Quick Reference: 828mk3 Front Panel
The phone jack labeled (MAIN) is a standard quarter-inch stereo headphone jack.Its output is hard-wired to mirror the XLR main outs on the rear panel.From the factory,the MASTER VOL knob above it controls the main outs and this jack,but MASTER VOL can be programmed to control any combination of outputs.See “The Monitor Group”on page 88 for details.Push the knob once to view the current volume setting in the LCD display;push it again to mute the monitor group;push a third time to return to the previous volume.Note:if the Monitor group is programmed to not include the main outs,the MASTER VOL knob will no longer control the volume of this phone jack,either.
These round LEDs indicate signal presence on the 8 rear- panel TRS analog and SPDIF outputs.Their threshold is around -42 dB.They do not indicate clipping in any way; use your host audio software level meters to calibrate output levels.
The multi-purpose backlit LCD shows system settings or CueMix FX settings,depending on which knobs you turn.The labels above and below the LCD refer to the four digital rotary encoders to the left of the LCD.These knobs let you access and program all settings in the 828mk3.
These lights indicate the global sample rate at which the 828mk3 is operating.Use the MOTU Audio Console software to set the sample rate or to choose an external clock source,from which the sample rate will be derived.When no clock signal is currently present,one of these LEDs flashes rapidly.
FireWire and USB are“plug- and-play”protocols.That means that you can turn off the828mk3 and turn it back on without restarting your computer.
These two trim knobs provide approximately 53 dB of gain for the lo-Z XLR mic input and the hi-Z TRS guitar/instrument input.Both inputs have preamps,so you can plug just about anything into them:a microphone,a guitar,a synth — but don’t plug in a +4 signal here (due to the preamps):use a rear-panelTRS input instead.Use the trim knob and the“MIC”input level meters over in the metering section to calibrate the input signal level.The meters cover both theTRS and XLR input.These mic inputs are also equipped with the 828mk3’s V-Limit™ hardware limiter,which provides an additional +12 dB of headroom above zero with no clipping or digital distor- tion.See “Mic/guitar inputs meters with V-Limit™ compressor”on page 42 for details.
These XLR/TRS combo jacks accept either a mic cable or a quarter-inch guitar cable.Both the low-impedance XLR jack and the high-impedanceTRS jack are equipped with a preamp (so don’t connect a +4 line level XLR cable!).For the Mic (XLR) input,push the TRIM encoder to toggle a 20 dB pad;push and hold to toggle 48V phantom power.The Precision DigitalTrim™ knob provides 53 dB of gain.Use the rear panel sends to route these inputs to your favorite outboard gear.Use any rear-panel input as a return.
From the factory, the PHONES jack is a discrete output (at 44.1/48 kHz), but it can mirror any other output pair (digital or analog).For example,at 88.2/96 kHz,it defaults to mirroring the main outs. As the primary phone jack, it has its own dedicated volume knob.
Push the CHANNEL knob repeat- edly to cycle among the four main sections of the mixer:mix busses,inputs,outputs and the reverb module.Push the PARAM knob to enter the SETUP menu, which provides global 828mk3 settings,such as the global sample rate,etc.
This section controls the 828mk3’s built-in CueMix FX mixer and effects.There are eight stereo mix busses:each bus mixes all inputs (or any subset you wish) to a stereo output of your choice. You can apply EQ,compression,and reverb to inputs,outputs and mix busses.The four knobs to the left of the LCD correspond directly to the four labeled sections of the LCD.Use the CHANNEL knob to choose the input,output or mix you wish to edit.Push it to switch among inputs,outputs and busses,then turn it to choose the desired channel or bus.Use the PAGE,PARAM andVALUE knobs to access the mix settings for the chosen channel.
This bank of input meters is for the 8 analog TRS input jacks on the rear panel.
This section provides two ten-segment meters for the two front-panel mic/guitar inputs.The meters show input levels from -42 to -1 in the first column of LEDs,plus an additional range in a second column from zero to +12 dB (including clip).Both inputs are equipped with V-Limit™,a hardware limiter.With the limiter turned off, signals that hit zero or above will clip (a hard digital clip).However,with V-Limit turned on,signals can go as high as +12 dB above zero with no digital clipping.If the signal then goes above +12 dB,it will clip,even with V-Limit engaged.
When the 828mk3 is resolving to SMPTE time code,the LOCK/ TACH LED glows when lockup has been achieved.The ADAT and MIDI LEDs blink when there is optical audio or MIDI activity, respectively.
