4 Helix Board 24 Universal
INTRODUCTION
Thank you for purchasing the Helix Board 24 Universal, one
of Phonic’s newest mixers that sounds great and works hard
both in the studio and on the road. The mixer features a USB
and FireWire interface that can stream up to 18 independent
channels of audio to the computer and return two tracks
for monitoring, all at a 24-bit bit-rate and 96 kHz sampling
rate. Also featured is an onboard 32/40-bit digital multi-effect
processor providing 100 popular programs plus tap delay, testtones and foot switch jacks. The multi-directional Input/Output
pod makes the device versatile; making rack mounting or tabletop connections much easier.
There are sixteen extremely low noise Mic preamps, each with
individual phantom power, and sixteen 1/4” phone jacks spread
across the Helix Board 24 Universal 16 mono channels. Each
channel features a 3-band EQ (with a sweepable mid control),
AUX, EFX and Group sends, as well as a low-cut filter for
removing troublesome stage-rumble. Additional features include
AUX sends and returns, input and output soloing, four true
subgroups, dedicated Mono/Subwoofer output with selectable
Low Pass Filter, S/PDIF digital outputs, Steinberg Cubase LE
workstation software and an included rack-mounting kit.
We know how eager you are to get started – wanting to get
the mixer out and hook it up to your computer is probably your
number one priority right now – but before you do, we strongly
urge you to take a look through this manual. Inside, you will
nd important instructions and warnings on the set up, use and
application of your brand new Helix Board 24 Universal. If you
do happen to be one of the many people who flatly refuse to
read user manuals, then we just urge you to at least glance at
the Instant Setup and FireWire Interface sections. After glancing
at or reading through the manual (we applaud you if you do read
the entire manual), please store it in a place that is easy for you
to nd, because chances are there’s something you missed the
rst time around.

GETTING STARTED
1. Ensure all power is turned off on your mixer. To totally ensure
this, the AC cable should not be connected to the unit.
2. All faders and level controls should be set at the lowest level
and all channels 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 using the channel setup instructions.
3. Plug any necessary equipment into the device’s various
outputs. Thi s cou ld include ampli fiers and speake rs,
monitors, signal processors, and/or recording devices.
4. Plug the supplied AC cable into the AC inlet on the back of
the device and then into a power outlet of a suitable voltage.
5. Turn the power switch on and follow the channel setup
instructions to get the most out of your equipment.
CHANNEL SETUP
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 Maser 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 prefader 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 Jacks
These jacks accept typical 3-pin XLR
inputs for balanced and unbalanced
sig n al s. Th e y ca n be use d i n
conjun ctio n with mic rophones –
such as professional condenser,
dynamic or ribbon microphones –
with standard XLR male connectors,
and feature low noise preampliers,
ser v i n g for crystal cl e a r sound
re plica tion. The Heli x Boa rd 24
Universal features a total of sixteen
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 In Jacks
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. Insert Jacks
The primary use for these 1/4” TRS phone jacks is for the
addition of external devices, such as dynamic processors or
equalizers, to the corresponding mono input channel. This will
require a Y cord that can send and receive signals of the mixer
to and from an external processor. The tip of the TRS jack will
send the signal from the input channel, and the ring will return
the signal back to the mixer (the sleeve is the grounding).
4. Direct Outputs
These connections are for the direct output of the signals
received by mono channels 1 through to 8, post-fader, post-EQ,
post-HPF, and post-mute. They are most commonly used to
connect multitrack recorders.
5. Auxiliary (AUX) Returns
The 1/4” TRS AUX Return inputs are for the return of audio to
the Helix Board 24 Universal mixer, processed by an external
signal processor. If really needed, they can also be used as
additional stereo 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, 2 and
4 inputs, simply plug a 1/4” phone jack into the left (mono) input,
and the signal will appear in the right as well. This, however,
does not work for the AUX Return 3.
NB.When any device is plugged into the mixer’s corresponding EFX
Return inputs (AUX Return 3), the signal processed by the mixer’s
internal digital effect engine is then not fed to the Main L/R; the signal fed
into the EFX Return 3 inputs will be instead.

