SYSTEM CONNECTOR (Pin 90 of IC701)
1. Pin 3 of the system connector (CN602) detects if the subwoofer is equipped / not equipped / faulty.
• When the system connector is connected correctly and the subwoofer is operating properly, approximately
4 to 5V voltage is obtained.
• When the system connector is not connected, approximately 2.5V voltage is obtained.
• When the protection circuit of the subwoofer is at work, approximately 0 to 2V voltage is obtained and
the protection circuit of AV-S70 works together with it.
2. When the system connector is not connected or the power of the subwoofer (NX-SW70) is not turned ON, only VIRTUAL
SURROUND and MONO MOVIE functions of the sound field program are available.
