of being able to listen from another room. The only problem is that most of the other devices in your home (stereo, microwave, wireless phones) may use the same signal and will usually cause a great deal of interference, causing static or buzzing.

Both the TV Listener J3 & the TV Ears models utilize infrared technology, the same as your remote control. With infrared, there is no interference from other sources. This will provide a much cleaner & crisper sound. Obviously, this does not allow you to travel into different rooms to listen. So, you will need to be within site of the receiver plugged into the device (TV, computer, radio, etc.)

Coverage: The range of clear reception for both the TV Listener J3 & the TV are approximately the same. Each will cover 600 square feet (or a 30-foot x 20-foot room). This should be adequate, since most living rooms are around 300 square feet. If you do need a larger coverage area, TV Ears offers a Professional Series model that retails for 0.

Independence: Some wireless headphones give you the option of only listening with or without the headphones. That’s not a problem, if it’s only you in the room. If you’ll never need to share the TV with anyone else, models such as these can usually be found for or so.

Both the TV Listener J3 & the TV Ears, however, allow you to listen to the TV independently. Your spouse and/or kids can watch at one volume and you can control your own volume independently with the headphones.

Will It Work With My TV: The biggest concern when considering wireless headphones is compatibility with new TV technologies. Both will work with any TV, computer or audio device, including Digital, Plasma or 3D televisions. As long as your device has an audio output, both of these wireless headphones are compatible and can be set up in minutes.

Hearing Aids: Here is one difference between the two. The TV Listener J3 model uses an “over-the-ear” cushioned headphone, as opposed to an “in-the-ear” headphone. This feature makes the TV Listener compatible to use WITH hearing aids. TV Ears, on the other hand though, does boast a higher decibel level for those with hearing difficulties, but because of the budded ear pieces the hearing aid needs to be removed.

Battery Life: Both the TV Listener J3 & the TV Ears operate with a re-chargeable headset that lasts approximately 15 hours when fully charged. And re-charging is easy. Just connect to the receiver when not in use & you shouldn’t have to worry about either batteries running low.

Extra Headsets Available: Both offer additional headsets that can operate on the same receiver & operate independently of the other. The TV Listener J3 extra headset retails for .99, whereas TV Ears offers additional headsets starting at .99.

Warranty: Both models offer a 90-day full manufacturer’s warranty.

How to Link Your Mp3 Player to Your Car Stereo System a review of Home Theater by :

How to Link Your Mp3 Player to Your Car Stereo System

You are going to uncover four typical selections for successfully connecting your Mp3 player to your auto stereo. I will checklist all of them here in optimal buy by way of better to most detrimental these terms of setup in addition to top quality.

Before knowing how to build custom speaker boxes for your car, here is a brief idea about car speaker boxes and their types. The type of bass you receive from your car audio system doesn’t solely depend on the speaker. For optimum speaker performance, you require strong and tightly built speaker boxes. Speakers without speaker boxes or enclosures are unable to deliver full bass, as the sound from the back of the speaker cancels some of the low frequencies emerging from the front of the speaker.

1. Nearly all more recent automobile stereos have a AUX in jack on the entrance from the stereo program unit. An AUX inside are going to be a hole concerning the encounter of the stereo that matches how large the earphone jack port for the Mp3 player. You’ll should connect your own Mp3 player for this AUX in hole with a stereo 1/8″ cable. You’ll be able to do a search for these upon Auction internet web sites along with locate them for much less than . Should you be a bit extra impatient, then you may locate them at the nearby Stereo Shack or Fry’s Consumer electronics for not a great deal a lot more. Merely connect the wire out of the Mp3 player and towards the AUX within port on the automobile stereo program, choose AUX as your personal enter gadget (other choices will likely be Compact disc player, FM, ‘m, and so on.), right after which change your own Mp3 player on. This technique will not power your Audio participant, therefore possibly expense up great or even have a charge inside your vehicle which will adjust into the smoke outlet. (some high finish Car Stereo System may connect with Apple’s IPod device and permit you to search your own song collection on the stereo program rather than on iPod and iPhone)

2. A distinct approach to connect the iPod is going to be on partial older systems which have stereo program AUX within RCA upon the rear of the unit. RCA is genuinely a link that looks like the audio allowing you to connect your TV sound and it can be commonly signified by a cable along with 2 finishes, 1 white and a thing red. So that it is possible to effectively connect your Mp3 player to this scenario, you might must invest in a stereo 1/8″ so as to Man RCA cord at your local Radio Shack. Pull the actual stereo program from the console. Hook the white and red RCA ends making use of their corresponding woman RCA ends on the back of the stereo system after which wrap the actual cord out of an additional socket to the side from the console towards the place you commonly keep the IPod. Plug the actual 1/8″ inch side of the wire into your personal IPod, power this upon, and that’s it.