5-segment metering for the main outs.Use the MASTER VOL knob to control output level.
4-segment meteringfor SPDIF input.

Quick Reference: 828mk3 Rear Panel
Connect the 828mk3 to the computer here via either FireWire or USB2,using either the standard 1394 FireWire B or USB cable provided with your 828mk3. If you use FireWire,you can also use the second FireWire port to daisy-chain up to four MOTU FireWire audio interfaces to a single FireWire bus,or connect other FireWire devices.Keep in mind that the 828mk3 uses more FireWire bus bandwidth when one or both optical banks are enabled,or when it operates at higher sample rates.These operating configurations will limit the number of devices you can daisy chain on a single FireWire bus.For details,see “Connect- ing multiple MOTU FireWire interfaces” on page 31.
These jacks provide stereo, 24-bit S/PDIF digital input and output at all supported sample rates (up to 96 kHz).
These two XLR jacks serve as the 828mk3’s main outputs.You can connect them to a set of powered studio monitors and then control the volume from the front panel MASTERVOL knob. To hear audio playback from your host audio software on these main outs, assign the audio tracks (and master fader) to these main outs.You can also use CueMix FX to monitor live 828mk3 inputs here as well.
Equipped with 24-bit 192 kHz converters, these 8 analog inputs are gold-plated, balancedTRS (tip/ring/sleeve) quarter-inch connectors that can also accept an unbal- anced plug.They do not have microphone preamps,so they are best used for synthe- sizers,drum machines,effects processors, andother instruments withline level signals (either -10 dB or +4 dB).These inputs are also equipped with the 828mk3’s Precision Digital Trim™ feature:digitally controlled analog trims that let you adjust input level in 1 dB increments from either front panel LCD or the included CueMix FX software.The trim can be adjusted over a range of -96 to +22 dB.
These two quarter-inch balanced TRS send outputs supply the pre amplified input signal from the mic/guitar/ instrument inputs on the front panel.Use them to insert your favorite compressor, EQ, reverb or other outboard effect.Use anyTRS input as a return.
The 828mk3’s eight analog outputs are gold-plated,balanced +4dB TRS (tip/ ring/sleeve) quarter-inch connectors that can also accept an unbalanced plug. They are equipped with 24-bit 192 kHz converters.
These optical digital I/O connectors can be connected either to an ADAT-compatible“lightpipe”device (such as a digital mixer) or to a S/PDIF optical (“TOSLink”) compatible device,such as an effects processor or DAT machine.Be sure to set the format in the MOTU Audio Console software (or using the front panel LCD).(see “Optical input/output”on page 39) for details.) ADAT optical supplies eight channels of 24-bit digital I/O per bank (4 channels per bank at 96kHz).TOSLink is stereo at sample rates up to 96 kHz. One special note:you can choose independent formats for each bank,A and B,as well as IN and OUT within each bank.For example,you could choose ADAT for the optical A IN (for,say,eight channels of input from your digital mixer) and stereoTOSLink for the optical A OUT (for, say,your DAT machine).
Connect a standard foot switch here for hands-free punch-in and punch-out during recording.For details about how to set this up, see “Enable Pedal”on page 39.
These are standard BNC word clock jacks.Use them for a variety of applications,such as for digital transfers with devices that cannot slave to the clock supplied by their digital I/O connection with the 828mk3. When the 828mk3 is operating at a high sample rate (88.2 or 96 kHz),you can force the word clock output rate (via software or the front panel) to 44.1 or 48 kHz.
Connect a MIDI device here using standard MIDI cables. Connectthe 828mk3’s MIDI OUT port to the MIDI IN port on the other device.Conversely, connect the 828mk3’s MIDI IN port to theMIDI OUT porton the other device.You can connect different devices to each port, such as a controller device to the IN port and a sound module to the OUT port.You can also daisy-chain MIDI devices,but be sure to manage their MIDI channels (so that they don’t receive or transmit on the same channel).
These are quarter-inch analog SMPTE input and output jacks.Use them to resolve the 828mk3 directly to time code and transmit time code to other devices.
The 828mk3 is equipped with an auto-switching international power supply.

Device Setup in Cubase
Choose the output pair you would like the
main outs to mirror,or choose Main Outs to
operate them as their own independent pair
(at sample rates up to 96 kHz).
