Classroom Audio Troubleshooting (Epson Brightlink Classrooms)

Step 1: Check that the HDMI cable is connected properly to both the Epson pilot and your laptop. 




Step 2: Confirm that your laptop’s sound output is set to “EPSON PJ.” 


Go to System Preferences > Sound > Output and select EPSON PJ. If you do not see EPSON PJ as an option, the cable is likely either not plugged in properly or not working.


Step 3: Check that the wall amp is powered on.


In all 5th / 6th floor rooms, the wall amp is located just below the Epson pilot. If the amp is on, you will see a green indicator light underneath the Master Volume knob. If the amp is off, turn the amp on by moving the ON / OFF switch to the right.






Step 4: Check the audio cable is plugged into Channel 1.


An audio cable runs out of the wall and should be plugged into any one of the numbered channels.




Step 5:  Confirm that both the Master Volume and Channel 1 volume are turned up enough to be audible.


Turn the volume dials to the right to turn the volume up.




If you’ve gone through all of these steps and sound is still not working, please submit a helpdesk ticket by going to or emailing  You may also dial TECH (8324) on your classroom phone to call the tech office.
