Front L/R
Select LARGE for full-range front speakers to deliver full frequency
response to the front left and right outputs. Selecting SMALL activates
a 12dB per octave highpass filter and automatically routes low fre-
quency information to the subwoofer output. Choices of 40, 80 and
120 Hz are available for the -3dB point. The SMALL setting is recom-
mended unless your speakers are capable of handling full audio
signals, or are equipped with their own crossovers. This setting should
be on SMALL at 80Hz for ALL JBL Synthesis systems.
Speaker Configuration
The Speaker Configuration menu allows a wide range of choices in

subwoofer, as well as a highpass filter for all other speakers. The two
selections are for CUSTOM or THX configuration.
