E4 in standby mode You can check that the power has been removed from the E4 or that you experienced a power dropout Sleep Mode The host microcontroller has told the amplifier and power supply to turn off This only occurs in conjunction with another alarm usually AC power fault because it in itself is not an alarm condition When an AC power dropout occurs the amplifier immediately shuts the amplifier and speaker relay off then the other processing is shut down This all happens fast enough to prevent data loss or corruption and to prevent loud pops in the speakers When this occurs you should check the alarm history to determine what other faults occurred at this time High Frequency Sense Fault This protection mode is designed to prevent damage to the amplifier or speakers from excessive high frequency audio or ultrasonic energy The amplifier is not capable of sustained operation at full power in the 10kHZ to 20kHz range Generally this fault results in a one time 3 second dropout If when the amplifier tries to restart after 3 seconds the excess HF is still present the amp and speaker relay will remain off for another 3 seconds and the loop repeats Six of these in a row will cause the amp to shut down and will trigger a Retry Fault When this fault occurs you can check your program material for excessive high frequency content or for a potential ground loop which has created an oscillation internal to the E4 unit Y
