Power on
When you first power up the V Series, there is a 3 second delay and the light on the front of the
unit comes up and then one second later there is signal to the speakers. The same is true for
coming out of standby.
Standby
Your monitors have the ability to power down when you are not using them for 30 minutes. If you
don’t want them doing that, you simply switch the standby feature off on the back. But if you use
standby to save energy or because the power switches are hard to reach in your studio, leave the
standby on. You will know that the Vs are in standby because the KRK logo will pulse (even if you
normally have the KRK logo light off).
To wake up your monitors after they go into standby. Just like when you first turn them on, there is
a three second delay until the light on the front comes on and a second later you get signal to the
speaker. If your speakers go into standby, ease your source volume up slowly. You only have to
break -50 dBu for them to come out of standby. This will keep you from excessive volume spikes if
you ease it up slowly. Also, as you raise the volume, you can use the light going solid as an
indication to turn your source back down to avoid any loud spikes. Or if your setting is KRK logo
light out, you can use the pulsing light going off to indicate you are about a second from the
speaker coming on.
TROUBLESHOOTING
If there is no power, check to see if...
· Check to see if the power cord is plugged into both the IEC socket on the rear panel of the active speaker and into the AC mains.
Verify that the AC mains are active by using an approved AC tester or simply connect a lamp with a working light bulb. In some cases,
the AC mains may be controlled by a light switch or power strip with suppressor that may not be in the ‘on’ position.
· Verify that the power switch on the active speaker is in the ‘on’ position.
· Check to see if the power light is illuminated. The power light is the KRK logo on the front panel of the monitor. If
the power light is not illuminated, turn the power switch OFF and check the A/C mains fuse(s). The fuse is located
directly below the power receptacle.
· Be sure that dipswitch 4 on the back of the unit is in the up position.
NEVER USE A LARGER AMPERAGE FUSE THAN SPECIFIED!
· After the fuse has been checked and replaced, turn the power switch back on. The power light should illuminate.
· Check to see if a fuse change was needed. If you power the monitor back on and the fuse blows again, the monitor needs to be
returned to the dealer or distributor where you purchased it or to KRK for servicing.
If you can’t hear certain sounds...
· Repeat 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.
· Check to see if the audio source cable is plugged into both the source output and the monitor input.
· Check to see if 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.
· Check to see if the audio source is in mono or stereo, or information in the mix may also be panned differently which will result in
differing cancellation. Audio heard in stereo and not heard in mono may be a result of phase cancellation due to long delays
between left and right channels or polarity inversion. Avoid polarity inversion by using matching cables.
· Check to see if one of the monitors is working. Exchange the audio input cable from the non-working 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, it should be returned to the dealer where you purchased it or to KRK for servicing.
If the monitor suddenly stops working...
· Turn the monitor level 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 monitor provides maximum circuitry protection against AC power surges, amplifier 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 where you purchased it or to KRK for servicing.
