7. read the safety warnings to avoid hazardous operating conditions The unit must be disconnected from the AC power source before any work is done on it Refer all servicing to qualified service personnel SUNLIGHT HEAT Avoid prolonged exposure to direct sunlight as this may cause the unit to overheat and thermally shut off Excessively hot operating conditions can also cause a thermal shutdown Do not store in extremely hot or cold conditions or extremely high humidity Always allow unit to come to room temperature before use CLEANING Never clean the Impulse 12D while plugged in or turned ON When the unit has been fully disconnected from AC power sources use a dry cloth to remove soil or other dirt Never use strong solvents on the Impulse 12D as they could damage the cabinet Do not allow ANY fluids to drip inside the Impulse 12D TOUCHUP For an overall finish enhancement and protective coating use gloves to apply a plastic finish protector such as Armor All protectant or a similar product to the surface of the plastic cabinet only Note that the cabinet will be slippery after these treatments rub them down vigorously with a dry lint free cloth to minimize this CHECK FOR SECURE HARDWARE After the first few months of use and periodically thereafter check the hardware of the Impulse 12D for tightness including the rear panel screws and the screws that hold the baffle and rear cabinet together The unit is subject to a

MIC LINE SWITCH ADJUSTMENT The mic line switch 5 6 provides for the increased gain needed for microphone use into the two inputs Set the Mic Line switch to in for line level signal use and set it out for mic level use The associated LED indicator 11 12 which is located to the upper right of the switch will glow green for a line level setting and red for a mic level setting The unit is normally shipped with the button in the line level or in position However before each use it is a good idea to check for the proper position of the switch as it could be toggled inadvertently during transport or set up Due to the 3o dB of extra gain that this switch provides DO NOT leave it in the out position for line level input signal use This could result in input stage clipping of the Impulse 120 and cause unnecessary distortion DISCONNECTING AC POWER TO THE IMPULSE 12D We recommend that the Power switch 3 be used to turn the unit off first and then the AC power cord can be removed This minimizes stress to the power amplifiers and the transducers from turn off transients The power switch has an arc Suppression capacitor to help during turn off and tends to make a clean disconnect from the AC power while the power cord IEC connector can make intermittent contact before finally becoming fully disconnected e g as when wiggling the cord TROUBLESHOOTING No Output at All First make sure the unit has AC power a
