Safety should be the
fi
rst and foremost consideration when using this system.
For stability, the BRS-12A3/BRS-12-2 should not be used on a surface with more than +/- 5° incline if satellite
speakers are being pole mounted using the threaded insert adaptor.
If the unit has been stored in a cold environment, it should be allowed to come to room temperature before
use. If condensation forms on the rear panel, ensure the unit has dried before powering the system.
Do not use this unit without an earth connection. Ensure that any input source is connected to the same
mains circuit & earth point as the BRS-12A3 to avoid mains earth hum-loops.
Cables to and from the unit should be placed in a way that does not present a trip hazard. Ensure all cabling
is free from damage and that all connectors are properly seated before powering the system. Do not site the
system close to heat sources and ensure that there is suf
fi
cient air
fl
ow to prevent overheating.
Under no circumstances should this system be used in environments with high humidity or rain. If possible,
try to site the ampli
fi
er panel out of direct sunlight to reduce thermal loading and increase LCD visibility.
Only use genuine OHM accessories with this product
In simple system set-ups, the unit can be controlled entirely via the touch-screen display. After initial power-up, the
main screen on the LCD displays the Channel Meters screen. This shows VU input and output gains, gain reduction
levels and peak/RMS limit status.
The touchscreen menus operate with swipes from the left of the screen to the
right to progress through the different pages. A
fi
nger tip dragged gently across
the bottom section of the screen works best to change screens.
Swiping scrolls through the six screens as follows:
Channel Meters >>
Gain >>
Mute & phase >>
Channel delay >>
Channel Gain >>
Preset >>