6. Auxiliary (AUX) Sends
These 1/4” TRS phone jacks are the final output of line-level
signal fed from the corresponding auxiliary send mixing buses,
and are best suited for use with external effect processors or
stage monitors. Feeding the output from the Auxiliary outs to
an amplifier - and possibly an equalizer - and then to a floor
monitor speaker allows artists to monitor their own instruments
or vocals whilst performing. The AUX 5 and AUX 6 Sends take
their signal directly from AUX Controls 3 and 4, when the 5/6
Shift Button is activated.
7. Group Outs
These 1/4” phone jacks output the nal feed from the Group 1,
2, 3 and 4 Faders on the main panel of the mixer. These outputs
can be used to feed multi-track records, as well as an amplier
and speakers to be used along with the Main Speakers.
8. CTRL RM (Control Room) Output
These two 1/4” Phone Jack outputs feed the signal altered by
the Control Room 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, among many other possible
uses.
9. DSP Effect Output
These ports are for the immediate output of the EFX signal,
processed by the internal effect processor, the level of which is
not determined by the AUX 3 Return / EFX control on the face
of the mixer. This can be used to send to external devices, for
monitoring purposes, or returned to a few channel on the Helix
Board 24 Universal, and routed to the AUX 1, 2, and 4 outputs
(the AUX 3 control must, of course, be turned down to avoid
forming a feedback loop), as well as the Group Outs, allowing
the processed signal to be sent to multiple destinations for
various applications.
10. Foot Switch Jacks
These ports are for the inclusion of a foot switch (non-latchable),
used to remotely adjust properties of the built-in Digital Effect
processor, to the mixer. The uppermost jack is used to turn the
device on and off, where the lower jack is used for adjusting tap
delay properties.
78910
11. Mono / Subwoofer Output
Thi s X LR a nd 1 /4 ” TRS
ou t p u t feeds a monaural
si gna l of th e M ai n L-R
signals combined or the AUX
4 signal (depending on the
Mono Source Select Switch),
the level of which is adjusted
by the accompanying level
control. Th i s is idea l for
use wit h a m on o sou n d
system, or for the addition
of a subwoofer to your set of speakers, adding more punch to
low frequency sounds at your PA or monitoring system. Also
featured is an Insert point, allowing external devices, such as a
compressor, to be used to alter the mono signal before it is fed
through the outputs.

12. Main Outputs
These outputs will output the nal stereo line level signal sent
from the main mixing bus. The primary purpose of the two XLR
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). The two 1/4”
TRS phone jacks are able to send the Main output to external
devices that may run in parallel with the mixer. This may include
additional power amplifiers, mixers, PA systems, as well as a
wide range of other possible signal processors.
13. Main Inserts
Located above each of the Main 1/4” Outputs, the primary use
for these 1/4” TRS phone jacks is for the addition of external
devices, such as dynamic processors or equalizers, to the
main L and main R signals. This will require a Y cord that can
send (pre-fader) and receive signals to and from an external
processor.
14. 2T Return
These inputs accommodate connections from RCA cables, able
to receive signals from such devices as tape and CD players.
15. Record Outputs
As with the 2T Return ports, these outputs will accommodate
RCA cables, able to be fed to a variety of recording devices.
16. 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 Helix Board 24 Universal to be passed to another device
without having to convert the signal from digital to analog and
back again. The output sampling rate is set to 44.1 kHz per
second – however, if the FireWire interface is in use, it will use the
sampling rate decided by the Helix Board control software.
17. FireWire and USB Interface and Switch
These two FireWire ports and single USB port are for connecting
the Helix Board 24 Universal to any PC or Macintosh computer.
They allow all 16 input channels, as well as an additional channel
(as decided by the FireWire Select Switch), to be sent to a PC
or Mac computer. The main stereo signal of the computer is also
returned to the Helix Board 24 Universal. The returned signal
can be utilized by selecting it in the Control Room Source section
on the face of the mixer.
The switch that accompanies these inputs is for swapping
between the FireWire and USB connectors. Put it in the
uppermost position when using USB, and the lower position
when using FireWire.
18. Power Connector and Fuse Holder
This port is for the addition of a power cable and supply,
allowing power to be supplied to the mixer. Please use the
power cable that is included with this mixer only. The Fuse
holder, located above the AC Power connector, is, of course,
for Helix Board 24 Universal fuse. If the fuse happens to blow,
16
1415
open the holder cover, and replace the fuse with a suitable
replacement (as indicated underneath the power connector).