This menu lets you choose what you will
hear from the PHONES jack.To mirror the
main outs,choose Main Out 1-2.Or you can
mirror any other output pair.To hear the
phones as their own independent output,
choose Phones 1-2 (at 44.1 or 48 kHz.At
higher sample rates,the phones must
mirror any other available output pair.)
Uncheck this option if the Windows audio
software you are using with the 828mk3
does not support Windows WaveRT drivers
and instead only supports legacy WDM
drivers.
Determines the clock source for your
828mk3.If you’re just using the analog
ins and outs,set this to‘Internal’.The
other settings are for digital transfers
via S/PDIF or optical ports,or for slaving
the 828mk3 to word clock.
Each optical bank can be configured
independently:ADAT or TOSLink.Disable
them when not in use to conserve DSP
and bus bandwidth.
Choose the global sample rate for the
system here.
If you are running an 828mk3 interface at a
high sample rate (96,88.2,176.4 or 192
kHz),this option appears in the interface
tab.It lets you choose a word clock output
rate that either matches the global sample
rate (e.g.96kHz) or reduces it to the corre-
sponding 1x rate (e.g.48kHz instead of 192
kHz).
Click the tabs to access general MOTU inter
-
face settings or settings specific to the
828mk3 (or other connected interface.)
Choosing a smaller setting here reduces
the delay you may hear when listening to
live input that you are running through
effects plug-ins in your software.But
lower settings also increase the strain on
your computer.For details,see “Samples
Per Buffer”on page 38.
Click the 828mk3 tab to access these
settings.
If you have a foot switch connected to the
828mk3,these settings let you map the
foot switch to any computer keyboard key
for both the up and down position.For
details about how to set this up, see
“Enable Pedal”on page 39.
This option should always be left on
(checked).There are only a few rare cases
in which you would want to turn it off.For
details,refer to the MOTU tech support
database at www.motu.com.
How to access these settings
The 828mk3 driver provides a stereo return
back to the computer.This return feeds the
signal on any 828mk3 output pair directly
back to the computer,where you can record,
process,monitor or otherwise use it.This is a
great way to“bounce”full mixes,complete
with live audio routed through the 828mk3
only, back into the computer.
There are several ways to access these settings:
■From theWindows Start menu,choose
Programs>MOTU>MOTU Audio Console.
■From within Cubase,go to the Device Setup
window, click the MOTU Audio ASIO list item and
and click the Control Panel button.
■From within other applications,refer to their
documentation.

THE 828MK3 REAR PANEL
The 828mk3 rear panel has the following
connectors:
■
Eight gold-plated, balanced quarter-inch (TRS)
analog outputs (with 24-bit 192 kHz converters)
■ Eight gold-plated, balanced quarter-inch (TRS)
analog inputs (with 24-bit 192 kHz converters)
■
Two XLR“main” analog outputs with 24-bit
192 kHz converters
■
Two gold-plated, balanced quarter-inch (TRS)
analog sends (for the front-panel mic/guitar
inputs)
■ Gold-plated balanced TRS quarter-inch analog
in/out dedicated for SMPTE time code
■ Two sets of optical connectors (in and out),
individually switchable among ADAT optical
“lightpipe”, 96 kHz S/MUX optical or S/PDIF
“TOSLink”
■ RCA S/PDIF in/out
■ MIDI IN and MIDI OUT
■ Word clock in/out
■ Foot pedal jack
■ Two 1394 FireWire B connectors
■ One high-speed USB2 connector
28 inputs and 30 outputs
All 828mk3 inputs and outputs can be used simul-
taneously, for a total of 28 inputs and 30 outputs
when operating at 44.1 or 48 kHz:
* The phone jack below the MASTER VOL knob is
hard-wired to (mirrors) the XLR main outs. The
PHONES output can operate as an independent
output pair, or it can mirror any other 828mk3
output pair, such as the main outs.
† The 828mk3 optical connectors support several
standard optical I/O formats, which provide
varying channel counts. See “Optical” on page 11
for details about optical bank operation.
With the exception of the phone jack on the front
panel labeled“(MAIN)”, all inputs and outputs are
discrete. For example, using a mic input does not
“steal” an input from the TRS analog I/O bank.
Analog
All analog inputs are equipped with 24-bit 192 kHz
A/D converters.All analog outputs have 24-bit
192 kHz D/A converters.All audio is transferred to
and from the computer in a 24-bit data stream.
