3)  “Out Filter”: The preamp output is filtered by a 

fully variable, active filter incorporated into the 
output section and is not affected by the bass 
control processing selected for the amplifier.

The 600/1v3 includes a versatile bass 

processing section consisting of two 
primary components: a fully variable, 
24 dB per octave infrasonic filter and a

1)  “Infrasonic Filter”: The infrasonic filter is a  

24 dB/octave high-pass filter, with a fully

be an audible effect, but one which may be 
desirable for SPL competition purposes or curve 
shaping of a bottom-heavy system. With ported 
enclosures, the use of the infrasonic filter is 
highly recommended to protect the speaker(s) 
from excessive excursion below box tuning. 
With sealed enclosures, the use of the filter is 
less necessary, but can still help protect the 
speaker system. If you would like to select the 
infrasonic filter frequency with a higher level of 
precision, consult Appendix C: Chart A-3 (page 
17) of this manual. The infrasonic filter can be

2)  Precise Frequency Selection: The filter 

frequency markings on the front panel of 
the amplifier are for reference purposes and 
are generally accurate to within 1/3 octave 
or better. If you would like to select the filter 
frequency with a higher level of precision, 
consult Appendix C: Chart A-1 (page 16) 
of this manual. This chart gives you a more 
accurate frequency for each of the forty 
detented positions of the frequency selection 
control. This method can be very useful if the 
amplifier is mounted in a location where you 
can’t see the front panel markings easily.
