1. Power Button

The power button is used to power on/off the device.

2. Calibration Port

The calibration 2.5mm jack on the rear panel below the power button, allows for the connection of supported calibration devices with support now available for the retail version of the X-Rite i1Display Pro as well as legacy Atomos Spyder Calibrator. Both units utilize the optional USB to serial adaptor cable. The latest version of the Atomos Calibration software is available at www.atomos.com/support

3. Headphone Ports

A 3.5mm headphone jack is located on the rear panel adjacent to the XLR audio connections. Channel selection and volume for headphone monitoring is via the audio controls section in the lower left hand side of the touchscreen.

1. 4K/HD-SDI

4K/HD-SDI in: The SDI input connections are 12G compliant and backwards compatible meaning that it can be used for 12G, 6G, 3G and 1.5G signals. The SDI inputs support 3G in both level A and B standards. This input is also used to input RAW signals from supported cameras.

4K/HD-SDI out: This is for connection to an external monitor or other device with an SDI input. It carries a loop-through of the incoming SDI or HDMI signal in record and standby mode, and the playback signal when the Sumo19 is in playback mode. This output can carry either a 4K or HD signal (with the option to down scale the 4K input to HD). The SDI <-> HDMI conversion is always live allowing for instant conversion without any setup. The SDI outputs support 3G in only level B standards and is not active whilst receiving a RAW signal input

4. Synchronization

Located with the SDI input and output is another BNC connector marked Genlock: Genlock is short for “Generator Lock” in video systems. The Genlock is an input only and will lock the internal timing system in a video device to an external reference signal during play back.

The Genlock BNC can also be used as a LTC Timecode input. This allows for external LTC timecode to be used enabling multiple devices to be sharing the same master timecode signal, which makes it perfect for multi-camera setups. LTC is only available in Record mode and can be accessed via the Time code menu

HDMI and SDI

       Built in to the Sumo19 are are both SDI and HDMI conversion. This means

that either input is able to be routed out of both the HDMI and SDI outputs

2. HDMI

HDMI IN: The video input is a full size HDMI 2.0a connection used to receive the video and when supported by your device embedded audio and Timecode. This is both displayed and recorded to the Atomos recorder/monitor storage media.

HDMI OUT: This is for connection to an external monitor or other device with an HDMI input. It carries a loop-through of the incoming HDMI or SDI signal in record and standby mode, and the playback signal when the Sumo19 is in playback mode. This output is 2.0a and can carry either a 4K or HD signal (with the option to down convert the 4K input to HD). The SDI

<-> HDMI conversion is always live allowing for instant conversion without any setup.

3. Analogue Audio

On the rear panel of the Sumo 19 are the XLR audio input and output terminals. The inputs can be connected. A 2 in 2 out XLR cable is available as an optional additional accessory. The inputs can be configured at Line, Mic and Pro level in the Audio menu. The inputs can also provide 48V Phantom power to compatible microphones.

The XLR outputs are available for monitoring and the audio channel routed to them can be selected via the headphones selection in the Audio menu.

at the same time. This allows you to use SDI cameras with other HDMI equipment or HDMI cameras in an SDI infrastructure. To toggle between SDI and HDMI inputs access the Input Menu (page 19).

Video Scale Convert

Video out also has the option for a down scale to be applied allowing your 4K input to be converted to a 1080 HD output for use with existing HD equipment.

3D LUT Output

When not using AtomHDR mode 3D LUTs can be applied to the outputs of the Sumo 19 and LUTs can also be selected to be applied to the outputs and routed out to other equipment via the HDMI or SDI connections.

Embedded Audio

The Sumo19 can record 12 channels of digital audio embedded in the SDI signal, and 8 channels of digital audio embedded in the HDMI signal.