All quarter-inch analog inputs can accept either a
balanced or unbalanced plug.

ABOUT THE 828MK3
11
The quarter-inch outputs are referenced to a +4
dBu line level output signal. The inputs have
+22 dB of input gain and -96 dB of cut, allowing
them to accommodate both -10 dBu and +4 dBu
level signals.
Precision Digital Trim™
All of the 828mk3’s analog inputs are equipped
with digitally controlled analog trims,adjustable in
1 dB increments.The mic/guitar input trims can be
adjusted using front-panel digital rotary encoders
that provide feedback in the front panel LCD with
up to 53 dB of boost.All analog inputs, including
eight rear-panel TRS analog inputs, can be
trimmed using the front panel LCD or using the
828mk3’s included CueMix FX control software for
Mac and Windows. This gives you finely-tuned
control of trim settings for synths, effects modules,
and a wide variety of analog inputs for optimum
levels. Different trim configurations can then be
saved as preset configurations for instant recall.
Mic/guitar sends
Before A/D conversion, the pre-amplified signal
from each front-panel mic/guitar input is routed to
one of the two rear-panel quarter-inch analog
sends, so that you can insert a favorite outboard
EQ, compressor, amp or effects processor to the
mic/guitar input signal before it is converted to
digital form. The resulting output from the
outboard gear can be fed back into the 828mk3 via
one of the eight TRS analog inputs on the rear
panel,for routing to the computer and/or inclusion
in the 828mk3’s built-in monitor mixes.
Main Outs
The main outs are equipped with 24-bit 192 kHz
D/A converters and serve as independent outputs
for the computer or for the 828mk3’s on-board
CueMix FX mixes.
Optical
The two optical banks provide 16 channels of
ADAT optical at 44.1 or 48 kHz, 8 channels of S/
MUX optical I/O at 96 kHz or two banks of stereo
TOSLink at rates up to 96 kHz. The banks operate
independently, including input and output,
allowing you to mix and match any optical formats.
For example, you could receive 4 channels of
96 kHz S/MUX input on Bank A while at the same
time sending 96 kHz stereo optical S/PDIF
(“TOSLink”) from the Bank A output.
S/PDIF
The 828mk3 rear panel provides S/PDIF input and
output in two different formats: RCA “coax” and
optical“TOSLink”.The RCA jacks are dedicated to
the S/PDIF format.The TOSLink jacks can be used
either for either TOSLink or ADAT optical, as
discussed earlier.
MIDI I/O
The 828mk3’s standard MIDI IN and MIDI OUT
jacks supply 16 channels of MIDI I/O to and from
the computer via the 828mk3’s FireWire
connection.
On-board SMPTE synchronization
The 828mk3 can resolve directly to SMPTE time
code via the quarter-inch SMPTE input, without a
separate synchronizer.A SMPTE out jack is also
provided for time code generation. The 828mk3
provides a DSP-driven phase-lock engine with
sophisticated filtering that provides fast lockup
times and sub-frame accuracy.
The included MOTU SMPTE Console™ software
includes a complete set of tools for generating and
regenerating SMPTE time code,providing a way to
slave other devices to the computer. Like
CueMix FX, the synchronization features are
cross-platform and compatible with all audio
sequencer software that supports the ASIO2
sample-accurate sync protocol.
!828mk3 Hyb Manual/Win Page 11 Monday, March 28, 2011 6:11 PM

ABOUT THE 828MK3
12
Word clock
The 828mk3 provides standard word clock that can
slave to any supported sample rate. In addition,
word clock can resolve to and generate“high” and
“low” sample rates. For example, if the 828mk3
global sample rate is set to 96 kHz, the word clock
input can resolve to a“low” rate of 48 kHz.
Similarly,when the 828mk3 is operating at 96 kHz,
MOTU Audio Console lets you choose a word
clock output rate of 48 kHz.
Punch in/out
The quarter-inch Punch in/out jack accepts a
standard foot switch. When you push the foot
switch, the 828mk3 triggers a programmable
keystroke on the computer keyboard.For example,
with MOTU’s Digital Performer audio sequencer
software, the foot switch triggers the 3 key on the
numeric keypad, which toggles recording in
Digital Performer. Therefore, pressing the foot
switch is the same as pressing the 3 key. The
828mk3 Control Panel software lets you program
any keystroke you wish.
