PIX 270i User Guide and Technical Information
Introduction
The PIX 270i is a rack-mountable, production video recorder with extensive audio and video processing capabilities. The foundation of the PIX 270i is hardware-based, 10-bit video up/down/cross
conversion, and hardware-based encoding to Apple ProRes and Avid DNxHD codecs. These features
allow for fast, reliable acquisition of video (at any standard HD or SD resolution and frame rate) and
audio (up to 64 tracks from Analog, AES, HDMI, SDI, MADI, or Dante sources) to ready-for-edit,
industry standard QuickTime .mov files.
Files are recorded simultaneously on (up to) 4 separate, 2.5” SSD storage devices via two front panel
PIX-CADDY slots and two rear panel eSATAp connections. This redundancy in local, removable
storage devices, coupled with standard, Ethernet-based file transfer features further reduces steps in
the production workflow. Gigabit Ethernet 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 configurations. The PIX 270i 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 270i units
connected to a standard Ethernet network.
This User Guide details installation and operation of the PIX 270i. This User Guide corresponds to
PIX 270i firmware version 2.10. User Guide revisions are released at the same time as firmware updates and available online:
http://www.sounddevices.com/products/pix270i/downloads/
Manual Conventions
Several formatting features have been included to make navigating the guide easier.
• Physical buttons on the PIX 270i are represented with capital letters (REC button, MENU, 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” means to first hold down LCD, then press AUDIO, 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 MENU is pushed, and the parameter is an
item in the list displayed when that category is selected (by pressing in on the Control Knob).
• Blue italicized text references sections of the user guide containing contextually relevant information. When viewing this document on a computer, this text can be clicked to jump to the named
section.
Video Mode and Audio Mode
Introduction
Throughout this User Guide, the terms Video Mode and Audio Mode will be used. The PIX 270i is
capable of recording video and audio together into a QuickTime .mov file (Video Mode) or recording audio only to a .wav file (Audio Only Mode). The mode is determined by the Setup Menu option
[System - Video/Audio Mode]. When set to [Video + Audio (QuickTime), the PIX 270i is in Video
Mode. When set to Audio Only Poly (Wave) or Audio Only Mono (Wave) the PIX 270i is in Audio
Mode.

