Getting Started
Channel Setup
1. Before following the ‘Getting Started’ section of this
manual, be sure to install the Helix Board’s driver
on your PC or Mac. Mac users do not require a
driver when using the FireWire interface, however
instructions on setting the unit up on a PC can be
found on page 13.
2.
Ensure all power is turned off on your mixer. To
totally ensure this, the AC cable should not be
connected to the unit.
3.
All faders and level controls should be set at the
lowest level and all channels switched off to ensure
no sound is inadvertently sent through the outputs
when the device is switched on. All levels can be
altered to acceptable degrees after the device is
turned on.
4.
Plug all necessary instruments and equipment into
the device’s various inputs as required. This may
include line signal devices, such as keyboards and
drum machines, as well as microphones and/or
guitars, keyboards, etc.
5.
Plug any necessary equipment into the device’s
various outputs. This could include ampliers and
speakers, monitors, signal processors, and/or
recording devices.
6.
Plug the supplied AC cable into the AC inlet on the
back of the device and a power outlet of a suitable
voltage.
7.
Turn the power switch on.
8.
Consult the FireWire / USB section of this manual
for more information on its setup and usage. When
connecting the Helix Board to the computer, be
sure to turn the computer on rst, then connect the
FireWire or USB cable and turn the Helix Board
on.
1. To ensure the correct audio level of the input
channel is selected, each of the Mixer’s Channel’s
ON buttons should be disengaged (which should
turn the corresponding LED indicator off), as well
as the Solo buttons on each channel and all buttons
in the Control Room Source section, with exception
to the Main L/R button.
2.
Ensure the channel you wish to set has a signal
sent to it similar to the signal that will be sent when
in common use. For example, if the channel has a
microphone connected to it, then you should speak
or sing at the same level the performer normally
would during a performance; if a guitar is plugged
into the channel, then the guitar should also be
strummed as it normally would be (and so on). This
ensures levels are completely accurate and avoids
having to reset them later.
3.
Move the Channel fader and Master fader to around
the 0 dB mark.
4.
Turn the Channel ON.
5.
Pushing the channel’s Solo button and releasing
the Pre/Post button on the CTRL RM section will
send the pre-fader signal of the activated channel
to the Control Room / Phones mixing bus and the
Level Meter will display the Control Room’s signal
properties.
6.
Set the gain so the level meter indicates the audio
level is around 0 dB (it is advisable to never let the
level exceed 7 dB).
7.
This channel is now ready to be used; you can stop
making the audio signal.
8.
You can now repeat the same process for other
channels if you wish.

Making Connections
Inputs and Outputs
1. XLR Microphone Jacks
These jacks accept typical 3-pin XLR inputs for
balanced and unbalanced signals. They can be used in
conjunction with microphones – such as professional
condenser, dynamic or ribbon microphones – with
standard XLR male connectors, and feature low
noise preampliers, serving for crystal clear sound
replication. The Helix Board 18 Universal features a
total of eight Microphone inputs.
NB. When these inputs are used with condenser microphones, the
Phantom Power should be activated. However, when Phantom Power
is engaged,single ended (unbalanced) microphones and instruments
should not be used on the Mic inputs.
2. Line Inputs
This input accepts typical 1/4” TRS (balanced) or
TS (unbalanced) inputs, for balanced or unbalanced
signals. They can be used in conjunction with a wide
range of line level devices, such as keyboards, drum
machines, electric guitars, and a variety of other
electric instruments.

