of these, users have the ability to monitor the 2T return, Group
1-2, Group 3-4, Main L-R and returned USB/FireWire signals,
either together or individually. There is also a "Control Room /
Phones only" button located beneath the Aux Return 4 control,
that, when pushed, sends the AUX Return 4 signal to the
Phones / Control Room mixing bus.

52. 2T Return Control and To Main Button
Turning the 2T Return level control adjusts the signal level of
the feed from the 2T Return inputs. The " to Main" button that
accompanies this control allows users to send the 2T return
signal to the Main L-R mixing bus. When this is done, the Main
L-R mix signal is not sent to the Rec Out, as to avoid producing
a feedback loop when recorded signals are fed back into the 2T
return.

53. USB / FireWire Source and "Assign To" Buttons
Pushing the USB / FireWire button allows users to send the
signal received by the mixer through the USB / FireWire
interface to the Main L-R mix and/or AUX 1 mix, as selected by
the corresponding button.
54. FireWire Selector Switch
This switch determines which
of the Helix Board's signals will
be used for the 17th and 18th
channels sent through the FireWire
interface to the computer. Users
can choose to send the stereo
signal from the Main L/R, Group 1/2 or AUX 3/4 mix and utilize
the signal on their computer through their DAW software. This
additional stereo channel cannot be utilized through the USB
interface.
55. USB / FireWire Trim Control
This trim control can be used to adjust the level of the outgoing
FireWire signal for Channels 17 and 18 (which will be received
by the computer). If the input signal received by your computer
is noticeably excessive, using this control could help to
attenuate the signal to an acceptable degree.
56. +48V Indicator
This indicator will illuminate when the master Phantom Power
switch is activated.

57. Power Indicator
The Power Indicator will light up when the power of the mixer is on.
58. Level Meter
This dual 12 segment level meter gives an accurate indication of
when audio 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 advised that users set the
various level controls so that the level sits steadily around 0 dB
to make full use of audio, while still maintaining fantastic clarity.
If any Solo buttons are activated on channels 1 through 16, or in
the master section, the Level Meter will display the Solo signal
's properties. However, if no solo buttons are activated, the
Control Room / Phones selected sources (Main L-R, Group 1-2,
Group 3-4, 2T Return, Aux Return 4 and FireWire Return) signal
properties are displayed by the Level Meter. In this case, the
Level meter will display the sum of the selected signals.
59. Group 1 to 4 Controls
These four faders are the final level control for the Group 1 to
4 audio feeds, sent to the corresponding Group outputs on the
rear of the Helix Board 24 FireWire to feed external devices
such as effect processors, and, quite commonly, multi-track
recorders. These faders can be fed a signal from the various
input channels (as well as the AUX Return 3) depending on your
selections. When pushed all the way up, these faders provide
10 dB of gain to the signal, and, when set all the way down,
effectively mute the signal.
The Group Controls also feature individual left and right buttons
that allow users to send the various Group signals to the Main
Left and Right mix. This can be handy when wanting to combine
the signals from different input channels and control their input
levels simultaneously, then send them to the Main audio mix. A
good example of when this can be done is when multiple inputs
are used for drums; users can combine these inputs together to
be controlled much simpler by a single fader.
60. Main L/R Fader
This fader is the final level control for the Main Left and Right
audio feeds, sent to the Main L and R outputs. When pushed
all the way up, the Main L/R fader provides 10 dB of gain to the
signal, and when set all the way down, the signal is effectively
muted.