PIX 270i User Guide and Technical Information
** Not supported over HDMI
Progressive Segmented Frames (PsF)
Some cameras output video signal in progressive segmented frames (PsF). PsF is a method for
transmitting progressive video in an interlaced stream. A device generates PsF signal by splitting
each frame into two segments. PsF segments are the same as interlaced fields in that one segment
represents the even lines of a frame and the other segment represents the odd lines of a frame. PsF
segments differ from interlaced fields in that there is no motion between each segment in a pair.
The PIX 270i will automatically sense PsF signal from most cameras that output PsF over SDI. This
is accomplished through the use of a flag inserted into the SDI signal by the camera. If a camera does
not insert this flag into the SDI stream or if it outputs PsF signal over HDMI, then the Setup Menu
option [Video - Input PsF Detect] can be set to Interpret 1080i as PsF. This will force the PIX 270i to
treat all 1080i signal as if it were PsF and deinterlace it accordingly.
Selecting a Video Codec
Setup Menu option: [Video - Codec].
The PIX 270i has two families of intra-frame, DCT-based codecs available: Apple ProRes and Avid
DNxHD, with five levels of compression for ProRes and four levels of data compression available for
DNxHD. Both codecs are intermediate codecs that assist the editing process by eliminating the need
to transcode video before importing into Final Cut (ProRes) or Avid (ProRes or DNxHD).
ProRes is a variable data rate codec and DNxHD is a fixed data rate codec. PIX 270i supports all
compression levels and bit rates of ProRes and DNxHD and automatically records the correct bit rate
dependent upon the video input resolutions and frame rate. The data rates indicated in the Setup
Menu item [Video - Codec] indicate the maximum data rate at 1080p30.
DNxHD 36 Mb/s only supports 1080p signal. Standard definition recording is only available for ProRes
422 HQ, ProRes 422, and ProRes 422 Proxy.
Interruption of Signal During Recording
In video mode, in the event that video signal is lost (an unplugged HDMI or SDI cable, for example)
during recording, the PIX 270i will pause the recording and wait for video signal to be re-initialized.
If video signal is re-initialized recording will begin again to a new file of the same name with an
“A” appended to the end. Further interruptions of signal during that take will cause an alphabetic
filename progression (“B”, “C”, etc).
In Audio Mode, loss of video signal will have no affect on the transport state unless the video signal is the
sync reference source.
Alignment of Audio and Video
Recording
An advantage to recording audio on the PIX 270i along with the video is the elimination of audio/
video sync problems in post. The PIX 270i has many options regarding audio sources along with the
two options for video inputs, HDMI and SDI. Given this flexibility, care must still be taken to ensure
good audio/video sync.
27
PIX 270i User Guide and Technical Information
If recording camera audio embedded on HDMI or SDI, then the audio/video alignment will be excellent provided the alignment is proper on the camera.
If recording audio using the dedicated audio inputs (Analog, AES, MADI, or Dante), then a delay
may need to be dialed in. The reason for this is that some cameras have a delay of one or more
frames from lens to SDI/HDMI output. The PIX 270i on the other hand has no appreciable delay
between audio and video. This means that if the camera does have this delay, the audio will lead the
video as recorded by the PIX 270i. Note that on some cameras, the lens-to-SDI/HDMI delay changes
with resolution/frame rate. The best practice is to test the audio/video sync using a clapper slate
on a test file for each camera resolution/frame rate to be used on a project before starting. See Audio
Input Delay Control for details
Audio Track Arming
Up to 64 Tracks of audio can be recorded in both Audio and Video modes. Tracks must be armed in
the Audio Screen in order for them to be recorded. Armed audio tracks will have a red background
in the Arm column. Unarmed audio tracks will have a black background in the Arm column. To arm
or disarm Tracks for recording:
1. Press AUDIO to access the Audio Screen.
2. Rotate the Control Knob to select the desired track.
Recording
3. Press the Control Knob to focus the highlighter on the selected track’s parameters. The high-
lighter will become orange and focus on a single column in the track.
4. Rotate the Control Knob to highlight the Arm column (The Arm column is the left-most column and displays the track number).
5. Press the Control Knob to access the Arm Menu. Turn the Control Knob to select On, Off,
All On, or All Off. (All On and All Off will change the arming status of all tracks, regardless
of which track is selected).
Changing a track’s Input Source to Off will disarm the track.
When [Audio - Audio Mode Sample Rate] is set to 88.2k or 96k, tracks 33-64 are disabled.
Audio Mode
When Setup Menu option [System - Video/Audio Mode] is set to Audio Only Poly (Wave) or
Audio Only Mono (Wave) the PIX 270i is in Audio Mode. In Audio Mode, the PIX 270i records only
audio signal to uncompressed PCM .wav files.
Polyphonic or Monophonic WAV Files
Audio Only Poly (Wave) mode writes a single file to each target drive per take. All armed audio
tracks are interleaved into a single file.
28
Audio Only Mono (Wave) mode writes a file for each armed track to each target drive per take.
Mono files will be named according to [File Storage - File Name Format] with the addition of an
underscore (“_”) character followed by the track number at the end of the file name.
If File Name Format is set to Reel-Scene-Take_Track Name, a WAV mono file will be given names in
the following format: <Reel>-<Scene>-<Take>_<Track #Track Name>.
v. 2.10 Features and specifications are subject to change. Visit www.sounddevices.com for the latest documentation.
PIX 270i User Guide and Technical Information
For example, if Reel=141001, Scene=101A, Take=001, Track=01, and the Track 1 Name is Boom, then
the file’s name would be 14001-101A-001_01Boom.WAV
Mono Wave files can be written to a maximum of 2 SSD’s. Recording Mono Wave files to a mechanical
(spinning) hard drive is not supported.
Poly (Wave) File Format writes a single file to each target drive per take. All armed audio tracks are
interleaved into a single file.
If File Name Format is set to Reel-Scene-Take_Track Name, but WAV poly files are being recorded, the
alternative format of Reel-Scene-Take will be used.
Audio Mode Settings
Certain Setup Menu options apply only to Audio Mode:
• [Timecode/Sync - Sync Ref - Audio Only Mode]: This determines the sync reference source clock
for audio mode. The source can be set to Internal, Word Clock (Sync In), AES1-2, MADI, Video
Input (SDI/HDMI), or Video Ref (Sync In).
After changing the Sync Reference in Audio Mode, allow approximately 10 seconds before recording.
• [Audio - Audio Mode Sample Rate]: This menu option only applies when the
[Timecode/Sync - Sync Ref - Audio Only Mode] is set to Internal. The default sample rate is 48
kHz. When sample rate is set to 88.2k or 96k, tracks 33 to 64 are disabled.
• [Audio - Audio Mode Bit Depth]: The bit depth of recorded audio in Audio Mode. The default Bit
Depth is 24. Audio Mode allows for 16- or 24-bit recordings.
• [Audio Mode - Pre-Roll Time]: In Audio Mode, a continuous audio buer of up to 10 seconds
is maintained. The Pre-Roll Time will be “added” to the front of all audio recordings. Timecode
stamps are automatically adjusted to match the Pre-Roll time.
Changing the armed status of any track, changing the value of Setup Menu option
[Audio - Audio Mode Sample Rate], or changing the current audio synch reference will reset the preroll buffer.
• [File Storage - Wave File Split Every]: The le size that will cause a .wav le split in Audio Mode.
At factory default audio les will automatically split when the le size reaches 4 GB. Audio recordings can also be split when the le size reaches 2 GB.
• [Timecode/Sync - Frame Rate (Audio Only)]: The frame rate that will be stored in the iXML and
Bext area of the .wav le. The default frame rate is 29.97 non-drop. The available frame rate options
are 23.976, 24, 25, 29.97, 29.97 drop-frame, 30, 30 drop-frame.
If the synchronization source (Setup Menu option [Timecode/Sync - Sync Ref -Audio Only Mode])
is lost while in record, the recording will stop. The Sync Reference OSD field will flash
red if the synchronization source is not present. The Audio Input OSD field will flash red if
there is a mismatch between the currently selected audio sync reference sample rate and the
[Audio - Audio Mode Sample Rate] setting.

F Sampling Rate Modes
48.048k and 48.048kF
The 48.048kF mode (F can stand for “fake”, “faux”, or “Fostex”) is a specific compatibility mode for
use with the Fostex DV40 software (1.74 and previous), Avid, Final Cut Pro, and other post-production environments that do not recognize audio files written at 48.048 kHz. In this mode WAV files are
recorded at a 48.048 kHz sampling rate but are stamped at 48 kHz. When played, they will play back
0.1% slower than real time.
One use for the 48.048kF mode is to force a 0.1% speed reduction (pull down) of audio to match
MOS-telecined film (24 fps-to-NTSC) in non-linear edit systems, such as Avid or Final Cut Pro. Since
the file is stamped as a 48 kHz file, the edit system will play it back at 48 kHz and not at 48.048 kHz.
This “audio pull down” will match the transferred picture without the need for an intermediate step
through other software to create the pull down.
The timecode frame rate (actual recording rate) is forced to 30 ND in 48.048kF mode. The audio file,
however, is stamped with a 29.97 ND frame rate, along the 48 kHz sampling rate. It will appear as if
the file was originally recorded at a 48 kHz sampling rate at a TC rate of 29.97 ND.
Fostex DV40
When using files recorded in the 48.048kF mode in with a DV40 with early software, set the DV40
timecode frame rate to 29.97ND. Timecode stamps will properly match the original timecode start
Recording
times.
47.952k and 47.952kF
Both 47.952 and 47.952kF settings use a record sampling rate of 47.952 kHz, 0.1% lower than 48 kHz.
The 47.952kF mode, however, identifies the file as being recorded at 48 kHz. Additionally there are
two frame rate options in 47.952kF mode. The timecode frame rate can be set to 23.97 while the file is
identified as 24ND or it can be set to 29.97ND while the file is identified as 30ND. By default, when
47.952kF mode is selected the frame rate is changed to 29.97ND and identified as 30ND unless the
Frame Rate was already set to 23.97 in which case it will remain at 23.97.

