More than likely your setup has a cable plugged into the Audio Out port on your projector which takes the HDMI audio in, and sends it to your speakers. You will need to split your audio at this point using a 3.5mm Audio splitter.
You will:
Remove the audio cable from the Audio Out port on your projector
Plug the splitter into this port
Plug the audio cable that you removed into the splitter – this will reconnect your speakers to the projector
Connect your audio cable for the FM/DM system to the splitter
Plug the audio cable into the FM/DM transmitter.
You may need a longer cable than normal for this, especially if this is a permanent installation.
3.5mm Audio (You plug in an audio cable and a HDMI)
If you plug a 3.5mm audio cable into your computer, you have the easiest setup.
You will need:
2 x audio cables
1 x FM/DM Transmitter
1 x 3.5mm audio splitter
Instructions:
Connect the male part of the splitter to your computer audio jack
Connect the cable from your speakers that used to go to your computer into one of the female splitter jacks
Connect the additional audio cable to the other female splitter jack
Finally plug in the other end of the audio cable into the FM/DM transmitter unit
USB Audio (Your sound doesn’t work without the USB Cable)
To use a splitter in your setup with USB audio, you will need to replace your USB cable with a 3.5mm to RCA cable. This has one end which looks like a headphone cable and then two larger round ends which can connect to your SMART Board USB Speakers.
You will need:
1 x 3.5mm to RCA Cable
1 x audio cables (3.5mm to 3.5mm)
1 x FM/DM Transmitter
1 x 3.5mm audio splitter
Instructions:
Connect the male part of the splitter to your computer audio jack
Connect the 3.5mm end of the RCA cable to the splitter
Connect the RCA end of the cable into the Dual RCA input in the speaker (as shown in the second image on the left)
Connect the additional 3.5mm audio cable to the other female splitter jack
Plug in the other end of the audio cable into the FM/DM transmitter unit
You are now sending audio to the speakers via the RCA cable instead of using the USB audio which we cannot split and send to the FM/DM Transmitter.
You will still need to connect the USB cable to your computer, as it is required to connect the touch aspect of your SMART Board. You will need to change the audio output of your computer to the headphone port instead of the USB audio.