3. Stereo Channels
The Helix Board 18 Universal also
features a few stereo channels, thrown
in for maximum exibility. Each of these
stereo channels features two 1/4” phone
jacks, for the addition of various line
level input devices, such as electronic
keyboards, guitars and external signal
processors or mixers, as well as XLR
Microphone jacks on channels 7/8 and
9/10, allowing users to option of using the
channel as a microphone input channel.
If you wish to use a monaural device on
a stereo input, simply plug the device’s
1/4” phone jack into the left (mono) input
and leave the right input bare. The signal
will be duplicated to the right due to the
miracle of jack normalizing.
3
4. AUX Returns
These 1/4” TS inputs are for the return of audio to
the Helix Board 18 Universal mixer, processed by an
external signal processor. If really needed, they can
also be used as additional inputs. The feed from these
inputs can be adjusted using the AUX Return controls
on the face of the mixer. When connecting a monaural
device to the AUX Return 1 and 2 inputs, simply plug
a 1/4” phone jack into the left (mono) input, and the
signal will appear in the right as well.
4
5. AUX Sends
These 1/4” TRS outputs may be used to connect to
an external signal processor, or even to an amplier
and speakers (depending on your desired settings)
from the mixer. The signal from the AUX Sends is
controlled by the AUX master controls (on the face
of the mixer), which obtain their signal from the AUX
controls located on each channel strip. The Helix
Board 18 Universal features a total of 3 AUX Sends.
When using the FireWire or USB interface, AUX Send
1 can be elected to receive the audio signal sent from
the Computer, for monitoring or recording purposes.
6. Phones
This stereo output port is suited for use with
headphones, allowing monitoring of the mix. The
audio level of this output is controlled using the Control
Room / Phones control.
7. Record Out
These outputs will accommodate RCA cables, able to
be fed to a variety of recording devices. Also included is
a mini stereo jack for the addition of recording devices
such as MD players, and even laptop computers.
8. 2T Return
These RCA inputs are used to connect the mixer with
parallel external devices, such as sub mixers or CD,
Tape and Cassette Players. Also included are mini
stereo jacks, for receiving signals from audio devices
like portable CD, MD and MP3 players.

9. Main Outputs
These two 1/4” TRS balanced jacks will output the
nal stereo line level signal sent from the main mixing
bus. The primary purpose of these jacks is to send the
main output to external devices, which may include
power ampliers (and in-turn, a pair of speakers),
other mixers, as well as a wide range of other possible
signal processors (Equalizers, Crossovers, etcetera).
10. Group Outputs
These balanced 1/4” TRS phone jacks output the nal
feed from the Group 1 and 2 mix controlled by the
Group level faders. These outputs can be used to
feed a wide range of devices, such as mixers, signal
processors, and even to connect an amplier and
speakers to be used along with the Main Speakers,
for a more rounded audio experience.
12. Control Room Outputs
These two 1/4” phone jack outputs feed the signal
altered by the Control Room / Phones level control on
the face of the mixer. This output has extensive use,
as it can be used to feed the signal from the mixer to
an active monitor, for the monitoring of the audio signal
from within a booth, or, alternatively, for the addition
of external signal processing devices or mixers, as
well as acting as a “side ll” output, supplying audio
to indoor areas that the main speakers do not reach.
When using the FireWire or USB interface, this output
can be elected to be fed the audio signal from the
Computer, for monitoring of recording audio.
13. Foot Switch Jacks
These ports are for the inclusion of an unlatched foot
switch, used to remotely adjust properties of the builtin Digital Effect processor. The jack on the right is used
to turn the Digital Effects on and off, whereas the jack
on the left is used for adjusting tap delay properties.
Rear Panel
11. Channel Inserts
Located on the rear of the Helix Board 18 Universal,
the primary use for these TRS phone jacks is for
the addition of external devices, such as dynamic
processors or equalizers, to mono input channels 1
through to 6. This will require a Y cord that can send
(pre-fader and pre-EQ) and receive signals to and
from an external processor. The tip of the TRS plug
is for sending of the signal to the external device, the
ring is for return of the signal to the Helix Board 18
Universal, and the Sleeve is the grounding.
13
14. Main XLR Outputs
These two XLR ports will output the nal stereo line
level signal sent from the main mixing bus. The primary
purpose of these jacks is to send the main output to
external devices, which may include power ampliers
(and in-turn, a pair of speakers), other mixers, as well
as a wide range of other possible signal processors
(equalizers, crossovers, etcetera).

