Page 12: Introduction To Alexa
Introduction to ALEXA Introduction to ALEXA ALEXA is a 35 format film-style digital camera made by ARRI, the world leader in professional cinematographic imaging. It combines leading edge digital technology with film camera features that have been refined over more than 90 years of ARRIs history. The result is a camera that allows cinematographers with a film background to shoot digitally without the need for a extensive training.
Page 13 The fan itself is very silent, so the camera noise level is below 20 dB (A)* - this is the same as with ARRI sync-sound film cameras. If the fan noise level starts to increase due to fan aging, the fan can be swapped in a matter of minutes by a trained technician.
Page 14 Introduction to ALEXA High speed image capture In Regular Speed mode, ALEXA has a frame rate range from 0.75 to 60 fps. By adding a license key for High Speed mode, the frame rate range of the camera can be extended up to 120 fps.

Page 19: General Precautions
Electromagnetic Interference ALEXA meets EC regulations by fulfilling the specifications of the European Directive 2004/108/EC (15th December 2004). This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules.
Page 20 To reduce the risk of condensation:  Find a warmer storage location.  Attach the ARRI air-drying cartridge (silica bottle) to the PL-Mount of the camera during storage (NOT during transport!)  If camera needs to be stored in a place that is considerably cooler than the location where it will be used, consider keeping the camera powered from a mains unit in addition to using the air-drying cartridge.
Page 21: Power Supply
Manipulation of power supplies can result in severe damage to the equipment and humans, including death. ALEXA accepts an input voltage range from 10.5 to 34 V DC. The camera can be powered through the BAT connector or can be equipped with battery adapters accepting V-Lock or Gold Mount batteries.
Page 22: Bat Connector
Power Supply BAT Connector The BAT connector of ALEXA is a Fischer 2-pin socket located on the bottom back of the camera right side. The socket accepts power cables KC-20S and KC-29S. The cables can either be connected to the mains unit NG 12/26R or to 24V Cine-style batteries with three-pin XLR outputs.
Page 23: Onboard Batteries
V-Lock batteries are available from a number of manufacturers. Some of these batteries are able to transmit information on their remaining capacity to the camera. ALEXA displays the remaining capacity in percent on the Homescreen of the camera display. For these batteries, the user does not need to set the battery warning level due to the communication of camera and battery.
Page 24  Move the battery upwards and remove it. Figure 8: ALEXA with BAB-V and V-Mount battery Note: Not all V-Lock batteries deliver enough power to supply the camera. We recommend to not use any batteries with a capacity of less than 90 Wh to prevent damage to the battery and unpredictable camera behavior.
Page 25: Gold Mount Batteries
Gold Mount is the battery mounting system of Anton Bauer batteries. The batteries transmit information on their remaining capacity to the camera.

Page 105 SxS PRO cards have to be formatted in the camera before they can be used for recording. ALEXA uses an UDF file system. This file system is read-only for computers, which means data can be copied from the card to another device, but the data cannot be manipulated on the card itself.
Page 106 Operation of The Camera File naming scheme ALEXA automatically names files as they are created on the SxS card. While it is possible to change the file names later on a computer, it is not recommended, as the ALEXA naming scheme has been developed to minimize the risk of duplicate file names.
Page 107 Alternatively, reel name is used sometimes. The tape name of ALEXA files is limited to 8 letters to match the CMX 3600 EDL standard. It consists of the Camera Index, reel counter and the Camera The tape name of the clip from the previous example would then be: A004R1JL.
Page 108: External Recording
Operation of The Camera 12.1.2 External recording Uncompressed HD and unprocessed ARRIRAW data is available via the REC OUT for recording with external devices. The preferred output format also depends on the application. As a rule of thumb, the following guideline can be used: ...
Page 109 ARRIRAW is the name of raw data from ARRI cameras. Raw data is the sensor image data before it is converted to RGB images. As ALEXA has a single sensor with a Bayer pattern color filter array, this means that every pixel only has information of one color channel.
Page 110: Parallel Recording
Operation of The Camera 12.1.3 Parallel recording Recording to both SxS PRO cards and external devics at the same time requires additional attention from the user. First, it has to be determined what function the two sets of data have. For example, the internal recording could be used for on-set review and proxy editing, while the external device captures the master data.

Page 114: Syncing The Sensors Of Two Cameras
Operation of The Camera  Variations: If the shooting starts close to midnight, the TC might be started with an offset to prevent a rollover at midnight.  Restrictions: Only possible if the camera is running at sync-sound speed. If the camera is over- or under-cranking, the TC frame rate will no longer match the sensor frame rate, so that TC values would either be duplicate or dropped.
Page 115: Syncing The Settings Of Two Cameras
Syncing the Settings of Two Cameras It is possible to operate two ALEXAs with synchronized settings. Camera connection Connect two ALEXAs with the ALEXA Ethernet/Ethernet Cable KC 156-S, or with the ALEXA Ethernet/RJ-45 Cable KC 153-S over an Ethernet hub. Camera setup Go to MENU>SYSTEM>EXT SYNC, and set "Settings sync"...
Page 116 Operation of The Camera The cameras will automatically negotiate IP addresses. After about 5 seconds, connections are established. The master camera will initially distribute its settings to the slave camera. Once this is done, settings can also be changed on the slave camera, and the change will take effect on both cameras.
