HELIX BOARD 12 PLUS
INSTANT SETUP
Getting Started
1.
Ensure all power is turned off on your mixer. To totally
ensure this, the power adapter should not be connected
to the unit.
2.
All faders and level controls should be set at the lowest level
and all channels muted to ensure no sound is inadvertently
sent through the outputs when the device is switched on.
All levels can be altered to acceptable degrees after the
device is turned on using the channel setup instructions.
3.
Plug any necessary equipment into the device’s various
inputs and outputs. This could include amplifiers and
speakers, monitors, signal processors, recording devices,
guitars, keyboards, microphones, and so on.
4.
Plug the supplied power adapter into the power inlet on the
back of the device and then into a power outlet of a suitable
voltage.
5.
Turn the power switch on and follow the channel setup
instructions to get the most out of your equipment.
Channel Setup
1.
To ensure the correct audio level of the input channel is
selected, each of the level input controls of the Mixer should
be turned counter-clockwise or down as far as they will go
and the mute buttons should all be engaged.
2.
No input other than the one being set should have any
device plugged in. This will ensure the purest signal is used
when setting channels.
3.
Adjust the LEVEL and AUX 1 volume controls of the channel
you are setting to around the 2 o’clock mark. Also set the
Main L-R fader to the 0 dB mark.
4.
Press the AUX 1 button on the Control Room Source section
down (making sure all others are released), allowing the
level meter to display the level of the channel being set.
5.
Ensure the channel has a signal sent to it similar to the
signal that will be sent when in common use. For example,
if the channel is using a microphone, then you should speak
or sing at the same level the performer normally would
during a performance; if a guitar is plugged into the channel,
then the guitar should also be strummed as it normally
would be (and so on). This ensures levels are completely
accurate and avoids having to reset them later.
6.
Set the channel’s gain so that the Level Meter indicates
the audio level is around 0 dB, ensuring the level never
r5 dB.
7.
This channel is now ready to be used; you can stop making
the audio signal.
8.
You can now select another channel and repeat the same
process.
