Compliance to FCC Rules

This device complies with part 15 of the FCC Rules. Operation is 
subject to the following two conditions: 

• 

This device may not cause harmful interference, and

• 

This device must accept any interference received, including  

 

interference that may cause undesired operation. 

Note: This equipment has been tested and found to comply with 
the limits for a Class B digital device, pursuant to part 15 of the 
FCC  Rules.  These  limits  are  designed  to  provide  reasonable 
protection  against  harmful  interference  in  a  residential 
installation. This equipment generates, uses and can radiate radio 
frequency  energy  and,  if  not  installed  and  used  in  accordance 

with  the  instructions,  may  cause  harmful  interference  to  radio 
communications. However, there is no guarantee that interference 
will not occur in a particular installation. If this equipment does 
cause harmful interference to radio or television reception, which 
can be determined by turning the equipment off and on, the user 
is encouraged to try to correct the interference by one or more of 
the following measures: 

• 

Reorient or relocate the receiving antenna. 

• 

Increase  the  separation  between  the  equipment  and 

 

receiver. 

• 

Connect  the  equipment  into  an  outlet  on  a  circuit  different 

 

from that to which the receiver is 

 

connected. 

• 

Consult the dealer or an experienced radio/TV technician for 

 

help.

Modifications not expressly approved by the manufacturer could 
void the user’s authority to operate the equipment under FCC 
rules.

System

Genelec  SE7261A  DSP  Subwoofer  is  designed  for  precise 
monitoring of 24 bit/192 kHz AES/EBU digital audio signal. It is 
fully compatible with Genelec GLM.SE™ Loudspeaker Manager 
Software  and  the  proprietary  Genelec  loudspeaker  control 
network and Genelec 810A digital input loudspeakers.

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.

Using the SE7261A in  

Stand-Alone Mode

When the subwoofer is not connected to the Genelec loudspeaker 
control  network,  it  operates  in  stand-alone  mode  and  only  the 
functions actuated by the controls on the connector panel can be 
used. However, the settings made with the GLM.SE™ software 
can  be  saved  into  the  subwoofer  and  applied  even  when  the
