HELIX BOARD 12 UNIVERSAL
INTRODUCTION
Thank you purchasing the Helix Board 12 Universal, one of Phonic’s newest mixers that sounds great and works hard both in and out of the studio. The mixer features USB 2.0 and FireWire 400 interfaces that can stream up to 10 independent channels of audio to the computer and return two tracks for monitoring, all at screaming fast transfer rates of up to 24-bit/96 kHz. An onboard 40-bit digital multi-effect processor provides 100 popular programs plus tap delay, test-tones and foot switch jacks.
There are 4 extremely low noise Mic preamps, each with phantom power, spread across four mono channels and two stereo channels, each featuring a 3-band EQ. Additional features include two AUX sends, two stereo AUX returns, an extra ALT 3-4 stereo mixing bus, Steinberg Cubase LE 4 digital audio workstation software and an optional 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
applications of your brand new mixer. If you do happen to be one
of the many people who atly refuse to read user manuals, then
we just urge you to at least glance at the Instant Setup section. After glancing at or reading through the manual (we applaud you if you do read the manual in its entirety), 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.

1 x Helix Board 12 Universal mixer 1 x USB cable 1 x FireWire cable 1 x DVD with drivers & Steinberg Cubase LE 4 1 x Power supply and cable Optional: ER-12MUX rack mounting kit If any items are missing from your package, please contact your
nearest Phonic dealer.
INSTANT SETUP
Getting Started
1. Ensure all power is turned off on your mixer. To totally ensure
this, the power adapter should not be connected to the unit.
2.
All faders and level controls should be set at the lowest level and all channels muted 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 inputs
and outputs. This could include ampliers and speakers,
monitors, signal processors, recording devices, guitars, keyboards, microphones, and so on.
4.
Plug the supplied power adapter into the power 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 level input controls of the Mixer should be turned counter-clockwise or down as far as they will go and the mute buttons should all be engaged.
2. No input other than the one being set should have any device
plugged in. This will ensure the purest signal is used when setting channels.
3. Adjust the LEVEL and AUX 1 volume controls of the channel
you are setting to around the 2 o’clock mark. Also set the Main L-R fader to the 0 dB mark.
4. Press the AUX 1 button on the Control Room Source section
down (making sure all others are released), allowing the level meter to display the level of the channel being set.
5. Ensure the channel has a signal sent to it similar to the signal
that will be sent when in common use. For example, if the channel is using a microphone, 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.
6. Set the channel’s gain so that the Level Meter indicates the
audio level is around 0 dB, ensuring the level never reaches +5 dB.
7. This channel is now ready to be used; you can stop making
the audio signal.
8. You can now select another channel and repeat the same
process.
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 preampliers, serving for crystal
clear sound replication. The Helix Board 12 Universal mixers feature a total of four standard XLR microphone inputs.
NB. When these inputs are used with condenser microphones, the Phan­tom Power should be activated. However, when Phantom Power button 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 or TS inputs, for balanced or unbalanced signals. They can be used in conjunction with various line level devices, such as keyboards, drum machines, electric guitars, and a variety of other electric instruments.
3. Stereo Channels
The Helix Board 12 Universal mixer features a couple of stereo
channels, thrown in for maximum exibility. Each of these stereo
channels features two 1/4” TRS phone jacks, for the addition of various line level input devices, such as electronic keyboards, guitars and external signal processors or mixers. These Stereo Channels can also be used as Mono channels, where the signal from any 1/4” phone jack plugged into the Left stereo input will be duplicated to the Right input due to the miracle of jack normalizing (this does not work in reverse, however).
4. Stereo AUX Return
These 1/4” TS inputs are for the return of audio to the Helix Board 12 Universal mixer, processed by an external signal processor. If really needed, they can also be used as additional stereo inputs, with a level control located on the face of the mixer. The Stereo AUX Return can also accept Mono signals, where plugging the 1/4” phone jack of any device into the Left input will cause the signal to be duplicated to the Right input also (this does not work in reverse, however). Signals processed by the built-in digital effects processor are cut-off when any 1/4” phone jack is plugged into the AUX return 2.
5. AUX / Effects Send
These 1/4” TS outputs may be used to connect to an external
digital effect processor, or even to an amplier and speakers
(depending on your desired settings), to the mixer. The AUX send is a pre-fader signal, suitable for sending to monitors to allow performers to monitor their music. The EFX send signal is post-fader, suitable for sending to external effect processors, and then return back to the AUX returns.
6. Main L and R Outputs
These two ports will output the nal stereo balanced 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 ampliers (and in-turn, a pair of speakers),
other mixers, as well as a wide range of other possible signal processors (equalizers, crossovers, etcetera).

