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.
• Check to ensure the Voltage Select Switch for the AC Mains is set to match your location
If the AC mains voltage is higher than the E8B’s selected voltage, it is
possible that the fuse needs to be replaced. See the information that came with your
monitor for more information.
• The KRK logo is illuminated on the front panel of the E8B. 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 to the monitor back on. The power light should
illuminate.
• If a fuse change was required and, upon powering the monitor back up, the fuse blows
again, please contact KRK technical support.
Problem: If you can’t hear any sound…
• Repeat the steps in the previous troubleshooting section above before continuing to the
next steps.
• Check to see if all other audio devices using the same AC outlet are still operating.
• Make certain 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 nonworking
monitor to the working unit. This will determine whether it's really the monitor, a faulty
cable, or some other glitch in the audio chain.
• If the monitor is still not responding, please contact KRK technical support.
Problem: If the monitor suddenly stops working…
• Turn the monitor send down or off.
• Repeat the 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 its 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 Exposé provides maximum circuitry protection against AC power surges, amplifier
overdrive, and overheating of the amplifiers. Turn the monitor off and 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, please contact KRK technical support using the
dedicated Expose customer support line created just for Expose customers. The
number is 954 316-1KRK (or 954 316-1575).
