When you set the LFE Main to “Yes” or “On,” the receiver sends the LFE signal to both the subwoofer and the main speakers. This allows the main speakers to produce the low-frequency effects along with the subwoofer, creating a more cohesive and engaging audio experience.
How Does Denon LFE Main Work?
So, how does Denon LFE Main achieve this harmonious blend of low-frequency effects? Here’s a step-by-step breakdown:
Signal Processing
When you set the LFE Main to “Yes,” the receiver processes the audio signal differently. Instead of sending the LFE signal only to the subwoofer, it splits the signal between the subwoofer and the main speakers.
Low-Pass Filtering
The receiver applies a low-pass filter to the LFE signal, which allows only the low-frequency components (typically below 80 Hz) to pass through to the main speakers. This ensures that the main speakers are only reproducing the deep bass notes, leaving the higher frequencies to the tweeters and mid-range drivers.
Speaker Crossover
The receiver also sets a crossover point, typically around 80 Hz, which determines the frequency range that the main speakers will handle. Any frequencies below this point are sent to the subwoofer, while frequencies above it are handled by the main speakers.
