Subwoofer Setup
The crossover setup and level setup are two important steps in setting up your sub(s).
Subwoofer Crossover Setup
You will want to turn off the crossover built into your subwoofer's amplifier since the Halo Integrated
has its own crossovers and leaving both the sub and Integrated’s crossovers on will result in double
filtering which restricts the sub output. Most powered subwoofers have a switch that might be
labelled “Bypass”, “Home Theater” or simply “Crossover Off.” If your subwoofer’s crossover cannot
be switched off, set it to its highest frequency. Follow the Crossover setup section for the proper
settings.
Subwoofer Level Setup
To set the proper subwoofer level, start with the Halo Integrated’s front panel Sub Level control set
to its 12 o’clock (0 dB) position and then play a variety of music. Adjust the level control built into
your subwoofer until the bass level sounds balanced. Now, whenever you want to fine tune your
subwoofer level you can simply use the Halo Integrated's front panel Sub Level control instead of
walking over to your sub, bending down and reaching behind it to adjust its level control.
High and Low Pass Crossover Setup
The Halo Integrated is equipped with adjustable low pass
and high pass crossovers. Crossovers are filters that allow
certain frequencies to pass while blocking other
frequencies. A low pass filter permits low frequencies to
pass and blocks high frequencies. A high pass filter permits
only high frequencies to pass and blocks low frequencies.
80 Hz is the best starting frequency for both the high and
low pass crossovers if you are using a subwoofer and are
not sure where to set the crossover frequency. If you are
not using a subwoofer, set the Pre Output Crossover switch
to the Off position. The Speaker Outputs and the Pre
Outputs (both RCA and XLR) are affected by the crossover
settings.
Low Pass Crossover (Subwoofer RCA and XLR Outputs)
The Low Pass crossover allows only low frequencies to be output from the Halo Integrated
Sub Output jacks.
Note:
If your subwoofer has a built-in crossover that cannot be switched off, set it to
its highest frequency to minimize the negative effects on bass response from
filtering in the Halo Integrated and again in the subwoofer.
High Pass Crossover (Left and Right Speakers and Pre Outputs)
The High Pass crossover for the Speaker Outputs and Pre Outputs (both XLR and RCA)
allows you to prevent low frequencies from going to your main L and R speakers. This can be
particularly useful if you are using small speakers (typically their woofers 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 the best results by turning the High Pass
crossover off or setting it below 40 Hz. If you want your L and R speakers to operate full range
with no frequencies blocked set the High Pass crossover switch to its Off position.
