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.
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.

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.
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 fill 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 final 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 flash 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.
