Q: What does LFE mean on the Martin Logan Dynamo 300 and how do I use it?

LFE stands for "Low Frequency Effects" - it is the channel dedicated to low-frequency effects in home theater audio systems. On the Martin Logan Dynamo 300, this corresponds to the separate LFE input (specific RCA connector). The Dynamo 300 has three connection modes: Line input (left/right RCA) - for simple integration with amplifiers Speaker input (binding posts) - for direct chaining LFE input (dedicated RCA) - for home theater with AV processor Setting up in LFE mode: Switch the bypass switch to "LFE In". In this mode, the internal low-pass filter of the subwoofer is disabled, allowing the AV processor to manage the bass handling. Set the low-pass filter to 150 Hz and let your processor handle the crossover (typically 70 Hz with 12 dB high-pass and 24 dB low-pass filtering). Important: Do not connect the speaker and line inputs simultaneously - choose only one connection mode.
