what does a dotted line to ground mean on schematic?

[AltecDarpa]

Hello, I am building a small amp on perf/bread board using NJM2073d in stereo mode, and the schematic has dotted lines coming from a capacitor on each output channel going to ground, does this mean I am supposed to join these grounds together separate from the other grounds in the circuit?


its on page 4 of the data sheet.

thanks for any help

The use of dashed lines in schematics usually indicates an optional component(s) or connection. In this case the inclusion of a capacitor and resistor to control oscillation of this amplifier working in conjunction with certain speaker loads.

Hope this helps 😀

Thanks for clearing that up. it shows the bridged circuit in the oscillation blurb, I wasn't sure if it was the same for the stereo circuit, I am still a noob, lol

thanks again.
