Extended low frequency response (The MC44C401L frequency response extends below 25 Hz)
Simple passive interface to Motorola’s MC44BC374 (UHF/VHF) and MC44BC375 (VHF) modulators
Preservation of original surround sound fidelity
System performance not impacted by copy protection technologies
Enables lower system component count, smaller board size, and significantly lower overall system cost
Eliminates manual alignment of filters, phase controls, and composite signal amplitude
