CAM ANALOG and PRO I/O ANALOG (Microphone)
The camera provides two (2) microphone jacks for recording two (2) channels of microphone level analog audio. The Pro I/O Module provides two (2) XLR connectors for recording two (2) additional channels of microphone level audio. The sensitivity of the microphone and the pre-amp gain determine the recording level of the microphone input.
PRO I/O ANALOG (Line In)
The Pro I/O Module provides two (2) XLR connectors for recording two (2) channels of line level analog audio. Line input passes without gain through the system. The signal provided by the field production mixer or other external line level source determines the recording level of the line input.
NOTE: Line level audio is only available via the Pro I/O Module.
PRO I/O AES A/B (Digital Input)
The AES connector on the Pro I/O Module allows an input of 24-bit, 48 kHz AES digital audio.
NOTE: Digital input audio is only available via the Pro I/O Module.

- Gain Sliders: Ensures that each pre-amplifier (Pre-Amp) slider has the same value. If you select the check box while the sliders have different values, you must change one (1) slider for all sliders to sync up.
- Volume Sliders: Ensures that each headphone (Headphone) slider has the same value, so that you can control the master volume for headphones. If you select the check box while the sliders have different values, you must change one (1) slider for all sliders to sync up.
Channel Name
You can rename each audio channel. The default names are Ch1, Ch2, Ch3, and Ch4. The channel names display in the Audio Meter, but are not included in the clip metadata. For more information, go to Audio Meter (VU Meter).
Channel Modes
Match the channel mode to the incoming audio signal.

BALANCED |
CAM ANALOG, |
Balanced microphone input. Enables the 48V phantom power option. Typically used with microphones that have XLR connectors and internal batteries. |
|
UNBALANCED |
CAM ANALOG, |
Unbalanced microphone input with 3.3V bias. Disables the 48V phantom power option. Typically used with unpowered microphones that have 3.5 mm TRS plugs. |
|
LINE |
PRO I/O ANALOG |
Fixed input gain with limiter settings if limiter is enabled. Disables the 48V phantom power option. |
|
AES |
PRO I/O AES A, |
Only mode available for AES input. Disables the limiter and 48V phantom power options. |
Phantom Power (48V Power)
Select the 48VPower check box to enable 48V phantom power for an audio channel. The 48V phantom power option is only available when the channel mode is set to BALANCED.
Limiter
Select the Limiter check box to add a limiter to the analog input signal chain. Use the limiter in dynamic environments where external mixers are not practical for controlling signal strength. The limiter is only available with analog audio input.
Pre-Amp
The pre-amplifier range is 30 dB to 60 dB. The default is 32 dB. To adjust amplification levels, follow the instructions below:
- Go to Menu > Settings > Audio > Pre-Amp.
- Move the Pre-Amp (pre-amplifier) sliders up and down to adjust the amplification levels.
- To link the amplification for each channel, go to Menu > Settings > Audio > Channel and select the Gain Sliders check box. For more information, go to Link.
