Question about Kustom KPC10MP 10" Powered Monitor Speaker

1 Answer

I have 2 Kustom KPC10MP powered speakers - very new. One has developed a hiss that increases with volume, regardless if there is signal going into the speaker or not. This is a new development as of today. Heard a small pop while working with the soundboard (running low level music through the speaker system) and then a very annoying hiss (static-like sound). The music still comes through but the hiss is constant.

Hopefully you were powering ALL interconnected equipment from the SAME receptacle. People can destroy the input circuit of powered speakers by plugging them into a receptacle at the stage and then powering the mixer from another receptacle... Pro's know to power ALL interconnected equipment from the same source, be it a receptacle or a power conditioner to avoid ground bounce damage to equipment. They carry power from the stage back to the mixer on an extension cord. You may have had a static discharge that blew one side of the balanced input of the speaker. The parts are inexpensive, however the labor to get at the amp is usually not fun. I have the dual 10 powered Kustom's and one gets at the POWER amp via removing the speaker after the grille... HOWEVER that is to get at the power amp. The Preamp is probably the failure and it is right at the input plug area and you can get at that by removing the panel with the plugs and power switch and volume control.
I don't have the schematic. Look for shorted RF bypass caps on one side of the balanced input circuit and possibly a damaged input op amp.

I have got a kustom KPC10mp and i am trying to hook it up to a kustom non- powered and i cant get no sound thru the monitor , Can this be done .The line out dont make no sound when it is connected to the...


In a word, NO. The line out is line level audio... it has NO power amp and cannot drive a non-powered speaker. I have both of these cabinets myself. You need to use an amp with the non-powered speaker. When using an external amp you will need to make sure you phase the two speakers correctely... you could just reverse the speaker leads of the non-powered one if needed.

Hi! I need two input/output plates for my Kustom floor monitors (KSC10ML). By input/output plate, I mean the unit that has the volume knob plus the two input/ output jacks that is screwed ino the side...


The KSC10ML has NO volume control... only two 1/4 inch jacks. To get a matching "jack cup" you will probably have to go to Kustom. I have searched for the item on the web and only jack cups that seem to come up are for Marshall or ones that use binding posts. I found one blank one but it is 5 by 7 inches... too big for that Kustom cabinet. In a pinch if you don't need it to be recessed, cut metal or ABS plastic plates and drill for two jacks.

Have you tried connecting a single speaker to each output and cutting the volume down to see if you have a load or impedance problem? The amp may be perfectly fine except it's trying to play to a 2 ohm or less load :-)

I have a Peavey 8600 amplifier. It sounds great but when only operating vocals, in order to get the highs of your voice just right, the speakers put off a large amount of white noise. While singing, you...


There is not enough info here to provide a complete answer, but let me give you some background:

There will always be some hiss. This is due to general amplification where a small amount of noise is amplified along with the general signal. In most cases, the signal is strong enough to overpower any noise that is present (vocals in your example). This noise should not be that noticable in normal cases. If there is an automatic gain control in the line, this could account for it as with "silent" times, the gain will automatically be increased potentially to the degree where the noise is noticable.

Barring that scenerio, if the input signal is too low, the overall gain necessary to produce reasonable volume at the speakers will also be such that the noise is noticable. In order to track this down, please provide details about the current setup including:

1) Microphone make and model being used
2) Input being used on the mixer
3) Gain level being used for the mic channel
4) Gain level being used at the master level.

Kpc10mp line out jack dos'nt work


These are hard to work on... but one possible thing is if you are using an XLR adapter that is going from balanced to unbalanced 1/4 inch plug. You need to go XLR to XLR on this one. The MONO adapters can ground out the signal as these things don't always drive balanced signals... The signals are also line level so one does NOT want to use an impedance converting adapter.
The preamp is mounted on the plate with the jacks and has pretty short leads that limits how far you can pull it out. Taking off the grille and removing the woofer to get access can be a pain, especially to get the grille back in with the rubber edging.
Of course there is always the possibilty that the driving op-amp on the preamp board could have been fried. Word of WARNING: Power ALL interconnected parts of your system from the SAME receptacle or source. Powering say a mixer from a receptacle at the back of the room and powered speakers from a receptacle at the front is a good way to have equipment fried by "ground bounce" on the power system. Run extension cord to your mixer from the front where speakers are powered!

HOW DO YOU TURN DOWN THE HISSING NOISE


You can cut the treble gain some BUT most importantly is to send adequate signal to this speaker so volume level does not have to be set high when sending LINE LEVEL signals to it. Hissing noise is a product of the statistical noise that occurs in electronics. Running any device at high gain invariably brings up the hiss level. Managing thee signal levels is the responsibility of the sound engineer.

ALSO feed ALL interconnected equipment from the same receptacle or power source, even if it means running a power cable to a mixer alongside the snake. ALWAYS USE BALANCED audio cables whenever possible.

Bought a powered monitor as it said to do in the owner's manual, even though I thought it was weird as you usually use a passive monitor with a power amp. Purchased Kustom 10" powered monitor, hooked...


You haven't mentioned what model and manufacturer the mixer is. I will have to guess and say that the monitor out on the board isn't providing signal to the powered monitor or the monitor out on your board is powered and is now damaged by plugging a powered monitor into it. Carefully reread your manual and determine if the monitor out on your mixer is powered or line level. Reread also and make sure that the signal you are monitoring is assigned to monitor out, levelled correctly etc. If you find that the monitor out is passive (line level) try hooking it up to an external power amp and speaker. A guitar amp will do for testing purposes. Start with a low input volume on the amp. Also make sure that if it is passive to use a shielded cable from monitor out to input. If your board has powered monitor outs you can use a speaker cable from monitor out to speaker input (non powered monitor speaker).
