This setup is recommended if your Dynamo 700 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):

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,andLow-

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
