1Standby button & LED indicator
The front panel Standby button will toggle the preamplifier between operate, its fully operational state, and a standby mode that leaves the preamplifier off, yet ready to respond to system commands via any of the supported control options (e.g. IR input, DC trigger,
The current state of the preamplifier is indicated by the LED indicator in the center of the standby button. When the unit is powered and switched on, the state of this LED indicates the following:
• | on | = | standby |
• | flashing (on | = | initialization |
• | off | = | operate |
• | on (dim) | = | display timeout |
• | flashing (after | = | AC mains voltage out of range |
If you are planning not to use the preamplifier for an extended period of time, e.g. vacation or other travel, we suggest you disconnect it from the AC mains. Please be certain that the preamplifier is turned off prior to disconnecting it from the AC mains.
Also, it is a good practice to physically disconnect any and all valuable electronics from the AC mains during electrical storms, as a lightning strike anywhere near your home can put a tremendous surge on the AC mains that can damage any piece of electronic equipment, no matter how well designed and protected. The best protection in the case of severe electrical storms is simply to remove the electronics from any connection with the power grid.