Main Mixing Panel
19. 12V Lamp
This BNC socket allows you to attach a 12 Volt gooseneck
lamp, allowing better visibility in areas with poor light.
20. Phones Output
This output port is best suited for use with headphones, allowing
monitoring of the mix. The audio level of this output is controlled
using the Phones control on the front panel’s master section.
CONTROLS AND SETTINGS
Rear Panel
21. Power Switch
This switch is used to turn the mixer on and
off. Ensure you turn all level controls down
before activating. Activating the Power Switch
will be accompanied by an illuminated LED
located above the right Level Meter.
22. Phantom Power
By turning this switch selector to th e
ON position will activate +48V of phantom power for the
co r r e sponding microphone inputs, allowing condenser
microphones (well, the ones that don’t use batteries) to be
used on these channels. Activating the master Phantom Power
switch will be accompanied by an illuminated LED above the
left channel Level Meter. Before turning Phantom Power on,
turn the level control down of the channel you wish to activate
to a minimum and lower all master output levels, as to avoid the
possibility of a ghastly popping sound from the speakers.
NB. Phantom Power should be used in conjunction with balanced
mi crop hon es. When Phan tom Powe r is enga ged, sin gle ende d
(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.
23. Mono Output Source Select Switch and Volume Control
The rotary control to the right adjusts the nal output level of the
Mono/Subwoofer output. By using the switch on the left, users
are able to select signal they wish to send through the Mono/
Subwoofer output between the main mix and AUX 4 mix. If, for
example, there is audio in the main mix you do not wish to send
to the subwoofer, simply sending all the audio you wish to use
to the AUX 4 send and set the select switch to AUX 4.
21 22
23

24. Low Pass Filter
The mono output on the Helix Board 24 Universal includes a
Low Pass Filter (LPF) for removing high frequency sounds to
make the audio more appropriate for use with subwoofers. The
switch to the left turns the LPF on and off, and the rotary control
on the right allows users to adjust the cut-off frequency between
60Hz and 160Hz.

25. Gain Control
This controls the sensitivity of the input signal of the Line/
Microphone input of mono channels. 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 ensure the peak
indicator doesn’t light up, as specified in the channel set up
section.
26. Low Cut Filter (75 Hz)
This button, located on channels 1 through to 16, 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.
27. 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.
28. 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. The Helix Board 24 Universal mixer also provides 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.
29. Low Frequency Control
This control is used to give a shelving boost or cut of ±15 dB
to low frequency (80 Hz) 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.
30. AUX Controls
These four AUX controls alters the signal level that is being
sent to the auxiliary 1 to 4 mixing buses, the signal of which is
suitable for connecting stage monitors, allowing artists to listen
33
to the music that is being played, or to fed to an external effect
processors. AUX 1 and 2 feature a Pre/Post button, which
alternates the feed to the AUX mixing bus between a post and
pre-fader feed. AUX 3, on the other hand, acts as an EFX send
for the internal effect processor, or simply as an Auxiliary output.
Both the AUX 3 (EFX) and AUX 4 controls are post fader and
are sent directly to the corresponding outputs.
31. Pre/Post Switch Selector
AUX 1 and 2 feature a Pre/Post button, which alternates the
feed to the AUX mixing bus between a post and pre-fader feed.
32. 5/6 Shift Button
This button changes the routing of the AUX 3 and 4 controls,
allowing the channel’s signal to be directly output through the
AUX 5 and 6 outputs respectively.
33. Pan Controls
This alternates the degree or level of audio from that particular
channel that the left and right side of the main mix should
receive.
34. On Button and Indicator
This turns the channel on, allowing
the user to use the feed from the
chann el’s inp uts to sup ply the
MAIN L/R, GROUP 1/2, GROUP
3/4 , AUX and EFX buses (as
specified by the user, of course).
The corresponding indicator will
be illuminated when turned on.
35. Signal Indicator
This LED indicator shows when
the input level reaches -20 dBu,
basically showing when a signal
is received by the corresponding
channel.
36. 1-2, 3-4 and L-R Buttons
These handy buttons allow you to decide the audio path of the
corresponding channel. Pushing the “1/2” or “3/4” buttons allows
the signal to be sent to the Group 1/2 or 3/4 mixes respectively,
where the “L-R” allows it to be sent to the Main L/R mix.
37. 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.
38. Solo Button
The Solo but t o n is pu sh e d to al lo w th e si g na l of th e
corresponding channel to be sent to the Control Room / Phones
mixing bus (pre or post fader, depending on the properties
selected by the pre / post button, located below the solo level
control), for use with either headphones or studio monitors.
This button also allows for easier isolation of individual channel
signals, ensuring setting of the input gain or tracking of audio
by sound engineers is made simpler. The Peak indicator (above
the Solo button) also doubles as a Solo Indicator, illuminating
when the signal reaches high peaks.
39. Channel Level Control (Fader)
This 60 mm fader will alter the signal level that is sent from the
corresponding channel to the corresponding mixing buses.

