This setup is recommended if your Dynamo 1000 will be
used in a dedicated home theater or multi-channel system.
When a signal is connected to the subwoofer’s LFE input, and
the crossover switch is set to 'Bypass (LFE In)' the internal low
pass filter is not active. By following this setup, you will allow
your processor to handle most of the bass management.
If you will be using your system for both 2-channel and
multi-channel listening we recommend using this setup
and connection method. Some modern receivers and
processors allow users to route left and right channel
low-frequency information, in addition to discrete LFE infor-
mation, through the LFE output.
Signal Connection (see figure 4):
1 Connect the LFE output of the processor to the LFE input
using a quality RCA interconnect.
WARNING!
Based on the performance of most proces-
sors, it is recommended that MartinLogan
center and effects type speakers (i.e. Motif,
Matinee, Stage, etc.) not be run in large,
wide, or full range mode. Doing so may
potentially damage the speaker if the proces-
sor 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 LFE
channel to your main and/or surround speakers.
We recommend that you do not use this option.
Recommended Control Settings (see figure 5):
1
Set the crossover switch to 'Bypass (LFE In)'
.
2 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
manual to fine-tune the subwoofer level.
3 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,andLow-
Pass: 24dB. The optimal setting for these options may vary
depending on your room and listening preferences.
4 Adjust the phase control until ideal blending is obtained. If
you hear no discernible difference leave the phase at 0°.
5 Follow the instructions in your processor manual to fine-
tune the subwoofer level
