Helix Board 18 FireWire MKII
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 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.
3. 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.
4. Plug any necessary equipment into the device’s
YDULRXVRXWSXWV7KLVFRXOGLQFOXGHDPSOL¿HUVDQG
speakers, monitors, signal processors, and/or
recording devices.
5. Plug the supplied AC cable into the AC inlet on the
back of the device and a power outlet of a suitable
voltage.
6. Turn the power switch on.
7. Consult the FireWire section of this manual for
more information on its setup and usage.
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 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.

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.
4. AUX Returns
These 1/4” TS inputs are for the return of audio to the
Helix Board 18 FireWire MKII 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.
5. AUX Sends
These 1/4” TRS outputs may be used to connect to an
H[WHUQDOVLJQDOSURFHVVRURUHYHQWRDQDPSOL¿HUDQG
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 FireWire
MKII features a total of 3 AUX Sends. When using
the FireWire 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.

speakers to be used along with the Main Speakers,
for a more rounded audio experience.
Rear Panel
11. Channel Inserts
Located on the rear of the Helix Board 18 FireWire
MKII, 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
FireWire MKII, and the Sleeve is the grounding.
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
ZHOODVDFWLQJDVD³VLGH¿OO´RXWSXWVXSSO\LQJDXGLR
to indoor areas that the main speakers do not reach.
When using the FireWire 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 built-
in 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.

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 connection is made. If the
FireWire output is connected to a computer, than the
S/PDIF output sampling rate will be the same as that
set by the Helix Board Control Panel software.
16. FireWire Connections
The two FireWire connectors are for linking the
Helix Board 18 FireWire MKII 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
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 FireWire MKII 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)

ORZFXW¿OWHUDIIHFWVRQO\WKH;/50LFURSKRQHLQSXWV
(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
IUHTXHQFLHV RI DQ DXGLR IHHG FDQ EH UDWKHU GLI¿FXOW
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
FireWire MKII 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.
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).
25. FireWire Pre/Post Switch
This switch is used to change the signal of the
corresponding channel that is sent to the Computer
via the FireWire 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.

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
SURJUDP D VPDOO /(' ZLOO ÀDVK XQWLO \RX SXVK WKH
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

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.”

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 Trim Control
This is one of the newest features of the Helix Board
18 FireWire MKII. The FireWire trim control can be
used to adjust the level of the outgoing FireWire signal
(which will be received by the computer) from the AUX
2/3, Group 1/2 or Main L/R (depending on the FireWire
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.
44. FireWire Select Switch
This switch determines which of the Helix Board’s
signals will be used for the FireWire channels 15 and
16 sent through the FireWire interface to the computer.
Users can choose to send the two channel signal from
the Auxiliary 2/3, Group 1/2 or Main mixes (all pre-
level controls) to the computer.
45. FireWire “Assign to” Buttons
The Assign to Main and Assign to AUX 1 buttons
allow users to determine the destination of the stereo
FireWire return signal.
46. FireWire Indicator
This blue LED indicator will illuminate when a
connection is established through the FireWire
interface.
47. +48V Indicator
This indicator will illuminate when Phantom Power is
activated.
48. Power Indicator
The Power Indicator will light up when the power of
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.
When the Solo indicator, located beside the Level
Meter, is illuminated, one or more Solo buttons has
been pushed. In that case, the Level meter will
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 pre-
fader 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, Group
1-2, 2T Return and Main mixes. These signals can be
monitored simultaneously if required.
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).

received through the RCA 2T Return inputs. The To
Main button allows users to send the 2T Return signal
to the main mix.
54. AUX Return 1 and 2 Faders
This 60mm fader adjusts the signal level of audio fed
through the stereo AUX Return input. This AUX Return
features L/R, GP 1/2 assign buttons, enabling users
to send the audio feed to the corresponding mixing
buses. Also, features a Solo button that sends the
signal directly to the Control Room / Phones mix. The
On button allows you to turn the AUX Return channel
on and off. Activation of the AUX Return or AUX Return
Solo will be accompanied by an illuminated LED.
55. AUX Return 2 to AUX 1 Control
This rotary control allows users to adjust the level of
audio that is sent from the AUX Return 2 signal to the
AUX Send 1 mix.
56. Group 1/2 Controls

Helix Board Control Panel
The Helix Board FireWire control panel can be ac-
cessed 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 la-
tency 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 FireWire Devices connected
to their computer.
Input Channels
The Input Channels section allows users to view and
edit the name of the various input channels received
from the FireWire input. For a list of default channel
names, please consult the table on page 16.
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 FireWire MKII
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.
First off, the synch mode can be altered, though mak-
ing this alteration is not recommended for novice users.
The synch mode is basically the way the computer de-
termines 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 FireWire
MKII is the “master” clock source of the device. The
other options allow users to make the Helix Board 18
FireWire MKII follow the “timing” of whichever device
is the clock source. Having two clock sources has
the potential to create very undesireable audio, so it
is best avoided. If the Helix Board 18 FireWire MKII
is the only piece of digital audio equipment attached
to the computer, there is no reason this option should
be changed.

19
Helix Board 18 FireWire MKII
Users are also able to change between automatic
and manual sampling rate settings. When the sam-
pling 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 us-
ing 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 FireWire
MKII. 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 op-
timal performance. The default settings are ideal for
most computers.
The ASIO Buffer Depth is adjustable between 4 and
40 milliseconds. This allows users to adjust the la-
tency 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
connection has been interrupted can be viewed.
Streams
In the Streams section, the Helix Board 18 FireWire
MKII device properties can be viewed. Each input
and output stream can be scrutinized, and the iso-
chronous stream number and its supported sampling
rates can be viewed.