PIX 270i User Guide and Technical Information
Video Scaling and Frame Rate Conversion
The PIX 270i features powerful, hardware-based video scaling, frame rate conversion, and de-interlacing. This allows for converting the resolution and frame rate of input video signal to the recorded
file and to the HDMI and SDI outputs in real-time.
Video scaling and/or de-interlacing is active whenever the Setup Menu option
[Video - File Resolution/Rate] is set to something other than Same as Video Input. Any supported input signal can be converted to any available resolution. When set to record progressive frames, the PIX 270i will convert incoming interlaced video to progressive frame video
via its built-in, powerful, hardware-based de-interlacer. The PIX 270i will also convert progressive segmented frame (PsF) video to progressive video automatically if Setup Menu option
[Video - File Resolution/Rate] is set to a progressive frame format (for example 1080p30). If Setup
Menu option [Video - File Resolution/Rate] is set to interlaced format (for example 1080PsF30), the
PIX 270i will record PsF signal unaltered, but the file will be stamped as interlaced.
Frame rate conversion occurs whenever the frame rate of [Video - File Resolution/Rate] differs
from the frame rate of the input video signal. Frame rate conversion is achieved by appropriately
duplicating or dropping frames. The PIX 270i will auto-sense between integer and non-integer frame
rates (for instance 30 frames vs. 29.97 frames). The PIX 270i will not frame rate convert between
integer and non-integer frame rate values. For example, if the incoming video signal is 1080i59.94,
it can be converted to 1080p29.97 or 720p59.94 but not 1080p30 or 720p60. The Setup Menu option
[Video - File Resolution/Rate] contains entries with a combination of integer and non-integer frame
rates (such as 1080p30/29.97). When any of these options are selected, the PIX 270i will record in the
indicated integer frame rate if the input video is an integer frame rate or record in the indicated noninteger frame rate if the input video is a non-integer frame rate.
Not all frame rate conversions are visually desirable. When the OSD Item File Resolution/Rate is
red, the conversion of the frame rate of the input video will contain a finite amount of motion judder.
For example, if the incoming video is 720p60 and [Video - File Resolution/Rate] is set to 720p50,
the cadence of dropped frames may be noticeable depending on the content. Conversions that are
simply 1:2 or 2:1 (such as 1080i59.94 to 1080p29.97) introduce no motion judder. For these conversions, the OSD Item File Resolution/Rate remains white.
When the input video signal is 720p24 or 720p23.976, up-, down-, and cross-conversion is not available.
3:2 Pulldown Removal
Many cameras which shoot with a shutter speed of 24/23.976 frames per second will output signal
on the HDMI or SDI output at 60i/59.94i. To achieve this, the camera performs a “3:2 pulldown”
process. The 3:2 pulldown process splits each frame into 2 fields and duplicates a field periodically.
The PIX 270i is capable of removing 3:2 pulldown from a 60i/59.94i signal and converting it back to
24/23.976 progressive frames per second in real-time. The PIX 3:2 removal process actively views
video fields looking for duplicates. When these duplicates are sensed, then this cadence is locked in
and the appropriate extra fields are removed. The process depends on motion in the incoming video.
The OSD item File Resolution/Rate changes from orange to white when this cadence is detected:

31
PIX 270i User Guide and Technical Information
It is important that 3:2 pulldown be sensed before beginning a recording. If recording begins before 3:2
pulldown is sensed, 3:2 pulldown will not be applied properly.
Video Scaling and Frame Rate Conversion
Up and Down Conversion
Standard-definition video resolution employs a 4:3 aspect ratio, and high-definition video resolution
employs a 16:9 aspect ratio. Up-conversion is the process of fitting standard-definition video (with a
4:3 aspect ratio) into a high-definition, 16:9 frame. Down-conversion is the opposite process.
Orange: No 3:2 pulldown sensed in 60i/59.94i input signal.
Input video is being converted to 24p/23.976p using a conversion process which drops frames and may introduce judder.
White: 3:2 pulldown sensed in 60i/59.94i input video signal.
Input video signal is being converted to 24p/23.976p using 3:2
pulldown removal which recreates 24p/23.976p as it is captured from the camera’s shutter.
The PIX 270i has various options for up and down conversion:
Down-Conversion
Letterbox: Maintains the same height and width ratio. Results in blank bar at top and bottom of image.
Crop: Left and right side of image is cropped to fit into 4:3. Results in missing image at sides of picture.

PIX 270i User Guide and Technical Information
Playback
The PIX 270i has a very powerful playback engine that allows for playback of QuickTime .mov
files and PCM .wav files whether the files were generated by the PIX 270i or elsewhere (See “Ap-
pendix A - Supported Files”, page 85). Playback video is shown on the onboard LCD display and
is sent to the video outputs. The PIX 270i’s video playback clock is determined by the setting in
[Timecode/Sync - Sync Reference -Video Playback]. Audio Only playback clock is determined by
the setting in [Timecode/Sync - Sync Ref -Audio Only Mode].
Any number of PIX 270i units can be assigned to one of four available network groups for frame
synchronized record and playback of video on multiple units simultaneously (See “Network Group-
ing”, page 47).
Playback Operation
The current Playback drive is indicated by the green Drive Status OSD field. From the Main View,
pressing the Play () button after a recording will play the most recent file. Using the Rewind (<<)
and Fast Forward (>>) buttons, previously recorded files can also be cued for playback. The file cued
up for Playback is displayed in the File Name field of the OSD.
To browse files on the Playback drive, press FILES. This will display the File List of the current Playback drive. Pressing Play () in the File List will play the currently highlighted file.
Playback
To browse files on another drive, scroll beyond the top of the File List to access the drive selection
list. When a file is played, the drive it is played from will become the current Playback drive. When
a new take is recorded, the lowest numbered drive it is written to will become the current Playback
drive.
In Playback Mode the Play () button and the OSD Items ABS Time, Timecode, Filename and
Drive Indicator are green. While in Playback Mode, pause playback by pressing the Play () button
again. The Play button flashes green to indicate playback is paused. Press the Stop () button any
time to stop playback and exit Playback Mode.
Frame-by-frame scrolling (similar to the traditional Jog function) is supported when playing back
QuickTime .mov files. To scroll through a video file frame by frame, pause playback then turn the
Control Knob to increase/decrease the video file in one frame increments.
Various looping playback functions are supported. In Video Mode, a single file or a section of a
file (defined by cue markers) can be continuously looped by entering Looping Playback Mode (See
“Looping Playback”, page 36). Additionally, a list of files can be defined as a Play List and the Play
List can also be looped (See “Play List”, page 37).
Playback audio of both QuickTime .mov and PCM .wav files is routed to audio outputs as determined by output routing options in the [Audio] Setup Menu section. (See “Audio Outputs”, page 18)
Fast Forward and Rewind
Video Mode: Hold down the Fast Forward (>>) or Rewind (<<) button during playback for 2x
(double) speed playback. When the Fast Forward (>>) or Rewind (<<) button is held for five seconds
or more the playback will become 16x speed. Normal playback will resume when the buttons are
released.
34
Audio Mode: Hold down the Fast Forward (>>) or Rewind (<<) button during playback scrub for-
ward or backward. As the Fast Forward (>>) or Rewind (<<) button is held down, playback speed in

