5.8.3 Using audio

Two high quality audio channels are available in the Triax mode. Set the gain levels (-22 to -64 dB) for these channels in the AUDIO section of the INSTALL menu. A high-pass filter for each channel can also be switched on via this menu.

Audio channel 1

The channel 1 input socket selection switch selects either:

•the socket at the front-right of the camera, or

•the Mic 1 audio channel 1 connector at the rear of the adapter as the input for channel 1.

The rear input level switch selects either a line level input or a microphone level input for the channel 1 rear connector. The line level input sensitivity is 32dB lower than the microphone input sensitivity.

The switch under the Mic 1 socket selects a phantom power supply (48V) for the rear socket. Phantom power (48V) is always present on the front-right microphone socket.
