Using an A/V processor and the Dynamo’s low pass filters.
This setup is recommended if your Dynamo 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 Dynamo 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 Dynamo 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.
