Page: 11 / 21

8. 70V WIRING SETUP
• Use 1 separate wire run for:
Subwoofer portions of Bollards
• Use another separate wire run for:
Satellite portions of Bollards
The Beoamp 125.4 (BEO125 amplifier) from B&O | Origin Acoustics was specifically designed
to drive the Beosound outdoor speaker systems. In 70V, is the recommended amp for Sub
control and DSP for best performance.
The BEO125 amplifier offers EQ and crossover presets specifically for the Beosound Bollards.
These presets have active crossovers that remove the bass from the satellites and send that
bass only to the subwoofers. This more effectively controls how the subwoofer interfaces
with the satellites and permits you to control the subwoofer-to-satellite balance. The digital
signal processing or “DSP” also shapes the sound for both subs and satellites to create
optimum performance.
8A. 70V INSTALLATION NOTES
• The subwoofers and satellites will be run in PARALLEL.
This means the positive connection on the amplifier will be connected to the positive
connection on speaker 1, 2, 3, etc. The negative connection will be connected to the negative
connections on the speakers as well. This can be accomplished with a single pair of wires in a
“daisy chain” where the amplifier is at one end and the speakers are connected consecutively.
• If desired, you can also wire in a star pattern where each speaker is directly wired back to
the amplifier.