8. 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 / Submix rotary control.
9. Record Out
These outputs will accommodate RCA cables, able to be fed to a variety of recording devices.
10. 2T Return
This stereo RCA input is used to connect the mixer with external devices, such as tape and CD players, and feeds the signal to the Main L-R mixing bus.

Rear Panel
11. Channel Inserts
Located on the rear of the Helix Board, 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 and 2. This will require a Y cord that can send (pre-fader and pre-EQ) and receive signals to and from an external processor. On this connection, the tip pin is for sending the signal, whereas the ring pin is for return. The sleeve pin, on the other hand, is the ground.
12. ALT 3-4 Output
The signal sent from these 1/4” outputs is fed from the ALT 3-4 mixing bus, and can be used in conjunction with a large array of devices, including signal processors, other PA systems, recording devices, and so on.
13. Foot Switch Jacks
These ports are for the inclusion of a foot switch, used to remotely adjust properties of the built-in Digital Effect processor, to the mixer. The left jack is used to adjust the tap delay properties, whereas the right jack is used for turning the effects on and off.
13 12 11
7. Control Room Outputs
These two 1/4” Phone Jack outputs feed the signal altered by the Control Room / Submix 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, enabling, for instance, the monitoring of the audio signal from within a booth.

Channel Controls
20. Low Cut Filter (75 Hz)
This button, located on channels 1 through to 4, will activate a
low-cut / 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.
21. Mic / Line Gain Control
This controls the sensitivity of the input signal of the Microphone / Line 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, based on the channel setup instructions. This can be accomplished by adjusting it to a level that will allow the peak indicator occasionally illuminate. All 4 mono channels feature this control.
14. USB 2.0 Connection
This USB 2.0 port is for connecting the Helix Board to any PC or Macintosh computer. It allows all 8 input channels to be streamed to a computer, as well as an additional stereo channel. A stereo audio channel from the computer can also be returned to the Helix Board for monitoring. The audio sent to the computer can be either pre- or post-fader, depending on the pre/post setting on each input channel. The main left and right signal, AUX signal and ALT 3/4 (all of which can also be sent through the USB interface) are pre-fader signals. The returned USB signal can be utilized in the USB Return section on the face of the mixer.
15. FireWire Connections
These two FireWire ports, just like the USB connection, are for connecting the Helix Board to any PC or Macintosh computer. The exact same channels sent to and from the computer through the USB port can be utilized through this connection. Please note that the FireWire and USB connections cannot be used simultaneously.
16. Power Connector
This port is for the addition of a power cable and supply, allowing power to be supplied to the mixer. Please use the external power supply that is included with this mixer only as using other adaptors could damage the mixer. For a replacement supply, contact your nearest Phonic dealer.
CONTROLS AND SETTINGS
Rear Panel
17. Power Switch
This switch is used to turn the mixer on and off. Ensure you turn all level controls down before activating.
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. FireWire / USB Switch
When connecting the unit to the computer through a FireWire cable, this switch should be set to the left. When connecting to
the computer through USB, it should then be set to the right.
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 (2.5 kHz) sounds at a range of ±15 dB. Changing middle frequencies of an audio feed can be
rather difcult when used in a professional audio mix, as it is
often more desirable to cut middle frequency sounds rather than boost them, thereby soothing overly harsh vocal and instrument sounds in the audio.
24. 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.
25. Pre/Post Switch
This switch is used to change the signal of the corresponding channel that is sent to the Computer via the USB or FireWire interface between that of a pre-EQ, pre-fader, pre-low cut to that of a post-EQ, post-fader, post-low cut. In the uppermost position, the channel will be pre, and in the lower position post.
26. AUX 1 (Monitor) Control
This control allows the user to send the corresponding signal to the AUX 1 output, which can be used in conjunction with an
