Welcome to the 888

UNPRECEDENTED RECORDING POWER - ON A CART OR OVER THE SHOULDER.

Meet the 888 - the portable mixer-recorder that’s compact and light enough to use in a bag, yet has the high channel count and power required
for mobile cart productions. The 888 is the smallest portable mixer-recorder on the market that offers Dante for sending and receiving audio over
Ethernet. With 8 ultra low-noise, 8-Series microphone preampliers, 16 channels, 20 tracks, multiple powering methods, and support for multiple
USB control surfaces, the 888 can be easily tailored to your workow. An updated processing architecture and multiple FPGAs enables the 888 to
be fully routable: any physical input may be sent to any track, bus, or output.

Many features have carried over from the premium Sound Devices’ Scorpio, such as the new 8-Series preamplier design, 2 SD card slots, internal
256 GB SSD, and dual L-Mount battery charging and powering. Alternatively, power your 888 using a smart battery, NP-1 battery, or an in-line power
supply via its TA4 DC input. The ultra-accurate, fully-featured timecode generator contains its own battery to hold timecode for up to four hours after
power off.

Dedicated coms and slate allows for professional bi-directional communication with other crew members. Send customized mixes to the camera
or crew with multiple mix buses. With the ability to record to three media simultaneously, you can turn over an SD card to production, AAC les for
transcription, and keep a backup on the internal 256 GB SSD.

A built-in three band EQ may be set to either pre- or post-fade for each channel to tackle any problems directly on-set. Enable Dugan Automixing or
MixAssist to automatically attenuate unused microphones in multi-microphone applications. Up to 16 channels can be automixed at a time.

Get the perfect t on your cart with one of several supported USB control surfaces for remote fader and transport control. Download the companion
Android app, SD-Remote, to access to transport controls, metering, and sound reports on a large touch screen.

We are honored to be part of your kit.

Sincerely,
Sound Devices

DUGAN AUTOMIXER MODE

Dugan gain display bars are overlaid on top of the channel signal
meters. The top 15 dB of the meter scale is shared between Dugan
gain display bars and audio signal metering. Dugan gain display bars
range from 0 dB (at the top, aligned with 0 dBFS, no attenuation) to

-15 dB (max attenuation). The -15 dB value is indicated by a purple
horizontal graticule mark to the left of a channel’s signal meter when
that channel is enabled for Dugan in Menu>Automixer.

There are two independent Dugan processing groups, Bus L and Bus
R. Channels 1-16 can be routed to Bus L, Bus R, both equally (Center),
or both unequally (L or R pan increments) by using a channel’s pan
control.

To show which Dugan group the channel is in, the Dugan gain display
bar is left-aligned for fully L, right-aligned for fully R and center-aligned
for any other pan value. When a channel is routed to both Dugan
groups (Bus L and R), the center-aligned gain display bar shows the
least attenuated value.

The Channel Screen shows the Dugan gain display bar overlaid within
the horizontal channel meter. The Dugan gain display scale and indi­cation is the same as in the main meter screen.

The ring LEDs for ch 1-8 show Dugan gain for ch 1-8. The ring LEDs
begin to glow purple at 15 dB attenuation and increase in intensity at
0 dB attenuation.

The 888 is capable of connecting to a Dante network, simultaneously
receiving and sending up to 16 channels of audio at sample
rates from 44.1kHz up to 192 kHz. 888 channels 1-16 may be
sourced from Dante receive channels 1-16. Each Dante input
may be selected as a source in the Channel Setup menu. Each
Dante output may be sourced from ISOs (pre- or post-), Buses
and Outputs (post-delay). All network routing should be done
through Audinate’s Dante Controller application, found at www.
audinate.com. Once the initial conguration has been performed,
the 888 will keep its Dante conguration through power cycles. It
is recommended that, in most situations, the 888 is selected as
“Preferred Master” under the “Clock Status” tab of Dante Controller.

USB-A

USB-A allows multiple devices to be used to control and monitor vari­ous functions of the 888. Should multiple devices be used simultane­ously, the use of a USB-A type hub is required.

USB-C

USB-C allows for high-speed le transfer between a computer and any
of the 888’s media.

All other functionality is suspended in USB File Transfer mode.

Glossary

¼-inch jack

Common analog audio connector used as both an audio input and
output. When a ¼-inch jack is described as TRS (tip-ring-sleeve) it
can be wired as either a balanced connection or as a two-channel
connection. ¼-inch headphone jacks are typically wired as TRS stereo
jacks.

3.5 mm jack

Common small-format audio connector. Often used for headphones
and -10 dBV signals for portable audio devices.