15. S/PDIF Output
This RCA S/PDIF (Sony / Phillips Digital Interface) jack
is for the output of digital audio signals, allowing the
Main L&R audio from the mixer to be passed to another
device without having to convert the signal from digital
to analog and back again. The output sampling rate
is permanently set to 44.1 kHz per second when no
FireWire or USB connection is made. If a FireWire /
USB connection is established between the unit and
computer, then the S/PDIF output sampling rate will
be the same as that set by the Helix Board Control
Panel software.
16. FireWire / USB Connections
The two FireWire connectors and the single USB
connector are for linking the Helix Board 18 Universal
to a PC or Macintosh computer. It will allow 16
channels to be streamed to the computer (the amount
of channels you are able to record simultaneously
depends on the DAW software used), and 2 audio
channels of the computer to be returned to the mixer.
Please observe the FireWire / USB section of this
manual for more information.
17. Power Connector
This port is for the addition of a power cable, allowing
power to be supplied to the mixer. Please use the
power cable that is included with this mixer only. The
Helix Board 18 Universal features a switching power
supply, suitable for all zones.
Controls and Settings
Rear Panel
18. Phantom Power Switch
When this switch is in the on position, it activates
+48V of phantom power for all microphone inputs,
allowing condenser microphones (well, the ones that
don’t use batteries) to be used on these channels.
Activating Phantom Power will be accompanied
by an illuminated LED above the left channel Level
Meter. Before turning Phantom Power on, turn all
level controls to a minimum to avoid the possibility of
a ghastly popping sound from the speakers.
NB. Phantom Power should be used in conjunction with balanced
microphones. When Phantom Power is engaged, single ended
(unbalanced) microphones and instruments should not be used
on the Mic inputs. Phantom Power will not cause damage to most
dynamic microphones, however if unsure, the microphone’s user
manual should be consulted.
19. Power Switch
This switch is used to turn the mixer on and off. Ensure
you turn all level controls down before activating.
Channel Controls
20. Low Cult Filter (75 Hz)
This button will activate a high-pass lter that reduces
all frequencies below 75 Hz at 18 dB per Octave,
helping to remove any unwanted ground noise or
stage rumble. On stereo channels 7/8 and 9/10, the
low cut lter affects only the XLR Microphone inputs
(and not the line inputs).
21. Line/Mic Gain Control
This controls the sensitivity of the input signal of the
Line/Microphone input. The gain should be adjusted
to a level that allows the maximum use of the audio,
while still maintaining the quality of the feed. This can
be accomplished by adjusting it to a level that will
allow the peak indicator occasionally illuminate.
22. High Frequency Control
This control is used to give a shelving boost or cut of
±15 dB to high frequency (12 kHz) sounds. This will
adjust the amount of treble included in the audio of
the channel, adding strength and crispness to sounds
such as guitars, cymbals, and synthesizers.
23. Middle Frequency Control
This control is used to provide a peaking style of boost
and cut to the level of middle frequency sounds at a
range of .±15 dB. These mixers also provide a sweep
control, allowing you to select a center frequency
between 100 Hz and 8 kHz. Changing middle
frequencies of an audio feed can be rather difcult
when used in a professional audio mix, as it is usually
more desirable to cut middle frequency sounds rather
than boost them, soothing overly harsh vocal and
instrument sounds in the audio.
Stereo channels 11/12 and 13/14 of the Helix Board
18 Universal feature a High-Mid and Low-Mid control
instead of the typical controls described above. They
provide a peaking style of boost and cut to middle
frequencies, where the frequencies are set at 3 kHz
and 800 Hz (High-Mid is set at 3 kHz and Low-Mid is
set at 800 Hz). Stereo channels 9/10 and 11/12 have
a single Middle Frequency control, with the center
frequency set at 2.5 KHz.
24. Low Frequency Control
This control is used to give a shelving boost or cut
of +/-15dB to low frequency (80Hz) sounds. This will
adjust the amount of bass included in the audio of the
channel, and bring more warmth and punch to drums
and bass guitars.

