The jacks are compatible with M6 x 0.5 threaded lockingcollars.• In: Balanced or unbalanced input for a mono microphone or line signal.• Out: Audio out (line level), that can be connected to a public address (PA) system or an active speaker withbuilt-in amplifier. A stereo connector must be used.For best audio quality and when using long cables, use a balanced microphone and shielded cables. For a more secureconnection, threaded audio connectors are recommended. In this case, the audio mounting nut will need to be removed seeOverview, on page 5.Pin Full-duplex, half-duplex, simplexunbalancedSimplexbalanced1 Tip Microphone/Line in + Microphone/Line in2 Ring Line out - Microphone/Line in3 Sleeve GND GNDVideo Inputs - AXIS Q7414 supports 4 video sources. Each video input is terminated using a coax/BNC connector. Physicalconnections made using 75 Ohm coaxial video cable have a recommended maximum length of 800 feet (250 meters).Note:AXIS Q7414 does not have physical line termination DIP switches. If the product is to be connected in parallel with other equipment,75 Ohm video terminations can be enabled/disabled on each input in the product's web pages at Video & Audio > Video Input >Video termination.• Microphone in (selectable 2.0V, 2.5V, 3.0V bias voltage)• Line in• Line out• Microphone in (selectable 12V phantom power)• Line in123123
