CONNECTING AN EXTERNAL AMPLIFIER
To amplify your Concertmate 410’s sound, you can connect it to an exter- nal amplifier (not supplied) using an audio cable (not supplied) with a 1/8- inch plug.
To connect an external amplifier to your keyboard, insert the cable’s plug into the PHONE jack on the back of the keyboard, and connect the other end of the cable to the amplifier’s input jack(s) (such as AUX IN or TAPE IN).
