HOW TO
INSTALL PRE-LOADED ENCLOSURE
Use the appropriate settings on your amplifier/dsp when connected to your SPL enclosure.
If you remove the AST connector, you have several setting options you can use. Some
include active crossover settings and some are pure full range amplifier setups. See the
recommend crossover settings below.
TWEETER AMPLIFIER (OPT. 1):
Set the switch to FULL, the internal passive cross over will used.
Benefit here is that you can use a full range amplifier without any
need for active filter. Compared to passive mode you can still
change the level/gain between woofer and tweeter as you use
different amplified channels.
TWEETER AMPLIFIER (OPT. 2):
Set high pass filter to 4kHz and the switch to HP/HPF mode. This
way your connected tweeters will have an extra protection below
the passive cross over point and the sound can be tailored toward
your own preferences depending on the chosen active filter
frequency. Both the passive and active crossover is in use with
option 2.
MIDRANGE/WOOFER AMPLIFIER (OPT. 1):
Set the high pass filter to 120Hz (PB1-46) or 100Hz
(PB1-48) and the switch to HP/HPF mode. Compared to
passive mode you can still change the level/gain
between woofer and tweeter as you use different
amplified channels. WARNING! Switch to FULL setting
or lowering your high pass crossover point can damage
your speakers and is not recommended.
MIDRANGE/WOOFER AMPLIFIER (OPT. 2):
Set HP/HPF to 120Hz (PB1-46) or 100Hz (PB1-48) and the
LP/LPF to 4 kHz. Set the crossover switch to LP/LPF
mode. This way your connected midrange/woofers will
play from 120/100Hz to 4 kHz and your connected
midrange/woofers will have a protection below the
chosen HP/HPF setting and the sound can be tailored
toward your own preferences depending on the chosen
LP/LPF filter frequency.
