    Hello all,

    First post! I'm new to electronics and self-taught. I'm mostly interested in musical and audio applications of this stuff for building synthesizers, audio effects, and other audio equipment.

    In many schematics that I have found, multiple parts of the circuit are connected to ground. In a portable, battery-operated unit, what should I connect these points to? The negative battery terminal?

    Thanks!!

    Hello,

    Yes. In a battery operated device the minus of the battery is the ground, if the device has single powersupply.
    If the device has dual powersupply the center connection between the plus and minus of the two batteries.

    Greetings,
    Bertus

    PS if you are interseted in making syntesizer stuff take a look at this website:

    Since you are new to electronics it might not be too late to prevent you from developing the habit of using the word "ground" in the cavalier manner which I so often see.
