Silent Disco King

Frequently Asked Questions

General

Can I use my mobile phone, laptop or iPod for a Silent Disco?
Yes! You can pretty much connect anything that makes a sound to the Over Ear wireless headphone system.
Can I play podcasts, playlists, Spotify, Pandora or You Tube on my wireless headphones?
Yes! Anything that you could normally listen to on headphones or speakers can be connected to the transmitter and enjoyed by unlimited numbers of people using our wireless headphones. Make sure your playlist is available at your venue - for example check there is a reliable wifi connection for live streaming, or download the playlist to your local device to avoid the risk of disconnection
Can I use Over Ear wireless headphones to watch a film, TV, Netflix, Sky, DVD or Blue Ray?
Yes! Just connect the audio output to the transmitter. Many TVs, DVD players and Blue Ray devices have an audio output on the back. This is the best way to connect, but you can also use the headphone output. Check your specific device to make sure it has suitable output audio connections.

Headphones connected in this way can be useful if for example one member of the family enjoys watching TV at a louder volume; or for someone to play an Xbox game without the whole room hearing the sound. They can also be used (with multiple transmitters set up) to enjoy different things in the same room - for example 3 people listening to a film, while someone else listens to the playstation.

Professionally the Over Ear wireless headphone system is used by many outdoor cinemas. Wireless headphones means people can listen to the film without disturbing neighbours. It also means that traffic, wind, aeroplanes and other noise pollution won’t interfere with enjoyment of the film. Professional Cinemas also use the Over Ear system to show films in multiple languages simultaneously.

What is the Over Ear system?

The Over Ear system is an agreed standard to which all Over Ear equipment is made.
The advantages are:
1) Ease of use
Just switch on your headphones and they work. They automatically detect how many transmitters are in use at any time, and will only switch to live channels.

2) Future Proof
Buy headphones now, add more in a month or year.
You can start with one channel, and add a second or third in a year. Your existing headphones will automatically work with these - no reprogramming required.

3) Multi Product compatibility.
Start with any transmitter or headphone, and buy different ones infuser. They’ll all work together.
For example if you buy a bob headphone now with a Donkey Transmitter, you could add a belt pack next month and an owl transmitter in a year.
With this set up you’d be able to listen to 2 channels of audio on both Bob and the belt pack.

How do i connect an ipod/laptop/mobile phone?

Playing music from an iPod, Laptop or mobile phone Just plug the audio cable into the headphone socket, and the other end into the transmitter. Choose your playlist, hit play and turn it up (your device should normally play at 70-100% of full power for optimum results) Audio cable is supplied

How do i connect a DJ?

Connect the master output of the DJ mixer to the transmitter with the supplied audio cable. This is normally where the amplifier is connected, and usually the transmitter connection will replace the amplifier connection. Most DJ mixers have Red and White RCA/Phono outputs. If your DJ mixer has XLR or 1/4” Jack outputs you’ll need an adapter. You can also connect to the record output or DJ booth output to the transmitter.

How do i connect a band?

The transmitter should be connected to the output of the master mixer (which all the instruments and microphones are connected to). You can also use the Aux or Bus outputs particularly if you wish to mix different elements for the headphones.

How do i connect a P.A? (ie microphone for a guest speaker at a conference)

The microphone should be set up through a mixing desk as with a traditional loudspeaker set up, connect the transmitter to the audio output instead of the amplifier. Extra devices (such a multiple microphones or laptops) should also be connected to the mixer.

How many Silent Disco headphones can i connect at once?

You can connect an unlimited number of headphones and receivers at once without any loss in signal, sound degradation delay.

Is there latency on the system?

No, there is considered to be zero latency on the system. Unlike digital systems which require processing time to encode then decipher signals, the Over Ear system uses wireless RF technology. This conveys signals throughout the chain at the speed of light resulting in now perceptible delay in hearing audio.
