_Analog X4 Audio/Serial Input Connector
The Makito X4 Rugged analog audio/serial interface provides two (2) mono audio input signals and one mono audio output (for talkback, future use). The talkback output impedance is 75 Ω (Ohms). The signal level is 1 Vrms (or 2.2 dBu) (single ended).
The audio input channels support 48-kHz sample rates with 16-bit PCM data. The audio input channels support up to Vrms (or 2.2 dBu) (single ended) inputs. The input impedance of the audio input channels is 33 kOhms.
The analog audio/serial interface also provides four (4) serial signals and one serial ground. The serial connector supports RS-232 and RS-422 operation.
