FAQ and trouble shooting, wireless products

FREQUENTLY ASKED QUESTIONS

____________________________________________

What affects the wireless range?

The wireless range is room to room 20m, in same room 50m, and in open space/ line of site, 100m. The range depends on your type of walls, for example steel reinforced concrete has large negative effect. Wood and dry walls have less effect on the range. If there are many wifi networks in the area, this can also reduce range. 

 

Can I mix lIVING speakers with wf100 dongles?

Yes, these products use the same network. If you have a Living speaker system, you can add RX100 receivers to expand your wireless network to include more products.

 

Can I adjust volume in different zones/rooms? 

Yes, but only LIVING speakers have the Zone volume control feature. The volume is controlled by the enclosed remote. With WF100 you have to adjust volume on the devices to which the dongles are connected.

 

Why can’t I use the usb 2.0 input on my stereo for the RX100 receiver?

The RX100 only has an analog output, the USB connector is only used for power supply. RX100 receiver should always be connected via cable as well as to a USB power supply.

 

What operating systems are supported?

Windows XP (min. service pack 2) , Vista and Windows 7

Mac with OS X 10.xx 

 

 

What can I connect to the WF100 system?

As the WF100 dongles incorporate A/D and D/A converters and analog input/output, you can connect to any device with sound input (RX100 receiver) and sound output/headphones (TX100 transmitter). 

 

 

What music files are supported?

WF100 incorporates advanced Burr Brown A/D and D/A converters and can be used to play all types of sound file formats. Even uncompressed music files such as FLAC and Apple Lossless will play with full CD quality. Full CD & DVD sound is supported.

 

Can I connect Living speakers to my stereo?

Yes. The easiest way is to connect the TX100 transmitter by cable to the headphones jack, and then to a USB power supply. Volume is adjusted on the stereo.

If your stereo is equipped with a variable level pre-out, you can connect it to this as well. If the pre-out is a fixed level, you will not be able to adjust volume on your stereo, you will need to adjust volume with the Audio Pro remote.

 

Can I adjust volume on RX100 receivers?

No, RX100 can not itself adjust volume levels. Adjust the volume on the device to which the RX100 is connected. Or on the device from which you are sending music via the TX100 transmitter. 

 

Do I need to install any software?

No, no software is needed. Just plug n’ play! 

 

How does the network avoid interference?

The Audio Pro Network uses a dedicated proprietary protocol.

Using frequency hopping before listening, we switch channels before we get any interference. We progressively monitor our audio bands.

We have a built-in “sniffer” system to sniff out any other wireless channels which may potentially give interference. This “sniffer” system automatically jumps between free RF(Radio Frequency) channels so no noise interference will occur. This ensures that the Audio Pro network will seamlessly coexist with other wireless systems. We have built-in security that filters all unnecessary RF interference from other wireless networks.

There are 2 built-in antennas which work like a diversity antenna. By having these we can automatically select the strongest signal on not only the RF channels but also on the antennas as well. If any interference is present on one antenna we will automatically switch to the other antenna.

Our bandwidth is 1.6 Mb it per House-Code channel. All audio is run at 48 kHz to give better audio perfo rmance. 

 

What is meant by no audible timedelay?

The Audio Pro network is very fast. Time delay is a mere 15ms, not audible to the human ear. This means that if you send audio to multiple receiving units as Living speakers or the RX100, you will not hear any delays in the audio sent. 

Note: for modern home theater receivers, time delay can occur due to longer sound processing of the audio signal in the home theater receiver. The delay only occurs when transmitting wirelessly to a home theater receiver, not sending wirelessly from the receiver to Living loudspeakers or RX100. 

Delay problems with home theater receivers are only audible when using RX100 receiver or Living speakers at the same time as the home theater receiver. Living speakers and RX100 process the sound signal faster than a home theater receiver.

TROUBLESHOOTING WIRELESS

 

Are you using more than one TX100 transmitter?

Make sure that the TX100’s aren’t running on the on same House Code. If more than one TX100 uses the same House Code, interference may occur. Disconnect one TX100, or change the House Code.

 

Are you using the same House Code on transmitter and receiver?

Make sure the same House Code is set on both the transmitter and the receiver.

 

How far apart are the transmitter and receiver?

If distance between the transmitter and receiver is too far, the, connection might be lost. Try placing the transmitter and receiver in closer proximity, does this help?   

 

Are there walls between the transmitter and receiver?

If your home has thick concrete walls, or walls of plaster with wire lath, the wireless range will decrease. Try placing transmitter and receiver in the same room, does this help?   

 

Are there more wireless networks in the area?

If there are many wifi networks running in the area, wireless range can decrease. There are useful apps for iPhone/iPad/iPod touch and Android to detect local wifi networks, and see which channel might be crowded.

You can also try to change the channel on your wireless router to improve Audio Pro network range and your own home network wifi performance. (Audio Pro network transmits on channel 1, 6 or 11.) 

 

Are you using MAC or PC?

