9. Main Outputs
stereo line level signal sent from the main mixing bus. The
primary purpose of these jacks is to send the main output
(and in-turn, a pair of speakers), other mixers, as well
as a wide range of other possible signal processors
(Equalizers, Crossovers, etcetera).
10. Group Outputs
feed from the Group 1 and 2 mix controlled by the Group
level faders. These outputs can be used to feed a wide
range of devices, such as mixers, signal processors, and
along with the Main Speakers, for a more rounded audio
experience.

11. Channel Inserts
Located on the rear of the Helix Board 18 Universal, 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 Universal, 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
supplying audio to indoor areas that the main speakers do
not reach. When using the FireWire or USB 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.

14. Main XLR Outputs
signal sent from the main mixing bus. The primary purpose
of these jacks is to send the main output to external
turn, a pair of speakers), other mixers, as well as a wide
range of other possible signal processors (equalizers,
crossovers, etcetera).