AES3

A standard for the exchange of digital audio signals between
professional audio devices. An AES3 signal can carry two channels of
PCM audio over balanced, 110 ohm interconnections. AES3 is most
commonly interconnected with XLR-3 cables.

AES42

A digital interface protocol for microphones and microphone inputs.
Microphones conforming to this standard directly output digital audio
through an XLR or XLD male connector, rather than producing an
analog output. AES42 microphones require powering.

Attenuation

A reduction in the level of an audio signal. Attenuation can be
applied to both analog and digital signals. A fader is used primarily
to attenuate signals, though a small amount of positive gain is often
available on a fader.

Bus

An audio path that is the destination of one or multiple (mixed)
channels. A bus is typically routed to an output, a record track, or
both.

Camera return

An audio input on a mixer designed to receive the output, typically the
headphone output, of a camera. Camera return inputs allow the user
to monitor the level and quality of the signal received at the camera.
On the 888, the camera returns can be used as a source for any
channel.

Channel

A “slot” of a mixer that is controllable and routable. A given input
feeds the channel and the channel’s settings process and route the
audio as required. It can also be thought of as the path its selected
input signal takes on its way to its record track, a bus, or an output.

Channel grouping

With the 888, any of the 16 channels can be grouped together so
that their faders, record arming state mute states can be controlled
together. Channel grouping can be used as an alternative to sending
channels to a bus.

Circled take

An identifying character, the @ symbol, which is placed in the le
name to highlight a take. Circled takes can either be used to identify
good takes or to identify tracks or takes that will be ignored.

Bext chunk

Broadcast WAV extension data added to the audio data in a WAV le.
The bext chunk includes timecode and user bit data. For systems that
do not recognize the bext chunk this additional information is ignored.

Bit depth

When converting between analog and PCM digital audio the
amplitude of an analog signal is measured in nite steps, measured
in bits. Higher bit rates result in greater resolution of amplitudes,
resulting in higher dynamic range. 24-bit audio, with a theoretical
maximum dynamic range of 144 dB, is the standard bit depth used
throughout the audio chain for production.

Broadcast WAV, BWAV

Broadcast WAV les are WAV les with additional, non-audio data,
such as bEXT chunk data. Broadcast WAV les offer timecode
support.

Com return

A dedicated audio input designed to receive signals from a PL, or
private line communications circuit. The com return on the 888 can
routed to an output or a bus.

Com send

A dedicated output designed to send signal to a PL (private line,
talkback) communications circuit. The com send is toggled by a front
panel switch.

Dante

A combination of software, hardware, and network protocols that
deliver uncompressed, multi-channel, low-latency digital audio over a
standard Ethernet network using Layer 3 IP packets.

dBFS

A measurement of the signal level of a digital signal in dB increments,
dB relative to full scale signal. The maximum signal in dBFS is 0
dBFS, with signals expressed with a negative sign. dBFS signal
strength is an internal measurement and does not correspond to
analog signals unless the relationship between analog signal and
digital signal is known.

Delay (channel)

Time delay that can be applied to an individual channel. Channel
delay, typically set in milliseconds, is often used to compensate for
different acoustical or electrical arrival times of signals between
channels.

888 User Guide

41

Ethernet

A family of computer networking technologies. Ethernet commonly
refers to the physical interconnection of the network typically using
twisted-pair copper connections on CAT cable with RJ-45 connectors.
Common Ethernet data speeds include 10 Mbs, 100 Mbs, and 1000
Mbs.

exFAT

A storage volume format that can be read and written from current
versions of MacOS and Windows. exFat supports volume sizes up to
128 PB (gigantic), and individual les can have a maximum size of 16
EB (even more gigantic, bigger than the maximum volume size).

Fader

A physical control on a mixing console, either a rotary or sliding
potentiometer, that controls the level of a channel to a bus. Most
faders have more attenuation than gain available and a unity gain
position where the input trim level established the level to the bus.

False take

A recorded take that was either erroneously recorded, or a take that
needs to be repeated. It can be labeled after recording. An identied
false take is moved to the trash bin and the auto-incrementing take
number is reset to the value prior to the false take.

File list

Every le recorded by a recorder is visible in the le list. It can be
viewed either on a recorder or from a computer when the recording
volume is mounted. The le list shows all the individual les recorded
by a recorder.

Frame rate

The rate at which video or motion picture images are recorded or
played back, measured in frames-per second (FPS). All audio and
video devices must be running at the same frame rate to keep audio
and video synchronized. Timecode frame rates are either an integer
or non-integer value. Integer values include 24, 25, and 30 FPS. Non­integer frame rates include 23.976 and 29.97, and 29.97 drop FPS.