amplier and studio or stage monitors, or simply as an auxiliary
output for any means required. The control is pre-fader, therefore any changes made to the corresponding channel level control do not affect the AUX 1 send signal.
27. AUX 2 (Effects) Control
This control alters the signal level that is sent to the AUX 2 (or EFX) send output, which can be used in conjunction with external signal processors (this signal of which can be returned to mixer via the AUX return input, or any stereo input channel), or simply as an auxiliary output for any means required. This control is set to ‘post-fader,’ therefore any changes made to the corresponding channel level control are also applied to the EFX signal. The EFX send signal is also sent to the built-in effect processor for providing effects to the main output and AUX 1 send, as required.
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, this 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. Mute / ALT 3-4
This handy little button is basically a typical mute button – effectively stopping any signal received by the channel from being sent to the Main L/R or AUX 2 send mixing buses – however it does so much more. Pushing this button routes the channel’s signal away from the Main L/R and to its own “Alternate” stereo output (Alt 3-4), where the signal can be used at will. If you wish
to use it to connect an amplier and speakers, or simply patch it
through to an unused input channel, you can easily do so.
30. Peak Indicator
This LED indicator will illuminate when the device hits high peaks, 6 dB before overload occurs. It is best to adjust the gain of the channel so that the PEAK indicator lights up on intervals only. This will ensure a greater dynamic range of audio. This LED will light up while the Mute button is pushed in.
31. Level Control
This rotary control will alter the signal level that is sent from the corresponding channel to the Main or Alt. 3-4 mixing bus.
32. +4 / -10 Switch
This button, located on both stereo input channels, is used adjust the input sensitivity of the corresponding channels, which will adapt the mixer to external devices which may use different operating levels. If the input source is ­10 dBV (consumer audio level), it is best to engage the switch, allowing the signal to be heard. The +4 dBu level is suitable for Professional Audio signals, which are considerably higher than the consumer level. However, 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 the input signal is obviously too low).
32
Digital Effect Section
33. 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. 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.
34. 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 2/EFX control on one or all input channels to ensure the signal level is not excessive.
35. 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. Pushing this control will apply the new 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 will ash within the
digital effect display window at the selected intervals.
Master Section
36. AUX Stereo Return Controls
These controls adjust the signal level of audio fed through to the AUX Stereo Return inputs, which will be added to the MAIN L-R mix. The AUX Return 2 control also acts as a level control for the EFX processor when no device is plugged into the AUX 2 Return inputs.
37. EFX to Monitor Button
This button allows users to select the destination of the AUX Return 2 signal. Pushing it in sends the signal to the AUX Send 1 mixing bus.
Hint: Use this button to send your EFX signal to the AUX 1 mix. You can then send your AUX 1 and 2 mix to the computer as your additional stereo
mix. This will allow you to record your EFX!
38. AUX Send 1 Master Control
This control will adjust the nal output level for the AUX send
output, the signal of which is taken from the AUX 1 controls on each input channel.

42. Assign to Main Button
When the “Assign to Main” button is engaged, the USB/FireWire & 2T Return and Alternative 3-4 signals can be selected by using the corresponding buttons, and are, intern, sent to the Main L-R and Control Room mixing buses via the Control Room / Submix control. This can come in handy when you want play a CD during intermission in a live show, as this allows users to send the signals from the USB/FireWire interface, 2T RTN and/or ALT 3-4 to the main left and right outputs. If you have the Main L-R or AUX 1 buttons on the Control Room Source section engaged, the corresponding signals will not be sent to the control room and headphones output by the use of this button.