Digital Effect Engine
40. Digital Effect Display
Th i s 2- d ig it al nu m e ri c
display shows the program
number t hat is currently
applied to your EFX audio
signal. When you rotat e
t h e Pr og ra m co nt ro l ,
you ca n sc ro l l t h r ou g h
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.
41. 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.
42. 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 flash until you push the
program knob down – this will apply the effect. When a tapdelay 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.

44. AUX Return 1 to 4 Controls and Solo Buttons
These controls adjust the signal level of audio fed through to the
stereo AUX Return inputs. The “To AUX Send 1” and “To AUX Send
2” controls adjust the pre-fader level of the signal from the AUX
Return controls to the corresponding AUX mixing buses for effectto-monitor sends. The AUX 3 control typically adjusts the signal
level of audio fed through to stereo AUX Return 3 inputs, however,
if no device is plugged into the AUX Return 3 inputs, it then acts as
the output level control of the built-in Digital Effect Engine.
45. Main L/R - Group Buttons
The first of these buttons changes the destination of the signal
sent from the AUX Return 3 mixing buses between the Main L/R
and Group mixing buses. The second button works when the user
selects to send the signal “To Group”, allowing the signal to be sent
to either Group 1-2 or Group 3-4.
46. C-R / PHNS Only Button
The “Control Room / Phones Only” button that is located below
AUX Return Control 4 allows users to send the AUX Return 4
post-fader signal to the Control Room / Phones mixing bus for
monitoring purposes.

47. Solo Return Button and Indicator
Pushing this buttons allows you to send the signal from all AUX
Returns to solo mixing bus (which is, intern, sent to the Control
Room / Phones mixing bus). When the Solo is activated, the
corresponding LED indicator will illuminate.
48. AUX Send 1 to 4 Master Controls and Indicator
These controls adjust the nal level of the AUX 1, 2, 3 and 4 signals
(as taken from the AUX level controls 1 to 4 on each channel strip),
the audio of which is sent to the corresponding AUX sends. The
AUX 3 control not only adjusts the output level of the AUX 3/EFX
mix that is sent to the corresponding output, but also the signal
sent to the built-in Effect Processor as well. The Solo buttons allow
you to direct the AUX Send signals to the Control Room / Phones
mixing bus for monitoring purposes. When any of the AUX solo
buttons is activated, the AUX Solo LED will illuminate.
49. Control Room / Phones Control
This control is used to adjust the audio level of the Control
Room and Phones feeds, for use in the monitoring and tracking
of audio. The signal is then sent to the Control Room outputs
on the rear of the Helix Board 24 Universal mixer, as well as the
Phones jack on the face of the mixer.
50. Pre / Post Button and Solo Indicator
This button alternates the solo source signals between those
of post-fader and pre-fader feeds, to be sent to the Solo and
Control Room / Phones mixing bus. When the Solo indicator,
located beside the main level meter, is illuminated, it means
one or more Solo buttons has been pushed; therefore the Main
Level meter will display properties of the Solo signal, which
is helpful in the setting of channel properties. If Solo indicator
illuminates green, this means the Solo feed is a pre-fader signal;
if the solo indicator illuminates red, the feed is post-fader.

52. 2T Return Control and To Main Button
Turning the 2T Return level control adjusts the signal level of
the feed from the 2T Return inputs. The “ to Main” button that
accompanies this control allows users to send the 2T return
signal to the Main L-R mixing bus. When this is done, the Main
L-R mix signal is not sent to the Rec Out, as to avoid producing
a feedback loop when recorded signals are fed back into the 2T
return.