Apply glue on to the outer region of the box and the back of the carpet and then enclose the carpet tightly onto the box. With the help of the razor blade, cut vertical, horizontal and angled lines in a star design into the carpet that covers the connector holes for the speakers.

3. I selection for Audio play by way of your stereo program would be to use the actual FM airwaves. These folks marketplace FM transmitters at most bulk vendor shops such as Target & Wal-Mart, as well as online retailers. Decent FM transmitters operate in the -35 range. The way these types of tasks are by insert the provided 1/8th wire to the earphone jack concerning the Mp3 player. Then on the Car FM transmitter you can pick a FM funnel. Tune your own stereo program into the corresponding FM funnel and also you should be able to listen to your MP3′s by means of the airwaves. This procedure requires power for the transmitter to operate. If you are lucky along with have a couple of extra dollars, you’ll be able to invest in a battery charger which powers both your IPod and FM transmitter. Some FM transmitters possess electric battery choices for power too. This approach is actually capable to have sound dropouts should you drive genuinely much in addition to r / c alter. It’s best to pick a train station that is not being used with regard to broadcast.

4. The last excellent option for hearing your personal Mp3s is by employing a Mp3 Outdoor patio. These persons create a mp3 adapter by having an 1/8″ wire appearing out of it that you simply plug in to your own Mp3 player. Stick the actual mp3 in your stereo program mp3 outdoor patio and the opposite finish for the participant and also pay attention to your tunes flow. My only extreme caution with this particular option is actually that a great deal of these kinds of products seem to truly go to town the actual tape deck making each device useless. Consider yourself warned.

Best of luck and enjoy the music!

An Upgraded On Wireless Surround System a review of Home Theater by :

Posted: 07 Jun 2011 11:43 PM PDT

An Upgraded On Wireless Surround System

A wireless surround system with excellent quality becomes what people are looking for. It is because sound is the most significant element of home theatre system, besides the picture or image. A good quality television is not enough to build a cinema-like home theatre, without a wireless surround speaker. To gain a more realistic experience of watching a movie in your personal entertainment system, sound and image must be collaborated well. It seems that everyone knows the principle.

Then, what’s new on wireless home theatre? Wireless and active surround sound system with built-in decoders come to be the best selling product. The leading manufacturers from Hong Kong and mainland China compete with each other in upgrading wireless of 5.1, 6.1, and 7.1 surround systems. To see the progress of this technology, check the following info.

Today, wireless sound speaker is designed with 2.4GHz RF combined with Bluetooth integration and digital amplification systems. The excellence of this upgraded technology is that you will find no line level signal wires to run. Also, with this features, a great freedom of speaker will fill all over the listening room and home. Then we include the challenges to the format within the following:

The actual signal quality of 2.4GHz RF and Bluetooth systems. It means that the Bluetooth features a practical data transfer rate of 433kbps even though it utilizes asymmetrical transfers with increasable rate. The Dolby Digital needs 400 kbps and DTS uses up to 448kbps – for a full 5.1 stream.
Digital amplification quality for surround channels. The Class-D amplification apparently becomes the currently favored amplification for wireless surround speaker.
Wireless speaker needs power. The format can exchange one inconvenience (speaker cables) for another (running power to surround speakers.) Also, it is suggested that you place power to a surround speaker, instead of a line level or speaker level cable which needs to originate from the opposite side of the listening room.

There is a prediction in Hong Kong market that by the first half-year wireless surround speaker becomes a mass production. It will grow as the demand of this sound system is increasing.

For further information, although IR models are less utilized because they are not as user-friendly like their RF counterparts, either 2.4GHz RF or IR technology is still used in current version of sound speaker system. When an obstacle happens between the IR transmitter and the receiver, the transmission will get terminated. Furthermore, to transmit the info to the sound system, we have to utilize MIR (1.15 Mbps) or FIR (4Mbps). The 5.1 surround speaker systems combined with wireless 2.4GHz rear speakers will be launched firstly.

One last thing we would say, this technology will not take more cost that you will be interested in to have wireless surround speaker featuring this technology. Indeed, technology is advanced to ease people’s life. So, enjoy watching movie like in cinema only by sitting in your entertainment area with your personal home theatre, especially with excellent wireless surround system.

If you are interested in purchasing a set of home theatre system, you probably need some info within articles on wireless surround system and cheap surround sound. By those articles you may take consideration on best device you are wishing to buy.
