TROUBLESHOOTING
PROBLEM: IF THERE IS NO POWER, CHECK TO SEE IF...
• The power cord is plugged into both the IEC socket on the rear panel of the unit and into the AC mains
• The AC mains voltage is matched to the operating voltage require- ments See Changing Voltage in the Connecting the System section on page 5). If the AC mains voltage is higher than the iKEY Audio monitor is selected voltage it is possible that the fuse needs to be replaced. (See Changing Fuses in the Connecting the System section on page 5).
• The power light is illuminated on the front panel of the Ikey audio. If not, turn the power switch OFF and check the A/C mains fuse(s). NEVER USE A LARGER AMPERAGE FUSE THAN IS SPECIFIED! Turn the power switch back on. The power light should illuminate.
• If a fuse change was needed and upon powering the monitor back up the fuse(s) blow again, the monitor needs to be returned to the dealer you purchased it from or to IKEY AUDIO Monitor for servicing.
PROBLEM: IF YOU CAN'T HEAR ANY SOUND...
• Repeat steps in the previous troubleshooting section above before con- tinuing to the next steps.
• Check to see if all other audio devices using the same AC outlet are still operating.
• MAKE SURE THAT:
• The audio source cable is plugged into both the source output and the monitor input.
•The system gain pot is turned up fully clockwise (+ 6 dB).
•The signal source (E.g. mixing console, work station, CD player, etc.) is turned up to a level that can properly send a signal to the monitors.
•If one of the monitors is working. Exchange the audio input cable from the
•If the monitor is still not responding, it should be returned to the dealer that you purchased it from or to IKEY AUDIO for servicing.
PROBLEM: IF THE MONITOR SUDDENLY STOPS WORKING...
• Turn the monitor send down or off.
• Repeat steps in the troubleshooting sections above before continuing to the next steps.
• Carefully check to see if the amplifier's back plate is hot! If the monitor has been running at highest power output for an extended period of time, it could be that the unit has become overheated and the protection circuitry has shut the system down momentarily. The Ikey audio monitor provides maximum circuitry protection against AC power surges, amplifi- er overdrive, and overheating of the amplifiers. Turn the monitor off then wait 30 minutes to allow the back plate to cool down. Turn the power switch back on.
• Increase the volume to check for normal operation.
• If the monitor is still not responding, it should be returned to the dealer that you purchased it from or to IKEY AUDIO for servicing.
Problem: The sound quality changes... • Repeat steps in the previous trou-
bleshooting section above before continuing to the next steps.
•Disconnect the signal cable at the input of the monitor. With power on, place your ear close to each driver (tweeter/woofer) and listen for
noise (i.e., a slight hiss or hum). If there's absolutely no sound whatsoever, it could be that one or more of the drivers (woofer or tweeter or both) is at fault. It's also possible that the problem lies some where in the elec- tronics.
•Play some
•Cover the woofer so you can hear mostly the tweeter. Is the tweeter producing a clear sound? If there is not a clear tonal quality or any sound at all then the tweeter probably needs to be replaced.
•Once you have a better idea of what may be at fault then call us and speak with someone in the service department. They will help you deter- mine the best solution to correct your monitors.
PROBLEM: THE MONITOR HISSES, HUMS OR MAKES OTHER LOUD
NOISES...
Here are some suggestions that will help you eliminate these undesirable from your system:
•Make sure that the power cord is plugged snugly into the IEC socket on the rear of the monitor.
•Check the connections between the signal source and the monitor. The Ikey audio's XLR and TRS connector is a completely balanced system. If you're connecting an unbalanced output to the monitor, be sure that you're using PIN 2 for signal and have PIN 1 and PIN 3 tied together at the source end.
•Refer to the Connecting the System section on page 4 of this manual to ensure that the AC mains is matched to the operating voltage require- ments.
•All audio equipment should use the same ground point. Check all other devices using the same AC output in the building like dimmers, neon signs, TV screens, and computer monitors. These devices should not be using the same circuit. .
