Two-Way Loudspeaker Functional Blocks
All audio enters audio input stage where all crossover and filtering takes place. The audio outputs go
via digital-to-analog conversion to built-in power amplifiers and on to the tweeter and woofer drivers.
The loudspeakers have built-in user interfaces with switches and a rotary level control on the front of the
loudspeaker.
Subwoofer (SE7261A)
Digital Audio Input
The digital input has a fixed sensitivity. Digital signals are represented relative to their maximum or Full
Scale value. For example, -10 dBFS means that the signal level is 10 dB below the full scale or the
maximum representable digital signal.
In Genelec SE7261A subwoofers, the maximum audio level of 0 dBFS translates to the theoretical 115 dB
SPL at 1 m sound pressure level. For example, a -36 dBFS signal produces a sound level of 79 dB SPL at
1 m. Genelec Loudspeaker Manager GLM.SE™ adjusts the monitoring volume down from this level.
Digital audio sample rates can vary from 32 kHz to 192 kHz and word length from 16 to 24 bits. Single-
Wire formats are only supported. Note that there may be a valid AES/EBU signal although the signal is
silent.
