A single source selector (ISM models) accepts input from one audio source (receiver/amplifier) and distributes audio output to a number of zones or speakers. However, a dual source selector (DSSM, VSS models) accepts inputs from two separate amplifiers/receivers and allows the user to select the program from one of the two sources for each zone output. With dual source selectors, the audio programs from both amplifiers cannot be selected at the same time for any zone output.

Single power source modules needs just one 3 - 5V power supply for the entire module. The module contains an inverter that supplies the operating voltage for driving the liquid crystal. Dual power source modules need a 3- 5V power supply for the LCM and another power supply to provide the Vop for the liquid crystal.

There are two main differences. The first is that dual-room/dual-source receivers allow you to send signals from different sources to each room. For example, you can enjoy home theater thrills from a DVD in your main listening room while a housemate listens to a favorite CD in the second room. Note that these receivers can only send stereo signals to the second room, not multichannel home theater sound.

In a dual-hose Venturi Series dry ice blasting system, an ejector type nozzle, similar to a conventional abrasive media blasting nozzle, is used to combine the compressed air stream with the dry ice particle carrying vacuum stream created by the ejector. In Cold Jet's single-hose Radial Feed Series dry ice blasting systems, the dry ice pellets are mechanically fed into the air stream. No energy is wasted creating a vacuum to pull the pellets through a separate line.

Size. Dual Layered Disc are Twice the size of a Single Layered Disc. Dual layered disc's also cost more.

Yes you can, but it is not recommended unless the amplifier can operate at the lower impedance that will result from the increased number of zones. If impedance-matching volume controls are used, that will increase the number zones you can use while maintaining an acceptable system impedance.

Depending on each application, either single-rate or dual-rate springs are available. Dual-rate springs are just that-- a spring set with two separate rates. This is done with a short spring stacked on a longer spring. As both springs collapse they result in a soft, or initial, rate. The spring set will retain this initial rate until the short spring stops compressing. At that point, the spring rate "crosses over" to the stiffer, or final, rate.

It is easy to confuse a dual voice coil sub as a better subwoofer, but that’s not the case. You will get the same output from either sub when used in the right application. Both sets of terminals must be wired up when using a dual voice coil subwoofer. Your amp and the number of subs will determine which subwoofer you would want. For example, if you had a TA5601 amplifier and wanted to run a pair of 12s, you would want single voice coil 4Ω woofers.

The difference between dual track and single track is that single track holders hold one line of tags while dual track holds two lines of tags. Click here to view E-Z tags and holders.

Answer: Acquinox? dual flush toilets will save you over 6,000 gallons of water per year for a family of 4. The Dual Flush system gives you the best of both worlds: The Low Flush uses less than 8/10s of a gallon of water while the Normal Single Flush uses 1.58 gallons ? still within conservation limits.

ALSO SEE THE SUPPORT SECTION FOR A TUTORIAL REGARDING SINGLE AND DUAL CONVERSION. The single conversion receiver uses a single Local Oscillator at 455 kHz removed from the transmitter frequency to achieve narrow band and high sensitivity. A dual conversion receiver has two local oscillators. The first L.O. is 10.7 MHz removed from the transmitter frequency to overcome the one weakness of single conversion; i.e., the lack of rejection at the image frequency.

Working Assets Wireless customers enjoy the best wireless coverage available through Sprint, providing the largest all-digital, all-PCS nationwide network. The network covers more than 4,000 metropolitan areas and communities across the country. Digital technology allows your call to be processed and carried on the network more efficiently than an analog network. Digital technology also ensures greater call security than analog technology.

A booster is a radio frequency amplifier that will do two things: it will take the signal that is transmitted by the cell phone when a call is engaged and use electrical energy to make it stronger and send it out through the antenna to the tower. The booster will also receive the signal that was generated by the tower, through the booster antenna, use electrical energy to amplify the tower signal and send it to the phone.

AIRLUX portable air conditioners have only one air exhaust hose as oppose to some other models that have two air hoses, one for air intake and one for air exhaust. A single hose unit will take air from the room that it is in and return most of that air back into the room as cold conditioned air. A dual hose unit works by taking in air from the outside through one of its hoses and using that air to cool the unit - and then that hot air is expelled through the exhaust hose.

