PIX 220i and PIX 240i Video Recorder User Guide
Introduction
The PIX 220i and PIX 240i are highly advanced video recorders which can record digital video signals from SDI or HDMI sources to an internal 2.5” drive or CompactFlash (CF) card. These recorders
can also record very high quality audio simultaneously with the video to industry-standard QuickTime (.mov) files. QuickTime files can be edited with all major video editing programs.
The PIX recorders compress the incoming video signals using the popular Apple ProRes or Avid
DNxHD codecs at up to 12 bit, 4:4:4 sampling. Both codecs offer excellent video quality in a “ready
to edit” file, not requiring transcoding while importing video.
The PIX 240i features both SDI and HDMI inputs and outputs. The PIX 220i has HDMI input and
output only. The PIX 240i offers a full built-in Ambient® Lockit Timecode Generator/Reader, AES/
EBU audio inputs, and provisions to connect to an external, stand-alone eSATA hard drive.

PIX 220i and PIX 240i Video Recorder User Guide
Powering
The PIX 220i and PIX 240i are powered from either removable, Li-ion rechargeable batteries or
external DC. One or two removable 7.2 V Li-ion batteries can be mounted to the recorder and used
as either primary or backup power. The PIX automatically chooses the power source based on the
voltage level of the external power supply. If the external voltage falls below the level of attached Liion batteries, the unit will transition to Li-ion power. The transition between external and removable
battery powering is seamless and has no affect on recording or playback operation.
In the event that power is lost or media is disconnected during recording, the PIX recorder will recover
the file upon the next power up or drive insertion. Up to 30 seconds will be lost from the end of the recording. (See “Power Loss During Recording”, page 31)
Removable Li-Ion Batteries
PIX recorders are compatible with Sony L-Series Li-ion rechargeable batteries. Several power capacities are available in this battery type, ranging from 1000 mAh to 7000 mAh. Larger amp-hour batteries provide more run-time.
One or two L-Series batteries can be attached to the rear panel. When two batteries are attached, they
operate in parallel. A second battery increases run time and both batteries will drain evenly. Batteries
can be hot-swapped for continuous recording.
CAUTION
Danger of explosion if the battery is incorrectly replaced. Replace only with the same or equivalent type. Properly recycle
batteries. Do not crush, disassemble, incinerate, dispose in a fire or expose to high temperatures.
When powered by the removable Li-ion battery, the LCD displays the battery voltage of each battery.
The nominal operating voltage for Li-ion batteries is 7.2 V, with operating voltages ranging between
6.8–8.5 V. When the total voltage drops to 6.9 V, the voltage display on the LCD will begin flashing
red and the power LED will also flash red to warn that the battery is nearly depleted. When the voltage reaches 6.8 volts the recorder powers down—any recording in-process will automatically close
(stop).
Powering
CAUTION
The XL-WPH3 power supply must be connected to a protective earthing connection in order to ensure safety. The power
supply’s cord acts as the disconnect device. The cord must be readily accessible and remain readily operable.
11
PIX 220i and PIX 240i Video Recorder User Guide
Li-Ion Battery Charging
When power is supplied to the PIX recorder on pins 1, 2 (-), and pins 3, 4 (+) of the External DC
Input and the PIX recorder is powered off, the recorder will charge attached Li-ion batteries. The
included XL-WPH3 power supply will charge Li-ion batteries when the recorder is powered down.
The optional XL-AB accessory cable can be used to power a PIX recorder from an Anton Bauer D-Tap
connector. The XL-AB will not charge attached Li-ion batteries. Make certain that the Anton Bauer
battery can supply enough power for both camera and the PIX recorder.

PIX 220i and PIX 240i Video Recorder User Guide
Video Inputs and Outputs
Video Inputs
The PIX 240i accepts SDI or HDMI video; the PIX 220i only accepts HDMI video. Both recorders will
accept either high-denition or standard-denition rates.
PIX recorders do not accept analog video signals. See the specifications section for a complete list of supported frame rates.
HDMI
The PIX 220i and PIX 240i accept HDMI version 1.4a video and audio. Supported video resolutions
and rates are listed in the specications section. PIX recorders accept up to 10 bit, 4:4:4 video over
HDMI. Two-channel digital audio embedded in the HDMI stream (32 kHz – 192 kHz) is always resampled to 48 kHz when connected to a PIX recorder.
720p30/29.97, 720p25, and 720p24/23.976 are not supported on the HDMI input or the HDMI output.
HDCP copy protection prevents direct digital-to-digital copying of copyrighted material. Protected
DVDs, Blue-Rays and streaming content with HDCP encryption is not valid content and will be ignored
by the PIX recorder.
SDI
The SDI input on the PIX 240i accepts video with embedded audio (up to eight channels) and embedded SMPTE timecode. This connection accepts digital video up to 12-bit, with up to 4:4:4 color
sampling. Unlike the HDMI interface, which auto-negotiates rates between devices, what comes out
of a camera’s SDI output is received by the PIX recorder with no auto-negotiation or sample rate
conversion. The PIX 240i supports 3G-SDI single link, but not dual-link HD-SDI.
Timecode over SDI is not available when recording in standard definition
Video Outputs
The video outputs on the PIX recorders contain incoming video when idle and while recording;
during playback they contain the playback video. Both HDMI and SDI outputs are active simultaneously on the PIX 240i. This allows for conversion from SDI-to-HDMI and HDMI-to-SDI. The
video stream contains embedded audio (up to eight tracks) as dened by the Setup Menu option
Audio Audio Input. Both the SDI and HDMI outputs contain the same embedded audio.
Except during playback, the resolution and frame rate of the output stream is congured in the
Setup Menu option Video File Resolution/Rate. During playback, the resolution and frame rate of
the output stream is determined by the playing video le.
Video Inputs & Outputs
The HDMI outputs of the PIX recorder use the HDMI 1.3a protocol. HDMI output signal is always
10-bit, 4:2:2.
17
PIX 220i and PIX 240i Video Recorder User Guide
Embedded SMPTE timecode and record start and stop ags are included on the SDI output of the
PIX 240i. SDI output signal can be either 10-bit 4:2:2 (YCbCr) or 12-bit 4:4:4 (YCbCr ) as dened by
Setup Menu option Video SDI Output Type.
Timecode Overlay
For monitoring purposes, the timecode value and transport status of the PIX 240i can be visually
overlaid onto video output signal. The overlaid timecode value is displayed in the lower-left corner
of the video signal whenever video output is active. The color of the Timecode Overlay text will
change depending on the transport state of the PIX 240i: White=stop, Green=playback, Red=record.
Access Setup Menu option Video Video Out TC Overlay to enable Timecode Overlay on SDI,
HDMI, or both video outputs.