PIX 270i User Guide and Technical Information
Synchronization and Timecode
Synchronization of video, audio, and associated timecode while recording video and audio has long
been a problematic area. Situations where several cameras are used can complicate issues further.
There may be sync issues between two (or more) cameras and/or between audio recorders because
of a) offset and b) drift. In a production environment (during recording), offset and drift are both
terms to describe a timing problem between the timecode signal from two or more audio or video recorders. In a post-production environment (a non-linear editor application), offset and drift are both
terms to describe a timing problem between two or more audio or video files.
Offset (matching the beginning or “head” of a take) occurs because the beginning of takes are not
aligned due to the absence or misuse of timecode. Drift (matching the end or “tail” of a take) occurs
because different recorders (audio or camera) run at different rates - the beginning of files from each
may have zero offset, but by the end they drift apart. The PIX 270i was designed with these problems
in mind and includes the most comprehensive and powerful synchronization features available in a
production recorder. These features can be used to alleviate or eliminate offset and drift problems in
both production and post-production. While the PIX 270i’s design makes setting the parameters as
easy as possible, a good understanding of synchronization is still necessary to properly operate the
PIX 270i and ensure a trouble-free workflow.
In a camera, the shutter, video circuitry, audio sampling, and timecode all run off of one “heartbeat”
from its master internal clock. If this master clock is slightly fast, then the shutter, audio sampling,
and timecode will be slightly fast. If the master clock is a slightly slow, the shutter, etc will also be
slightly slow.
When a PIX 270i’s video input is connected via HDMI or SDI to a camera or other video source,
this “heartbeat” is passed through the HDMI or SDI. The PIX 270i video and audio circuitry can be
clocked off of this incoming signal. In other words, the PIX 270i references this clock and synchro-
nizes its own clock to it. The PIX 270i writes files based on this clock as well - each audio sample and
video frame written out to the file is synchronized to the incoming video. This way, the PIX 270i is
always completely in sync with the connected video source - there can never be any drift of audio or
video between the camera and the PIX. (See “Sync Reference”, page 40)
Drift problems in a workflow can arise when more than one camera is used on a shoot, as each camera is driven off of its own internal master clock. Since internal master clock speed will always vary
from camera to camera (and vary based on temperature and time), each camera used will run at a
slightly different shutter speed, audio sample rate, and timecode rate. This is also true when recording video on a camera and recording audio on a separate recorder, as each device has its own internal master clock. Particularly problematic are long takes where there may be significant drift from
camera to camera from the beginning to the end of the take’s file. Even if the heads match, the tails of
a take may not.
These drift problems can be mitigated during recording by using a Genlock (or “Sync”) Input on a
camera which takes over the camera’s internal master clock. Wiring several cameras’ Genlock Inputs
together forces all of the cameras to run at the exact same rate with no drift. This same concept applies to audio recorders using the Word Clock input. Genlock inputs are available only on higher-end
cameras and Word Clock inputs are available on higher-end audio recorders.
Offset problems are easier to overcome than drift problems. By feeding each recording device with
the same timecode signal, the files from different recording devices can all be in sync and there will
be no offset in post-production.
Synchronization & Timecode
The PIX 270i can address the synchronization issues of both offset and drift (heads and tails) via its
built-in Ambient® Lockit with Genlock Out and Timecode Reader. The PIX 270i’s Ambient® Lockit
39
PIX 270i User Guide and Technical Information
features an internal clock which has an accuracy of +/-0.2ppm (½ frame per 24 hours). Numerous
PIX 270i recorders can be used to maintain extremely tight synchronization.

Video Mode Synchronization
Setup Menu option [Timecode/Sync - Sync Ref - Video Playback].
In Video Mode the PIX 270i’s sync source is always the incoming video signal when stopped and
while recording. This is to ensure that the PIX 270i is always in sync with the incoming video source.
During Playback of QuickTime files, the PIX 270i can reference its own Internal clock, Video Input
(SDI/HDMI), or Genlock signal at the SYNC IN BNC.
When [Timecode/Sync - Sync Ref - Video Playback] is set to Video Ref (Sync In), and no valid signal
is present at the SYNC IN connector when playback is initiated, a warning dialog will appear on the
LCD.
When [Timecode/Sync - Sync Ref - Video Playback] is set to Video Input (SDI/HDMI), and the
playback file’s resolution and rate are different than the Video Input, the PIX 270i will automatically
use its Internal clock. The OSD label will flash with red text during playback to indicate that the sync
source is not present.
Audio Mode Synchronization
Setup Menu option [Timecode/Sync - Sync Ref - Audio Only Mode].
In Audio Mode, the audio sync reference source is used for both Record and Playback. Sync reference for Audio Only mode can be the PIX 270i’s own Internal clock, Wordclock (Sync In), AES 1-2,
MADI, Video Input (SDI/HDMI), or Video Ref (Sync In).
The supported sample rates for audio synchronization are those available in the Setup Menu option
[Audio - Audio Mode Sample Rate]. The PIX 270i will only lock to supported sample rates from any
source (including external sources). When an unsupported sample rate is present at the sync reference source, the OSD label will flash red to indicate there is no synchronization occurring.

