No Sound from Audiometer CD player

Are you playing music from the correct CD player?

~ Some booths have 2 CD players in the rack. Ensure you are using the one labeled "Audiometer CD Player"

Is CD selected as the source on the correct switcher?

~ Some booths have 2 identical switchers in the rack (Audiometer Aux In & Mother's Distraction). Ensure the one labeled "Audiometer Aux In" has CD selected as the source.

~ Connect a pair of headphones to the Audiometer Aux In switcher. If you can hear the CD, the issue is downstream in the audiometer or transducers. If you cannot hear the CD, the issue is in the switcher or CD player.

Is the CD you're trying to play a burned CD-R?

~ Sometimes CD players have trouble with burned CDs. This could be due to the type of CD media or perhaps because the author failed to properly burn it for playback on an Audio CD player.

~ Ensure the CD was burned as an Redbook Audio CD (not MP3 CD, not data CD) using CD-R media (not CD-RW, DVD-R, not DVD+R, not BD-R, etc).

~ Ensure that when burned the disc was "closed" by the burning software. "Closing" the disc writes the table of contents to the disc and makes the disc readable by Audio CD players.

~ Try playing a commercially produced Audio CD instead and see if the behavior changes.