53. USB / FireWire Source and “Assign To” Buttons
Pushing the USB / FireWire button allows users to send the
signal received by the mixer through the USB / FireWire
interface to the Main L-R mix and/or AUX 1 mix, as selected by
the corresponding button.
54. FireWire Selector Switch
This sw i t c h determines which
of the Helix Board’s signals will
be use d for the 17th and 18th
channels sent through the FireWire
interface to the computer. Users
can c hoose to sen d the stereo
signal from the Main L/R, Group 1/2 or AUX 3/4 mix and utilize
the signal on their computer through their DAW software. This
additional stereo channel cannot be utilized through the USB
interface.
55. USB / FireWire Trim Control
This trim control can be used to adjust the level of the outgoing
FireWire signal for Channels 17 and 18 (which will be received
by the computer). If the input signal received by your computer
is noticeably exces sive, usin g thi s control could help to
attenuate the signal to an acceptable degree.
56. +48V Indicator
This indicator will illuminate when the master Phantom Power
switch is activated.
54
55
57. Power Indicator
The Power Indicator will light up when the power of the mixer is on.
58. Level Meter
This dual 12 segment level meter gives an accurate indication of
when audio reach certain levels. The 0 dB indicator illuminates
is approximately equal to an output level of +4 dBu (balanced),
and the PEAK indicator illuminates about 1.5 dB before the
signal is dynamically clipped. It is advised that users set the
various level controls so that the level sits steadily around 0 dB
to make full use of audio, while still maintaining fantastic clarity.
If any Solo buttons are activated on channels 1 through 16, or in
the master section, the Level Meter will display the Solo signal
’s properties. However, if no solo buttons are activated, the
Control Room / Phones selected sources (Main L-R, Group 1-2,
Group 3-4, 2T Return, Aux Return 4 and FireWire Return) signal
properties are displayed by the Level Meter. In this case, the
Level meter will display the sum of the selected signals.
59. Group 1 to 4 Controls
These four faders are the nal level control for the Group 1 to
4 audio feeds, sent to the corresponding Group outputs on the
rear of the Helix Board 24 FireWire to feed external devices
such as effect processors, and, quite commonly, multi-track
recorders. These faders can be fed a signal from the various
input channels (as well as the AUX Return 3) 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 individual left and right buttons
that allow users to send the various Group signals to the Main
Left and Right mix. This can be handy when wanting to combine
the signals from different input channels and control their input
levels simultaneously, then send them to the Main audio mix. A
good example of when this can be done is when multiple inputs
are used for drums; users can combine these inputs together to
be controlled much simpler by a single fader.
60. Main L/R Fader
This fader is the nal level control for the Main Left and Right
audio feeds, sent to the Main L and R outputs. When pushed
all the way up, the Main L/R fader provides 10 dB of gain to the
signal, and when set all the way down, the signal is effectively
muted.

FireWire and USB Pre / Post Switches
On the bottom of the Helix Board 24 Universal, users will nd
a small cover held in place by a screw. By removing this screw
and sliding the cover to the left, the pre/post switches for every
input channel are accessible. Flicking one of these switches to
the left will ensure the signal sent through the FireWire / USB
interface from that particular channel is affected by the channel’
s 3-band EQ, level fader and low-cut lter; to the right, the signal
will be unaffected by these controls. It is advised that users set
the pre/post settings for each input channel before plugging
the unit into an AC power source. Replace the cover and screw
before plugging the mixer back in and turning it on.

Cubase LE 4
Cubase LE 4 is a fairly powerful program provided along with
the Helix Board 24 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 Cubase included,
and users must upgrade or nd other suitable DAW software if
they choose to record more tracks.
Installation
Insert the Cubase LE 4 installation DVD that came with your
mixer into the DVD drive of your computer. Run the installer.
When rst running Cubase, you will be prompted with a request
for an activation code. Users must sign up to Steinberg’s
MySteinberg service to receive an activation code.
Setup
After successfully completing the installation process, the
following process must be followed to work efciently with the
Helix Board 24 Universal mixer.
1. Open the Cubase LE 4 program.
2. Go to the ‘Devices’ pull-down menu and select ‘Device
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.’
4.
Activate the audio tracks received from the Helix Board
mixer by following the following steps.
a. Go to the “devices” pull-down menu and select ‘VST
Inputs.’ This will display the various inputs (“HB 24 U Ch
1,” “HB 24 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 4. If more input
channels are needed, we suggest upgrading to a higher
version of Cubase, or using 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 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 Device connected to their computer.
Input Channels
If you wish to reset the Helix Board 24 Universal ASIO driver,
simply go to the ‘devices’ pull-down menu and select ‘device
setup’. Simply click “reset” and select the “Phonic ASIO Driver”.
Click ‘ok’ to continue.
The Input Channels section allows users to view and edit the
name of the various input channels received from the USB/
FireWire input. For a list of default channel names, please
consult the table on page 13.
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 24 Universal mixer.
Synchronization
In the Synchronization section, users can adjust the sampling
rate and other synchronization properties. Many of these
adjust able pro perti es, as t hey a re, are set for optimum
performance and, unless you are sure of what you need to
change, are probably best left alone.
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 24
Universal is the “master” clock source of the device. The other
options allow users to make the Helix Board 24 Universal follow
the “timing” of whichever device is the clock source. Having two
clock sources has the potential to cause undesireable results to
your audio, so it is best avoided. If the Helix Board 24 Universal
is the only piece of digital audio equipment attached to the
computer, there is no reason this option should be changed.
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 match the sampling rate.
Settings
The ASIO Buffer Depth is adjusta ble 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 either the USB or
FireWire connections have been interrupted can be viewed.
Streams
In the Streams section, the Helix Board 24 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.
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 24 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.