Frequency

The period at which a wave oscillates, measured in hertz (Hz).
Frequencies audible to humans range from 20 Hz for very low
frequency signals to 20 kHz for very high frequency signals.

Gain

An increase (or decrease with negative gain) in the level of an audio
signal. Gain can be applied in several locations, to both analog
and digital signals. In a eld mixer the microphone preamplier
provides a substantial amount of gain at the trim to raise the low
level microphone signal to a usable signal in the mixer. Gain is also
available at the fader. Gain of digital signals or line level analog
signals is often limited. Unity gain is gain stage that neither adds or
subtracts level from a signal.

Headphone monitor

Often a separate bus with a dedicated headphone volume control,
the headphone monitor typically is normalled to the main left/right
output bus of a mixer. Headphone sources can often be selected
among soloed tracks or buses. In some products complex headphone
monitoring of MS Stereo, LR stereo, and ambisonic sources is
available.

High pass lter (audio)

Also referred to as a low-cut lter, this circuit reduces the amount of
low frequency content in an audio signal. A HPF is particularly useful
when recording speech since the human voice does not generate
appreciable energy at low frequencies. The HPF reduces non-speech
signals such as environmental noise, wind noise, and microphone
handling noise, improving the intelligibility of speech and reducing low
frequencies from overloading the input. The high pass lter is placed
in the circuit close to the microphone preamplier.
High pass lters are often frequency selectable, ranging from 20 Hz to
200 Hz. HPF also have a slope, generally from 3 dB/octave to 18 dB/
octave. Greater/steeper slopes offer more attenuation of frequencies
just below the set lter frequency.

Input

The physical connection and associated signal type from external
sources connected to a device. Inputs can include microphone inputs
on XLR connectors, Dante inputs on audio-over-Ethernet, and USB
audio inputs from a computer. Depending on the architecture of the
mixing console its inputs may be hardwired to channels or channels
can be selected from different inputs.

Input limiter

A limiter circuit reduces the peak signal levels of audio, generally to
prevent signal overload. Analog inputs have a maximum input signal
level that can be reached before overload/distortion is introduced.
Setting the input gain correctly so that input signals do not reach this
maximum level prevents most overload conditions. In the presence of
very high, unexpected signals an input limiter changes the gain of the
incoming signal and prevents it from overloading. Input limiters are
sometimes compressor-type circuits with a ratio of innity:1, meaning
that any increase to the input signal into the limiter at the limiter
threshold does not increase the output signal of the limiter.
Several parameters may be available in a limiter, including knee, ratio,
release, and threshold.

Isolated track

A recorded track of an individual microphone or sound source. “ISO”
recordings allow for post-record mixing of individual sound elements.

iXML

An extensible data schema for audio and related metadata stored
in broadcast WAV les. Manufacturer-specic data generated during
recording is stored in iXML.

Line level

An analog audio signal used to interconnect audio equipment. Line
level may be balanced or unbalanced, referenced to +4 dBu or -10
dBV, professional or consumer respectively.

Low cut lter

See high pass lter.

Microphone level

The audio signal generated by a microphone. Mic level signals are
very low level, requiring a microphone preamplier to bring them to
usable, line levels. Interconnects with microphone level signals can be
subject to noise and interference.

888 User Guide

42

Mid-side linking (inputs)

When mid-side (MS) stereo inputs are used and the inputs are set to
MS linking and MS decoder is activated for those inputs. This yields
a stereo signal with one fader controlling overall input level and the
other fader controlling the “width”, or amount of the side signal
added. With an MS matrix at the input, the signal is sent to an output
bus as left/right stereo. Mixers with MS matrices often allow for
discrete mid and side signal recording. In that case the MS decoder
can be activated at the headphone selection to monitor left/right
stereo.

Mix track

A recorded track that is a sum of multiple tracks. In production sound
the mix track is often a single summed track of all production dialog
elements. Mix tracks can also be sub-mixes of like microphones, such
as a sub mix of just lavalier microphones or just boom microphones.

Monophonic WAV

A WAV le that is comprised of a single track of audio. When recording
multi-track audio with monophonic WAV les each track is recorded
to its own WAV le, with a le name indicating the track number. All
associated monophonic les that are part of a multi-track recording
will be identical lengths.

Mute

A mute control is a convenient on/off switch for a channel and an
easy way to remove a channel from appearing in downstream buses.
Mute an input or channel does not change levels or settings; when
channels are muted and unmuted, their settings remain.