39. Source Select
This switch determines which of the Helix Board’s signals will be used for the 9th and 10th channels sent through the USB or FireWire interface to the computer. Users can choose to send the stereo signal from AUX 1/2, ALT 3/4 or the Main mix through the USB/FireWire interface.
40. Trim Control and Indicator
This trim control can be used to adjust the level of the outgoing USB and FireWire signal from channel 9/10 (which will be received by the computer). If the input signals received by your computer are noticeably excessive, using this control could help to attenuate the signal to an acceptable degree. The accompanying LED will illuminate when a connection is established through the FireWire interface.
43
43 Control Room / Submix Control
This control is used to adjust the audio level of the Control Room feed, which is sent to both the Control Room outputs (for
monitoring, acting as side ll or other purposes) and Phones
outputs (to be used in conjunction with headphones for monitoring purposes). It also acts as the “Submix” control, which allows the user to adjust the level of the signals selected by the Control Room Source when the Assign to Main button is engaged.
44. Main Level Fader
This 60mm fader is nal level control for the main left and right
audio feed, sent to the Main L and R output.
45. Level Meter
The stereo 8-segment level meter gives an accurate indication of when audio levels of the selected Control Room source(s) reach certain levels. It is suggested for the maximum use of audio to
set the various levels controls so that the Peak LEDs ash only
occasionally (and perhaps it is better if you ensure the level stays around a pinch below that).
46. +48 Indicator
The +48 Indicator illuminates whenever the Phantom Power switch is activated.
47. Power Indicator
The Power Indicator will light up when the power of the mixer is on.
41. Control Room Buttons
Engaging any of these four buttons will enable you to use the signal from any of the corresponding sources to send to the Control Room mixing bus and the LED Level Meter for level monitoring. For instance, pressing USB/FireWire & 2T Rtn button will allow you to send the 2 Track Return signal and the signal received through the USB/FireWire interface to the Control Room Outputs (the level of which will be visible on the Level Meter), where as the Main L-R will allow you to use the Main Left/Right signal, the AUX 1 allows you to use the AUX 1 signal, and the ALT 3-4 allows you to use the “Alternate” stereo mix bus signal. You can even use a combination of all these signals, if need be.

CHANNEL ASSIGNMENT
When using a Digital Audio Workstation on a PC, and within the included Phonic Helix Board 12 Universal control panel software, the following names have been attributed to the input channels of the mixer. They can be altered through the control panel software included with the mixer.
Computer Input Channel Name Mixer Channel HB 12U CH 1 Channel 1 HB 12U CH 2 Channel 2 HB 12U CH 3 Channel 3 HB 12U CH 4 Channel 4 HB 12U CH 5 Channel 5 (Stereo L) HB 12U CH 6 Channel 6 (Stereo R) HB 12U CH 7 Channel 7 (Stereo L) HB 12U CH 8 Channel 8 (Stereo R) HB 12U Main L user denable HB 12U Main R user denable
To alter an input channel’s name on your computer, open the Helix Board 12 Universal control panel software. On the left hand
side of the control panel, users will nd the settings categories.
By clicking “Input Channels”, the main window will display the titles input channels. You can then highlight the channel names and press the “Edit Channel Name” button on the bottom of the control window. A new window will appear that will allow users to adjust the channel name.
If you would like to use the Helix Board 12 Universal as your default audio output device on you PC, simply go into the Windows control panel, and select “Sound and Audio Devices”. Select the Audio tab, and use the pull-down menu to select the Helix Board 12 Universal from the list of available output devices. The Helix Board 12 Universal can also be selected as the default output device for individual programs by editing said programs’ settings / options.
a.
Go to the “devices” pull-down menu and select ‘VST
Inputs’. This will display the various inputs (“HB 12 U Ch 1”, “HB 12 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.
If you wish to reset the Helix Board 12 Universal ASIO driver for any reason, simply go to the ‘devices’ pull-down menu and select ‘device setup’. Click “reset” and select the “Phonic ASIO Driver.” Click ‘ok’ to continue and the connection to the Helix Board 12 Universal should reset.
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.
CUBASE LE 4
Cubase LE 4 is a fairly powerful digital audio workstation program provided along with the Helix Board 12 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 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 efciently with the
Helix Board 12 Universal mixer.
1.
Open the Cubase LE 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’. This completes the basic installation and setup.
4.

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 12 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. 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 12 Universal is the “master” clock source of the device. The other options allow users to make the Helix Board 12 Universal follow the “timing” of whichever device is the clock source. Having two clock sources has the potential to create very undesirable audio, so it should be avoided. If the Helix Board 12 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.
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 12 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.
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.
Streams
In the Streams section, the Helix Board 12 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.