27. EFX Control
This control alters the signal level that is sent to the
EFX send (AUX 3) output and the built-in digital
effect processor. The EFX send signal can be used in
conjunction with external signal processors (this signal
of which can be returned to mixer via the AUX return
input), or simply as an additional auxiliary output.
28. Pan / Balance Controls
This alternates the degree or level of audio that the
left and right side of the main mix should receive. On
mono channels, the PAN control will adjust the level
that the left and right should receive (pan), where as
on a stereo channel, adjusting the BAL control will
attenuate the left or right audio signals accordingly
(balance).
29. On Button and Indicator
This turns the channel on, allowing the user to use the
feed from the channel’s inputs to supply the MAIN L/R,
GROUP 1/2, AUX and EFX buses. The corresponding
indicator will be illuminated when turned on.
30. 1-2 and L-R Buttons
These handy buttons allow you to decide the audio
path of the corresponding channel. Pushing the “1/2”
button allows the signal to be sent to the Group 1/2
mix, where the “L-R” allows it to be sent to the Main
L/R mix.
30
31
33
32
25. FireWire / USB Pre/Post Switch
This switch is used to change the signal of the
corresponding channel that is sent to the Computer
via the FireWire or USB interface between that of a
pre-EQ, pre-fader, pre-low cut and that of a post-EQ,
post-fader, post-low cut. In the upper-most position,
the channel will be pre, and in the lower position
post.
26. AUX Controls
These controls alter the signal level that is being sent
to the auxiliary 1 and 2 mixes. The signals of these
mixes are suitable for connecting stage monitors,
allowing artists to listen to the music that is being
played. Also included is a Pre/Post button, which
alternates the feed to the AUX 2 mix between a post
and pre-fader feed.
31. Peak Indicator
This LED indicator will illuminate when the channel
hits high peaks, 6 dB before overload occurs. It is best
to adjust the channel level control so as to allow the
PEAK indicator to light up on regular intervals only.
This will ensure a greater dynamic range of audio.
This indicator also doubles as a Solo indicator, when
the Solo button is engaged.
32. Solo Button
The Solo button is pushed to allow the signal of a
corresponding channel to be sent to the Control Room
/ Phones control (pre or post fader, depending on the
properties selected by the pre / post button, located
by the Control Room / Phones control), for use with
either headphones or studio monitors. This also allows
easier setting of the input gain and tracking of audio by
sound engineers. The Peak indicator above the Solo
button also doubles as a Peak Indicator, illuminating
when the signal reaches high peaks.
33. Channel Level Control (Fader)
This control will alter the signal level that is sent from
the corresponding channel to the appropriate mixing
buses (whether they are the MAIN L/R or AUX).
Helix Board 18 Universal

34. +4 / -10 Buttons
These buttons, located on each stereo
input channel, are used adjust the input
sensitivity of the corresponding channel,
which will adapt the mixer to external
devices which may use different
operating levels. If the input source is 10 dBV (consumer audio standard), it is
best to engage the switch, allowing the
signal to be heard. If the input source is
+4 dBu (professional audio standard)
the corresponding input channel’s button should
be disengaged to ensure the integrity of the Mixer’s
circuitry. If you are unsure of the source’s operating
level, we suggest leaving the switch disengaged until
you test the source’s signal. You can then engage if
necessary (if the level of input is obviously too low).

Digital Effect Section
35. Digital Effect Display
This 2-digital numeric display shows the program
number that is currently applied to your EFX audio
signal. When you rotate the Program control, you can
scroll through different program numbers; however
the display will revert back to the original program if a
new program is not selected within a few seconds. For
a list of available effects, please observe the Digital
Effect Table.
36. Sig and Clip Indicators
Located within the Digital Effect Display are Clip
and Sig LEDs. The Sig LED will light up when any
signal is received by the effect processor, and the
Clip LED will light up shortly before excessive signals
are dynamically clipped. If the Clip LED lights up too
often, it may be advisable to turn down the AUX 3/
EFX master control to ensure the signal level is not
excessive.
37. Program Control
This control is used to scroll through the various
effects. Turning the control clockwise will allow users
to ascend into higher program numbers, and turning
it counter-clockwise will allow users to descend into
lower program numbers. When turning to a new
program, a small LED will ash until you push the
program knob down – this will apply the effect. When
a tap-delay effect is selected, pressing this control will
allow users to select the tap-delay time.
By pushing the button several times, the effect
processor interprets the time between last two pushes
and remembers this as the delay time – until the button
is pushed again. This is kept even after the power is
turned off. When the tap delay effect is selected, a
small LED (located between the two digit display) will
ash within the digital effect display window at the
selected intervals.