Notes (metadata)

A metadata eld that is saved along with audio data in a recorded
sound le, useful for sound report generation. Some workstation
software recognizes the notes eld and presents it when viewing the
sound le.

Output

The physical connection and associated signal type sent from a
device. Outputs can be source from inputs, buses, record tracks, and
other auxiliary signals.

Output auto-mute

When set, an output signal is muted when recording is stopped,
restricting program audio from being sent to listeners “between
takes”.

Output delay

A digital delay applied at the output. Signal delay is often set at an
output to compensate for the delay introduced by digital imaging
systems so that picture and sound remain in correct “lip sync”. Output
delay is set in either frames or milliseconds.

Pan

When a channel is routed to a stereo-linked bus the level it appears at
each bus is adjusted by a pan control. A channel with its pan control
“straight up the center”, or “centered” sends signal at the same level
to each bus. A channel that is panned left or right sends the signal to
the left or right bus, respectively.

PFL, pre-fade listen

When an input or channel is selected for monitoring/solo with a PFL,
the channel is routed to the headphone output before the channel
fader so that the fader position has no effect on the headphone level.
Trim/gain changes to the input will change the headphone output.

888 User Guide

Phantom power

Condenser (capacitor) microphones require power for operation. They
use power to charge the diaphragm backplate (for true condensers)
and power the impedance convert located adjacent to the
microphone capsule. Phantom power is the method for microphone
inputs to supply DC power to the microphone through the same
connection used for the audio signals from the microphone.

Phantom power provides a positive voltage, typically between 11-52
VDC, with 48 V being the most common, on both pin-2 and pin-3 with
pin-1 used as ground. The DC voltage appears as a common-mode
signal on the balanced connection and is rejected by the connection’s
differential amplier. Phantom power has no effect on dynamic
microphones.

Phase

The relationship one audio signal has in time with respect to another
audio signal, dened in degrees of phase. When audio signals are
generated at identical times, they are “in phase” with each other.
When one audio signal is time-delayed with respect to another the
signals are “out of phase”. Differing phase relationships can be
introduced several ways, including when microphones are placed at
varying distances from a sound source, or electrical/digital delay is
introduced to one signal with respect to another.

Phrase

A pre-set text string which can be used to quickly ll out the notes
eld.

Pre-fader routing

The signal from a channel is routed to a bus before the fader in the
signal path. The input trim, if available, controls the channel level sent
to the bus. Isolated tracks are typically recorded pre-fader so that any
level changes made to the faders don’t affect the recorded signal.

Pre-roll

A continuous buffer that is always writing to memory offering a
recording that begins prior to when the record button is activated.
Pre-roll is set in seconds, and the recording begins the set number
of seconds prior to the button being pressed. This is helpful in
applications where an operator missed a cue to begin recording.

Polarity (audio)

The direction of the current ow of an audio signal is dened as
polarity. The polarity of a signal can reversed when a balanced audio
signal connection has its pin-2 and pin-3 connections reversed.
Single-ended signals can have their polarity reversed when going
through an “inverting” gain stage. It is best practice to have all
incoming and outgoing signals with the same polarity relationship.

Polyphonic WAV

An individual WAV le that contains multiple audio tracks. When
recording multi-track audio with polyphonic WAV les all recorded
tracks are contained within a single WAV le.

Post-fader routing (after fade routing, AFL)

The signal from a channel is routed to a bus after the fader in the
signal path. The fader controls the level of the channel at the bus.
Channels sent to a master bus, such as the left/right bus, are
typically sent post-fader.

43

Post-roll

An extra period of time that is appended to the end of a recording
when stop is pressed. If record is pressed during this period of
time, recording will resume within the same le with no audio lost.
This is particularly useful should a Director call ‘cut’ prematurely or
accidentally.

Project

An option available for le organization on Sound Devices recorders.
Projects are the highest level of le folder organization. The project
folder can contain sub-folders of scene les or recorded les directly.

Record bell

A tone generated in headphones to alert the listener that recording
has started. The bell is also produced when recording has ended with
the stop button, when the recording volume is full, or when power is in
a critical state.

Sampling rate

When converting between analog and PCM digital audio the analog
signal is measured (sampled) in unique steps at a data rate specied
in kHz. Higher sampling rates allow for representing higher frequency
analog audio. 48 kHz is the standard sampling rate for production,
worldwide. Higher sampling rates including 96 kHz and 192 kHz are
used for high-precision applications where the representation of audio
above 20 kHz is required. A general rule is that the maximum analog
audio frequency is ½ the sampling rate.

Scene

On Sound Devices recorders the scene becomes part of the le
name for a take. Scene names can be pre-loaded to quickly change
between scenes.

