Introduction
The PIX 250i is a rack-mountable, production video recorder with extensive audio and video pro-
cessing capabilities. The foundation of the PIX 250i is hardware-based, 10-bit video up/down/cross
conversion, and hardware-based encoding to Apple ProRes and Avid DNxHD codecs (both up to
12-bit 4:4:4). These features allow for fast, reliable acquisition of video (at any standard HD or SD
resolution and frame rate) and audio (up to 16 tracks from Analog, AES, HDMI, or SDI sources) to
ready-for-edit, industry standard QuickTime .mov files.
Files are recorded simultaneously on (up to) 2 separate, 2.5” SSD storage devices via two front panel
PIX-CADDY slots. This redundancy in local, removable storage devices, coupled with standard,
Ethernet-based file transfer features further reduces steps in the production workflow. Gigabit Ether-
net network ports enable remote access to recorded files and the ability to transfer them quickly into
a post-production environment.
Full-featured precision timecode and sync reference I/O using Ambient Clockit core technology is
provided to allow tight synchronization with external equipment in complex multi-machine configu-
rations. The PIX 250i supports various external control options: RS-422, GPIO, SDI flags, Timecode
triggering, and an embedded web server for network-based remote control. Network Grouping
functionality enables linked, frame-synchronized recording and playback of multiple PIX 250i units
connected to a standard Ethernet network.
This User Guide details installation and operation of the PIX 250i. This User Guide corresponds to
PIX 250i firmware version 2.000. User Guide revisions are released at the same time as firmware
updates and available online:

Manual Conventions
Several formatting features have been included to make navigating the guide easier.
• Physical buttons on the PIX 250i are represented with capital letters (REC button, MENU button,
etc). All physical button names are detailed in the
Panel Descriptions
section.
• Button combinations are represented with the plus (+) symbol. For example: “Press LCD
AUDIO button” means to first hold down the LCD button, then press the AUDIO button, and
finally release both buttons.
• Setup Menu items are indicated with this text:
[Menu Category - Parameter]
, where the menu
category is one of the items in the list displayed when the MENU button is pushed, and the
parameter is an item in the list displayed when that category is selected (by pushing in on the
Control Knob).
• Blue italicized text references sections of the user guide containing contextually relevant informa-
tion. When viewing this document on a computer, this text can be clicked to jump to the named
