MartinLogan Descent i [10/28] Multi channel mode

Multi-Channel Mode

This setup is recommended if you will use your subwoofer

in a dedicated home theater or multi-channel system. When

a signal is connected to the subwoofer’s LFE In, the Low

Pass Filter control is NOT active. Your processor handles

most of the bass management.

Signal Connection (see figure 6—RCA shown):

1 Connect the LFE out of the processor to the LFE In. Use

either an RCA or an XLR interconnect.

WARNING!

Based on the performance of most processors,

it is recommended that MartinLogan center

and effects type speakers (i.e. Stage, Cinema,

Theater, and Script i) not be run in large, wide or

full range mode. Doing so may potentially dam-

age 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.

Recommended Control Settings (see figure 7):

1 With multi-channel source material playing, adjust the

Level control to your preferred level.

2 Try the phase control in different settings until the best

blending is obtained. If you are using the subwoofer to

augment other MartinLogan products, we suggest start-

ing with the phase set at 90°.

3 If you have completed steps 1–2 and still have weak

or boomy bass, adjust the 25Hz Level and 50Hz Level

knobs to compensate for these anomalies. Increase and

decrease to controls and listen to the effects. Try to find

a position that sounds correct to you. Experiment by

changing the Level control while adjusting these knobs.

Find a position that gives you deep extended bass and

good blending with your main speakers.

4 Follow the bass management setup instructions in your

processor manual to fine-tune the subwoofer level.
