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, test-
tones and foot switch jacks. The multi-directional Input/Output
pod makes the device versatile; making rack mounting or table-
top 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
find 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 find, because chances are there's something you missed the
first 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. This could include amplifiers and speakers,
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 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.
