For Business - The PAS and PAS II are highly awarded ultra-portable audio systems designed for mobile sales presenters, public speakers, educators and trainers. Their dual purpose labels them the only ultra-portable stereo P.A. in the world. The speaker features high quality stereo imaging and high speech intelligibility which allows our customers to do what every presenter dreams of, i.e., provide high quality sound AND voice support in a small package that weighs under three pounds.

For Entertainment - The PAS and PAS II can be used as ultra-portable personal sound systems for portable CD players, iPODS, notebook computers, PDAs and other sound equipment. The PAS design dramatically improves normal stereo, surround sound, digital audio and 3-D sound.

For Business - PAS creates the largest "sweet spot" of any presentation audio system. Therefore, everyone in the room hears the same high level of speech intelligibility no matter where they are seated and no matter what their relationship is to the location of the speakers. And, it is loud enough for presentations to an audience of 100 people.

For Entertainment - Since conventional speaker performance is drastically altered as either a presenter or a listener change position in a room, the PAS was invented to eliminate this problem. You do not have to be sitting in front of the PAS equipment to hear its high quality sound. Instead, the listener is free to move about the room without loss of sound quality. The PAS increases the multi-media enjoyment of digital audio sources available from CD players, the Internet, DVDs, iPODs, digital cable television, and digital satellite receivers. The PAS can also replace the low-quality speakers in computers, televisions, boom boxes, and portable radios without using a significant amount of space.

It is different for many reasons including its omni-directional stereo sound and attractive style, but mostly because the PAS equipment uses Mediaphile's AV Group "Listening" technology and patent. The PAS equipment is also lightweight and portable and delivers home theatre quality sound. The PAS equipment is 1/2 the price of similarly performing systems and plays as loud as equipment that requires 4 times as much power.

It weighs less than two pounds when using the satellite speakers alone, under ten pounds when using the "smart connect" subwoofer. The PAS satellites come with either of two convenient carrying cases and the CRS-3 stroller is designed to carry the three-piece system in an airline-approved stroller.

In addition, the CRS-3 stroller is designed so that the subwoofer stays inside while making your presentation and the convenient extra pockets store your extra cables, CD's and gear. The top pocket is even large enough for the new ultra portable three-pound projectors!

Each PAS speaker is about the size of an apple. A complete stereo system with its power supply will fit easily into the Small Carry Bag (UN-01) with room to spare. The UN-01 bag is about the size of a small lunch box.

For exact size and weight information, please see our specifications page under each product listing.

Designed to work perfectly with the PAS equipment, the CVS16 is also extremely powerful, yet compact and portable. Both transmitter and receiver would fit inside a shirt pocket.

Exceptional. You won't find anything in as small a package that sounds this good! And remember, the PAS equipment is omni-directional in the high frequencies.

The satellite speakers have a range of 200Hz - 17kHz. Use the smart connect subwoofer and the range is 45Hz - 17kHz.

For exact frequency response characteristics, please feel free to our downloadable specifications sheets which can be found in the Product Literature section.

The PAS equipment is compatible with notebook & PC computers, line level microphones, LCD projectors, CD players, DVD players, boom boxes, VCR's and TV's.

The PAS equipment plugs into anything that has a headphone jack.

It also comes with a mobility kit containing adapters for microphones and RCA outputs.

The PAS equipment faithfully reproduces the sound of your voice when used to make presentations. More importantly, everyone in the room hears the same thing regardless of where they are seated. Every person understands what you are saying because of its omni-directional intelligibility.

For music, there is very little difference between the sound of a live performance and the sound of a recorded performance.

Your audience will appreciate hearing, many of them for the first time, home theater quality sound from your sound clips.

DVD recordings and digital sound are awesome because the PAS equipment is true three-dimensional sound. It is the very definition of surround sound.

It makes the whole system twice as loud for those larger groups of people.Plus, during the last few years several new sources of high quality CD stereo audio have become available. The DVD and CD-R's, Internet, and digital cable, satellite, and soon digital broadcast television all make the listening experience much more enjoyable if you can hear the full range of sound available from these sources. It makes the sound so much more life-like and animated.

Almost all consumer sound systems now include subwoofers for this reason. Digital quality sound is becoming more and more common as an important ingredient in professional presentations.

