30au Dual Speaker 16hp L

Dual 54mm speaker module with passthrough (Left-side version)

Has a PAM8406-based 5W amplifier with two channels, which are each connected to one of the two 54mm speakers. Level control also functions as a power switch.
There are three jacks:
LS: Left/Stereo. Tip is connected to channel 1, which outputs to the upper speaker. If RM is not connected, the ring connection is sent to the second channel / lower speaker.
RM: Right/Mono. Tip is connected to channel 2, which outputs to the lower speaker. If LS is not connected, the same signal is also sent to the first channel / upper speaker.
SO: Stereo Out. Connect a stereo cable to this jack to receive the channel 1 signal on the tip, and the channel 2 signal on the ring.
