MartinLogan Speaker - Manual (Page 7)

Multi-Channel Mode
This setup is recommended if your Abyss will be used in a
dedicated home theater or multi-channel system . When a
signal is connected to the Abyss’s LFE input, Abyss’s inter-
nal low pass filter is not active . By following this setup, you will
allow your processor to handle most of the bass management .
Signal .Connection .(see .figure .4):
1 Connect the LFE/0 .1 subwoofer output of the processor to
the LFE input of the Abyss using a quality RCA interconnect .
WARNING!
Based on the performance of most processors,
it is recommended that MartinLogan center and
effects type speakers (i .e . Cinema i, Theater i and
Script i) not be run in large, wide or full range mode .
Doing so may potentially damage the speaker if
the processor attempts to drive the speaker beyond
its rated frequency range . This warning also
applies to products from other manufacturers .
It is recommended to run center and effects type
speakers in limited or narrow mode .
Some processors have an option to route the 0 .1
channel to your main and/or surround speakers .
We recommend that you do not use this option .
Recommended .Control .Settings .(see .figure .5):
1 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 pro-
cessor manual to fine-tune the subwoofer level .
2 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 .
3 Adjust the phase control until ideal blending is obtained .
If you hear no discernible difference leave the phase at 0° .
4 Follow the instructions in your processor manual to
fine-tune the subwoofer level .