Hybrid FireWire/USB2 connectivity
FireWire has long been recognized as a reliable,
high-performance connectivity standard for
professional MOTU audio interfaces. Meanwhile,
high-speed USB2 has also developed into a widely
adopted standard for connecting peripheral
devices to personal computers.
To fully support both formats, your 828mk3
Hybrid audio interface is equipped with both
FireWire B (400 Mbit/sec) connectors and a
high-speed USB2 (480 Mbit/sec) connector, and
you can use either port to connect the 828mk3 to
your computer.This gives you maximum flexibility
and compatibility with today’s ever-expanding
universe of Mac and Windows computers.
THE 828MK3 FRONT PANEL
Mic/guitar inputs with preamps
The two mic/instrument inputs (front panel and
rear panel) are equipped with preamps and
“combo” XLR/TRS jacks, which accept XLR
microphone inputs or quarter-inch guitar/
instruments inputs. Individual 48 volt phantom
power and a 20 dB pad can be supplied
independently to each mic input. The Precision
Digital Trim™ knobs on the front panel for each
mic/instrument input provide up to 53 dB of boost
in precise 1 dB increments.
As explained in “Mic/guitar sends” on page 11, the
pre-amplified signal can be routed to external
outboard gear before being routed back into the
828mk3.
Mic/guitar input overload protection
Both mic/guitar inputs are equipped with
V-Limit™, a hardware limiter that helps prevent
digital clipping from overloaded input signals.
With V-Limit enabled, signals can go above zero
dB (with limiting applied) to as high as +12 dB
above zero with no distortion due to digital
clipping.
Additional or alternative protection can be applied
to the mic/guitar inputs by enabling the 828mk3’s
Soft Clip feature, which engages just before
clipping occurs and helps reduce perceptible
distortion.
Headphone output and main volume control
The 828mk3 front panel provides two independent
headphone jacks with independent volume knobs,
one of which also controls the XLR main outs on
the rear panel.Alternately, this MASTER VOL
knob can be programmed to control any
combination of outputs (analog or digital). For
example, it can control monitor output for an
entire 5.1 or 7.1 surround mix.
!828mk3 Hyb Manual/Win Page 12 Monday, March 28, 2011 6:11 PM

ABOUT THE 828MK3
13
Programmable backlit LCD display
Any 828mk3 setting, including the powerful
CueMix FX on-board 16-bus mixer with effects,
can be accessed directly from the front panel using
the four rotary encoders and the 2x16 backlit LCD
display.
Metering section
The front panel of the 828mk3 displays several
banks of input and output metering.The threshold
for these lights is approximately -42 dB. The four-
and five-segment input meters provide dedicated
multi-segment metering for their respective inputs,
as do the five-segment main out meters.
Two ten-segment meters for the two front-panel
mic/guitar inputs show input levels from -42 to -1
in the first column of LEDs, plus an additional
range in a second column from zero to +12 dB
(including clip). Both inputs are equipped with V-
Limit™,a hardware limiter.With the limiter turned
off, signals that hit zero or above will clip (a hard
digital clip). However, with V-Limit turned on,
signals can go as high as +12 dB above zero with no
digital clipping. If the signal then goes above +12
dB, it will clip, even with V-Limit engaged.
The
Clock lights indicate the global sample rate (as
chosen in the MOTU Audio Console software).
The LOCK and TACH LEDs provide feedback for
the 828mk3’s on-board SMPTE synchronization
features.TheADAT and MIDI LEDs indicate audio
and MIDI activity, respectively.
16-BIT AND 24-BIT RECORDING
The 828mk3 system handles all data with a 24-bit
signal path, regardless of the I/O format.You can
record and play back 16-bit or 24-bit audio files at
any supported sample rate via any of the 828mk3’s
analog or digital inputs and outputs. 24-bit audio
files can be recorded with any compatible host
application that supports 24-bit recording.
CUEMIX FX 32-BIT FLOATING POINT
MIXING AND EFFECTS
All 828mk3 inputs and outputs can be routed to the
on-board CueMix FX 16-bus (8 stereo) digital
mixer driven by hardware-based DSP with 32-bit
floating point precision. The mixer allows you to
apply no-latency effects processing to inputs,
outputs or busses directly in the 828mk3 hardware,
independent of the computer. Effects can even be
applied when the 828mk3 is operating stand-alone
(without a computer) as a complete rack-mounted
mixer. Input signals to the computer can be
recorded wet, dry, or dry with a wet monitor mix
(for musicians during recording, for example).
