RCA Cable
A RCA Cable has a regular 3.5mm headphone connector on one end, and two separate left and right connectors on the other end. These separate connectors are larger and require a separate input for the left and right audio channels.
In your setup you may use these with the SMART USB Speakers, or find them in the back of a projector
Audio Splitter
This takes a standard 3.5mm audio connector and splits the signal so that it can be sent to two devices. These are fairly easy to come by, and inexpensive.
FM/DM Transmitter
This is the microphone part of the FM/DM System. It is worn by the classroom teacher, to send a direct signal to the students receiver which attaches to their hearing aids, Cochlear implant or the Bone Anchored system. These come in different types. The one shown here is the Phonak Roger Touchscreen Mic. This has an input which you can see has a 3.5mm audio cable plugged into it, sending the signal from the TV to the transmiter.
Most of these units will not allow the student to hear what is happening in the class and listen to the computer/TV audio at the same time.
Roger Multimedia Hub
The Roger Multimedia Hub allows students to connect to the hub which can be used to mix the audio from the media source and from the Roger Touchscreen Mic. This unit has the advantage of not having to plug and unplug the FM/DM Transmitter throughout the lesson in a media heavy environment. You should refrain from speaking at the same time as the media is playing. Even though the unit makes this possible, this would introduce multiple audio sources to concentrate on.
You can read more about using it on the dedicated page 🔗.
Assistive Listening Devices
Assistive Listening is providing an audio signal to a person to help them to hear. This can be achieved by using an FM/DM system, using a T Coil Loop, or a dedicated system.
This can be achieved in an Auditorium or Theatre space where the audio signal in the space is passed into a device designed to service a number of listeners. There are a number of solutions which can be used:
- Output to a Roger Mic paired to multiple users*
- Output to a Roger Multimedia Hub paired to multiple users*
- Use of a Roger Basestation*
- Use of a WiFi based Assistive Listening Solution such as Listen Everywhere.
* These options require all of the listeners to be using Roger Receivers