PIX 270i User Guide and Technical Information
Timecode Reader
The PIX 270i includes a timecode reader which can accept incoming SMPTE timecode. The
PIX 270i can read timecode from embedded SDI/HDMI or linear timecode fed into the
TC IN BNC connector. The timecode reader is enabled whenever the Setup Menu option
[Timecode/Sync - Timecode Mode] is set to any Ext TC mode which indicates that it will read external timecode.
Timecode Reader operation is useful for simple cases where the PIX 270i’s timecode follows the camera timecode. The timecode of the PIX 270i’s file will match exactly with the camera’s file with zerodrift since the PIX 270i is always synchronized with video input during recording in Video Mode. see
Video Mode Synchronization).
In situations where a consistent offset is observed between PIX 270i files and other production recordings, the PIX 270i can offset the timecode stamp on each file. The Setup Menu option
[Timecode/Sync - File Start TC Offset] allows for adjustment of the frame offset from -10 to +10 in
increments of 1 frame. This setting does not affect timecode on the PIX 270i’s outputs.
For shoots involving more than one camera or an audio recorder, using the PIX 270i’s Timecode Generator can be more beneficial than using the Timecode Reader to achieve good heads and tails sync
between all recordings.
Internal Ambient® Lockit: Timecode Generator with Sync Out
The PIX 270i includes an internal Ambient® ACL-203 Lockit which can be used as a master sync/
timecode source for cameras or audio recorders. The Lockit is an ultra-high accuracy sync/timecode
generator with < 0.2 ppm (½ frame per 24 hours) accuracy that is suitable as a master clock in all
levels of productions. With its internal, rechargeable battery, accurate timecode is maintained for up
to 4 hours after the PIX 270i is powered down. After 4 hours, the timecode value is reset. The battery
is recharged automatically.
Multi-camera shoots using cameras that accept genlock input can benefit from the PIX 270i’s built-in
Ambient® Lockit as their master sync and timecode source. Files from multiple PIX 270i recorders
will have very tightly synchronized recordings with matching heads and tails.
Additionally, even multi-camera shoots utilizing lower-cost cameras (with no genlock or timecode)
can benefit from the built-in Lockit. By using the Timecode Generator to stamp the beginning of each
file, the heads of each take will match from several recorders, even if the tails drift due to using nongenlocked cameras.
Setting the Sync Out
The setting of this is parameter is found in Setup Menu option [Timecode/Sync - Sync Out]. When
the Sync Out of the PIX 270i is not needed, set this option to Off. When using the Lockit to generate the Sync (genlock) for a camera, the frame rate and resolution must be set for the camera’s sync
input. Consult the camera’s documentation for information of which rates are accepted.
Additionally, there are two advanced modes under [Timecode/Sync - Sync Out]:
Genlock, Follows Video In and Wordclock, Follows Video In. Genlock, Follows Video In can be
used to slave another camera or audio recorder’s genlock input to the camera feeding the PIX. Likewise, Wordclock, Follows Video In can be used to slave an external audio recorder to the camera
driving the PIX to achieve perfect audio sync with zero drift. Drift is less likely to be an issue when
recordings are kept short.
Synchronization & Timecode
It is not possible to pass the Sync Input signal to the Sync Output (this is not a loopthrough).

PIX 270i User Guide and Technical Information
Timecode Modes
Freerun Timecode Mode
Generator mode. Timecode runs continuously. The value can be set by “jamming value” in the Setup
Menu option [Timecode/Sync - Jam Received TC] or by manually setting a value from the Setup
Menu option [Timecode/Sync - Set Generator TC].
Freerun Auto Mute
Functions the same as Freerun mode except timecode signal is muted from the timecode output
when the PIX 270i is in Stopped mode. This allows rec-run functionality when Rec Run mode is not
suitable (e.g. Multi-camera shoots).
Record Run Timecode Mode
Generator mode. The PIX 270i sends running timecode while recording and stationary timecode
while not recording. Timecode in this mode defaults to the last stationary value at power-up. When
switching to Record Run from another mode, the internal generator will stop at the last number gen-
Synchronization & Timecode
erated. A user-defined value can be jammed into the internal generator from the Setup Menu option
[Timecode/Sync - Set Generator TC].
24 Hour Run Timecode Mode
Generator mode. Timecode runs continuously. When this Time Code Mode is selected or when the
time/date is altered, the timecode value is jammed to the value of the time-of-day clock. The value
can be set by “jamming value” in the Setup Menu options [TIMECODE/SYNC - Jam Received TC] or
[TIMECODE/SYNC - Jam Time Of Day]. The value can also be set manually from Setup Menu option
[TIMECODE/SYNC - Set Generator TC].
24h Run Auto Mute
Functions the same as 24h Run mode except timecode signal is muted from the timeocde output
when the PIX 270i is in Stopped mode. This allows rec-run functionality when Rec Run mode is not
suitable (e.g. Multi-camera shoots).
External Timecode Mode
Reader mode. The PIX 270i’s internal timecode generator follows an external timecode signal appearing at the BNC Timecode Input, timecode embedded on the SDI or HDMI input (See “SDI or
HDMI Input Embedded Timecode”, page 43). If the external timecode is removed the internal genera-
tor continues to run to preserve continuous timecode.
External Timecode Halt Mode
Reader mode. Identical to normal External Timecode mode, except that when external timecode
is removed (signal is lost), the internal timecode does not continue. When Setup Menu option
[Remote Control - Rec Start/Stop] is set to Timecode, this mode will cause the PIX 270i to stop
recording when timecode signal is disconnected or invalid (In addition to stopping when stationary
timecode is received).
42
Timecode Frame Rate
When using external timecode and the incoming frame rate does not match the frame rate as set in
Video - File Resolution/Rate, the timecode frame rate display will appear orange to notify the user.
The PIX will still record using the File Resolution/Rate.