v. 3.52 Features and specifications are subject to change. Visit www.sounddevices.com for the latest documentation.
PIX 220i and PIX 240i Video Recorder User Guide
Audio Inputs
The PIX recorders accept either two analog audio inputs on XLR connectors or two channels of
embedded audio on the HDMI input. The PIX 240i also accepts up to 8 channels of embedded audio
on the SDI input and the analog XLR inputs can be switched to accept four channels (two streams) of
AES/EBU digital audio.
Analog Audio Inputs
PIX recorders have two high-performance analog audio inputs. These balanced inputs accept either
mic- or line-level signals, and include high-pass lters, limiters, 48V phantom power, linking, and
M/S matrixing.
Input Low-cut Filters
Setup Menu options: Audio Analog 1 Low cut and Audio Analog 2 Low cut.
Low-cut lters on analog inputs reduce sensitivity to low frequency signals (such as wind noise
from a microphone). Signals below the selected frequency are aenuated. The amount of aenuation
increases at lower frequencies according to the slope of the low-cut lter. The Setup Menu option
Audio Low cut Slope allows adjustment of the slope for both analog inputs.
Input Limiters
Setup Menu option: Audio Input Limiter (1,2).
Analog inputs incorporate an advanced, analog/DSP-controlled hybrid limiter to prevent input over-
load. In normal operation and with proper gain seings, the limiters should rarely engage. When
activated, limiters prevent unusually high input signal levels from overloading the analog input
stage of the preamp.
Limiting activity is indicated by a yellow segment on the audio meters (both in the Audio View and
the Main View). When the yellow segment is visible, limiting is occurring. The Input Limiters are ac-
tive for both mic- and line-level inputs. When inputs are linked, the limiters are linked.
Input Polarity
Setup Menu options: Audio Analog 1 Polarity and Audio Analog 2 Polarity.
Input Polarity inversion (sometimes referred as phase reverse) can be applied to either analog input.
This can be used to rectify incorrectly wired balanced cables, to prevent signal cancellation when a
source is dual-miked from opposite directions, or reverse left/right with MS microphone congurations.
Digital Audio Inputs
The PIX 220i and PIX 240i accept digital audio from HDMI. Additionally, the PIX 240i accepts digital
audio input over SDI and AES/EBU inputs. All audio is sampled at 48 kHz.
Audio Inputs
HDMI / SDI Embedded Audio
The PIX 220i and PIX 240i accept two channels of embedded digital audio on the HDMI Video Input.
The PIX 240i accepts up to 8 channels of digital audio on its SDI input.

The PIX 240i accepts AES3 (AES/EBU) digital signals with sampling rates from 32 kHz up to 192 kHz
and bit depths up to 24-bits. Files recorded by the PIX 240i are uncompressed 24 bit, with sampling

rates of 48 kHz. All digital signals connected to PIX are sampling rate converted to 48 kHz, including
signals sent at 48 kHz.
Input Linking
Setup Menu option: Audio Input Linking
Inputs 1-2 can be linked together so that a gain adjustment to one channel will also aect the other
(See “Input Level Control”, page 21). When inputs 1-2 are linked, the limiters are also linked. 48V
phantom power, analog low-cut, and analog polarity seings are set independently for each channel,
even when inputs are linked.
Linked inputs are useful when the PIX is receiving a left/right stereo signal on inputs 1 and 2. Examples include stereo program from an external mixer, stereo program from a camera, and micro-
phones oriented in a stereo conguration.
M/S Matrixing
Mid-side (MS) matrixing is a method for processing audio signal from a cardioid microphone and a
bidirectional microphone into a stereo signal. The cardioid microphone is the “mid” signal and connects to input 1, and the bidirectional microphone is the “side” signal and connects to input 2. The
cardioid microphone is pointed at the sound source, and the bidirectional microphone is oriented
sideways (positioned with its capsule as near as possible to the cardioid microphone’s capsule). the
following diagram shows the relative polar paerns of microphones in an M/S conguration.

Mid Signal
Side Signal
To produce a stereo signal from an M/S conguration, the signal from both microphones must be
processed. The PIX recorder can perform this processing on inputs 1 and 2 when Setup Menu option
Audio Input Linking is set to 1-2MS.
Choosing Audio Sources
The PIX recorders are capable of recording audio from the two analog audio inputs or digital sources
(AES3 or video input). The Setup Menu option Audio Audio Input provides the following options
for audio sources:
