PIX-LR Audio Interface
Front Panel
The PIX-LR is an accessory that provides
the PIX-E Series with two XLR inputs, two
XLR outputs, accurate LED metering, and
dedicated transport and gain controls.
The mic preamps within the PIX-LR are
some of the highest-quality preamps
available, and the same preamps for
which Sound Devices, LLC is world-
famous. These active-balanced preamps
are sonically pure with extremely low self-
noise, high headroom, and low distortion.
They also include excellent input limiters,
which keep the input from overloading,
even with unexpected loud noises or
shouting right into the microphones. And
they include full-spec 48 V phantom for
high-quality condenser mics and low-cut
lters to cut wind noise and room rumble.
The front panel has the following features:

Feature Description
Transport Controls Five large, backlit buttons for transport controls: Stop, Rewind, Play,
Fast Forward, and Record.
Gain Controls (1-2) Two dedicated gain controls for XLR inputs 1 and 2.
Gain range for both XLR inputs is -∞ to +72 dB.
1-2 Link LED Indicates when XLR inputs 1 and 2 are a linked stereo pair.
Metering LEDs Track metering LEDs
Active Limiter LEDs Illuminates when limiting occurs.
Limiter Enabled LED Illuminates when limiter is enabled.
Line LEDs Illuminates when XLR inputs are set to line level; Off when set to
Mic.
High-Pass Filter LEDs Illuminates when the low-cut lter is enabled for the XLR input(s)
Phantom LEDs Illuminates when phantom power (48 V) is active for the input(s).
Top Panel
The top panel provides the multi-pin connector and mounting screw used to
connect the accessory to the bottom panel of PIX-E monitors.

iThe PIX-LR attaches to the bottom panel of PIX-E monitors. Sound Devices, LLC
recommends, as a best practice, the monitor’s power be turned off and unplugged before
afxing the accessory. Further instructions for attaching the PIX-LR to your monitor is
provided in the PIX-LR Quick Start Guide, which is shipped with the accessory. It is also
available as a free PDF download from the Video Devices website.

PIX-LR AUDIO INTERFACE
Back Panel
The back panel has the following connectors:
Mic/Line In
(1 & 2)
Line Out
(1 & 2)
Feature Description
Mic/Line Two XLR connectors for active-balanced, analog microphone- or
line-level inputs (1 and 2). [Pin-1 ground; pin-2 (+); pin-3 (-).]
Line Out Two standard, 3-pin XLR connectors for balanced, line-level analog
outputs. [Pin-1 ground; pin-2 hot (+); pin-3 cold (-).]
In addition to their use as normal balanced outputs, the XLR outputs
may also be connected as unbalanced. When doing so, connect pin 1
to ground, pin 2 to signal, and leave pin 3 unconnected.
Assigning Audio Input Sources to XLR
When the PIX-LR is attached, both XLR 1 and XLR 2 options become viable
audio sources for the PIX-E monitor.
To set the audio input source to the PIX-LR inputs:
1. Press the Audio soft key button to access the Audio screen.
1. Use the Control knob to select the track to adjust.
2. Turn and press the Control knob to select the track’s Source eld.
3. Set the input source to XLR 1 or XLR 2.
iThe Audio screen is slightly different when the PIX-LR is attached. For more
information, see Audio Screen Differences with PIX-LR.

Modifying Audio Settings
When the PIX-LR is attached to a PIX-E monitor, additional settings become
available via the monitor’s Audio submenu.
To modify the Audio submenu’s PIX-LR settings:
1. Press the MENU button to view the Main menu.
2. Select Audio and adjust settings as needed.
The settings associated with the PIX-LR are:
setting Description
XLR 1 Input Sets input type for XLR 1. Default is Line. Options include: Line,
Mic, Line 48V Phantom, Mic 48V Phantom
XLR 2 Input Sets input type for XLR 2. Default is Line. Options include: Line,
Mic, Line 48V Phantom, Mic 48V Phantom
The default setting for both inputs is Mic.
i48 V phantom is needed to power many professional condenser
microphones. If using professional dynamic microphones, 48 V
phantom is not needed and can be turned off.
XLR 1 Input Low Cut Sets low cut frequency for analog XLR input 1. Options include:
Off, 40 Hz, 80 Hz, 120 Hz, 160 Hz, 200 Hz, or 240 Hz
XLR 2 Input Low Cut Sets low cut frequency for analog XLR input 2. Options include:
Off, 40 Hz, 80 Hz, 120 Hz, 160 Hz, 200 Hz, or 240 Hz
Input Low Cut settings for both XLR inputs are off by default.
iThe low cut lter removes low-frequency bass sound, such as
wind noise or room rumble, to make microphones sound better.
If the input sounds too “rumbly,” turn on the low-cut lter to the
lowest number needed to make the input sound better.
XLR Input Linking Selects whether the input levels are controlled independently
(unlinked) or as a stereo pair (linked). Options include: Off, 1-2
Linked without Pan, and 1-2 Linked with Pan. Linking is off by
default.
For more information, see Adjusting Gain with the PIX-LR.
iLimiters are linked and will act together.
XLR Input Limiter Turns XLR input limiter on or off. Limiter is on by default.
A limiter quickly and automatically turns an input down mo-
mentarily, just enough to keep the input from overloading and
sounding very distorted. This automatic gain-reduction happens
only during the overload, and otherwise does not affect the in-
coming signal.
iSound Devices, LLC recommends always keeping the limiter
turned on.