Effects include reverb, parametric EQ and
compression/limiting. The 828mk3’s Classic
Reverb™ provides five different room types, three
frequency bands with adjustable crossover points,
shelf filtering and reverb lengths up to 60-seconds.
Two forms of compression are supplied: a standard
compressor with conventional threshold/ratio/
attack/release/gain controls and the Leveler™, an
accurate model of the legendary LA-2A optical
compressor, which provides vintage, musical
automatic gain control.
CueMix FX also provides 7-band parametric EQ
modeled after British analog console EQs,
featuring 4 filter styles (gain/Q profiles) to
effectively cover a wide range of audio material.
Low-pass and high-pass filters are also supplied
with slopes that range from 6 to 36 dB. The EQ
employs extremely high precision 64-bit floating
point processing.
The 838mk3’s flexible effects architecture allows
you to apply EQ and compression on every input
and output (a total of 58 channels), with enough
DSP resources for at least one band of parametric
EQ and compression on every channel at 48 kHz.
However, DSP resources are allocated dynamically
and a DSP meter in the CueMix FX software

(included) allows you to keep tabs on the 828mk3’s
processing resources. Each input, output and mix
bus provides a send to the Classic Reverb
processor, which then feeds reverb returns to mix
busses and outputs, with a selectable split point
between them to prevent send/return feedback
loops.
HOST AUDIO SOFTWARE
The 828mk3 ships with standard Windows drivers
that allow you to record, edit, play back, and mix

CONNECT THE 828MK3 INTERFACE
Your 828mk3 Hybrid audio interface is equipped
with both FireWire B connectors (400 Mbit/sec)
and a high-speed USB2 connector (480 Mbit/sec),
and you can use either port to connect the 828mk3
to your computer. This gives you maximum
flexibility and compatibility with today’s ever-
expanding universe of Mac and Windows
computers.
Type B FireWire ports
The 828mk3 Hybrid has two FireWire Type B
ports, which provide the most reliable FireWire
connection available. The ports operate at 400
Mbit/s, and they can be connected to any available
FireWire port on your computer, either Type A or
Type B. If your computer has FireWire Type B
ports, use the included 9-pin-to-9-pin FireWire
cable. If your computer has either standard Type A
ports or miniature Type A ports, use the
appropriate 9-pin-to-6-pin or 9-pin-to-4-pin
FireWire cable (sold separately).
Should I use FireWire or USB 2.0?
If your computer does not have a FireWire port,
then obviously you will need to connect the
828mk3 Hybrid to one of its high-speed USB 2.0
ports.
If your computer has both FireWire and USB2,
then it is your choice, and your decision may
depend mostly on other peripherals you may have.
!828mk3 Hyb Manual/Win Page 19 Monday, March 28, 2011 6:11 PM

INSTALLING THE 828MK3 HARDWARE
20
If you are connecting via FireWire
1Before you begin, make sure your computer and
the 828mk3 are switched off.
2Plug one end of the 828mk3 FireWire cable
(included) into the FireWire socket on the
computer.
3Plug the other end of the FireWire cable into the
828mk3 as shown below in Figure 4-1.
Figure 4-1: Connecting the 828mk3 to the computer via FireWire.
☛Make absolute sure to align the notched side
of the FireWire plug properly with the notched side
of the FireWire socket on the 828mk3. If you
attempt to force the plug into the socket the wrong
way, you can damage the 828mk3.
High Speed USB 2.0 versus USB 1.1
There are primarily two types of USB host
controllers widely available on current personal
computers. USB 1.1 controllers support simple
peripherals that don’t require a high speed
connection, such as a computer keyboard, a
mouse, or a printer. USB 2.0 controllers support
high speed devices such as the 828mk3. Since the
828mk3 requires a high speed connection, it must
be connected to a USB 2.0 host controller or hub.
For the most reliable connection, it is
recommended that you connect the 828mk3
directly to one of your computer’s USB 2.0-
compatible ports. However, since USB 2.0 hubs are
compatible with both types of devices, the 828mk3
can be connected to a USB 2.0 hub along with USB
1.1 devices if necessary. The 828mk3 will not
operate properly if it is connected to a USB 1.1 hub.
Follow these instructions to determine whether
your computer supports USB 1.1 or USB 2.0:
Windows 7 and Vista
1Open the Windows Control Panel, and choose
Hardware and Sound.
2In the Devices and Printers section,click Device
Manager.
