PIX-LR Audio Interface
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 worldfamous. These active-balanced preamps
are sonically pure with extremely low selfnoise, 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
filters to cut wind noise and room rumble.

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.
LL
48 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.
LL
XLR Input Linking
The low cut filter 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 filter to the
lowest number needed to make the input sound better.
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.
LL
XLR Input Limiter
Limiters are linked and will act together.
Turns XLR input limiter on or off. Limiter is on by default.
A limiter quickly and automatically turns an input down momentarily, 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 incoming signal.
LL
10
Sound Devices, LLC recommends always keeping the limiter
turned on.

Setting
XLR Output Source
Description
Sets the XLR output source. Options include:
• XLR Input 1,2
• Tracks 1,2
• Tracks 3,4
• Tracks 5,6
• Tracks 7,8
• All tracks summed - mono
• All tracks summed - stereo
When set to All tracks summed - mono, all tracks (12345678) go
to both 1 and 2.
When set to All tracks summed - stereo, odd tracks (1357) go to
1 and even tracks (2468) go to 2. By default, the source is set to
All tracks summed - stereo.
The source chosen for this setting is displayed on the monitor’s
Audio screen. For instance, when set to the default of All tracks
summed - stereo, the Audio screen displays XLR Out: Tracks
1357, 2468 in the upper right corner.
LL
When XLR Input 1,2 is chosen as the output source, then XLR 1,2
is used while recording. During playback, however, the source
used is Tracks 1,2. Once playback is stopped, the output source
reverts back XLR Input 1, 2.
XLR Output Attenuation
Adjusts output attenuation in 1db increments: 0 to -20dB, Off
XLR output attenuation is set to 0 dB by default.
PIX-LR LED Meters
Sets the PIX-LR LEDs to meter specified pairs. Options include:
• Tracks 1 & 2
• Tracks 3 & 4
• Tracks 5 & 6
• Tracks 7 & 8
• XLR 1 & 2
By default, LED metering is set to XLR 1 & 2.
LL
When XLR 1 & 2 is chosen for LED metering, then metering of
XLR inputs 1 and 2 is used while recording. During playback,
however, the LEDs show the metering of Tracks 1 and 2. Once
playback is stopped, LED metering reverts back to XLR 1 & 2.

Audio Screen Differences with PIX-LR
The PIX-E monitor’s Audio screen differs slightly whenever a PIX-LR is attached.
For instance, when the audio input source for any track is set to XLR 1 or XLR 2,
the corresponding fields in the Gain column can no longer be selected by using
the monitor’s Control knob. Additionally, after the XLR Output Source is set, the
chosen source is displayed in the upper right corner of the Audio screen.
Input gain is grayed out;
Adjust only from PIX-LR
XLR output source
Track’s Audio
Source set to
PIX-LR Inputs
Highlight
Levels shown in the Gain column of the Audio screen are normally adjusted with
the Control knob, but when a track’s audio source is set to XLR inputs, level adjustment is transferred to the PIX-LR’s rotary gain controls. Therefore, the fields
in the Gain column become disabled (grayed out) and are no longer adjustable
from the Audio screen, using the Control knob. Although disabled, the fields in
the Gain column still display present levels and any adjustments as they are
made from the PIX-LR. This is particularly useful when XLR Input Linking with
or without Pan is enabled, because the Audio screen shows the changes in gain
levels while adjusting overall levels or the balance between inputs.
Adjusting Gain with the PIX-LR
With the PIX-LR attached and a track’s audio source set to an XLR input,
manual adjustment of gain levels is transferred to the PIX-LR’s rotary gain
controls.
For instance, if the source for Track 01 is set to XLR 1 and Track 02 is set to XLR
2, then turning gain control 1 adjusts levels for Track 01 on XLR 1, while turning
gain control 2 adjusts levels for Track 02 on XLR 2.
This functionality changes, however, when Input Linking is enabled, which
may be set with or without pan. When enabled, the linkage is indicated by the
amber illumination of the 1-2 Link LED on the front panel of the PIX-LR, and the
gain controls operate differently depending on whether pan is included in the
configuration.

As shown in the previous illustration, when linking is set to 1-2 Linked without
Pan, gain control 1 adjusts the overall gain level of both XLR inputs, while gain
control 2 is disabled.
When linking is set to 1-2 Linked with Pan, gain control 1 still adjusts the overall level of both XLR inputs, but gain control 2 adjusts the balance between the
inputs, as shown in the next illustration.

• Turning gain control 2 counter-clockwise fully attenuates XLR input 2.
• Turning gain control 2 clockwise fully attenuates XLR input 1.
Equal balance of the two inputs is achieved by setting the controls to center
position.

The XLR source options provide a low-latency path to the headphone
monitor and to the XLR outputs. When monitoring track sources on
headphones or the XLR outputs, the track audio is delayed to match the
displayed video.
LL When HP Source is set to any of the XLR options, playback temporarily switches
the source for headphone monitoring to Track 1,2. After playback is stopped, the
source reverts back to the actual XLR option selected.
