12. Main Outputs
These outputs will output the final 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 amplifiers (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,

open the holder cover, and replace the fuse with a suitable
replacement (as indicated underneath the power connector).

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.

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 the
ON position will activate +48V of phantom power for the
corresponding 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
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.
23. Mono Output Source Select Switch and Volume Control
The rotary control to the right adjusts the final 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.
