Clever use of the three square wave voices could be used to generate a range of other sounds, such as explosions. A keystroke could be accompanied by an audible feedback signal. Audio was output from an RCA (Tulip) connector onto which an eight ohm speaker could be directly connected, but the JR-200 also had a small built-in speaker.
