MartinLogan Speaker user manual Multi-Channel Mode, Signal connection for 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):

1Connect 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):

1With multi-channel source material playing, adjust the Level control to your preferred level.

2Try 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°.

3If 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.

4Follow the bass management setup instructions in your processor manual to fine-tune the subwoofer level.
