1. a EE Ela E a allel EE E NOTES ABOUT HUM While the AMP1200 has been designed to minimize the possibility of hum in the audio system it is still possible that a hum will occur in rare circumstances Its safety grounding can create a path for small amounts of 60 Hz energy to travel trough the line level audio system While not dangerous this energy can cause difficulty with the auto signal sensing circuit and at the very least will interfere with the quiet enjoyment of your system The first course of action should be trying to make sure that all ofthe audio components are connected to either the same electrical outlet or at least into the same circuit branch Next cable TV systems are notoriously the culprit so be sure to try disconnecting all coaxial feeds that are connected to the system If this solves the problem install a coaxial line isolator and reconnect the system In the very worst case a line level audio isolator transformer connected to the line in ofthe subwoofer amplifier will usually solve the problem Important Safety Instructions To reduce the risk of electric shock do not remove cover No user service able parts inside Refer servicing to qualified personnel To reduce the risk of fire and shock do not expose unit to rain or moisture The unit should be connected to an earth grounded AC electrical socket The unit s2.

3. ADGES Em o DC E E OS FRONT PANEL 1 Master Power Switch Indicator LED Front panel pushbutton power switch turns the amplifier on and off When the switch is on and the indicator LED is red the amplifier is in standby mode The remote turn on switch located on the rear is either in the trigger or auto position When the LED is blue the amplifier is fully active The master power switch will turn off the am plifier no matter which power mode has been selected 2 Zone Status Indicators Each pair of channels or zones has a bi color LED to indicate its operational status These indicators provide quick and easy troubleshooting of the system If the circuitry deter mines that a channel must be shut down due to excessive heat or low impedance a short only the channels that are affected will be turned off causing the zone LED to turn red The remaining zones will continue to operate and maintaina blue LED status Once the condition has been corrected for the zone in question the status LED will return to blue Note When the power LED is red and the zone status LEDS are not lit off indicates the unit is in stand by mode REAR PANEL 3 BUS Line Inputs Outputs The AMP1200 has two common or BUS inputs that receives audio signals from standard line level audio sources and sends them to any or all channels The BUS line outputs are direct feed through to allow the BUS inputs to be fed to o