The PAS equipment is pre-wired for ease of use. Just plug the power cord into a wall outlet and fit the easy signal input wire into any headphone or RCA jack and you are finished.

This new patented audio technology has received patent # 08-705-671.

The PAS equipment uses the table surface as a sound magnifier. This increases the efficiency of the audio system and allows it to play as loud as conventional systems much larger in size.

In fact, the PAS equipment will play as loud as other audio equipment four times it size and power rating.

They are round because the shape is an important part of its omni-directional technology.

Another way of thinking about this is to consider the much touted Dolby Digital or 5.1 surround sound method. By comparison, Mediaphile is "Infinity.1".

Another significant advantage to the shape of our PAS speakers is that we can make them in so many pleasant designs. For instance, magazines have described them as follows:

     The PASI shape has been called the "globe", "mushroom", "Euro", and "Japanese Tea Lantern".

     The PASII shape has been called the "Scandinavian", "hockey puck", "Minnesota Snow Flake", and a few other things.

In addition, all PAS audio equipment is more stylish than common box-shape speakers. The performance is unaffected by the shape, so look for more designs in this series in the near future.

The magazine reviews and awards that the PAS equipment has won both cite the dual functionality as a major attribute. No matter what the shape of the room, the PAS equipment functions equally well as a multimedia or voice support system.

It works best in rooms of less than 1000 square feet (approx. 30 x 30) in size and for audiences up to 100 people. However, even in larger rooms, if the listeners are within 35 feet of the PAS satellite speakers, it works great.

It is perfect for use in conference and meeting rooms and for general home and business entertainment.

STEREO - The PAS equipment is available as a stereo multimedia system because for many presentations music is very important. For instance we have customers who are performing artists using our equipment to sell their songs to record companies.

Because the PAS equipment produces true surround sound, there isn't a better "home theater" quality sound system available in this price range, especially not one that is portable.

The music reproduction quality of the PAS three piece system is unbeaten in this price range. The optional subwoofer has a "Smart Connect" design with an auto-detecting Linkwitz-Riley crossover network. It simply sounds better than anything else!

MONAURAL - On the other hand, many of our customers do not care about playing recorded music at anytime during their presentations and prefer to carry only the bare necessities with them. For these "voice-only" presenters the Ensémble Portable Presentation Companion is a better choice.

The Ensémble Portable Presentation Companion has additional functionality for this type of presenter. One, the Ensemble comes with a built in mixer so up to three sources of sound can be simultaneously connected. This eliminates the problem of having to carry even more equipment like cables and mixer boxes to accomplish the same thing. Therefore, in a single convenient one pound package, the presenter can connect up to three devices including microphones, VCRs, DVDs, and notebook computers. Plus, it doesn't matter whether the device is monaural like a microphone, or stereo like a DVD, the built-in mixer auto detects which it is and properly combines the signals.

Even the monaural mode produces wall-to-wall sound so everyone hears and understands the presenter clearly.

Cetacea Sound Corp, is a new and innovative audio design and manufacturing company located in Minneapolis, Minnesota.

Cetacea Sound Corp holds several audio patents and both designs its own products as well as consults with others to create cutting edge audio solutions that solve specific acoustic problems for its customers.

Acoustic feedback is a phenomenon that can occur in all microphone and speaker systems. It is caused by the sound from the audio speaker reaching the microphone at a volume higher than the ambient room noise and/or higher than the person's voice speaking into the microphone.

This occurs in one of two ways: 1) the audio speaker volume is too high for the room and therefore the speaker sound is reflecting off of the walls and returning to the microphone; and/or 2) the microphone has been inadvertently turned toward the audio speaker so that it is picking up the speaker sound directly thus making it louder than the voice.

Wireless microphones are more prone to feedback than wired microphones. This is because with a wireless microphone, the presenter has more freedom of movement about the room and may step too close to the audio speakers. Feedback may also occur if the volume is too high or the presenter steps too close to the walls of the room.
This is not a design flaw of wireless microphones. Most presenters prefer the freedom of movement, light weight, compact carrying size, simplicity of use, and other benefits they offer.

