MartinLogan's engineering and design team developed the
Abyss for easy setup and system integration . Before
beginning to connect your Abyss, please review the
controls discussed in the last section . An understanding
of these will help speed you along as you connect and
integrate your Abyss with your system . All signal
connections are done at the signal input section on
the rear connections panel of the Abyss . Make certain that
all of your connections are tight .
WARNING! Turn your Abyss subwoofer to
standby before making or breaking any signal
connections!
2-Channel Mode
This setup is recommended if your Abyss will be used in a
2-channel system with main speakers playing full range .
When a signal is connected to the Abyss’s left/right inputs,
the Abyss’s internal low pass filter is active .
Signal .Connection .(see .figure .2):
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 may need to obtain Y adapters from your
dealer .
Recommended .Control .Settings .(see .figure .3):
1 Set the low-pass filter switch to the closest option equal to
70% of your loudspeakers lowest frequency response .
2 While playing music with bass content, turn the level con-
trol up until the music has deep extended bass, being
careful to avoid levels that become overwhelming .
3 Try the phase control in different settings until the best
blending is obtained . If you are using the Abyss to aug-
ment other MartinLogan products, we suggest you start
with the phase set at 90° .