37
38
38. Effect Bypass
Use it to bypass the effects and monitor your audio
before and after the effect is applied. When the effect
engine is bypassed, the 2 small indicators on the
digital effect display will ash.
39. AUX 3 / EFX Send Control and Solo Button
This rotary control will adjust the level of the output
signal at the AUX 3 send jack, as well as determine
the amount of audio the built-in effects processor
will receive. When this control is set to it’s minimum
position, neither the AUX 3 send nor the effect
processor will receive a signal. The accompanying
Solo button allows the EFX Send signal to be sent to
the Control Room / Phones mix.
40. To Main Control
The “to Main” control will allow users to adjust the
processed signal that is sent to the Main.
41. To AUX 1/2 Controls
These controls allow users to send the signal
processed by the effects processor to the AUX 1 or
2 mix, allowing for monitoring of the signal. This is
called “Effect to Monitor.”
Master Section
42. AUX Send Controls and Solo Buttons
These two controls are for adjusting the audio level
that is sent to the corresponding AUX outputs, the
signal of which is initially taken from each channel’s
individual AUX send controls. Pushing one of the
accompanying Solo buttons will send the
corresponding AUX signal to the Control
Room / Phones mix (pre or post fader,
depending on the Pre / Post button).
43. FireWire / USB Trim Control
The FireWire / USB trim control can be
used to adjust the level of the outgoing
FireWire or USB signal (which will be
received by the computer) from the AUX
2/3, Group 1/2 or Main L/R (depending
on the FireWire / USB Select switch).
If the input signals received by your
computer are noticeably excessive, using this control
could help to attenuate the signal to an acceptable
degree.

display properties of the Solo signal, which is helpful
with setting of channel properties. If Solo indicator
illuminates green, this means the Solo feed is a prefader signal. If the Solo indicator illuminates red, the
feed is post-fader. If the no Solo buttons are activated,
the Control Room source signal properties are
displayed by the Level Meter.
50. Control Room Source Buttons
This set of buttons allows users to select which signals
they wish to send to the Control Room / Phones output.
There is a button each for the FireWire / USB, Group
1-2, 2T Return and Main mixes. These signals can be

the mixer is on.
49. Level Meter
This dual 12 segment level meter gives an accurate
indication of when audio levels of the Main L/R output
reach certain levels. The 0 dB indicator illuminates
is approximately equal to an output level of +4 dBu
(balanced), and the PEAK indicator illuminates just
before the signal is dynamically clipped. It is suggested
that users set the various levels controls so that the
level sits steadily around 0 dB to make full use of
audio, while still maintaining fantastic clarity.

51. Control Rooms / Phones Level Control
This rotary control will allow users to adjust the audio
level of the Control Room / Phones signal (received
by solo signal, or as chosen in the Source Select
buttons).
52. Control Room Pre / Post Button
The Pre / Post button alters the Solo signals received
by the Control Room / Phones mix between Post and
Pre fader signals. When set to Post, the Solo Indicator
will light up red; when set to Pre, the Solo Indicator will
light up green (channel level set).
53. 2T Return Control and To Main Button
Use this rotary control to adjust the signal level
received through the RCA 2T Return inputs. The To
Main button allows users to send the 2T Return signal
to the main mix.

2 outputs. These faders can be fed a signal from the
various mono and stereo channels, as well as EFX
Returns, depending on your selections. When pushed
all the way up, these faders provide 10 dB of gain to
the signal, and, when set all the way down, effectively
mute the signal.
The Group Controls also feature Left and Right
buttons, which allow you to send the Group 1/2 signal
to the Main Left and Right mix.
57. Main L/R Faders
These two faders are the nal level control for the
Main Left and Right audio feeds, sent to the Main L
and R outputs. These faders are possibly fed by the
various mono and stereo channels, as well as AUX
and EFX returns and 2T inputs, depending on the your
selections. When pushed all the way up, these faders
provide 10 dB of gain to the signal, and, when set all
the way down, effectively mute the signal.

