SE7261A Connectors and Controls

The SE7261A subwoofer supports digital audio only.
Illustrated below is the connector panel of the SE7261A subwoofer. In the bottom left corner are the
AES/EBU digital audio inputs and outputs. The subwoofer has four AES/EBU inputs and four AES/EBU
outputs.
The SE7261A can perform bass management. The DSP bass management system splits the signal
from each input into low and high frequency components. Signal content below the crossover frequency
is reproduced by the subwoofer and signal content above the crossover frequency is reproduced by the
loudspeakers connected to the outputs of the subwoofer. Frequencies above the cross-over frequency
from input 1 are directed to output 1, frequencies above the cross-over frequency from input 2 are directed
to output 2 and so on. In a practical example, a cable carrying Left and Right signals is connected first
to INPUT number 1 on the subwoofer and then the OUTPUT number 1 is connected to Left and Right
loudspeakers. For bass management to work, the subwoofer must be first in the audio chain but after that
the loudspeakers can be connected in any order.
All digital audio inputs and outputs are referenced to 0 dBFS (digital Full Scale, the largest possible signal
that can be represented by an AES/EBU signal). Genelec GLM.SE™ system loudspeakers produce a
sound pressure level of 100 dB SPL (at one meter distance in free space) for a digital input signal of –15
dBFS.
