Centralized bass management System setup The centralized bass management method uses fixed 85 Hz crossover filters in the analog output channels in the 7380A SAM subwoofer for the signal feeds going to monitors. All analog signal cables are first routed to the subwoofer's IN connectors and then from the OUT connectors to the respective main monitors. The outgoing signal has the low frequencies removed.
3 4 85 Hz 85 Hz Figure 3. The effect of phase difference between the subwoofer and the main monitors Incorrect phase alignment can cause a drop in the audio level at the crossover frequency. Correct phase alignment eliminates this level dip. See chapter "Setting the Phase Switches." The DIGITAL LFE switch selects the low pass frequency for the LFE signal (see "LFE CHANNEL" below). The possible frequencies are 85 Hz for "OFF" position and 120 Hz for "ON" position.
• If the +10 dB LFE gain is already implemented by another device, for example, a surround sound processor or the output matrix of a mixing console. • When producing an audio format that does not require the use of +10 dB gain on the LFE channel. +100 Level vs Freq (Hz) Bass Roll-Off -4, -8 and -12 dB 7380A 11.5.