PIX 270i User Guide and Technical Information
Timecode Input Sources
Timecode BNC
The Timecode Input BNC accepts standard SMPTE timecode signal.
SDI or HDMI Input Embedded Timecode
The PIX 270i can use timecode embedded in the SDI or HDMI (Sony) input signal.
[Timecode/Sync - Timecode Mode] must be set to Ext TC (SDI, HDMI).
Synchronization/Timecode Examples
The following examples illustrate common scenarios where timecode and synchronization can be
employed with the PIX 270i and other devices.
Single Video Camera, no Genlock
SDI/HDMI
In this scenario, the video camera is the master source of the video sync. The timecode can either be
read from the camera or be generated by the PIX 270i. The accuracy of the recording is dependent on
the internal clock accuracy of the camera.
To receive timecode from the camera, set [Timecode/Sync - Timecode Mode] to one of the external
timecode modes for cameras that output standard SMPTE timecode to the PIX 270i’s Timecode BNC.
Alternatively, the PIX 270i can receive timecode from the SDI or HDMI input (if the camera sends
timecode in this way) by setting [Timecode/Sync - Timecode Mode] to Ext TC (SDI, HDMI).
The Setup Menu option [Timecode/Sync - Sync Out] can be set to several valid settings, including
the following:
• Off - sync signal is disabled.
• Genlock, Follows Video In - Genlock for another camera or device is derived from the video sig-
nal of the single camera.
• Wordclock, Follows Video In - Wordclock for an audio device is derived from the video signal of
the single camera.

and be assured of frame-accurate sync with no possibility of drift.
Set the output of the sync generator to a selected rate and connect the PIX 270i Sync Out (Genlock)
and timecode output to multiple cameras (“mult” the genlock output). This connection uses the PIX
270i as both the video sync source and timecode source. Heads and tails sync for the camera and PIX
files will be perfect.

PIX 270i User Guide and Technical Information
Powering
The PIX 270i features an advanced powering system with 2 redundant DC Inputs (on rear XLR4M
connections) and PowerSafe technology. Two power sources can be attached simultaneously. When
multiple power sources are connected, the PIX 270i will use only one source at a time. The order of
precedence for power sources is:
1. DC Input 1 (Primary power source)
2. DC Input 2 (Secondary power source)
3. PowerSafe circuitry (Shutdown)
By default, the PIX 270i will operate from the Primary power source. When the Primary power
source is removed (or its voltage drops below 9V), the PIX 270i switches to the Secondary power
source without interruption, if available. When operating from the Secondary power source, if the
Primary power source voltage rises above 10.5V, the PIX 270i switches to the Primary power source
without interruption.
Synchronization & Timecode
PowerSafe
When power is removed or voltage drops below the threshold and no Secondary power source is
available, PowerSafe circuitry will activate. The PIX 270i displays a warning, stop any active recordings, finish writing files, and shut the PIX 270i down. The PowerSafe Battery will power the PIX 270i
during this time. This feature ensures that files will be protected even in the event of unexpected
power loss.

PIX 270i User Guide and Technical Information
Network Grouping
When multiple rack-mounted PIX video recorders (PIX 250i, PIX 260i, or PIX 270i) or the 970 Audio
Recorder are in use on an Ethernet network, they can be grouped together for transport control and
linking of most setup options. Setup Menu option [Network - Grouping - Network Group] assigns
the PIX 270i to one of four available groups.
In this section, the term “unit” refers to PIX 250i, PIX 260i, or PIX 270i Video Recorders, or the 970
Audio Recorder, unless otherwise specified.
There is no “master”/“slave” relationship in Network Groups. All units in a group are “master”.
Transport commands and settings changes made on any unit in a group will ripple to all other units
in the group. If a transport command or settings change has to be made to only one unit in a group,
the unit must be temporarily removed from the group before making the change. To quickly toggle
between No Group and the current group setting, press MENU + Control Knob.
Requirements and considerations when setting up Network Groups:
• The maximum number of units supported in a single group is currently 10. Increasing the amount
of units in a group increases the time of response for grouped transport commands and auto-conguration.
• It is recommended that timecode be distributed individually to each unit in a group rather than
“daisy-chained” through units in a group.
• Allow all units in a group to auto-congure before proceeding with grouped operations. See the
following section for details. (See “Group Auto-Conguration”, page 48)
• For frame-synchronized recording, Setup Menu option [Video - File Resolution/Rate] must be set
to Same as Video Input on all units in the group. (See “Grouped Transport”, page 47)
• For frame-synchronized recording, video input signal to all units in the group must be of the same
resolution and frame rate. (See “Grouped Transport”, page 47)
• Shule, Fast Forward, and Rewind functions are linked, however frame-synchronization is not
guaranteed while these functions are occurring. Frame synchronization will resume when returning to Playback/Pause mode. Normal (1x) playback, Pause, and Jog will always be frame synchronized. (See “Grouped Transport”, page 47)
• Frame-synchronous recording and playback is possible on the PIX 260i and PIX 270i only. Although transport commands are transmied to PIX 250i units in a group, recording and playback
on PIX 250i units is not frame-synchronized.
• Some seings are not linked even when units are in the same group. (See “Grouped Seings”, page
47)
Network Grouping
Grouped Settings
A settings change of any unit in the group will be rippled through to all other units in the group,
with some exceptions. The following settings and functions will always apply only to the unit that
they are made on, and not ripple through to other units in the group (or be pushed when Setup
Menu option [Network - Grouping - Push Settings to Group] is used):
• All [Network] options.
• All [Quick Setup] options.
• [File Storage - Erase/Re-format]
• [Timecode/Sync - Timecode Mode]
• [Timecode/Sync - Jam Received TC]
• [Timecode/Sync - Jam Time of Day]
• [Timecode/Sync - Set Generator TC]
• [Timecode/Sync - Set Generator UBits]
• [System - Set Date/Time]
• [System - Update Software]
47
PIX 270i User Guide and Technical Information
Pushing Settings to Group
When a unit is assigned to a group, none of its settings are immediately changed. Subsequent settings changes to any unit in the group will be applied to all units in the group. To
copy all settings from one unit to the rest of the units in the group, access Setup Menu option
[Network - Grouping - Push settings to group]. This will copy all grouped settings to all other units
in the group.
Group Auto-Configuration
When changes are made to a Network Group, all units in the group must auto-configure. It is important to allow all units in the group to complete auto-configuration before proceeding with any
grouped operations (Transport control, settings changes, etc). While configuring, units will display
a dialog message: Configuring Network: Please Wait... Wait 10 seconds after this dialog has cleared
before proceeding with grouped operations.
Common tasks that will cause a group to auto-reconfigure:
• A unit on the LAN is powered on or o.
• A unit is connected or disconnected from the LAN.
Network Grouping
• A unit is added or removed from a group via [Network - Network Group].
Grouped Transport
Transport control (Record, Play, Pause, Stop, Jog, Shuttle, Fast Forward, and Rewind) of grouped
units is linked. Recording and playback is frame-synchronized among PIX 260i and PIX 270i units
in a group. When a file is selected for playback, all units in the group will play the file of that same
name if it exists. If no file of that name exists, grouped units will play the most recently played or
recorded file.
Adding and removing cue markers, jumping to cue markers, and looped playback is not supported
in grouped units. These features can be effectively used in a grouped unit setup; However, manual
setup on each unit in the group is required. Following are step-by-step instructions to using these
features with grouped units. Failure to comply with these recommendations can result in undesired
behavior if any one of these features is in use while units are grouped. This could include:
• Out-of-sync playback between grouped units
• Some units in the group dropping out of playback prematurely
• Some units playing back the wrong le
• Sluggish transport control response time
To effectively use Loop Play Mode with grouped units:
1. Press and hold Play until the OSD reads LOOP.
2. Repeat step 1 on all units in the group. Now when a clip is looped, the units will remain in
sync.
48
To effectively use Cue Markers with grouped units:
1. Playback a le.
2. Find the spot in the le in which a cue marker is to be placed.
3. Pause Playback.
4. Press FILES + Fast Forward to lay a cue marker.

