    Hi

    I ad here same post I send to ART if someone knows what is the problem here. Probably some kind of user error but I don`t know what is going wrong.. :bawl:

    email to ART:

    I have a little problem with my V3 studio preamp. I tried to google and search your companys homepage, but could not find the answer.

    I use V3 with my bass guitar as preamp and limiter. Limiter is
    excellent, but it has one major flaw. When I play first note with my bass it does not limit it, after that limiter works fine. If I stop playing for a while and start again, the first note is not again limited. (allso this anoying hum appears) I added picture from Audacity to help you understand what I mean. I played with even attack basic open A with limiter full. Preamp warmed up about few minutes before recording.
    Preamp tube inside is original but AC adapter is made by Alesis and gives out 9v ~ 0.78A 7VA. (that sould be enough).
    This is really big problem for me, cos I can`t use limiter setting
    live or I will destroy speakers with that first note.. :/

    The limiter is set to a very slow attack and release time. This is typical of old-style studio limiters like the Urei LA2A, and ART probably chose those settings to appeal to people who wanted that type of classic studio effect. Even though it is called a "limiter", it is useless for stopping fast spikes after a pause/rest.

    If the attack and release cannot be adjusted, then I would not use the ART for speaker protection. If the limiter features a side-chain trigger input then while recording you can use a steady input like the kick drum or high hat to keep the limiter over the threshold for peak limiting while you record the bass. If it doesn't have a sidechain then your only hope is to play steadily with no loud notes following a long rest. After a rest, play a low/moderate-level note to trigger the limiter, then play any stronger notes.

    Thanks for the replys!
    I actually got reply to my mail from ART as well.

    "It actually might be the supply rate. The limiter should be a brickwall, and very fast and should not let any transient through. But I seem to remember that we were packing a 1amp supply for units shipped overseas because the V3 took just a little more to power and seemed to affect the users in 220v land.

    I would try to source a 9v AC 1amp / 1000 milliamp supply and see if the issue rectifies itself.

    Really nice that they bothered to answer. Not so nice is that the powersuply didn`t help. :/ (used 1A suply from my rocktron preamp)
    I may have to use it just as tube preamp and forget the limiter for bass. (My brother has used the limiter for some rap vocal recordings and he likes it a lot.)