The single-action clamp is a one piece assembly - both the clamp and the base are attached to the turntable. Unfortunately, the brake of the single-action clamp wears out with frequent use, requiring regular maintenance. In 1990, the Wilson Sporting Goods Co. introduced its Pro Staff (Prestige) stringing machine, which was manufactured in Taiwan. It utilized the single-action swivel clamp assembly, and it had brake problems (as mentioned above). Wilson Sporting Good Co.

Model S1201 is a Dual Module Speaker. It has 2 speakers built into a durable acoustically -carpeted cabinet with built-in handle & tripod mount.

Speech recognition is concerned with WHAT is being said; the system listens to the words that are spoken by the user and acts upon the spoken command by giving the user the option requested. Speaker verification which is concerned with WHO said it. The system listens to how the user speaks, and decides whether the user is who he or she claims to be. The voice engine used by MEK is language and vocabulary independent.

Many people prefer to subscribe to this list in "digest" form. This means that all of a day's messages are combined in a single email message with a table of contents. Due to network traffic and other factors, digests aren't received at the same time each day or even at the same time by all subscribers. It's not unusual for digest posts to be separated by more than or less than 24 hours. Occasionally, two digests may arrive on the same day.

One distributed with the Perl/Tk code kit itself is called FileSelect.pm and was written by Frederick L. Wagner - (based on an original by Klaus Lichtenwalder). Another module called SelFile.pm was adapted by Alan Louis Scheinine from Wagner's FileSelect.pm. It is available from: http://sun20.ccd.bnl.gov/~ptk/archive/ptk.1995.11/0122.html or http://w4.lns.cornell.edu/~pvhp/ptk/etc/SelFile.pm A module called FileSave.pm allows one to type in a new (non-existant) filename for "Save as..

To compensate for low impedance that results from connecting multiple pairs of speakers to the selector box. The protection circuit adds 5 ohms to each channel to guarantee a final load impedance that will be greater than 5 ohms at the amplifier. If impedance-matching volume controls are used in the system, the protection circuit should be set to the “off” position, since the volume controls will be configured to provide low impedance compensation.

The single-side foil is great for acoustic applications where sound can be absorbed into the natural fibers. The dual-sided foil provides an excellent radiant heat barrier to resist heat flow.

DVI has the ability to employ two links. Each link is comprised of three data channels for RGB. Each link has a maximum bandwidth of 165 MHz. Dual link has a maximum bandwidth of 330 MHz. Dual link supports resolutions up to 2048 x 1536. Currently, most equipment is Single Link.

If a child is dually enrolled, s/he may participate in all academic and extracurricular activities offered at the district on the same basis as a regularly enrolled child. A child enrolled in a HSAP must also dually enroll to participate in academic and extracurricular activities.

the ohm load is the total resistance that your amp is seeing when wired up to the subs/speakers. In general, lower ohm loads will mean that your amp will be putting out more power. However, you need to make sure that your amp is stable at that ohm load or you will cause significant damage. The ohm load can be changed by wiring the subs differently, ie. Parallel vs. series. To determine ohm load when wired in series, the ohm load = Resistance1 +Resistance2+Resistance3+....

Talkman uses speaker-dependent voice technology. Speaker-dependent systems require each user to "train" the system for his or her individual speech pattern, dialect, or language. Voice training takes only ten to fifteen minutes per Talkman user. Training allows the system to be much more accurate and robust in an industrial environment where there is a wide range of accents, dialects, and languages, and much extraneous noise.

In voice verification, a subject’s identity is confirmed by matching his or her voice against a single voiceprint. This is typically done when there is some information provided to indicate the subject’s identity, such as an account number, and the voiceprint matching is done for confirmation. Spike Server operates in voice verification mode. In speaker identification, the subject’s voiceprint is matched against several voiceprints.

Speaker selectors are rated at 70-100 watts per channel (with circuit protection engaged). If the power handling is exceeded, the selector/switcher can overheat and cause internal components to burn. noted in the previous section, a speaker selector's maximum power handling is reduced with the circuit protection switch in the “on” position. If impedance-matching volume controls are also used in the system, the circuit protection should be turned “off.

You can complete a dual major (more than one course of study) by completing the requirements for each major. At graduation time, you will have both majors listed on one diploma (example: Bachelor of Arts, Communication and Sociology). Please note that if you are completing a Bachelor of Science degree and a Bachelor of Arts degree, you may only complete this as a dual baccalaureate degree.
