• Protective Circuits

The unit is equipped with protective circuits to protect the amplifier circuits and headphones against damage. If a protective circuit trips, the sound is instantly muted. In this case, "PROTECT" flashes on the display and the OPERATE indicator also flashes. To release the protective circuits, switch the power OFF, and wait for approximately 1 minute before switching the power back ON again.

• At Power ON

For about 8 seconds after the power is switched ON, a protective circuit trips and mutes the sound to give amplifier circuits time to stabilize. Once the amplifier circuits stabilize, the protective circuit releases and audio is enabled.

• If Strong Bass Signals Are Input

A protective circuit trips if bass signals of an excessive level are detected. A protective circuit also trips if an abnormality caused by such reasons as an amplifier fault is detected in the power supply circuit.

• Error Messages

When multiple SC-11S1s are connected by F.C.B.S., the below error messages may appear on the display. In these cases, there is a problem with the ID number setting or remote cable connection. Check the ID numbers and remote cable as indicated in the below table. For details on how to set ID numbers, see HOW TO SET 10 NUMBERS on pg. 27.