The PAS and Ensemble Presentation Audio Systems and the CVS Wireless Microphone Systems are less prone to feedback than other solutions. Our patented Group Listening Technology makes it easy to control.

If you experience feedback, here is how to fix it.

Solutions:

1. Rehearse your presentation. Set up the system you intend to use before hand. Test how loud you can turn the system up without creating feedback. Having an assistant adjust the volume while you are standing in the location where most of your presentation will be made is helpful. Once you establish how loud the system can be turned up, turn the volume down by another 10 - 20 %. Remember, once people enter the room and become seated, the sound system will not sound as loud as it did when you set it up. This is OK and normal.

2. The PAS Designs. The sound systems are designed such that you can walk close to it and still not create feedback. However, if you sit down in front of the speaker or bend over (thus pointing the lapel microphone at the audio speaker), it will create feedback for the reasons stated above.

3. Rehearse, rehearse, rehearse. During your rehearsal be sure to walk everywhere in the room where you may be standing during your presentation to eliminate potential hot spots caused by electrical interference and any acoustic aberrations that may create feedback. Once you know where these locations are they can be avoided.

4. Speaker placement. One of the easiest ways to avoid feedback is to place the speakers as close to the audience as possible and, as far way from you as possible. Look in the manual that came with your system. There are many suggested placements with various seating illustrations.

5. In difficult rooms, use more than one set of audio speakers. Try placing one set in the front of the room and one set in the back of the room. Then, adjust the volume of the speakers nearest the wireless presenter lower than the audio speakers furthest away from the wireless presenter.

6. CVS Designs. The CVS microphones from Cetacea Sound Corp include a high performance uni-directional microphone in all of its system packages. These are more expensive and work much better than standard omni-directional microphones. Do not substitute a microphone of unknown specifications for the one included with your (CVS) Clear Voice System.

7. Astronaut Ceiling Speaker Design. The Astronaut’s proprietary anti-feedback design reduces feedback caused by sound bouncing off of the walls. If all else fails, turn the volume down. The audio speakers always sound louder to the audience than they do to the person doing the talking.

There is now no simple answer.

Every microphone transmitter must have at least one receiver on its own frequency.

The CVS 16 Channel UHF Wireless Microphone can accommodate up to 4 presenters or more in the same room. Therefore, four individual frequencies are available for your application and up to four presenters can be using the microphones at the same time as long as they are on separate frequencies set 3-4 channels apart.

The other related question that often comes up is can a presenter using one microphone use more than one receiver. In other words, can a single microphone/transmitter transmit to more than one set of receivers (listeners/speakers)?

The answer is yes and is quite commonly used in rooms with difficult acoustic demand. Some rooms have odd shapes preventing the sound from distributing evenly and others are just plain noisy. In these cases, using more than one set of speakers, say one set in the front of the room and another in the back of the room, is quite common. All that is required is a second receiver/speaker combination of the same frequency as the first.

To summarize, two presenters cannot talk through one set of speakers. However, one presenter can talk through two or more sets of speakers. This is particularly useful for Assisted Listening and Tour Guide Applications. For more information please see our Application Guides in the Literature section of this web site.

There is now no simple answer.

Every microphone transmitter must have at least one receiver on its own frequency.

The CVS 16 Channel UHF Wireless Microphone can accommodate up to 16 presenters as long as they are at least 250 feet away form each other. However this can be very misleading in a building because the 250 foot range is measured outdoors according to an “Open Field” distance measurement. In a building this range is diminished by the number of walls between each transmitter on the same frequency.

Every time a wall sits between the transmitters on the same frequency their range is reduced by an amount that depends on the construction of the wall.

In the worst case, the CVS 16 Channel UHF will allow four channels to operate within 100 feet of each other if they are separated by four walls. If they are each in a different room, and given the average size of the rooms, this means in a typical school building with 30 foot rooms, the closest room with a redundant channel would be approximately 100 feet away and have four walls between it and the first room. In our testing there has never been any carry-over in these conditions.

Consider also the fact that it is not likely all rooms within the 100 foot range will be operating simultaneously.

Many schools using UHF microphones assign specific channels to each room. This is a good practice to prevent carry-over and it is also a good practice for hearing impaired students who are carrying a CVS16 receiver to each class with his/her own ear piece.
