INTRODUCTION Thank you for choosing one of Phonic’s many quality products. The Helix Board 17 Compact Mixers with USB interface – designed by the ingenious engineers that have created a variety of mixers fantastic in style and performance in the past – display similar proficiency that previous Phonic products have shown; with more than a few refinements, of course.
GETTING STARTED Basic Setup Channel Setup 1. Ensure all power is turned off on your mixer. To totally ensure this, the AC cable should not be connected to the unit. 1. 2. All faders and level controls should be set at the lowest level and all channels switched off 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.
Making Connections Inputs and Outputs 1. XLR Microphone Jacks These jacks accept typical 3-pin XLR inputs for balanced and unbalanced signals. They can be used in conjunction with microphones – such as professional condenser, dynamic or ribbon microphones – with standard XLR male connectors, and feature low noise preamplifiers, serving for crystal clear sound replication. The Helix Board 17 mixer features five standard XLR microphone inputs. NB.
Rear Panel 11. Channel Inserts Located on the rear of the Helix Board 17, 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 5. This will require a Y cord that can send (pre-fader and pre-EQ) and receive signals to and from an external processor.
Channel Controls 20. Low Cult Filter (75 Hz) This button will activate a high-pass filter that reduces all frequencies below 75 Hz at 18 dB per Octave, helping to remove any unwanted ground noise or stage rumble. 21. Gain Control This controls the sensitivity of the input signal of the Line/ Microphone input. The gain should be adjusted to a level that allows the maximum use of the audio, while still maintaining the quality of the feed.
33. +4 / -10 Buttons These buttons, located on each stereo input channel, are used adjust the input sensitivity of the corresponding channel, which will adapt the mixer to external devices which may use different operating levels. If the input source is -10 dBV (consumer audio standard), it is best to engage the switch, allowing the signal to be heard.
43. Return Solo Button 49. +48V Indicator Pushing this buttons allows you to send the signal from the 3 AUX Returns to the Control Room / Phones mixing bus. This indicator will illuminate when Phantom Power is activated. 44. AUX Send Master Control 50. Power Indicator This rotary 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.
USB INTERFACE By simply connecting the USB cable provided along with your Helix Board 17 to the device and your Personal Computer or Laptop, you are able to send CD quality (16-bit stereo, with a 44.1 kHz sampling rate) signal to and from your Helix Board 17. By doing this, you are actually turning your Helix Board 17 into a highly useful plug'n'play soundcard for your computer.
Application On the following couple of pages you will find a wide range of possible uses for the Helix Board 17 mixers. Of course these are far from the only applications that can be attributed to the mixers’ use; however they should give you an idea of the possible uses that the various inputs and outputs have.