PIX 270i User Guide and Technical Information
5. Repeat step 4 for all units in the group. Now when jumping to a cue marker on one unit all
units in the group will also jump to the cue point and remain in sync.
To loop between cue points on grouped units:
1. With Loop Mode on and Cue Markers all set, locate the cue point in which the loop will
begin.
2. Press Play + Fast Forward to change the Loop behavior from Loop Clip to Loop Segment
mode. The OSD will display the loop points (for example Cue 1 - Cue 2).
3. Repeat step 2 on all units in the group. All units in the group will now loop between the
selected cue points and remain in sync.

Triggering Recording from External Timecode
The PIX 270i can be configured to start recordings when incoming timecode begins rolling and stop
when it becomes stationary. This is generally referred to as Record Run timecode. The master timecode device should be setup in this manner. To configure the PIX 270i to follow Record Run commands:
1. Set Setup Menu option [Remote Control - Rec Start/Stop] to Timecode.
2. Make sure that the device that is sending timecode is congured to send stationary
timecode while stopped and running timecode while recording. To cause the PIX 270i
to stop recording when linear timecode signal is absent (disconnected), set Setup Menu option
[Timecode/Sync - Timecode Mode] to Ext TC (LTC Halt).
3. Some cameras do not send the correct timecode in the rst few seconds of a recording, or
they send short bursts of timecode causing the PIX 270i to record short unintentional les or
incorrect timecode values. The [Timecode/Sync - Auto Record Hold Off] feature is designed
to eliminate these issues. When a hold o value is applied, the PIX 270i will begin capturing
the moment timecode begins rolling but will only go into record if a valid timecode signal is
present after the hold o time has elapsed.

Storage and File Management
Storage
The PIX 270i records on up to four separate storage devices simultaneously. There are two PIX-CADDY slots on the front panel that are accessed by pulling the LCD Handle forward and tilting the LCD
down. Additionally, there are two eSATAp connections on the rear panel. The four drive connections
are numbered 1 to 4. Functions on the PIX 270i will refer to the drives using these numbers.
PIX-CADDY 2 and PIX-CADDY CF
Drives 1 and 2 are PIX-CADDY slots behind the LCD on the Front panel.
The PIX-CADDY 2 and PIX-CADDY CF allow for simple, quick, and solid connection and removal
of drives for file storage and exchange. When connected to a PIX 270i, whether powered on or off,
the caddy’s USB 3.0 and FireWire 800 connections are disabled. When the caddy is removed, it operates as a high-speed data interface for transferring files from the drive to a computer. Only one data
connection can be used at a time. See PIX-CADDY 2 documentation for details on attaching a 2.5”
drive to the PIX-CADDY.
The PIX-CADDY CF supports CF cards instead of 2.5” drives. It functions the same as the PIX-CADDY except that it does not support Video or Mono WAV File recording.
eSATA
Drives 3 and 4 are eSATAp connections on the Rear panel. These connections can be used to power
an external drive via 5V eSATAp, or they can be used with powered external enclosures using an
eSATA (non-powered) cable. It is important to use an approved drive and external enclosure to ensure proper performance. An up-to-date list of supported storage devices can be found online: http://
www.sounddevices.com/approved
Supported Storage Devices
Sound Devices maintains a list of storage devices that are approved for use with the PIX 270i. An upto-date list of supported storage devices can be found online: http://www.sounddevices.com/approved
Approved mechanical drives are recommended for use only in stationary applications. Excessive vibration
or motion may cause data corruption when using mechanical drives.
The PIX 270i formats and writes to an exFAT filesystem. The exFAT filesystem is readable and writable by Mac OS X, Windows 8, Windows 7, and Windows Vista. Files stored in an exFAT filesystem
are not restricted to 4GB, unlike FAT32 (a commonly utilized filesystem in other digital recorders).
Storage devices to be used with the PIX 270i must be formatted by the PIX 270i.
Drives formatted to UDF with earlier versions of PIX firmware can still be used in the current PIX 270i.
Storage & File Management
Windows XP is not compatible with exFAT volumes by default. The Microsoft update KB955704
(http://www.microsoft.com/en-us/download/details.aspx?id=19364) will allow Windows XP to read and
write to exFAT volumes.
59
PIX 270i User Guide and Technical Information
Mac OSX 10.6.4 and below does not support exFAT volumes.
Formatting
To format a drive:
1. Make sure the drive to be formaed is connected to the recorder and note which drive num-
ber it is.
2. Open Setup Menu option [File Storage - Erase/Re-format].
3. Choose the Erase/Re-format: Drive Number for the drive to be formaed or
Erase/Re-format: All Drives option.
4. A conrmation dialog will appear: “All data will be erased. Continue?”. Use the Control

