45. FireWire Assign Buttons
These three buttons allow users to select the
destination of the audio signal received through the
FireWire interface. They are pretty straight forward,
the “To Ctrl Rm” button allows the signal to be sent
to the Control Room mixing bus, the “Assign to Main”
button allows users to send the signal to the Main L-R
mixing bus, and the “Assign to AUX 1” button allows
users to send the signal to the AUX 1 mixing bus. It
couldn’t be simpler!
46. 2T Return Controls
Turning the 2T Return level control adjusts the signal
level of the feed from the 2T Return inputs. Pushing
either one of the buttons in the 2T Return Control
Section selects the destination of the 2T Return signal.
The uppermost button (“to Ctrl Rm”) sends the signal
to the Control Room/Phones mixing bus, whereas the
lower button (“to L/R”) sends the signal to the Main L-
R mixing bus. These buttons can, of course, be used
simultaneously, feeding the signal to both the Control
Room/Phones and Main L/R mixing bus. Please note,
that when the "to L/R" button is pressed, there is no
signal from the record output.
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 13 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
about 1.5 dB before the signal
is dynamically clipped. It is
suggested for the maximum use
of audio to set the various levels controls so that it 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,

41. AUX Send Master Control
This control adjusts the final level of the
AUX mixing bus (as taken from the AUX
level controls on each channel strip), the
audio of which is sent to AUX Send 1
output. The corresponding SOLO button
allows you to send the AUX Send signal
to the Control Room / Phones mixing bus.
The Helix Board 18 FireWire has 2 AUX
sends, where the first is in fact a 60mm
fader, rather than the typical rotary control.
Also incorporated with the AUX 1 control is
an ON button and indicator, allowing AUX
1 to be activated and muted by the push of
a button. Activation of the AUX 1 channel is
accompanied by an illuminated LED.
42. EFX Send Master Control
This control adjusts the final level of the
EFX mixing bus (as taken from the EFX
level controls on each channel strip), the
audio of which is sent to the AUX Send
3 outputs, as well as the built-in digital
effect engine. The corresponding SOLO button allows
you to send the signal to the Control Room / Phones
mixing bus.
43. Control Room / Phones Controls
This control is used to adjust the audio level of the
Phones feed, as well as the signal sent to the Control
Room output, for use in monitoring and tracking of
audio. Below is a table showing the priority of the
signals received by the Control Room / Phones mixing
bus. If the first priority signal is not available, the
second priority signal will be used, and so forth.