If you use Macbook Pro or Mac Mini, there can be conflicts with the internal wifi network cards in the computer. This is because the USB sockets are too close to the internal network card. Try connecting the TX100 by cable to the headphone jack (and to USB power supply) and place the TX100 away from your computer, does this help? 

 

Is your computer connected to the internet via cable or wifi?

The Audio Pro network can weaken a local wifi network (but not weaken itself). 

If possible, you should change channel on your wireless router, the Audio Pro network transmitts on channel 1, 6, or 11. Choose a new channel on your router, for example 3, 8 or 13. (in total there are 13 channels on the 2.4GHz band.)

There are useful apps for iPhone/iPad/iPod touch and Android to detect local wifi networks, and see which channel might be crowded.

If you cannot change the channel on your wireless router, try connecting computer via Ethernet cable instead. Does this help?

 

Are there Bluetooth units active in the area?

Shut down all active Bluetooth devices. Does this help?

 

Is the LED light on the transmitter blue?

If the light is red, try moving the transmitter and receiver closer together.
Does this turn the LED blue?

 

Windows 7 and Mac OS, select sound output

When connecting the TX100 transmitter to a computer  using Windows 7 or Mac OS, you need to select the sound output. Go to: system settings, find sound settings, and select USB HEADSET as your sound output. (In older Windows OS there is no need for this, TX100 will take over automatically as the sound output device.)

What amplifier should I use with my Audio Pro speakers?

The sound quality of your system will never be stronger than its weakest link. If you spend good money on high-quality speakers, then you should make sure that the rest of your system is of comparable quality. A well-recognized brand that has received good reviews is always a good investment, and your hi-fi dealer can also recommend components that complement your speakers. Remember, however, that a speaker’s sound reproduction may differ slightly from one set of components to another, so it is always best to (a) test the alternatives, and (b) let your ears be the final judge. Your taste in music also plays an important part in the kind of system you choose. 

The label on the back of each speaker states the power capacity of the amplifier that should be connected to it. This website also provides detailed technical information about the recommended amplifier capacity for each speaker in our range. Please note, however, that the amplifier’s power capacity (measured in amperes) is more important than its effect (measured in watts) when you want to know how well an amplifier can drive the speaker. 

 

Power, or current – which is most important for an amplifier?

One of the most used terms in HiFi is ‘watt’, the measurement unit that describes how much electric energy an amplifier can deliver per second to a speaker, and how much energy per second the speaker is capable of receiving. But a watt is a measurement of quantity -- how loud the music can be played -- rather than quality. 

The amplifier’s quality is more closely related to its ability to deliver current to the speaker. A speaker needs current in order to be able to transform the electrical music signal into music that pleases the ear. Current strength is measured in amperes, and the more current the amplifier can deliver to the speaker, the better the speaker will reproduce the music. A good speaker can dynamically deliver between 50 and 100 amperes. 

 

What is impedance?

Impedance is a measurement of resistance. The speaker’s resistance defines how difficult the speaker is to run. Resistance is measured in ohms. The lower the ohms, the “easier” it is for the amplifier to run the speaker. A speaker’s impedance -- or electrical resistance as a function of the frequency -- is a measure of the electrical load placed on the amplifier by the speaker. The greater the impedance, the smaller the amount of current flowing through the speaker will be. 

A speaker’s normal impedance is 4 or 8 ohms. This means that a speaker with an impedance of 4 ohms needs an amplifier that can deliver more current. The lower the impedance, the higher the demand has to be that is placed on an amplifier. 

 

Will I have a problem with Audio Pro’s 4-ohm speakers?

For instance, a 4-ohm speaker can easily ‘empty’ an amplifier of its current reserve. Therefore, be careful when connecting double pairs of loudspeakers. The amplifier looks upon two pairs of 8-ohm loudspeakers as 4 ohm. (Note that this does not apply when setting up a home theatre system.) 

Audio Pro has many loudspeakers designed as 4-ohm. We do this simply to give you more sound value for your money. In our case, if a speaker measures less than 6.4 ohms, we describe it as 4-ohm. They won’t give you any impedance problems. Many amplifiers specify 8 to 16 ohm, or maybe just say “minimum 8 ohm”. This is a clear indication that the amplifier is of lower quality. 

In a home theater set-up, there will be no problems unless the amplifier is of very poor quality. With two pairs of speakers (where all speakers are 4-ohm), there may be a problem if they are connected to both the A and B outputs and are played at the same time. The amplifier will go quiet and will go into protection mode. It won’t break. We don’t know of any case where the impedance caused problems in a home theater set-up of Audio Pro speakers.

Normally, a speaker that is under 6.4 ohm is described as 4-ohm. If greater than 6.4 ohm, it is described as 8-ohm. 

 

What speaker wire should I choose in my sound system?

