| Digital Audio Input | Optical (TOSLINK) or coaxial digital input connectors |
Using an Audio Cable
To connect speakers to your Promethean board without using Wi-Fi, you’ll need to use an audio cable. An audio cable is a type of cable that carries audio signals from one device to another. In this case, you’ll be using an audio cable to connect your Promethean board to your speakers.
To connect your speakers to your Promethean board using an audio cable, follow these steps:
- Locate the audio output port on your Promethean board. This port is typically located on the back or side of the board.
- Connect one end of the audio cable to the audio output port on your Promethean board.
- Connect the other end of the audio cable to the audio input port on your speakers.
- Turn on your Promethean board and your speakers.
- You should now be able to hear audio from your Promethean board through your speakers.
Choosing the Right Audio Cable
There are a few different types of audio cables available, so it’s important to choose the right one for your needs. The type of audio cable you need will depend on the type of audio output port on your Promethean board and the type of audio input port on your speakers.
The most common type of audio cable is a 3.5mm stereo audio cable. This type of cable has a 3.5mm connector on each end. 3.5mm stereo audio cables are compatible with most Promethean boards and speakers.
If your Promethean board has an XLR audio output port, you’ll need to use an XLR audio cable. XLR audio cables have a 3-pin XLR connector on one end and a 3.5mm connector on the other end.
If your speakers have a TRS audio input port, you’ll need to use a TRS audio cable. TRS audio cables have a 3.5mm TRS connector on one end and a 3.5mm TRS connector on the other end.
Here is a table that summarizes the different types of audio cables and their compatibility with Promethean boards and speakers:
| Audio Cable Type | Promethean Board Compatibility | Speaker Compatibility |
|---|---|---|
| 3.5mm stereo audio cable | Most Promethean boards | Most speakers |
| XLR audio cable | Promethean boards with XLR audio output ports | Speakers with XLR audio input ports |
| TRS audio cable | Promethean boards with TRS audio output ports | Speakers with TRS audio input ports |
Connecting via Bluetooth Transmitter
Utilizing a Bluetooth transmitter offers a convenient solution for connecting speakers to your Promethean board without the need for Wi-Fi. Here’s a step-by-step guide:
- Acquire a Bluetooth Transmitter: Purchase a Bluetooth transmitter compatible with your speakers. These devices typically feature a 3.5mm audio jack or an optical input, allowing you to connect them to the Promethean board’s audio output.
- Connect Transmitter to Board: Using the appropriate cable (usually a 3.5mm audio cable or an optical cable), connect the Bluetooth transmitter to the audio output port on your Promethean board. Ensure that the cable is securely attached at both ends.
- Pair Transmitter and Speakers:
Pairing Process
The pairing process varies slightly depending on the specific Bluetooth transmitter and speaker models you’re using. In general, you’ll need to follow these steps:
- Power on the Bluetooth transmitter and make it discoverable by putting it in pairing mode. Consult the device’s manual for specific instructions on how to enter pairing mode.
- Put your speakers into pairing mode as well. Again, refer to the speaker manual for guidance.
- On your Promethean board, open the Bluetooth menu. The location of this menu varies depending on the board model. Once open, search for available devices and select the name of your Bluetooth transmitter.