Slate microphone

A microphone, built-in or external microphone, on an audio mixer used
to notate takes or communicate with sound team members by the
mixer’s user speaking into the microphone. Slate microphones are
often routable to buses or tracks.

Stereo linking (inputs)

When active for stereo sources such as stereo microphones, linked
inputs are hard panned to the left and right bus. Controls including
gain (trim), fader, high pass lter, delay, limiter, mute, and routing are
controlled together.

Sticky Notes

Notes that persist to subsequent takes.

Solo

A control on a mixer to route a channel to headphones while muting
all others. Solo and PFL are related controls and in many consoles are
the same. Solo circuits can be exclusive—only one channel is sent to
headphones at a time—or non-exclusive—any number of channels can
be sent to the solo circuit and appear in headphones.

TA-type connector (TA3, TA4, TA5, TA6)

Miniature XLR-type, locking connectors. TA3 connectors are used
by Sound Devices for various inputs, outputs, and as balanced and
unbalanced connections. TA4 connectors are used by Sound Devices
for DC power connections to the 888 mixer-recorder. TA4 is also used
for audio connections from lavalier microphones to some wireless
transmitters. Ta5 connectors are used for Mic/Line inputs and the
headset on the 888. TA6 connectors are presently not used by
Sound Devices though they are used for audio connections by other
manufacturers.

Take

A recorded take is an individual recorded le (or les when recording
monophonic WAV les) generated by a recorder. Take numbers are
auto-incrementing. Take numbers are added to the end of the le
name.

Take list

Separate from a le list, a take list consolidates related les such
as a group of monophonic WAV les generated by a single take and
presents them as a single take.

Test tone

See tone oscillator.

Timecode

A numerical clock value expressed in hours:minutes:seconds:frames,
i.e. 04:59:39:05, used to synchronize cameras, video decks,
and audio recorders. Timecode requires clocks on devices to be
synchronized, either through a wired or wireless connection between
devices, or through a process called “jam sync” where each device,
which requires a high-precision clock, runs independently after their
clocks are synchronized.

Timecode mode

Sound Devices recorders offer multiple timecode modes. Different
modes correspond to different timecode workows. Common modes
available in Sound Devices recorders include:
Record run - timecode advances only when recording is engaged.
Free run - timecode run continuously, typically with the start of
production being at 0 hour.
24 hour - similar to free run except the start time corresponds to time­of-day.
Ext TC - the recorder applies the value of an external timecode source.

Tone oscillator

A sound generator producing a sine wave tone at a given frequency at
a given output level. With its known output level tone oscillators are
helpful to set gain structure between audio equipment.

Track

A single recorded audio signal. Common recorded tracks are the main
left/right master audio bus and isolated (ISO) channel recordings. ISO
tracks are typically identied by the channel of the same number, e.g.
channel 1 is sent to track 1, channel 2 is sent to track 2, etc.

Track arm

Tracks that are active and ready for recording are said to be “armed”.
When recording begins all armed tracks begin recording. Depending
on the production is may be advantageous to arm and disarm tracks,
especially to disarm unused tracks.

Track name

Individual tracks of a multi-track recording can be named to indicate
microphone type or character name.

Trim

Also dened in mixers as “gain”, the trim adjustment is the rst
stage of gain of a microphone or line level input. Typical microphone
trim values range from 10 dB to 50 dB, depending on microphone
sensitivity and volume of the sound source.

44

User bits

Static, numeric data that is available as part of a timecode signal.
User bits are often used to indicate the date of a le. User bits are
four sets of two-digit hexadecimal numbers from 00 to ff.

WAV File

A universal, well-supported le type for sound le recordings. WAV les
can contain one or more (up to 65,535) tracks of PCM audio data at
any sampling rate and bit depth. A standard WAV le is limited to a
maximum le size of 4 GB. Sound Devices uses the WAV extension for
recorded les, including for les with Broadcast WAV metadata and
WAV RF64 les.

WAV RF64

An extension of the WAV le type that supports le sizes larger than 4
GB. When recording high track count, high sampling rate polyphonic
WAV les, the 4 GB size limitation of WAV can be reached quickly.
RF64 les larger than 4 GB require recording to a volume type than
can support le sizes larger than 4 GB.

Word clock

A reference signal used to synchronize the sampling rate of multiple
digital devices.

XLR female

Industry-standard 3-pin locking audio connector for microphone and
line-level sources. Predominantly used as an input. Also shown as
XLR-F

XLR male

Industry-standard 3-pin locking audio connector for microphone and
line-level sources. Predominantly used as an output. Also shown as
XLR-M
