High Pass Crossover
The 200 Pre High Pass Crossover for the Main Outputs allows you to block low frequencies from going to your
main L and R speakers. This can be particularly useful if you are using small speakers (typically with woofers
that are 6.5”/165
mm or smaller) and you have a subwoofer. The most common settings are between 50
Hz
and 80
Hz. If you are not using a subwoofer you will get better results by turning the 200 Pre High Pass
Crossover off or setting it at 40
Hz or lower. If you want your L and R speakers to operate full range with no
frequencies blocked set the High Pass crossover switch to the Off position.
Subwoofer Setup
For proper subwoofer operation you must first pick the subwoofer output most appropriate for your system and
adjust your subwoofers built in crossover as needed. After picking the correct crossover you must setup the
subwoofer level.
>80Hz Subwoofer #1 Output (Low Pass)
If you are connecting your subwoofer to the 200 Pre’s “>80Hz” Sub output then you should turn off the
crossover built into your subwoofer. Using both the sub’s and 200 Pre’s crossovers will result in low output
caused by “double-filtering.” Most powered subwoofers have a switch that’s typically labelled “Bypass”, “LFE”
or simply “Crossover Off.” If your subwoofer’s crossover cannot be switched off, set it to its highest frequency.
Full Range Subwoofer #2 Output
If you are connecting your subwoofer to the 200 Pre’s “Full Range” Sub output then you must leave your
subwoofer’s crossover engaged.
Subwoofer Level Setup
To set the proper subwoofer level, start with the 200 Pre’s subwoofer level control set to its flat (0
dB) position
and play a variety of music. Adjust the level control on your subwoofer until the bass level sounds balanced in
your system. Now, whenever you want to fine tune your subwoofer level you can simply use the 200 Pre’s
front panel or remote-control Sub level control instead of walking over to your sub, bending down and reaching
behind it to adjust its level control.
Using Stereo Subwoofers
If you have two subwoofers and want them to operate in stereo you can connect them to the Left and Right
Main Output jacks instead of to the Sub Output jacks which are mono. In this case you need to set the High
Pass crossover switch to Off. With this configuration the 200 Pre Sub Level control and on/off by remote do
not function.
