Connecting Microphones and Speakers
The encoder can be connected to up to four external microphones and
speakers through the audio connectors. The audio connectors support
input and output for line-level audio signals. The connector is a mini-
jack (3.5mm). The pinout is shown in the following diagram.
Audio input and output use the left and right audio connections
normally used on a stereo audio device.
