TOPIC: can I connect directly to a speaker?

can I connect directly to a speaker? 6 years 1 month ago #70

Yes. The GinSing hardware has a built-in NJM386 low power audio amplifier. This IC is a more efficient version of the tried and true LM386, but has higher power dissipation and can operate at a lower voltage.

To connect a speaker, you can solder wires (or screw terminal ) to the SPKR contact pads on the board. The speaker should be a minimum of 8 ohms with a minimum power rating of 2 watts. You can also daisy chain additional speakers if desired.

If you wish to get better frequency response ( particularly if you want to hear sounds below 100 Hz ), we recommend connecting the GinSing to a Hi-Fi system instead of using the speaker contacts as most low power speakers have low audio quality.