Cubase LE 4 is a fairly powerful digital audio workstation program provided along with the Helix Board
18 Universal mixer that allows users to record, edit,
delete, and alter their tracks. Please note that only 8
tracks can be recorded at once with the version of Cu-
base included, and users must upgrade or nd other
suitable DAW software if they choose to record more
tracks.
Installation
Insert the Cubase LE installation CD that came with
your mixer into the CD drive of your computer. Run
the installer. When the installation is complete, run
Cubase and follow the onscreen instructions to activate the program. Users must sign up to Steinberg’s
MySteinberg service to obtain an activation code.
Setup
After successfully completing the installation process,
the following process must be followed to work efciently with the Helix Board 18 Universal mixer.
1. Open the Cubase LE program.
2. Go to the ‘Devices’ pull-down menu and select ‘De-
vice Setup’. On the left, select ‘VST Multitrack’.
3. From the ASIO Driver drop-down list select the
“Phonic ASIO Driver”. A pop-up box will ask you if
you want to switch the ASIO driver. Click ‘Switch’.
This completes the basic installation and setup.
4. To activate audio tracks received from the Helix
Board mixer, complete the following two steps.
a. Go to the “devices” pull-down menu and select
‘VST Inputs’. This will display the various inputs
(“HB 18 U Ch 1”, “HB 18 U Ch 2”, etc.)
b.
Activate 8 of these channels by clicking the
“Active” button located next to each channel
name. Please note, only 8 input channels can
be activated at any one time. This is a limitation
of Cubase LE, and if more input channels are
needed, we suggest upgrading to a higher version of Cubase, or use other DAW software.
5. For further instructions on the operation of Cubase,
please consult the user manual by pressing F1
while the program is open.
Helix Board 18 Universal
If you wish to reset the Helix Board 18 Universal ASIO
driver for any reason, simply go to the ‘devices’ pulldown menu and select ‘device setup’. Click “reset”
and select the “Phonic ASIO Driver.” Click ‘ok’ to continue and the connection to the Helix Board 18 Universal should reset.
17
Helix Board Control Panel
The Helix Board Universal control panel can be accessed at any time by entering choosing the shortcut
from your Programs menu. This program will not only
allow users to alter their device and channel names
and properties, but will also let them correct for latency issues, change sampling rates, and so forth.
When opening the software, a number of options will
be available for users to select from, allowing them to
adjust the available properties.
Devices
In the Devices section, users are able to view and edit
the name of the Phonic Devices connected to their
computer.
Output Channels
By entering the Output Channels section, users can
view and edit the names of the two output channels
from the computer to the Helix Board 18 Universal
mixer.
Synchronization
In the Synchronization section, users can adjust the
sampling rate and other synchronization properties.
Many of these adjustable properties, as they are, are
set for optimum performance and, unless you are sure
of what you need to change, are probably best left
alone.
Input Channels
The Input Channels section allows users to view and
edit the name of the various input channels received
from the FireWire / USB input. For a list of default
channel names, please consult the table on page 17.
First off, the synch mode can be altered, though making this alteration is not recommended for novice users. The synch mode is basically the way the computer determines what the ‘clock source’ (ie. device
that your computer will use to determine the timing of
all digital signals received) will be. The default setting
for this feature is “CSP”, meaning the Helix Board 18
Universal is the “master” clock source of the device.
The other options allow users to make the Helix Board
18 Universal follow the “timing” of whichever device
is the clock source. Having two clock sources has
the potential to create very undesireable audio, so it
should be avoided. If the Helix Board 18 Universal is
the only piece of digital audio equipment attached to
the computer, there is no reason this option should be
changed.
18 Helix Board 18 Universal
Users are also able to change between automatic
and manual sampling rate settings. When the sampling rate is manually set, users can select between
sampling rates of 44.1, 48.0, 88.2 and 96.0 kHz per
second. Many devices have sampling rates that do
not surpass 44.1 kHz per second, therefore, when using multiple digital devices, users are advised not to
exceed this level unless they are sure the secondary
device’s sampling rate can .
Settings
Users are able to adjust various buffer times in the
Settings section.
The Stream Buffer Depth is adjustable between 0.5
and 20 milliseconds. It adjusts the buffer used when
streaming a signal from the Helix Board 18 Universal.
If the depth is set too high, an obvious latency will
become evident. If the depth is too low, various clicks
and pops may become obvious. It is best to set the
Stream Buffer Depth to a level that allows users to get
the lowest latency, while still maintaining an optimal
performance. The default settings are ideal for most
computers.
Streams
In the Streams section, the Helix Board 18 Universal
device properties can be viewed. Each input and output stream can be scrutinized, and the isochronous
stream number and its supported sampling rates can
be viewed.
The ASIO Buffer Depth is adjustable between 4 and
40 milliseconds. This allows users to adjust the latency of the stream received by ASIO driver-based
software (including Steinberg Cubase LE).
The WDM (Windows Driver Model) Sound Buffer
Depth is adjustable between 4 and 40 milliseconds.
This allows users to adjust the latency of the stream
received by WDM based programs.
Also in this section, users are able to view their
“drop out statistics”, where the number of times the
FireWire / USB connection has been interrupted can
be viewed.