Your sound system will never be better than the weakest component. If you have put your money into expensive electronics and speakers, you should also look at your choice of speaker wire. Wire of good quality can make a difference in how your sound system performs. The best wires are made of higher-grade copper, which has excellent conductivity. Wires come in several thicknesses. Choose a thick cable, at least between 12 – 16 AWG (American wire gauge), which suits most systems of good quality. The speaker wire can be connected between speakers and receivers/amplifiers in different ways. It is best to choose electronics and speakers with heavy-duty nickel- or gold-plated binding posts that accept bare wire, banana plugs or spade lugs. It is also an advantage if there is a good amount of space in the area around the binding posts, allowing you to have ample maneuvering room for your fingers so that speaker wires can be securely fastened.

 

How do I correctly connect my new speakers?

The wires between amplifier and speaker must always be 100% correctly connected. Otherwise your system will sound strange. Always connect with marked wires (color coded or patterned). This reduces the risk of a mistake. The same is true for the connection to the amplifier. 

 

What happens when the speakers are incorrectly connected? 

When the wires to the left and right speakers are connected differently (for example + to + on the left speaker and + to – on the right speaker), then the drive units will play in counter phase. This means that when one speaker’s drive cone is moving inwards, the other speaker’s drive cone is moving outward. This makes the bass sound disappear almost completely, because the sound waves will cancel each other out. 

 

How to check that phase is correct? 

By turning the speakers so that their fronts face each other, you can hear whether you have connected the phase correctly or not. Play music with some strong bass in it and, if the bass sound disappears with this placement, then the wires are incorrectly connected. Change the + and – cable connection on one of the speakers (not both!). If the bass sound increases, then it is now correct. 

 

My brand-new speakers sound ‘wooden’ and all-round poor. Is there something wrong with them?

This need not be a fault of the loudspeaker. A brand new speaker has never been used, and its membranes and mountings are stiff to begin with, which may result in a slightly unsatisfactory sound. Like a new car, the speaker needs to be ‘broken in’, and the more it is played the better it will sound. A good rule is to not judge the speaker until is properly broken in, and this may take from 100 to 200 hours of playing time, depending on the model. To expedite this process you might, for example, switch on your radio before you leave for work, and let it ‘exercise’ the speakers until you come home. If you nonetheless feel that an unsatisfactory sound reproduction is due to a fault of the loudspeaker, you should contact your retailer as soon as possible.

 

Are bookshelf speakers or satellites just as good as larger tower models?

It all depends. A loudspeaker must move a lot of air in order to sound good. The larger the cabinet, the more air the speaker can move. But sound quality is also affected by the speaker’s quality – the cabinet’s composition and construction, and the speaker’s components. Even the speaker’s location, the room it is in and the room’s other furnishings will affect the sound quality. If the room is sufficiently large and you have no objection to prominent loudspeakers, they will undoubtedly sound very good. But smaller speakers are more appropriate to a more limited space and, because of their smaller size, they can usually be more easily maneuvered until you have a fully satisfactory sound picture. Small satellites cannot be played as loud as bigger speakers, and they often are unable to perfectly reproduce the lower bass tones. For this reason, a subwoofer is a worthwhile addition to a satellite system, as it will help ‘round out’ the sound picture with a strong lower register.

 

Do I need a subwoofer?

A subwoofer is a speaker specifically designed to reproduce low bass tone – frequencies below 100 Hz. By adding a subwoofer to your speaker system, you will direct the deep bass register to it. This reduces the load placed on the other speakers, enabling them to more faithfully reproduce the mid-range and treble registers. The end result is a clear improvement in overall sound reproduction, and you will discover sounds that you never heard before in your old discs and films.

 

What does Audio Pro’s ace-bass® technology do?

Ace-bass® technology gave Audio Pro its start nearly thirty years ago, and the problem it solved is just as valid today. Bass reproduction usually requires moving large volumes of air, which dictates large, obtrusive enclosures and elements. Ace-bass technology enables us to build subwoofers that deliver a deep, clean, fast and powerful bass reproduction from a surprisingly small enclosure. Ace-bass uses electronics to affect the bass element’s mechanical characteristics in such a way that the element ‘believes’ that it is working in a much larger enclosure than it actually is. This is equally true for music- and home theatre sound reproduction.

 

How can I hook up my powered subwoofer?

Connection to amplifiers without sub-out 

Connect left- and right speaker wire from the amplifier to Speaker Level IN on the subwoofer. Then connect the speaker wire from Speaker Level OUT on the subwoofer to the left and right side speakers. This allows the Audio Pro subwoofer to always be connected to the system. Speakers that are connected this way have a limited bass at approx. 100Hz (called HI-PASS). 

 

Connection to amplifiers with sub-out 

Connect the enclosed low-level cable from the amplifier’s SUB-OUT to LINE IN on the subwoofer. NOTE! With this connection, the speaker level output won’t work – the speakers must then be connected through the regular amplifier. With the LO-PASS frequency control, you can adjust to how high a frequency the sub will perform (i.e. its upper limit). With the control LEVEL you can adjust the volume of the subwoofer. 

 

Which Audio Pro subwoofer should I choose?

All our subwoofers can be used for both HiFi and home theatre systems. The best advice we can give is to let your personal taste decide. Test each one that interests you, preferably together with the other speakers and components that make up your sound system
