A. Adjust the level at the input source (DAW, mixer, etc.)
until the red clip LED’s on the Hub just come on.
B. Reduce the levels on the input source until you have
a “green” LED.
C. Adjust the source for as much signal into the Hub as
possible without clipping. Higher input levels improve
signal-to-noise and dynamic range. If you are unable to
adjust your source without overdriving the Hear Back
PRO system, follow the “-10dB Pad” instructions below to
achieve and extra 10db of headroom. Remember, higher
input levels improve signal-to-noise and dynamic range.

C. Avoid adjusting the master volume too high and running
the inputs too low.
D. To stereo-link any channels, enter the stereo-link control
interface as described in the User Guide, and toggle them on.

-10dB PAD: The Analog input card provides 2 jumpers per channel
(16 total) that can be removed to achieve a -10dB pad per channel.
These jumpers are labeled 1-8 (corresponding to each input
channel), and located one inch away from the DB-25 connector.
So, in this example, input channels 1 & 4 will be reduced by 10dB,
while input channels 2 & 3 are at 0dB:
