Quick Start

warning
  • The Hear Back OCTO Mixer is capable of driving most headphones to extreme levels that can damage your HEARING!
  • ALWAYS turn down the Mixer "Master Volume" down before putting on in-ear headsets or headphones.
  • It is the user's responsibility to prevent hearing damage by virtue of excessive headphone "Master Volume" settings.

Connecting the System​

  1. Connect the appropriate input(s) as shown in the hook-up diagram.
  2. Select the desired input using the front panel switch.
  3. Connect Hear Back OCTO Mixers to the Hear Back OCTO Hub Mixer Outputs using CAT6 or CAT5e cables.
  4. Set all Mixer Channels and Master Volume levels to "Off" (full counter-clock-wise position).
  5. Connect the headphones, in-ear monitors, and/or line outputs for connecting to wireless in-ear systems, powered monitors, or other devices requiring line-level inputs.
  6. Apply power to the Hub.

Hub Adjustment​

  1. Adjust the level at the input source (DAW, Mixer, etc.) until the clip LED's on the Hub just come on and then reduce the input(s) until you have a bright blue LED.
  2. Adjust the source for as much signal into the Hub as possible without clipping. Higher input levels improve signal-to-noise and dynamic range.

Mixer Adjustment​

  1. After you have the signals optimized on the Hub, turn the "Master" Volume up to about 10 o'clock.
  2. Raise each channel's volume to a comfortable level.
  3. Avoid adjusting the master volume too high and running the inputs too low.
note

The HearBus and Mixer outputs contain high speed digital audio and should be treated as a transmission line. DO NOT "Y" these connections because the terminated controlled impedance will be comprised. The HearBus and Mixer outputs operate at 12.28 MHz.

Now enjoy personal monitoring at its best and have fun!