will be suxed with a dash and drive number to distinguish between drives.
Drive Modes
Each of the four drive slots can be set to Read Only, Record,
Ethernet File Transfer, or Switch to Network upon Full from the Setup Menu option
[File Storage - Drive Record/Network Mode].
• Read Only: Drives in this mode will not be written to during recording. Any compatible files on
the drive will still be available for playback and the drive can still be formatted.
• Record: Drives in this mode will be written to for recording. This is the default mode.
• Ethernet File Transfer: Drives in this mode will be shared to the network as a standard Samba
share (see Ethernet File Transfer) and cannot be recorded to, formatted, or accessed for playback
from the unit.
• Switch to Network upon Full: Drives in this mode will be in Record mode until they are filled.
Once filled, they will be put into Ethernet File Transfer mode.
When [File Storage - Video Record Mode] is set to Simultaneous, a drive that becomes full will
only mount as a network share when the last drive that is set to Switch to Network upon Full becomes
full.
Record Mode (Simultaneous or Sequential)
The Setup Menu option [File Storage - Video Record Mode] determines how drives will be written
to during recording. When set to Simultaneous (the default setting), all drives that are online and set
to Record will be written to at the same time.
60
When set to Sequential (available in Video Mode only), the lowest numbered drive that is online
and set to Record mode will be written to. When that drive is full the recording will continue on the
next available drive that is online and set to Record mode. If no drive is available, recording will
stop. The order of drives when recording sequentially is from lowest (Drive 1) to highest (Drive 4).

PIX 270i User Guide and Technical Information
Metadata
Several parameters can be set within the Setup Menu File Storage to aid in the organization of files.
Some of this metadata can be used in naming the file which is to be recorded. Folders are created on
the drives based on the Reel number. QuickTime files contain reel and timecode metadata.
Broadcast Wave files contain bEXT and iXML chunks that store various metadata information such
as timecode, scene, take, notes, and audio track names. WAV file scene, take, and notes metadata can
be edited on the PIX 270i, from the Take Details Screen (See “Take Details Screen”, page 10) or the
Metadata Screen (See “Metadata Screen”, page 11).
PIX recorders support SMPTE-315M camera positioning metadata for ProRes recordings, but DNxHD
files generated by the recorders will not contain SMPTE-315M metadata.
CamID
The CamID field consists of a single alpha character. It is intended to indicate which physical camera
shot the content for the take.
Reel
The reel can be considered a container for all assets generated during a recording session or day’s work. It is intended
to indicate what reel the recording is part of. The PIX 270i
will create a folder at the root level for each Reel. Recorded
files are placed inside the current Reel folder. This value is
alpha-numeric.
Clip
The Clip field consists of a numeric value between 1 and 999.
It is intended to indicate what clip number the recording is. This field can be set manually and will
increment each time a new file is recorded. The Clip number will reset to 1 when the Reel number is
changed.
Scene/Shot
The Scene/Shot field consists of an alpha-numeric value. Use this field to indicate a descriptive name
for the current scene or shot.
To quickly increment the Scene/Shot value, press Stop + Fast Forward from the
Main View. How the Scene/Shot value increments depends on the current setting of
[File Storage - Scene Increment Mode]:
Numeric: (Default) If the current Scene/Shot value does not have a number on the end, the number 1
will be appended. Otherwise, the last number will be incremented by 1.
Character: If the current Scene/Shot value does not have an alpha character on the end, the letter “A” will be appended. Otherwise, the last letter will be incremented alphabetically. If the final
character is “Z” it will be changed to “A” and - if an alpha character precedes it - that character will
be incremented alphabetically; Otherwise a preceding “A” will be added so that the resulting Scene/
Shot value ends in “AA”.
Off: Scene Increment shortcut will have no effect.

the USB 3.0 connection must be used; not both.
Sound Devices recommends first copying files from the drive to the computer and then editing the
files. It is not recommended to edit files directly off of the drive.
Do not copy unsupported files from a computer (or any other host device) to a drive that is intended to be
used by the PIX 270i. If this occurs, it is advisable to format the drive with the PIX 270i before making
new recordings. See Appendix A for currently supported files
Ethernet File Transfer (Samba)
Samba is an industry standard networking protocol that enables files to be transferred between
the PIX 270i and any device with access to the network (A computer running Mac OSX, Windows,
or Linux for example). Ethernet File Transfer can be initiated remotely via PIXNET (web browser
interface). Ethernet supports data rates up to a theoretical maximum of 1Gbps. In reality, data transfer speeds over Ethernet are dependent on network traffic and many other factors. To transfer files
between the PIX 270i and another network device:
66
1. Aach an Ethernet cable from either PIX 270i Ethernet port to a computer or a LAN (Local
Area Network) connection.
2. Enter Setup Menu [File Storage - Drive Record/Network Mode] to access the Record/Net-
work mode menu for all drives.
v. 2.10 Features and specifications are subject to change. Visit www.sounddevices.com for the latest documentation.
PIX 270i User Guide and Technical Information
3. Select the drive to be mounted and set its mode to Ethernet File Transfer. This drive is now
aached to the Network and unavailable to the PIX 270i for read or write actions. The Drive
Status eld on the OSD will read “Network” in this mode.
4. Now the drive is ready to be accessed via the network. The IP address to use
for network access to the PIX 270i is shown on the OSD and in Setup Menu
[Network - IP Address]. The user name and password are congured from Setup Menu op-
tion [Network - Authentication].
• Mac OSX: From the Finder, select Go > Connect to Server. Enter the PIX 270i address as
“smb://[IP Address]” then click Connect. Enter the user name and password.
• Windows: Click the Start buon (or press the Windows key on the keyboard). In the
search box, enter the PIX 270i address as “\\[IP Address]”. Enter the user name and pass-
word.
5. Drives that are in Ethernet File Transfer mode will appear as folders in the mounted volume
on the computer. When no drives are set to Ethernet File Transfer mode, a folder titled “No_
Drives_Aached” will appear instead.
6. Set the drive’s mode to Record to remove it from the network and make it available for
recording and playback on the PIX 270i. Allow time for the drives to remount before Recording or Playing back les. The Drive Status OSD eld will return to white when the drives are
ready.
FileSafe Utility and the Sound Devices File Format
During recording, PIX recorders store data in a temporary file format with the extension .sdv (for
video) or .sda (for audio). When the recording is completed, the file is converted to its standard
respective format (.mov or .wav). In the event of unintended drive removal or power loss during
recording, these files can be recovered by the PIX recorder itself or with the FileSafe software utility. Upon powering up, the PIX recorder will search all connected drives for .sdv and .sda files and
convert them to their respective .mov or .wav format.
Storage & File Management
The FileSafe utility (currently available for Windows OS) can be used to recover .sda and .sdv files in
the absence of a PIX recorder.
