Man... it is hard getting use to the noise the cooling fan on the KLV1000 makes when I key up I might have to buy a noise cancelling mic to use with it. The bad thing about it is... it is not practical to move the KLV away from me because It needs to be retuned whenever you change channels.
Does anyone else find this fan noise annoying or am I just picky??
But all in all I still like this amp. |

Cornbrown,
Your right,with the ready switch on it sounds lke a jet winding up whenever you key the mic.how much of a channel or freq jump do you make that you would have to retune it?in the time this one has been sitting here the load and tune knobs have been only turned once.I originally tuned it on ch 20 into a dummy load and the output difference between ch1 and 40 is pretty flat.I use the drive knob to vary the output,usually running it between 1 and 3.(leaning more towards the lower end)with 2 watts dk from the radio,drive set on 3,hi/lo switch on lo it will dk out about 150 and swing between 200 and 400.best way to make it last.I am really impressed with the klv1000 and rate it as possibly one of the best I have ever used.

It is indeed noisy when that fan kicks on. If your using a Silver Eagle mic or the like FORGET IT or plan on really fine tuning the mic gain and microphone. I did end up moving mine back to where I originally had planned for it to go and that helped.
Still think I would really like to have a X-Force, Dave Made, Fat Boy etc. amp with no tubes in it capable of SSB. Just turn it on and go - I like easy.
I am using the same mic you are, a Galaxy Echo Talk Lock and have it dialed in pretty well.
The amp for sure works but the tuning is something I am still getting used to and it indeed needs to be adjusted between channels.
I can tell you that 291's works for sure. Heard him Sunday, then he put it on set to low and heard him great. Think later he turned it to HI /HI 2 maybe as he blew me out of my chair - He was amazingly loud & CRYSTAL CLEAR not to mention hitting me with 9 S-Units. I hope mine sounds that good.

Tech 291.... I thought I had to retune everytime I change channel... Shows you how much I know... This being my first tube amp. I will tune your way and leave it and see what happens.
A local also has a KLV1000 and I can tell whenever he keys up... you can hear the cooling fan spooling up in the background.
Hey Sinker...The Xforce is nice and has easy operation. Just make sure you install a good low pass filter to use with it.(both amps) |

You also need a big powersupply to run a big amp. Lots of $$$$$$$$$ |

The XForce Sinker is talking about is a base unit... It plugs into your electrical outlet. no power supply needed. |

cornbrown, lkie 291 said, i to use a klv 1000, its the 4 tube model, but i tune for the middle of about 15 up and 15 down of the frequencys im going to use, and it stays with in close tolerances of the first tune!! like tune for ch. 20, i can use up to ch, 35 or down to ch,5 and it
stay close?? but mine starts to drop quick after that?? then it usually just takes a small adjustment on the 3 knobs to bring it back to with in use!!? mite be some differances in the amps, depending when bought?? i say this because both of the klv's ive had, the fan was not that noisey?? ive sold my 5 tuber, but it tuned like the 4 tube?? i think ive heard that the newer models have loud fans, but not being around any, i dont no!! ive had my amp for around 4+ years and still have the same tubes!! but i did put the russian selvitas in it!! runs alot cooler, and to me, the russian tubes are so much better built!! ok, off my soap box or ill just go on and on!!

Turn the mic gain down, If the fan is too loud then it is up WAY too far, your voice 1" away from the microphone should DESTROY all the fan noise. |

i agree with chad, alot of times, a fan noise problem exists only because the operator is trying to use the mic at arms length.
i know, i know, its "cool" to be able to key up the mic and not move your head.
BUT!
close talking your microphone is one of the big CB "secrets" of having loud audio. you know those guys that just boom into the room when they key up? they are speaking directly into the mic at a distance of less than three inches from their mouth.
i too, was once a huge fan of the "my mic is ultra sensitive but doesnt squeal mentality.
then i heard the YL talking on the base while i was in the mobile; doing just what i had showed her.
and she sounded kinda muddy, a little bit echoey, and i could hear the TV in the background very clearly. i came home and readjusted my mic gains, and told her to speak into the mic at a distance of about two or three inches and no more.
MAN! what a difference! she sounded like a pro instantly. have you ever heard the addage that moving six inches closer to the mic is the same as doubling your talk power? well its true!
when i got on the base that night; all my usual locals couldnt stop complimenting me on my audio and asking what i had done or bought.
since changing my talking habits, i get so many compliments on my audio, that it gets a little weird saying thank you so much. seriously!
i am now an avid close talker, my mic gains all rest around 12 o'clock, and i can get through pile ups simply because my voice sounds louder than others.
i could never talk on ch 6 or 26.835 if my mic was at arms length. my little two pill just wont cut it, but when i yell into that mic, they dont know that im not running 1000 tube watts!
try it, you'll like it!!!
or dont, to each his own,

Turning down the mic gain will definately help cut the fan noise in my transmit. Since I now know I can tune the KLV for CH20 an it will hold for 15CH up/down. I will be able to move it away from me. Trust me it gets old after keying up more than a couple times and have to listen to the fan start up then shut off with every key of the mic. |

KV said it in a great approach; someone has a little audio experience eh? Every time you halve your distance from a source you gain 6dB, it's the inverse square law, it also works for doubling the distance, so keeping the mic the same distance from the noise source and getting twice as close to the mic you can effectively lose 12dB of gain and still hold the same loudness level. BUT... Another gain is the fact that all microphones with the exception of a few broadcast mics exhibit what's called proximity effect. Any microphone that is NOT omni directional will have more low end as you get closer, this is why it is "muddy" if you are too close. It's all about knowing your microphone and how the ALC and compression works in your rig. This is why professional singers will be VERY picky about what microphone they use, because they have learned that certain make and model. It may not be the best mic, but it is the best for them. They will also carry their own often times.. This ensures that it is properly cared for, dropping a microphone can have extreme detrimental effects on it's performance. Incidentally if I go into a room wiht my band that has PA supplied I will ALWAYS bring in my own microphones. Not only does the singer know his mic but I also know what mine do on certain instruments and that they are cared for. Not only that it's tough to find a pub with large format side address condenser mics for my guitars  Makes a world of difference!

thanks for the flowers chad; i like your explaination much better! much more official.
...and arent mics kind of a personal thing? i used to always carry my own when playing out. i usually sang some back ups, and always had to practically eat the mic to get heard! and if you knew where my mouth had been! J/K! anyway, i have always thought about that, and stayed far away from anyone else's mic that i might be forced to sing through.
gross!
later, im done hijacking the thread,
