2-Channel/Multi-Channel Mode
Using an A/V processor and the Abyss's low pass filters .
This setup is recommended if your Abyss will be used in
both 2-channel mode and as a LFE (0 .1) channel in a
multi-channel mode . By following this setup, you will
allow your processor to handle most of the bass manage-
ment while running in multi-channel mode, and relinquish
control of the low pass filter to the Abyss when running in
a 2-channel mode .
Signal .Connection .(see .figure .6):
1 Connect the left and right outputs of your preamplifier to
the left and right inputs of the Abyss using quality RCA
interconnects . If your preamplifier only has one set of
outputs you need to obtain Y adapters from your dealer .
2 Connect the LFE/0 .1 output of the processor to the LFE
input of the subwoofer using quality RCA interconnects .
Recommended .Control .Settings .(see .figure .7):
1 Set your front speakers for wide, large or full mode in your
processor . Set the center and effects type speakers in
limited or narrow mode (see the warning on page 7) .
2 Set the low-pass filter switch to the closest option equal to
70% of your loudspeakers lowest frequency response .
3 While playing music with bass content, turn the level control
up until the music has deep bass that is not overwhelming .
4 Try the phase control in different settings until the best
blending is obtained . If you are augmenting MartinLogan
loudspeakers, we suggest you start with the phase set
at 90° .
5 Use the bass management section of your processor's
speaker level setup option to set the subwoofer level
at an appropriate level . Follow the instructions in your
processor's manual to fine-tune the subwoofer level .
6 If your processor offers the option to setup crossovers for a
subwoofer, we recommend that you start with the following
settings—Crossover: 70Hz, High-Pass: 12dB, and Low-
Pass: 24dB . The optimal setting for these options may vary
depending on your room and listening preferences .
